One probably does not need to store vast quantities of data to get civilization restarted. For example, this book purports to be a good start:

I've seen it suggested that Gray's Anatomy would provide a huge amount of medical knowledge. A handful of statements like "sickness is caused by living creatures too small to see," "everything is made from tiny indivisible parts too small to see individually," something about basic physics (at the F=ma level), something about the scientific method, something about fertilizer, and then evolution and genetics, etc might save people huge amounts of effort rediscovering technology, medicine, and so on. There was an interview circuit a few decades ago where they asked dozens of famous scientists what one (or three?) books they would want to survive nuclear war, and they all made quite a bit of sense.

You could probably kickstart the industrial revolution with one 10x10x10 room full of well-preserved textbooks.

Continued carbon emissions are putting humanity on an irreversible course for planetary devastation. If you want to get an idea of what the real world implications we may see from the 2, 3, 4+ ... degrees C of warming we are headed for in the coming decades barring radical action, check out Mark Lynas' book Six Degrees: Our Future on a Hotter Planet

There are a few like this already but the one that sounds closest to what you're talking about is The Knowledge: How to Rebuild Civilization in the Aftermath of a Cataclysm by Lewis Dartnell. I'd start there for market research and ensure you're offering something in addition to this one.

That is advanced physics for you. If it were easy, there would be as many people in physics lectures as something like business administration. Most topics won't stick the first, second, or even third time around.

As for electromagnetics, I could recommend:

The Art of Electronics.


Years ago I got my 2 year degree in electronics. Afterwards I ran across this book and it filled in ALOT of blanks with more layman explanations.

u/soundcult · 26 pointsr/synthesizers

Hey! I can relate exactly to where your'e coming from. I, some years ago, decided I wanted to get into building synths. I ended up getting a job at a pedal company and have spent more time learning to build and repair pedals than synths. I don't work there anymore, but it gave me a lot of perspective into the field as we also made euro-rack modules.

First up: I don't want to scare you off from this, but just want to give you a realistic perspective so that you go into this knowing what you are getting into. Making synths is hard and it's expensive. As far as electronic projects go, making a synthesizer is up there on the list. I've repaired powerplant turbine controller circuitboards that were simpler than some of the synths I've owned. This isn't to say, "don't do it!" but, expect to learn a lot of fundamental and intermediate stuff before you ever have something like a fully-featured synth that you built in your hands.

It's also expensive. A cheap synth prototype is going to cost a couple hundred bucks, easy, while a more fully-featured prototype could cost into the thousands to produce, and that's just to build one working prototype. If you want to make a run of products you're going to need money up front, and not a small amount. So, just be prepared for that inevitability.

One final note is that my perspective is broad (digital and analog) but is rooted in analog electronics because that's where I started. This isn't the only path you can take to get to where you want to go but honestly in my opinion, even if you're going to go mostly digital later, you need to understand analog.

If you have never messed with electronics much before I highly recommend the Make: Electronics book. I'm a hands-on person and this was the most effective book I found that let me study electronics fundamentals the way I wanted to; by making stuff! No matter which direction you go on (digital, analog, hybrid, DSP, SID, etc) you're going to want to know how to pick the right resistor, or how to pop an LED into a circuit, and this book will teach you that.

Solid follow-up books from there are Make: More Electronics, Practical Electronics for Inventors, How To Diagnose and Fix Everything Electronic, and The Art of Electronics. All of these books are good books that touch on different concepts you will find useful, so I encourage you to look through them and decide for yourself which of these interests you.

Around this same time, I'd encourage you to start getting into kits. Honestly, before you build anything synth, I'm going to recommend you build some pedals. Effects pedals are fun and rewarding to build without being too hard. Start with a distortion circuit and work your way up from there. Once you can build a delay pedal without freaking out, move on to euro-rack kits, or other synth kits. While you're building these kits, don't just build them, play with the circuits! Try swapping components where you think you can, or adding features. One of my first kits was a distortion pedal with a single knob, but by the time I was done tweaking on it it had five knobs and two toggle switches!

Once you're feeling somewhat comfortable with electronics, then you can dive into the holy grail of analog synth design: Make: Analog Synthesizers this amazing book was written by the brilliant Ray Wilson who recently passed away. His life's goal was to bring the art of building analog synths into the hands of anyone who wanted to learn, and there is no better place to receive his great wisdom than this book. You should also check out his website Music From Outer Space along the way, but the book covers so much more than his website.

If you make through most or all of those resources you are going to be well-equipped to take on a career in synth-building! I'm personally still on that last step (trying to find the time to tackle Make: Analog Synthesizers) but hope within the next year or two to get that under my belt and start diving in deep myself. It's been a fun journey of learning and discovery and I wouldn't trade the skills I've gained in electronics for much.

Hope this helps, good luck!

If I recall correctly, in Pale Blue Dot, this question is answered in this way: It is very expensive and somewhat dangerous to send a person to the moon/space. You have to have a ton of life supporting equipment, and also have to have the equipment to return the person home. It is much safer and less costly to send robots out into space for scientific research, and leave them there - they can stay out there for years.

u/hypnosifl · 22 pointsr/slatestarcodex

Climate scientist Michael Mann criticizes several of the claims in the article as overstated in this facebook post, though like most scientists he agrees with the general point that the consequences of climate change will be dire unless we take serious action (he has a book for non-scientists outlining the dangers and the politicization of the issue, The Madhouse Effect). And if anyone's interested in a book focused specifically on the best scientific predictions about the consequences of various amounts of warming, you could check out Six Degrees: Our Future on a Hotter Planet (see this post from one of the climate scientists on the blog, which gives it a positive review and says it accurately reflects the scientific literature on future scenarios).

I think our best chance of avoiding disaster lies in some combination of moving over to renewables and/or nuclear within the next few decades combined with massive production of carbon capture devices in the second half of the century, which could allow us to keep the warming to around 2 degrees or less. One important point is that without such massive deployment of carbon capture we don't really stand a chance of keeping it that low--check out the graphs here where the first two graphs show how fast carbon emissions would have to go to zero without any carbon capture if we want to keep warming to 1.5 degrees or less, along with a third graph showing how the decline can be more gradual if we have negative emissions later. The graphs are based on the "carbon quotas" for different amounts of warming on p. 64 of this IPCC report, and the quota for 2 degrees is not that much larger than 1.5 degrees (2900 gigatons vs. 2250 gigatons, only 29% larger) so the corresponding graphs for keeping it under 2 degrees wouldn't look too different.

The cause for hope here is that prototypes for carbon capture devices that remove CO2 much more efficiently than trees have already been built, see this article and this one, along with this interview with a physicist involved in the research where he makes the following point:

>My hope would be that we then would have a device that can take out a ton a day of carbon from the atmosphere. If you take out a ton a day, you would need 100 million air capture devices to take out all the C02 that we putting into the atmosphere today. And I would argue that it would be a lot less than that because we would also be capturing carbon at the flue stack, and not making the C02 in the first place by developing solar and wind technologies. ... There are about 1 billion cars out there. We are building 70 million cars and light trucks a year. So that kind of industrial production is quite possible. Eventually we should be able to produce an air capture device for roughly what it costs to manufacture a car.

I also think that another reason to be hopeful is that we may in the not-too-distant future achieve full automation of the production process for most mass-produced goods, leading to the possibility of self-replicating robot factories (what Eric Drexler calls clanking replicators), and I think the effect of this would tend to drive down the prices of all mass-produced goods--including things like carbon capture devices and solar panels--down to barely more than the cost of the raw materials and energy that went into them, so large-scale production of any good would be much cheaper. I talked more about this idea here.

If youre asking a question about a resistor and an LED, I bet you will have more complex questions about EE topics as you go forward. The book is good for engineering minds that havent studied EE in my experience. Plus the book is pretty cheap for the amount of knowledge inside.

The Mis-Education of Mathematics Teachers made a huge impression on me, in particular its emphasis on content knowledge and the fundamental principles of mathematics. More recently, the following comment by Ian Stewart has persuaded me to put more emphasis on the visual aspects of the subjects I teach:

> One of the saddest developments in school mathematics has been the downgrading of the visual for the formal. I'm not lamenting the loss of traditional Euclidean geometry, despite its virtues, because it too emphasised stilted formalities. But to replace our rich visual tradition by silly games with 2x2 matrices has always seemed to me to be the height of folly. It is therefore a special pleasure to see Tristan Needham's Visual Complex Analysis with its elegantly illustrated visual approach. Yes, he has 2x2 matrices―but his are interesting. (Ian Stewart, New Scientist, 11 October 1997) (source)

u/TheNegachin · 16 pointsr/EnoughMuskSpam

I'll commend the added effort on this one and give it another once-over.

>Before the DC-X, nobody believed rockets could land themselves with precision and reliability.

I will have to mark this one with a big fat [citation needed]. Although I can't quite speak for the folks who worked rockets in the 90's, in principle I see little reason why seasoned experts would be inclined to think of the task as impossible. Intriguing perhaps, difficult certainly, but the problems involved in that kind of landing functionality are well-defined in the propulsion and control theory literature from which a solution must be derived.

What the DC-X provides is an important proof of concept - I see little benefit in trying to analyze how useful that design is relative to any other given one. Although, as a point perhaps of historical interest: there was a "Delta Clipper" full-size vehicle in the plans as a follow-on to the DC-X, with some rather familiar promises of low-cost access to space and large savings through reusability. Some things are just posters, some things become prototypes, and some things end up as something more - that's the reality of aerospace designs if not engineering designs in general. I do have to say that based on the studies I've seen from the 90's, shelving the Delta Clipper concept was definitely the correct decision at that time.

>At this point, reuse was likely not saving over a couple million per launch, as pre-B5 boosters were not optimized for reuse.

I would like to draw attention to a pattern of thought I've coined "the refinement fallacy." That is, the general assumption that the next version will iterate away the relatively fundamental problems with this one. Although the next version could certainly support improvements, it's easy to assume that such improvements will lead to radically different performance even when there is little evidence to support that that is the case. Bottom line: improvements and refinements do not by default resolve fundamental problems.

For the next segment, I'd like to start by collecting a couple of questionable assertions:


>Musk said that reuse was 50% cheaper, however, by the end of this, it would likely be more accurate that the final pre-B5 reuse only saved up to 30%, and that was the expectation from B5.


>Block 5 is the final version of Falcon 9. It is reportedly built for 10 flights with minimal refurbishment and 100 flights over its lifetime, although there is speculation that B5 will be used through 200-300 launches IF Starlink becomes a thing.


>All of these help improve rapid reusability and the amount of times a booster can be used. it is likely only now, when B5 is being mass-produced (in rocket terms) and reuse is down that reuse of the booster can create cost saving with reuse being worthwhile. This is also the point where that 50% savings over making a new one can be reached, which would probably give up to 25% total cost reduction (this takes into account the costs of maintaining and using the ships and their respective equipment).

The problem with each of these claims is largely the source material: not what the average individual would describe as credible. The first and third claims seem relatively tame on their face - statements of economics and of the efficiency of a certain project. The second one is significantly more absurd - one that couples absurdly optimistic performance assumptions with associated claims of economies of scale. Generally, it's easy to make anything seem feasible if you take highly optimistic assumptions about future growth and best-case performance, and that can honestly be somewhat meaningless.

In truth, we have a credibility problem to address here. We don't have detailed financial information about a private company's business, so we have to look at the evidence we do have:

  1. Significant economic benefit is claimed. It's not a bad first-order assumption to take such claims at face value, although it might not be a bad idea to have some degree of skepticism, especially if the company in question is known for hyperbole and showmanship.

  2. Known financial results do not paint a particularly flattering picture. Incomplete a metric though this may be, very large and important efficiency gains would generally lead to a very healthy bottom line. This doesn't seem to really be the case at the moment.

  3. Studies from other individuals external to the claimant on the viability of the approach. Although there is some contention here, the external studies largely seem to be far more reserved in their claims on economic benefit. Though individually there is some question of credibility, when many parties independently reach the same conclusion it might beg the question of, why? Although it is far from proof, multiple experts corroborating the same story do make a case.

    The lack of verifiable numbers, and the consistent rightward shift of the "next iteration will wave a magic wand and erase the problems" mentality is a key facet of the refinement fallacy approach to these topics. Although there is not exactly hard proof available one way or the other (which does leave lots of leeway for speculation), the partial evidence provided does provide sufficient room to warrant significant skepticism.

    >A common rebuttal to reuse and SpaceX making money is that ULA makes way more profits than SpaceX. While true, this statement does not take into account the lower prices that SpaceX offers compared to ULA and where that money is going.

    What is perhaps more meaningful here is the matter of structural profitability. Generally, more budget services do make a smaller per-unit profit than the more expensive units; the former makes up for the difference in volume. But more meaningful is the more fundamental factors: is the business, including its forward-looking development plans, funded primarily by its operating profits, or by an influx of external capital? Investment is always a staple of large capital expenditures, but there is a massive difference between supplementing a healthy business profit with some external cash for faster development and relying on that money to just keep on top of the current batch of tasks without clearly achievable milestones to turn the trend around (often depending instead on pie-in-the-sky promises of grand successes). One may ask, which do we actually see here?

    >Currently, SpaceX is the only launch provider with commercially viable reusable launch vehicles. But it won't be that way much further into the 2020s. Future competitors include: Blue Origin's New Glenn, ULA's Vulcan-Centuar, and possibly China and India.

    Launch vehicle reusability has been a long-pursued topic in well-developed space programs all over the world. That has been the case for many decades, it will continue to be the case for years to come. However, two things become quickly clear:

  4. It doesn't mean that it will prove to be a value-added pursuit; they could just as well explore that option until it becomes clear that the benefits are not sufficient to implement it further.

  5. It doesn't mean that the task is a priority; research and opportunities for potential improvement that may only materialize years or decades into the future are staples of the R&D core of space, but it's no guarantee that any certain approach matters sufficiently to emphasize it right now. For example - the detachable engine idea had long been theorized and explored in detail, and may even prove to be viable, but is a far lesser concern than many more immediate factors of rocket design.

    Bold claims about a radically different future generally are far too presumptuous, assuming a world of highly optimistic possibilities without sufficiently considering the more immediate (and generally more mundane) economic and political conditions under which they operate. Again, some things end up as just proposals or prototypes, some things become something more; what a different world we would live in if all the promises of the past decades came true. The best-laid plans of mice and men often go awry.


    Just me, but I do have a book recommendation: Fundamentals of Astrodynamics - a fairly elementary, but highly informative, book on the principles of orbital mechanics. Great both for learning the basics at an engineering (as opposed to hobbyist) level, and as a reference if you happen to work with the stuff on a daily basis.
u/[deleted] · 15 pointsr/Physics

Griffiths for Quantum Mechanics and E&M

Taylor's Classical Mechanics

Kittel & Kroemer for Statistical Thermodynamics

These are the only ones I can attest to personally, they're for undergraduate level understanding. Kittel&Kroemer can seem dense and difficult to understand at first, but once you work through problems and spend time on each chapter, it will become apparent how efficient the book is.

>but I'd highly recommend getting a decent grammar book and learning English grammar properly.

Strunk & White - The Elements of Style. It's cheap (and probably available at damn near any library), you can probably read it in a day, and it will cover the bases for most things you'll need if you're not being explicitly tested on the fine details of the language. If OP is still in school, it's also very, very likely that at least one English teacher in their school has a copy.

You can read the original text by Strunk here for free, if you're seriously hard-up for cash. It is now nearly a century old, but it's still a fine reference.

u/unusualHoon · 13 pointsr/AskElectronics

Personally, I think the best place for a lay-person to start getting a technical grasp of electronics is from the "Navy Electricity and
Electronics Training Series" (NEETS) modules. The modules don't always describe the electrical behavior in a rigorous physics/engineering based way, but instead, they provide more practical explanations and applications. The best part is that they are freely available here.

As a next step, the standard go-to book is The Art of Electronics, which while it is a little pricey, covers a greater breadth of topics at a greater depth.

edit: typo.

u/BrotherCorvus · 13 pointsr/electronics

It's a fantastic book. No need to get all of them though, this is a pic of the third edition (2015), the second edition (1989), and the first edition (1980). You can skip the first and second.

u/CD_Johanna · 12 pointsr/math

If visualizing complex analysis is your thing, I'd suggest "Visual Complex Analysis" by Tristan Needham.

u/ALooc · 12 pointsr/NoSleepOOC

I took a look at your previous posts, here some pointers.

First: Basics.

  • Formatting - make your text readable by using paragraphs. Press Enter TWICE to make a line break on Reddit - else most people will just skip over your posts.
  • Use proper grammar and sentences - e.g. a slash doesn't belong in your story ("restaurants/fast food places"). Use an "and" or "or" instead.
  • Spellcheck - "resturaunts". If you want people to read your stories you have to do them the favor of proofreading your own posts. At least use Word, LibreOffice or Google Drive to write your stories, they have a spellcheck built in.
  • Make it a story. Think of books; a book never starts with "Alright. So a little backstory" and then goes on to excuse that "The backstory is longer than the actual story, sorry." Instead start the way a tale would be told. Start with action or at least an image that the reader can see and feel.
  • Use written language, not spoken language and style. Cut out words like "alright", "so", that are mere oral filler words and shouldn't appear in written text (unless appropriate). Words that don't add meaning should not be in your writing.

    Second: Writing.

  • Story flow. Honestly I don't understand your last story. There are too many breaks in continuity and too many unnannounced location and character switches.

    > Mom walks up to me and says I looked a little disoriented, and I just say its nothing. I don't know why, but that creeped me out.

    What creeped you out? Your mom's asking you? Or the events before?

  • It would be good if you read some more fiction and try to look out for basic writing standards. Again line break, this time for dialogue. Dialogue without line break is very hard to read.

    > "Hey! I thought it would be fun to go see a movie, so we are going to the 10 o'clock showing of the new star trek movie tonight. I can't wait to see you and your brother again." He said. "Wow. Okay..." I said. Not even a hello or goodbye.

    much easier:

    > "Hey! I thought it would be fun to go see a movie, so we are going to the 10 o'clock showing of the new star trek movie tonight. I can't wait to see you and your brother again." He said.

    > "Wow. Okay..." I said.

    > Not even a hello or goodbye.

    Lastly: Make us hear and feel things. Give us a chance to feel what you feel

    > When I hear tapping. And then water. Then, without warning, the toilet flushes in a bathroom that has always been manual flush. I hear walking, she shadows, the lights flicker, and I hurry up to wash my hands and get out.

    This should be three or four paragraphs rather than four sentences. Where does the tapping come from? How loud is it? How did you notice it first?

    What does "And then water" mean? You heard water flowing somewhere? You saw water on the floor, running into your stall?

    You hear WALKING and you tell us nothing about it? Silent? fast? did you see feet? Did it sound like bare feet or hard soles?

    You need to paint a picture that we can see, hear, smell and touch.

    That is the actually my main point: How to format your writing and spellcheck should be the minimum and are required for any story to be worth reading. Learn that, there is no way around it. Look at stories you like and see why they are good - your formatting should never be in the way of your story.

    But what you need to practice is to paint that picture. Try to sit down and describe one simple mundane thing. Try to describe, as in-depth as possible, what it feels like to sit on your chair. Describe the scene you see out of your window - not just "there's a house", instead make that house visible for someone thousands of miles or hours away. Try to describe what your mother's footsteps on the corridor sound like. Where are they? How does the volume change? Are they hurried or does her heel strike the floor hard? Are they louder if she carries heavy objects?

    When you are able to do that you can take the stories you wrote and develop them from a summary of your experience into a full-blown story. Tell the tale, and of course feel free to add some more fiction to make it creepier. Maybe you did see feet, or maybe you did hear something soft rubbing along the window or door or maybe even your stall. Don't limit yourself to "reality".

    tl;dr (1) Learn proper formatting - simply by reading more and by trying to figure out when and where it works and when and where it doesn't. Look at a book or story you enjoy and see how the paragraphs are layed out. Also get yourself a copy of Strunk & White. (2) Practice painting that picture (in all senses, not just visually). Then you will get places :)

It's cheap too.

u/sheepson_apprentice · 12 pointsr/programming

Well, electronics is a huge field, and especially if you're going to get into software radio, basic fundamentals of amplifiers and modulation techniques is a must. Don't get discouraged though, internet is abound in information.

Here are some books that may help to start:

The Art of Electronics

Especially if you can get the used Cambridge Low Price Edition. Either way, it's a good book for fundamentals, a classic too.

This book is ok:

Communications Receivers

For general electronics knowledge, some undergrad EE textbooks are solid gold.

Here's one that's great:

Circuits, Devices and Systems


Another excellent resource for folks dabbling in electronics are these free simulators:

Paul Falstad's Circuit Simulator


The above are great before one gets to dip into SPICE.

Your post has too little context/content for anyone to give you particularly relevant or specific advice. You should list what you know already and what you’re trying to learn. I find it’s easiest to research a new subject when I have a concrete problem I’m trying to solve.

But anyway, I’m going to assume you studied up through single variable calculus and are reasonably motivated to put some effort in with your reading. Here are some books which you might enjoy, depending on your interests. All should be reasonably accessible (to, say, a sharp and motivated undergraduate), but they’ll all take some work:

(in no particular order)
Gödel, Escher, Bach: An Eternal Golden Braid (wikipedia)
To Mock a Mockingbird (wikipedia)
Structure in Nature is a Strategy for Design
Geometry and the Imagination
Visual Group Theory (website)
The Little Schemer (website)
Visual Complex Analysis (website)
Nonlinear Dynamics and Chaos (website)
Music, a Mathematical Offering (website)
Mathematics and its History
The Nature and Growth of Modern Mathematics
Proofs from THE BOOK (wikipedia)
Concrete Mathematics (website, wikipedia)
The Symmetries of Things
Quantum Computing Since Democritus (website)
Solid Shape
On Numbers and Games (wikipedia)
Street-Fighting Mathematics (website)

But also, you’ll probably get more useful response somewhere else, e.g. /r/learnmath. (On /r/math you’re likely to attract downvotes with a question like this.)

Buy yourself of copy of the art of electronics. Pick one or two topics from that book every day and read about them. It covers pretty much every aspect of EE without going into an insane amount of detail. Use that to narrow your focus once you find something that really interests you. EE is a huge area of engineering and you’re not gonna like all aspects of it but the art of electronics is a great start.

The Art of Electronics

Edit: to add on to this. Adafruit has a ton of more entry level friendly tutorials and stuff. Find a component on their store and they’ll have tons of projects and tutorials using those components. They don’t get much in to how it all works. You’re going to have to read for that. Kahn academy is pretty good at explaining stuff too.

Machinery's Handbook. I'm an ME student and my dad's an ME. He gifted me this saying it was an important reference book and he was not wrong.

u/drepamig · 10 pointsr/engineering

Shigley's is great for learning how to design and why you design the way you do. It's the book I used in college and still reference at work. I'm not so sure it'd be great for a novice engineer. For a more practical approach, I'd recommend a few below (not necessarily in this order):

  1. Machinery's Handbook - This is regularly seen as the [mechanical] engineer's bible. It has nearly everything you'd need to know for design. Most of the machinists used this in a shop I used to work in. Nearly every engineer in my current job (and there are a hundred or more) have a copy of this at their desk.
  2. Pocket Reference - This is kind of (loosely) like Machinery's Handbook but much more broad. It covers a little bit of everything from engineering, to vehicle maintenance, to plumbing. I like it for it's all-around information.
  3. Handyman In-Your-Pocket - this is by the same author as #2 but is tailored to the building trades. I also have this but I haven't used it much yet. Not because it's not useful, just because I haven't gotten around to it.
  4. Marks' Standard Handbook for Mech. Engineers - I have an old copy of this book from the 80s, I believe, that my dad gave to me. It is also on the same order as Machinery's Handbook, but instead of covering EVERYTHING, it goes into more depth about the topics it does cover. If I remember correctly, it covers topics ranging from how to make a weldment to how to design a power generating steam boiler and turbine.
  5. Solutions to Design of Weldments - This is a new one to me. I recently went to the Blodgett Welding Design Seminar and this was one of the reference materials they handed out. I had a few text book sized design guides by Omer Blodgett that I've often used, but this one seems to take all of the info from those books and condense it down to a handbook. Best part is that it's only $3.50 for a copy and I think (but I'm not sure) that it ships for free.

    A nice free reference manual that includes all sorts of design equations is the NCEES reference handbook. I used it back when I took my FE exam (the first exam you take before you become what's call a "Professional Engineer" in the US). It's a nice PDF to have around, though it doesn't go into a lot of explanation as to what the equations are.

    A few web resources I use are:,

    I'm sure I'll think of some more and, if I do, I'll update this post.

    Hope that helps.

A few degrees warmer is about how much we can stand. So, with that few degrees comes at least a few feet of sea level rise, likely more. So coastal areas that tend to be the highest populated, are going to need to retreat from the coast. That's going to be a huge economic burden. How is that burden born? Best left to economists I suppose....

Also, California and the west will tend to get drier, which will affect agriculture and I would venture agricultural costs. The mid-west is also slated to become drier, this is at a time when the Ogallala aquifer is being sucked dry, so we are going to be running out of a pretty precious resource in large chunks of the US. Further abroad, with melting glaciers hundreds of millions may be left without water. The middle east is supposed to also dry up. This is likely to create a humanitarian crisis.

There could be significant changes in disease distributions as well. With things like malaria, Zika, etc. becoming more prevalent in the US because of a spread of their vektors (e.g., certain tropical mosquito species).

Depending on the severity, much of the Amazon rain forest may dry out, though there is some good debate around that topic. Coral reefs laregly won't be able to keep up, which could crash some fisheries and ecosystems. Forest diseases may be more prevalent (e.g., emerald ash borer in the eastern US that is wiping out ash trees), and extinction rates are thought to spike, with 20-30% of species at risk of extinction.

Check out a book 6 degrees. I haven't read it yet, but it's on my wish list - supposed to be a good run down of the catastrphe that 6 degrees of warming will bring - basically an end of civilization as we know it. Some respected scientists think that the population will end up crashing to 1 billion in the next century..... that will cause some chaos...

Six Degrees by Mark Lynas. Great book, he read 3000 papers on the effects of climate change and summarized them, with extensive references. One chapter per degree C.

At 3C it just looks disastrous. At 4C the survival of modern civilization starts to look doubtful. At 6C it's hard to imagine our species surviving to any meaningful extent.

Learning electronics is a lot like music. There is an insane amount of information, but if you get an economic working knowledge under your belt, you can really do some amazing things. In order for you not to get lost in the rabbit hole, I will provide you these methods of learning practical hobby electronics.

First, is simply just a suggestion. There are two "domains" of electronic thinking and analysis: digital and analogue. Fuck analog right in its dumb face. The math used in analog is fucking super duper hard, and analog circuits are prone to interference problems. Digital is where you want to be. It's vastly simpler to use programmable digital parts, and analyze digital circuits. Don't get lost in AC equations of capacitor, or the god damned transistor equation (seriously, fuck that. )

Okay here is how I learned hobby digital electronics:
First buy this, and go through all the examples in the workbooks. When you learn electronics you 100% HAVE TO DO HANDS ON LEARNING! DONT LEARN IT FROM A BOOK! MAKE CIRCUITS!

At the same time, read this (which is a good topical explanation, and free):

And buy and read this (which is an EXCELLENT formal introduction into the physics):

Also you are going to learn how to program, which is an entirely different topic. Programming and hobby electronics make you a master of the universe, so it's worth it. I learned programming in the electronics domain and it was awesome. I made a microcontroller FM synthesizer:

So basically, the way I learned programming in general was self-teaching with books. Again, you have to do it hands-on. Actually complete the examples in the books, and you'll be fine.
First, learn procedural c programming using C primer plus. Buy an older version so it'll be super cheap:

Next, learn Object oriented programming using head first java. They do a great job of tackling OOP, which can be a difficult thing to learn.

You're overwhelmed because they're deep topics. But, seriously, its the most fun shit ever. You'll love learning how to do it.

u/lkesteloot · 9 pointsr/AskElectronics

No, neither this book nor The Art of Electronics is good for beginners. I recommend Practical Electronics for Inventors. (Ignore the "Inventors" part, the book has nothing to do with that.)

u/desquared · 9 pointsr/math

u/charugan · 9 pointsr/writing

u/Beagles_are_da_best · 9 pointsr/PrintedCircuitBoard

I did learn all of this stuff from experience. Honestly, I had a little bit of a tough time right out of college because I didn't have much practical circuit design experience. I now feel like I have a very good foundation for that and it came through experience, learning from my peers, and lots of research. I have no affiliation with Henry Ott, but I treat his book like a bible . I refer to it just about every time I do a board design. Why? because it's packed with this type of practical information. Here's his book. I bought mine used as cheap as I could. At my previous job, they just had one in the library. Either way, it was good to have around.

So why should you care about electromagnetic compatibility (EMC)? A couple reasons:

  1. EMC compliance is often regulated by industry and because a product requirement. The types of tests that your product has to pass is dependent on the industry typically, but in general there are tests where bad things are injected into your board and tests where they measure how noisy your board. You have to pass both.
  2. EMC compliance, in my opinion, is very well correlated with the reliability and quality of a product. If a product is destroyed "randomly" or stops working when the microwave is on, you're not likely to have a good opinion of that product. Following guidelines like the one I did above is the path to avoiding problems like that.
  3. EMC design is usually not taught in schools and yet it is the most important part of the design (besides making it perform the required product function in the first place). It also is very hard to understand because many of the techniques for improving your design do not necessarily show up on your schematics. Often, it's about how well your layout your board, how the mechanical design for the enclosure of your board is considered, etc.

    Anyways, it's definitely worth looking at and is a huge asset if you can follow those guidelines. Be prepared to enter the workforce and see rampant disregard for EMC best practices as well as rampant EMC problems in existing products. This is common because, as I said, it's not taught and engineers often don't know what tools to use to fix it. It often leads to expensive solutions where a few extra caps and a better layout would have sufficed.

    A couple more books I personally like and use:

    Howard Johnson, High Speed Digital Design (it's from 1993, but still works well)

    Horowitz and Hill, The Art of Electronics (good for understanding just about anything, good for finding tricks and ideas to help you for problems you haven't solved before but someone probably has)

    Last thing since I'm sitting here typing anyways:

    When I first got out of college, I really didn't trust myself even when I had done extensive research on a particular part of design. I was surrounded by engineers who also didn't have the experience or knowledge to say whether I was on the right path or not. It's important to use whatever resources you have to gain experience, even if those resources are books alone. It's unlikely that you will be lucky and get a job working with the world's best EE who will teach you everything you need to know. When I moved on from my first job after college, I found out that I was on the right path on many things thanks to my research and hard work. This was in opposition to my thinking before then as my colleagues at my first job were never confident in our own ability to "do EE the right way" - as in, the way that engineers at storied, big companies like Texas Instruments and Google had done. Hope that anecdotal story pushes you to keep going and learning more!
u/LtPlatypus · 9 pointsr/machining

Machinery's Handbook - 30th Edition. It's commonly referred to as the "Machinist's Bible". It's not so much an instructional book as it is a reference; however, I've learned so much from it. It's got detailed information on taps and dies, milling, turning, welding, heat treating, machine shop economics, mechanics and physics, measuring, properties of materials, and I could go on. It's kind of expensive, but it really is worth every dime. Look around online for good deals, I got mine (30th Ed - Toolbox Edition) for about $65 new on The only differences between the Large-Print and the Toolbox-Edition are the size of the book and the size of the print. The full size book is 7"x10" with larger print, and the toolbox is 7"x4.5" with fairly small print. They both have the exact same content. If you have poor vision, buy the full size for sure. If you're going to be a metalworker for a living, or even just a weekend machinist, you'll keep this book for the rest of your life.

Old retired guy here......

On my bucket list, I thought I'd take a shot at learning some physics from the bottom up. Here are some observations from someone who tried to learn it without any worries about needing it for a major or trying to get into grad school.

First, elementary physics labs stink. Sometimes you get stuck with a bad lab partner. Other times the equipment is in really bad shape and simply will not work so that the experiment will do what it is supposed to do. If you get a lab assistant who does not know what he/she is doing - and there are quite a few of those - you can forget about a decent lab experience.

Second, intermediate physics labs can be great. I was teamed with an undergraduate I still refer to as Mr. GoldenHands. He could make any piece of lab equipment do what he wanted it to do and what it was supposed to do. I would do calculations and draw graphs while he got the data out with only a little help from me. Furthermore, the lab assistant we had was actually a full professor of physics who was an experienced experimentalist. What my partner did not know about the equipment, he did. Great course.

Physics exams are unnecessarily hard. In a Mathematics exam, students are usually asked about material they have some shot at solving. They will be asked for definitions or statements of theorems that they have seen. They will be asked to answer questions about material they already have seen. In a physics exam, you will get a question completely out of left field that seems to have no relation to anything you have studied previously. No wonder average grades on exams sometimes in the thirties or forties.

Physics professors in undergraduate classes frequently have curricular tunnel vision. "This is the mechanics book. I will go through the book chapter by chapter frequently skipping chapters I do not like. If somebody ask me a question I can not answer such as 'What is the difference between the Lagrangian and Newtonian formulations of mechanics and why is one preferable to the other?' I will brush it off."
(I actually asked this question and got brushed off.) Don't do that!

SLOW DOWN!!!! Physicists seem to be very interested in moving through a course at a breakneck pace that does not allow for any time for internalizing a subject. I'll give an example. Look at Introduction to Electrodynamics by David Griffiths. On page ix of the third edition, Griffith's says that the book can be covered "comfortably in two semesters." A little later, he talks about one semester courses finishing chapter seven. OK. I took a one semester course from that book. The professor skipped chapter one - it was only mathematics, so that was ok by me - and then went like a house-afire and ended the first semester at the end of chapter 10. He did not make any attempt to make the material intuitive. (I had a terrible time with current density.) He just motored through it symbol by symbol and expected everybody to understand. We didn't. (I am going to take another course in electrodynamics at another university some day just so I can understand Maxwell's equations. For me there is nothing riding on this except intellectual curiosity. For other undergraduates, the type of course I just described was a killer.)

I'll stop now but I am sure there are other who could chime in with other problems.

Bottom Line: I like physics and I intend to learn more, but physics teaching should change.

You have to "bootstrap" somewhere. At the VERY bottom is generally NOT a productive or practical way to do it. We used to have a joke in EE school: "If want a good laugh, ask a physicist to design a circuit for you". The reason it's funny is they'll start designing from quantum mechanics or Maxwell's equation as they usually don't ever learn all the tricks we have in EE to "short-circuit" the process.

Basically start with analog circuits (Ohm's law) for DC, advance to AC and then to circuits and systems. You can go deeper but at the start frankly most people will get wrapped around the axle and give up first.

Everything from Grand Unification up to your iPhone is built on approximate models with assumptions that are not strictly correct all of the time if ever. In electronics you have circuits bounded by Quantum Mechanics and Maxwell's Equations as "actual physics". You can't actually use these for 99% of anything practical so these are not the best starting points.

Instead you use approximate models like Lumped Equivalent Model (which is what resistors, capacitors and inductors are: that resistor in your hand - it's not real - just an approximation). But you don't really want to learn that up front.

However if you want a reference that goes into the physics of electronics I'd recommend The Physics of Information Technology. Not cheap so borrow it from a library first.

But ONLY use it when you get that itch to naively dig into the physics for a quick dip or overview or orientation. Otherwise use regular electrical engineering (EE) intro analog circuit textbooks or something like Horowitz' Art of Electronics

Unless you have a physics or engineering degree TPIT will still go straight over your head mostly (the author is an MIT professor and he relatively gentle by BSEE/BS Physics standards on the math but it's brutal if you haven't had several years of university math).

assuming you have all the fundamental physic, you can start with the textbook from allaboutcircuits's textbook. A introduction to electronic book. It is about 2000 pages covering all basics of electronics. I think it is a great read and easy to understand, written for beginners.

After that you should read Make:AVR programming. It is quite enjoyable read and I read it in 2 sitting. A computer engineering book specifically targeting microcontroller. And as the name imply, it is about 8 bit AVR which is easily the most popular arduino variant. It covers a lot of detail on microcontroller basics and underlying electronic concept and working principles.

To supplement the above book, read a atmel datasheet on one of their microcontroller (atmega328 is a good choice).

For optional knowledge you can try Make's Encyclopedia Of Electronic Components It basically covers all electronic components and introduce you to it. I didn't like too much because you cant read it as a book but should use it as a reference to a particular component you are interested it. It is a great way to broaden your scope on what components is available to you.

Then for the advanced stuff you can read the The Art of Electronics By many it is consider the holy grail of electronic textbook. But I think it is difficult to read without an formal EE education.

There's information on tolerancing and machining in The Machinery's Handbook especially. I'm not sure on other resources for those. There are books on manufacturing processes that'll discuss the tolerances capable and design limitations.

I polled Reddit once, asking which books everyone would recommend. This one was by far the most suggested, followed by Practical Electronics for Inventors.

The "... for Inventors" book is more something that you'd reference on an as-needed basis. Not as much teaching and instruction as this one.

u/miczajkj · 8 pointsr/askscience

Don't read Feynman. While it's extremely dense and good, it's also very unconventional and hard to understand if you don't know where it's going already.
I'd suggest Griffiths or Zee's Nutshell. While both are technically textbooks, i think you can read them very well without necessarily understanding all calculations.
Of course, those are damn expensive so you should better look for them in a library.

u/Snowtred · 8 pointsr/Physics

I would recommend Introduction to "Elementary Particle Physics" by David Griffiths

Its generally considered a higher-level undergrad book, but as a PhD student I still look at it from time to time, especially if I want to teach a specific subject. He will review the SR and Quantum for you, but at a level that you'd want to have seen it before. There's calc and a little bit of linear algebra, but at such a level that you could learn them for the first time through this text (assuming you've had SOME Calc before)

From there, the next level is sort of "Quarks and Leptons" by Halzen and Martin, which people are generally less excited about, but I enjoyed it.

After that, the top standard that even theorists seem to love is "High Energy Hadron Physics" by Martin Perl, where there are parts of that text that I still struggle with.

u/TexasNortheast · 7 pointsr/ElectricalEngineering

Get a practical electronics book right off the bat if you are into electronics. Something like this (or perhaps this):

Also note the price-tag. This book is a gem.

University textbooks often don't have the right mindset to them and now that I've finished my degree and out in the workforce I'm realizing this. You want a book that will actually teach you how to build something. The field of EE also loves to apply a whole bunch of meanings to a few terms, for example "electricity" and "grounding", which can very easily confuse and mislead beginners. Practical books tend to address these things a bit better in my opinion. This applies to any field - I'm an Industrial Engineer (power, motors, control, safety) and also own a book of this type on my field - here in Canada we have Techs and Engineers. The Techs tend to learn how to actually do things, and these are the types of books they read.

Regarding textbooks: something I've only discovered recently is buying Eastern Edition textbooks as they're much cheaper and essentially the same thing.

You can find formulas for gear force/strength in Shigley's. You kind of need to know the material properties to find out the max torque but you can just use a general steel.

I'd like to give you my two cents as well on how to proceed here. If nothing else, this will be a second opinion. If I could redo my physics education, this is how I'd want it done.

If you are truly wanting to learn these fields in depth I cannot stress how important it is to actually work problems out of these books, not just read them. There is a certain understanding that comes from struggling with problems that you just can't get by reading the material. On that note, I would recommend getting the Schaum's outline to whatever subject you are studying if you can find one. They are great books with hundreds of solved problems and sample problems for you to try with the answers in the back. When you get to the point you can't find Schaums anymore, I would recommend getting as many solutions manuals as possible. The problems will get very tough, and it's nice to verify that you did the problem correctly or are on the right track, or even just look over solutions to problems you decide not to try.


I second Stewart's Calculus cover to cover (except the final chapter on differential equations) and Halliday, Resnick and Walker's Fundamentals of Physics. Not all sections from HRW are necessary, but be sure you have the fundamentals of mechanics, electromagnetism, optics, and thermal physics down at the level of HRW.

Once you're done with this move on to studying differential equations. Many physics theorems are stated in terms of differential equations so really getting the hang of these is key to moving on. Differential equations are often taught as two separate classes, one covering ordinary differential equations and one covering partial differential equations. In my opinion, a good introductory textbook to ODEs is one by Morris Tenenbaum and Harry Pollard. That said, there is another book by V. I. Arnold that I would recommend you get as well. The Arnold book may be a bit more mathematical than you are looking for, but it was written as an introductory text to ODEs and you will have a deeper understanding of ODEs after reading it than your typical introductory textbook. This deeper understanding will be useful if you delve into the nitty-gritty parts of classical mechanics. For partial differential equations I recommend the book by Haberman. It will give you a good understanding of different methods you can use to solve PDEs, and is very much geared towards problem-solving.

From there, I would get a decent book on Linear Algebra. I used the one by Leon. I can't guarantee that it's the best book out there, but I think it will get the job done.

This should cover most of the mathematical training you need to move onto the intermediate level physics textbooks. There will be some things that are missing, but those are usually covered explicitly in the intermediate texts that use them (i.e. the Delta function). Still, if you're looking for a good mathematical reference, my recommendation is Lua. It may be a good idea to go over some basic complex analysis from this book, though it is not necessary to move on.


At this stage you need to do intermediate level classical mechanics, electromagnetism, quantum mechanics, and thermal physics at the very least. For electromagnetism, Griffiths hands down. In my opinion, the best pedagogical book for intermediate classical mechanics is Fowles and Cassidy. Once you've read these two books you will have a much deeper understanding of the stuff you learned in HRW. When you're going through the mechanics book pay particular attention to generalized coordinates and Lagrangians. Those become pretty central later on. There is also a very old book by Robert Becker that I think is great. It's problems are tough, and it goes into concepts that aren't typically covered much in depth in other intermediate mechanics books such as statics. I don't think you'll find a torrent for this, but it is 5 bucks on Amazon. That said, I don't think Becker is necessary. For quantum, I cannot recommend Zettili highly enough. Get this book. Tons of worked out examples. In my opinion, Zettili is the best quantum book out there at this level. Finally for thermal physics I would use Mandl. This book is merely sufficient, but I don't know of a book that I liked better.

This is the bare minimum. However, if you find a particular subject interesting, delve into it at this point. If you want to learn Solid State physics there's Kittel. Want to do more Optics? How about Hecht. General relativity? Even that should be accessible with Schutz. Play around here before moving on. A lot of very fascinating things should be accessible to you, at least to a degree, at this point.


Before moving on to physics, it is once again time to take up the mathematics. Pick up Arfken and Weber. It covers a great many topics. However, at times it is not the best pedagogical book so you may need some supplemental material on whatever it is you are studying. I would at least read the sections on coordinate transformations, vector analysis, tensors, complex analysis, Green's functions, and the various special functions. Some of this may be a bit of a review, but there are some things Arfken and Weber go into that I didn't see during my undergraduate education even with the topics that I was reviewing. Hell, it may be a good idea to go through the differential equations material in there as well. Again, you may need some supplemental material while doing this. For special functions, a great little book to go along with this is Lebedev.

Beyond this, I think every physicist at the bare minimum needs to take graduate level quantum mechanics, classical mechanics, electromagnetism, and statistical mechanics. For quantum, I recommend Cohen-Tannoudji. This is a great book. It's easy to understand, has many supplemental sections to help further your understanding, is pretty comprehensive, and has more worked examples than a vast majority of graduate text-books. That said, the problems in this book are LONG. Not horrendously hard, mind you, but they do take a long time.

Unfortunately, Cohen-Tannoudji is the only great graduate-level text I can think of. The textbooks in other subjects just don't measure up in my opinion. When you take Classical mechanics I would get Goldstein as a reference but a better book in my opinion is Jose/Saletan as it takes a geometrical approach to the subject from the very beginning. At some point I also think it's worth going through Arnold's treatise on Classical. It's very mathematical and very difficult, but I think once you make it through you will have as deep an understanding as you could hope for in the subject.

IMO you want Bate's Fundamentals of Astrodynamics.

I don't want to speak out of turn, as I wasn't alive at the time, but my professors claim to have learned everything on this bad boy. It's great for getting a grasp on the concepts and well worth the 15 dollar price tag even just to put on your shelf to sit there and look cool. I got it with that in mind and it's become my go-to. Admittedly, computational approaches have changed the standard regarding some of the info in this text but the core concepts are there and it makes the content approachable.

Whenever a movie is portraying a technical subject, they usually massacre the topic. I've a degree in Physics, I'm a computer techie for my day job, and I'm a huge science geek - so I cringe a lot at the movies. A LOT. Unless the most technical or scientific object in the movie is a stone hammer, in which case I may cringe only a little.

But whereas essentially all such movies get 100% of the technical topic wrong, Gravity is more like half-and-half. And the half that they "got wrong" was the one that would have made the movie boring and would have made large parts of the narrative impossible (or difficult to tell in a non-documentary). I was actually very impressed and excited with all the parts they got right. I loved it, all the while being very aware of the physical impossibilities popping up across the narrative.

Yes, I know about horribly expensive orbital plane changes, and Hohmann orbits, and the narrow re-entry window, and all that stuff, so don't even start it. If you want accuracy and physical realism, break out Fundamentals of Astrodynamics, by Bate, Mueller & White, and splurge on. But this movie ain't it, never was, never will be. And that's just the way things ought to be.


P.S.: The main topic of the movie was rebirth. Not gravity, not space flight. Rebirth. Learning to let go of past (as Clooney's character literally says at some point), and being born into a new life. There's even a fetal position with an umbilical cord somewhere in the movie (not literally, but broadly suggested by a lingering shot of Sandra Bullock), and then later all sorts of emerging from dark waters with red mud all around, in case the metaphor needed any more emphasis. It was not even too subtle.

As to what "gravity" is a metaphor of - well, it should be obvious by now.

I started with circuit bending. I took a student-taught class as part of the Oberlin College ExCo, which is the Experimental College, where any student can teach a class for a single credit, provided they can demonstrate to a faculty panel that they have something to teach and a plan on how to teach it. That got me started on instrument building, and also on circuit design. I worked on that as a hobby for several years, until eventually I was friends with some people who were getting into Eurorack manufacturing: the 4MS crew, when they were still in Austin. Ralph and Dan encouraged me to move from bending (and breaking) toys into creating circuits, and gave me a few good starting tips (and copies of a few Forrest Mims books, which are absolutely invaluable). Another year or two after that, I was talking with Mickey, and he mentioned that he had the good problem that his modules were selling too fast, and he was bored of soldering, and wanted more time to design. I piped up quick. "I know how to solder! I'm very good at it." The second part was a lie. It's true now, though! Everything more advanced that I know about circuits I've learned from Mickey, the internet, and a bit more book learnin', especially from The Art of Electronics. I told the story of getting started on the pedal (which was my first commercial pedal) elsewhere in this thread.

The biggest hiccup was finding ROHS compliant vactrols! But we're cool on that now. Thanks, XVIVE!

u/baldengineer · 7 pointsr/AskElectronics

Understanding a circuit does require understanding the fundmantal building blocks. For that, there is no better guide than the Art of Electronics. While you might find a guide that says, "this circuit works with a common emitter amplifier," you aren't going to find guides that alway explain those fundamental circuits.

That's where AoE comes in. All of the building blocks are explain in plain simple language. It is worth every penny and I recommend everyone who is interested in circuit design to have a copy. If you can get a good deal on the 2nd edition (e.g. half the price of the 3rd), then go that route. The vast majority of the information is still fine on the older book.

A couple of recommendations:

First, there are the classic Forrest Mims books they are the quintessential beginner level books. Radio Shack used to sell them. They are very introductory and tend to be rather brief for easy consumption. I'm not a huge fan of the style personally but others LOVE them a lot. Many many many hobbyists and engineers got their start with these books.

Another option I like a lot is Practical Electronics for Inventors, 3rd Ed. by Paul Scherz and Simon Monk. This book is a great beginners book that will take you nicely into circuit theory and things like that. Not as advanced as an academic tome but advanced enough for you to learn a good amount and establish a solid foundation.

Lastly, there is the very advanced Art of Electronics 3rd Ed. by Horowitz and Hill. This is the classic introductory text for engineers and hobbyists alike. It is very math heavy but you will have a very very good understanding of what's going on.

One non-book recommendation is the AllAboutCircuits online textbook tutorial. It is pretty well enumerated and detailed, though it is a bit lacking in sample problems. A great free resource that you can start learning now.

Beyond this, once you get a solid foundation. You can start focusing in specific areas like digital, power, precision measurements, etc.

Esse tipo de assunto não é tão "viagem" como muita gente pode pensar, pois desastres naturais e fim de civilizações acontecem desde sempre, o nosso período atual é que é anormalmente pacífico. Nos nossos tempos, futuro do meio ambiente promete insegurança, os países desenvolvidos estão sendo tomados por políticos fascistas, e, aqui, no Brasil, o contrato social está por um fio, ameaçado pela desigualdade e o apartheid social.

A wonderful source for those that want to know questions better: Naive Lie Theory by John Stillwell

(Google excerpts)

This book is a wonderful read and it jumps into quaternions very early on. It really helps one learn about them and other spaces. Is also a remarkably Easy to access book on Lie Theory — (basic calculus, linear algebra only real read. Having seen group theory before is nice, but not necessary)

I’m about half way through and just love it.

Also, somewhat related, Visual Complex Analysis by Tristan Needham is a ridiculously good and powerful book.

(Google excerpts)

Anyone that has to interact with complex numbers should read at least the first two chapters in my opinion.

u/gin_and_clonic · 6 pointsr/AskReddit

tl;dr: you need to learn proofs to read most math books, but if nothing else there's a book at the bottom of this post that you can probably dive into with nothing beyond basic calculus skills.

Are you proficient in reading and writing proofs?

If you aren't, this is the single biggest skill that you need to learn (and, strangely, a skill that gets almost no attention in school unless you seek it out as an undergraduate). There are books devoted to developing this skill—How to Prove It is one.

After you've learned about proof (or while you're still learning about it), you can cut your teeth on some basic real analysis. Basic Elements of Real Analysis by Protter is a book that I'm familiar with, but there are tons of others. Ask around.

You don't have to start with analysis; you could start with algebra (Algebra and Geometry by Beardon is a nice little book I stumbled upon) or discrete (sorry, don't know any books to recommend), or something else. Topology probably requires at least a little familiarity with analysis, though.

The other thing to realize is that math books at upper-level undergraduate and beyond are usually terse and leave a lot to the reader (Rudin is famous for this). You should expect to have to sit down with pencil and paper and fill in gaps in explanations and proofs in order to keep up. This is in contrast to high-school/freshman/sophomore-style books like Stewart's Calculus where everything is spelled out on glossy pages with color pictures (and where proofs are mostly absent).

And just because: Visual Complex Analysis is a really great book. Complex numbers, functions and calculus with complex numbers, connections to geometry, non-Euclidean geometry, and more. Lots of explanation, and you don't really need to know how to do proofs.

I minored in technical communication, and the books we used in the writing-oriented classes were Technical Report Writing Today, Handbook of Technical Writing, and Elements of Style (Strunk and White).

Of these, the handbook and Elements are more rule-oriented and don't really get into the details of putting together a document. I'd recommend something like Technical Report Writing Today, though. It talks about identifying your audience, different styles, visual features, visual aids, presentations, instructions, informal reports, formal reports, feasibility reports, proposals, user manuals. It doesn't get into a whole lot of depth, but it provides enough information to get you started in a whole bunch of areas.

u/AgAero · 6 pointsr/askscience

There are many reasons:

  • Hydrogen is nasty to work with. It's colder than lots of other cryogenic propellants. Its vapor pressure varies so rapidly with temperature that either you perfectly thermally isolate it from its surroundings or the liquid will boil and pressurize the Ullage volume. Either you vent off the excess gaseous hydrogen through a check valve, or you make your tanks stronger(and heavy as fuck). Venting is actually already done with other cryogenic propellants as well, but hydrogen requires doing so very quickly depending on how good your tanks are.

  • The tanks are heavier. Not only because they have to contain more volume, but because they have multiple layers. Vacuum insulation requires you to cover the surface area(plus some change) twice. (Aside: Longer term storage like you might find on the surface of the planet would also likely have a liquid nitrogen or helium layer as well to collect the radiative heat from transferring into the main hydrogen tank. Think: atmosphere/metal/vacuum/nitrogen/vacuum/hydrogen main tank.)

  • Additional turbopumps/inducers required to keep hydrogen from cavitating, increasing the inert mass even further. To keep the turbopump from cavitating, its pressure has to be raised somewhat gradually. If the pumps cavitate not only will performance drop, but the pump will begin to vibrate and possibly induce some unwanted structural dynamics that may break something during launch.

  • And of course, as others have mentioned, hydrogen has a tendency to diffuse into stuff. This makes it brittle and more susceptible to fracture.

    tl;dr: Working with liquid hydrogen is actually pretty awful. (We'd use kerosene if we could find it on Mars, but CH4 is manufacturable in situ.)

    Source: I had to double check lots of this stuff with my copy of Sutton and Biblarz. The inert gas layer thing for the tanks is actually me paraphrasing one of my former professors though; it's not in the book from what I can tell.

It's not synth-specific, but definitely get yourself a copy of Horowitz and Hill's textbook "The Art of Electronics". I've yet to meet a synth-head or electrician lacking one. This'll tell you all about op-amps, fundamental building blocks of filters, oscillators, and other complex elements, and even power electronics if you're interested in power supply design. (No exaggeration, it starts and Ohm's law and ends with complex filters, PLLs, and how to program your new discrete-digital computer in assembly.) Again, not synth-specific, but the book explores how all of these things may be used in application. This'll help you develop intuition to break down complex synth diagrams and how exponential converters work, for example.

Electrosmash has some great analysis articles on some classic pedals. They get into different components and design choices in exacting detail.

But seeing the parts in context will give you an idea what they're doing. A lot of electronics guides focus on on the abstract mathematical relationships between components, which are important but don't give you the "what's this do" information you might be looking for. Practical electronics for inventors is a good book that covers fundamentals with common examples.

You are also going to need a good, cheap source of electronic components. Mouser is what I use.

In short here is your checklist!

  1. Learn to program in C.
  2. Read practical electronics
  3. STUDY MATH (you can't get around it. You need Calculus, Trig, and Differential equations. Wave related subjects are especailly important. For computers throw in algorithms.)

If you're taking lectures and seminars at a university and discussing the subject with other students then a minimal, rigorous and terse textbook maybe just what you need. However, if you're learning math as a hobby in your spare time and on your own, a book that gives copious examples, and motivates the subject from many angles, is much more useful.

For those wondering how you might go about doing this yourself, you have a few choices. Knowing a language useful for modeling can help. Even if it's "just" Python.

NORAD maintains a two-line element set database that is refreshed daily. What is a two-line element set, or TLE? Back in the 1960s, when punch cards were still used as a primary storage device for computational data, a format was needed for easily storing the orbital elements of a space object (typically a satellite, but it can be anything in orbit, for instance rocket booster debris). The orbital elements are mostly the same as what you're used to seeing in KSP, but there are a few additional ones that are required for accurately* computing the propagation of the orbiting object in real life. A TLE looks like this:

COSMOS 2463 [+]
1 36519U 10017A 18293.58648576 .00000043 00000-0 30755-4 0 9996
2 36519 82.9602 143.9870 0035918 330.7244 29.1897 13.71429387424689

The first line contains mostly metadata, the second mostly orbital elements and some additional information you'll need. The TLE's orbital elements are the following:

  • Epoch
  • Inclination
  • Right ascension of the ascending node (also known as longitude of the ascending node)
  • Eccentricity
  • Argument of perigee (also known as argument of periapsis for any orbit, perigee is for Earth)
  • Mean anomaly (fraction of the orbit that has passed since perigee)
  • Mean motion (revolutions per sidereal day)
  • Revolution number at epoch
  • BSTAR drag term

    Now, the first and last two are not technically your classic orbital elements but we need the first to get an idea of when the data is applicable and the last one comes in handy for objects in the LEO which are subject to significant atmospheric drag compared to say, something in a geostat or geosync orbit that is so high up that drag is not as much of a factor.

    Putting these together is the more difficult part. For a classical treatment of the subject, I started with Fundamentals of Astrodynamics by Bate, Mueller and White. This is the older USAF Academy book and is interesting not only because it teaches how to compute a satellite propagation, but it gives you an idea of the strategic position of the USA during the cold war. A significant portion of the book deals with how an ICBM works. Since it is, after all, a space vehicle.

    If you want to get deeper into it, you then want to read something like Vallado's Fundamentals of Astrodynamics and Applications which will get into more detail.

    Robert Braeunig's website gives a good summary of how all of this goes together, with information derived primarily from the first book I linked, although I will caution that the solutions discussed are not all numerically stable in the format in which they appear. There are many, many different ways to compute the solutions to a satellite propagation using the orbital elements.

    If you don't want to spend a few weeks trying to do this yourself (and it will take you that long, unless you're an absolute savant at this), fear not. David Vallado has written code that will do the orbital element calculation along with SGP4 routines for you. What is SGP4? Remember that the Earth is not spherical and there's that other large Moon thing that also orbits the Earth. This means that we can't really model a satellite's orbit like you do in KSP if you want an accurate solution. So, we have to include those perturbations in the final calculuation, which is what the code linked here will do.

    As far as I can tell, the popular website uses a ported version of the above code, available in javascript here. The other link I gave gives versions that will work in FORTRAN, C, C++ and MATLAB (because you just can't make it in modern Engineering if you can't do MATLAB. And you'll have to do MATLAB or you will not make it through the course).

    This should all get you started. I hate to admit it but I never would have taught myself all of this, nor would my personal bookshelves be as heavy as they are, if it weren't for KSP.

  3. There are companies that will do all of this for you. If your idea is fundable, you can probably just hire a firm or in-source to an ECE to do this for you, and may be better than the 10k-ish hours you'll need to get decent at this.
  4. One strategy when pitching to investors is separate "looks like" and "works like" prototypes. You can demonstrate your (physical) vision for the product while still demonstrating that it's actually technically feasible.

  1. Definitely. Personal experience: I have less than a year of industry experience and was offered a position starting at $59K + full benefits + stock options in from a fairly large commercial aeronautics company in TX.

  2. Maybe not those skills specifically, but hiring managers will be very impressed (and maybe intimidated) by "nuclear operator" and military experience in general. I was friends with a nuke guy similar to you who was in my aerospace program and he's miles ahead of me in terms of opportunity.

  3. Nope, as long as you go to a top 50 (hell, even a top 100) institution you'll be fine and won't be at any sort of disadvantage. I know you're riding the GI bill and can probably go to an expensive private institution like Embry-Riddle (barf), but I urge you to instead choose a university that will make you happy as a person, located in a city that has lots of fun stuff to do.
  • NOTE: you might want to investigate whether your choice of university has a good VA program (esp. since it sounds like you were discharged for medical reasons). I was friends with a few Navy guys that developed macular degeneration from working around diesel motors on ships, and the VA office at their university sucked which kind of made everything else suck.

  1. Brush up on algebra, trigonometry, vector calculus, and classical physics, and you should be solid. I recommend purchasing this book as it covers nearly every topic taught in an undergraduate engineering program, plus you can use it to prepare for the FE exam if/when you decide to take it.

  2. The best advice I can give you is to get hands-on experience while attending school. Any respectable astronautics program will certainly have a rocketry, robotics, and/or satellite group, and I strongly encourage you to join at least one of those groups. Learn how to weld, put subsystems together, code, and most importantly learn what it actually means to work in a group of engineers under a deadline.

  1. You get a felt pen and some plastic 'paper' to write on.
  2. I did not feel rushed. Plenty of time to doublecheck my work (at least on the problems I had an idea of how to solve) and finished with about 20mins left.
  3. The material goes deeper than the old paper exams but the problems remain about the same complexity. Most can be solved in 1-2 steps. For example, I had a bunch of questions on radio signal modulation. By looking at the circuit you had to determine what type of modulation was used.
  4. I felt pretty defeated leaving the exam and wouldn't have been surprised if I had failed (I passed). Remember that the electrical FE is the electrical and computer FE. There were more than a couple in depth questions that were way outside my specialization area.
  5. I studied, on average, about 5 hours per week for 8 weeks. I felt prepared going in to the exam.

    Here's a previous comment of mine that I've posted a few times for people with CBT FE questions:

    I took the Electrical/Computer FE in early Feb. I believe the key to studying for the new CBT FE is to use the FE exam specifications for your discipline as a study guide. The focus of the CBT FE is significantly different than the old paper-based FE. In the old version, the morning session was a very broad assessment of the fundamentals of engineering and the afternoon session was dedicated to your discipline. The CBT FE is tailored to your discipline, both the morning and afternoon sections, and goes deeper into your discipline topics than the previous exam. I used the FE Review Manual, which is based on the old exam, for the majority of my studying. The old exam was more breadth than depth, so that book doesn't cover everything that you may encounter. I pulled out my old textbooks to fill in any gaps. Because the CBT FE is still pretty new, I doubt there are any updated review books out there yet.

    NCEES has a series of youtube videos that describe the experience, which is very close to what I saw on exam day. Expect to leave the test feeling like you failed, it's meant to be difficult.

    The 'reusable writing pad' is a little annoying because the pen writes much thicker than a pencil. But other than that, I don't think you'll notice much difference between taking the CBT and any other paper-based exam.

    The reference material is a searchable PDF that displays on half the screen. Download the reference manual from NCEES ahead of time and get familiar with what is and isn't included.

    You'll do the first 55 questions then review and submit them. After you submit them, you won't be able to revisit them again. Then you have the option to take a 25-min lunch break before starting the next 55 questions. I ended with about 20 minutes remaining.

    My basic strategy: Easy questions first, then the ones inside my concentration area, then the ones outside. You'll usually know in the first 30 seconds or so whether you know enough to answer the question (being familiar with what's in the reference manual helps with this).

    There is an option to flag questions for review. But when you get to the end of the section it'll also tell you which questions have not been answered. So don't use it whenever you skip a question. Use it to tell yourself that you're not confident in the answer you've selected so you can return to it if you have time.

    Hope that helps.

u/themeaningofhaste · 5 pointsr/AskAcademia

Griffiths is the go-to for advanced undergraduate level texts, so you might consider his Introduction to Quantum Mechanics and Introduction to Particle Physics. I used Townsend's A Modern Approach to Quantum Mechanics to teach myself and I thought that was a pretty good book.

I'm not sure if you mean special or general relativity. For special, /u/Ragall's suggestion of Taylor is good but is aimed an more of an intermediate undergraduate; still worth checking out I think. I've heard Taylor (different Taylor) and Wheeler's Spacetime Physics is good but I don't know much more about it. For general relativity, I think Hartle's Gravity: An Introduction to Einstein's General Relativity and Carroll's Spacetime and Geometry: An Introduction to General Relativity are what you want to look for. Hartle is slightly lower level but both are close. Carroll is probably better if you want one book and want a bit more of the math.

Online resources are improving, and you might find luck in opencourseware type websites. I'm not too knowledgeable in these, and I think books, while expensive, are a great investment if you are planning to spend a long time in the field.

One note: teaching yourself is great, but a grad program will be concerned if it doesn't show up on a transcript. This being said, the big four in US institutions are Classical Mechanics, E&M, Thermodynamics/Stat Mech, and QM. You should have all four but you can sometimes get away with three. Expectations of other courses vary by school, which is why programs don't always expect things like GR, fluid mechanics, etc.

I hope that helps!

Arduino is a great learning tool and to go from idea to finished project is quite fast. I definitely recommend starting with arduino and see if you like it. If you continue, you'll find that you have to purchase an arduino for each project you start, which can get quite expensive, or you'll be ripping apart old projects to get the arduino.

I purchased arduino and a few shields, but I felt like I really didn't know how everything was working electronically. I really enjoy programming, learning about electronics and making devices, so I decided to stop using arduino and just use the atmega microcontroller, which is the MCU that arduino is based on.

If you wanted to go this route then I would suggest buying an AVR ISP mkii programmer and downloading atmel studio. It's much easier to program the chips than any other method I've tried. Less fiddling. If you have experience in C programming then it will be really easy.

This is the best beginners tutorial I've found for atmel AVR:

David Griffiths' textbooks on E&M and quantum mechanics were easily the best textbooks I had as an undergrad. Clear, concise, refreshingly informal, and even a dash of humor.

I recommend Griffiths' Introduction to Electrodynamics.

You will find it difficult to escape vector calculus in understanding electromagnetics, but Griffiths begins with a quite clear refresher of what you need to know. He continues into electrostatics and magnetostatics, then to electrodynamics, EM waves and radiation, and finishes with relativistic electrodynamics. He also has an informal, conversational style. The text suffers a bit from putting necessary concepts in the exercises, some of which can be quite difficult.

The Amazon reviews will say much more than I have - also look at the reviews for the 3rd edition (which I have, and which has been out for longer).

I highly recommend David Griffith's Introduction to Electrodynamics. It is a classic undergraduate text in electrodynamics.

We could be doing a much better job as a species, but we'll still be OK.

There's a book on global warming, Six degrees. It has six chapters, one for each degree of warming. There's no need for a seventh chapter because there won't be any humans left in that scenario. According to the book, if we exceed +3°C, industrial agriculture will collapse (more or less quickly, depending on the region), and billions will starve.

We're currently on the trajectory for a warming of roughly +3.4°C. I imagine that the despair that comes with the early consequences will push down this path down to something like +2.8°C. Still, the lives of roughly five billion people are very insecure on that path. That's apocaplyptic enough for me.

  • Getting started in electronics

  • Notebook doodle style, super simple. Not only for kids despite the electron smileys showing you how electricity works. Electronics in an intuitive fashion, from winding a coil around a nail to build an electro magnet to simple circuits (and beyond).

    > sensors and motors and stuff

    > laserpointer

    Laser modules cost $0.15 or so at Aliexpress, Servos $1... Everything is so inexpensive it's great to build all sorts of crazy machines ;-)


    > What arduino

    Most guides and books will probably talk about the UNO. You can get a compatible board for around $3, but a Nano also works in the same fashion and sits nicely on a breadboard.

    For the UNO, you have all sorts of modules/shields, but there's nothing you can't hook up to one of the smaller boards.

    Also order an ESP8266 based board, like the $3 Nodemcu or D1 Mini. The ESP8266 has wifi built in and can run stand-alone, as it's a microcontroller with more memory as the UNO/Nano :-) But it's 3.3v, has only one analog input, and it's a bit more work when starting out.


    > What

    You could get a kit if you would like all sorts of sensors and modules.

    The Chinese starter kits are super cheap ($22 with UNO compatible, $26 with MEGA). As Aliexpress links often trigger the spam filter, search for 1207150873 or 32543887265.

    The differences are subtle, some kits lack the ultrasonic sensor (<=$1), etc.

    What's also a LOT of fun is a 2wd robot car kit, you can get them for $15 or so. Two geared motors, dual H-Bridge, put an Arduino + Ultrasonic sensor on it, and with ten lines of code, it will be an obstacle avoiding car or line follower ;-)


    These kits usually don't have great instructions. If that's what you want, get the official Arduino starter kit, or something from Sparkfun, Adafruit etc.

    The Arduino site, instructables, and all kind of blogs have examples for almost every module/sensor/device you can find :-) Find a good guide, such as t
    e, and see if that would work for you.


    The only down-side when going with the compatible Arduino boards: You will have to install a different driver manually (oh noes).


    If you don't have one already: A soldering iron.

    I know, when starting, soldering sucks. You want to do everything on a breadboard, reservable. But I found out way too late how great and time saving soldering is once you use a decent soldering iron ;-) Most will recommend something like FX888D or better, but a $15-$20 adjustable soldering station can work as well for the occasional soldering job. And there's a soldering comic :-)


    A multimeter is a must-have as well. $3 ones work for simple resistance and voltage readings. For high voltage / high current tasks, they might burst into flames and double as fire-starter, ideal in the cold winter time.

    Part testers for $15 can be neat, they identify parts (is this a NPN or PNP transistor... or something else?).

    Cheap regulated $20 power supplies can be nice as well.


    Edit: Bunch of capacitors, resistors, transistors (Bags of 100-500 for $1-$2 via ebay), and whatever sensors you need ;-)


    Sorry for the long post :-) It's always difficult to tell how much experience and equipment someone already has.

I threw myself in at the deep end. The first thing I built was a basic 4 bit CPU out of TTL logic. Took 4 years to get it working in 1983. No regrets doing it. Looks like you've picked an interesting project though.

This is a good book that covers just about everything you need to know including theory, construction, part selection etc. I'd give that a good read or at least scan the relevant sections before jumping in. Expect to spend a month or so on it (no joke - this is a big subject!) It's pretty cheap for the size of it (8x10" and about 2.5" thick) and the information is really nice. There are some math heavy bits but you can work through these easily enough. Some people will recommend The Art of Electronics but controversially I'm not much of a fan.

Breadboards are dicks as a rule. Some of the time they're ok, some of the time they're not. They have various side effects on some classes of circuits and some higher frequencies. If you're going to buy one I'd buy a good one. 3M make the best ones but they're damn expensive. Wisher make the next best ones. The rest are pretty crap to be honest and are probably a liability. If you're doing high frequency stuff i.e. RF or anything, sometimes it's just better to solder the stuff "dead bug" style mid-air over a PCB blank when prototyping.

Any questions, just ask :)

This book is Amazing, and works hard to get the reader to understand many of the many technologies that make our world function, and has guides on how to short-cut our way through technologies to be able to use the most impressive tools we have now.

There is some amazing stuff in here, like how to build a wood gassifying engine to run motors, and other really great stuff. Plus, if people look at you funny, you can just tell them you're just reading it for the science or whatever.

u/NotAlwaysSarcastic · 3 pointsr/PostCollapse

"The Knowledge: How to Rebuild the Civilization in the Aftermath of the Cataclysm" explains most of that, and then some. You can buy it in Amazon:

Pick up the book Visual Complex Analysis by Tristan Needham. You can probably find a free copy online, but this one is, I assure you, worth every penny. Not only is it the most intuitive book on complex analysis ever written in my opinion; it is probably among the very best mathematical books in general.

Let me put it this way. I happened upon that book in high school and was so captivated that I read it cover to cover. Upon entering college, my understanding of the subject was so strong and intuitive I could jump into graduate-level complex analysis with little to no difficulty.

u/acetv · 3 pointsr/math

Complex analysis, my friend. If you can understand even the basics intuitively it can smooth out a lot of the higher classes. I like Needham's Visual Complex Analysis but I've been told it's not a good introduction. I'm not really sure what would be, but you might want to look at Introductory Complex Analysis by Silverman (Dover books are cheap and awesome).

Graph theory certainly wouldn't be too bad either. It's actually pretty fun and has applications in programming and algorithms. Dover publishes this book which I expect would be excellent to read at work (pretty basic, moves slowly). Same goes for linear algebra if you can find a book on it (look for one with "matrix analysis" in the title).

Learning advanced set theory or category theory will probably not be useful at all. (*ducks*).

u/Banach-Tarski · 3 pointsr/math

Neither of those is the complex plane. The first is 3-dimensional in the real manifold sense and the latter is 4-dimensional.

It seems that you are confused about what the complex plane is, so I would suggest that you read Needham's Visual Complex Analysis. It's a very gentle introduction to complex analysis that also conveys very good visual intuition for what is going on.

u/mantrap2 · 3 pointsr/ECE

A linear time-invariant circuit system is a linear system. You can represent it as a linear matrix - which is what SPICE does to solve circuits: V = Z I or I = Z^(-1) V.

An affine transform is merely a form of linear matrix transformation that has particular constraints on its elements that cause it to be "affine". Without more information this makes no sense to do on a circuit but maybe there's a case I don't know about.

There are issues with general circuit representation in this form so systems like SPICE do NOT use these in this form but in a combined matrix form (so you can have zero or infinite values of V or I or Z without blowing things up).

A really, really amazing book on linear transformations and how they tie to complex math is Tristan Needham's Visual Complex Analysis.

If you've ever been fascinated by circuit theory with regards to linear algebra, Fourier transforms, Euler's Identity, Stability Analysis, etc., and wanted to understand the underlying math better, this is the book to read. It's easy to read but has plenty of rigor. Also highly relevant to graphics transformations used in GPUs.

u/redditor62 · 3 pointsr/math

Saff and Snider is great for applied complex analysis. In my opinion it strikes a perfect balance between accessibility and rigor for a first course on the subject.

Visual Complex Analysis is another good choice, but it might be a little more advanced than what you're interested in.

The first half of Lang might also be a good choice, but Lang takes a slightly more formal, proof-based approach.

I've also skimmed through Brown and Churchill, which looks quite good but is prohibitively expensive.

Finally, you can find many cheap (~$10) books on the subject by Dover. The only one I've looked at is Knopp, which is quite formal and light on computation, but might be a good supplement. Here's another Dover book with outstanding Amazon reviews.

Complex analysis is both very elegant and very useful. Best of luck with your class!

First, congratulations on having written something. Many of us end up thinking about ideas and never taking the time to get them down. My critique is rather heavy in tone, but I want to be clear: that doesn't mean your piece is without merit. Keep writing.
I think you can safely call the piece fiction.
Your grammar is generally fine. That's based on a quick read-through. Your best friend here is a copy of The Elements of Style.

"An" instead of "a" in the last sentence, paragraph six. That sentence is also a rather long, clunky fragment. I don't mind fragments, especially if they have a certain punch to them. This fragment does not. Avoid it and others like it.
The only other grammatical change I'd recommend is in paragraph five: "They would've to do..." While "would" and "have" do combine to make that contraction, it feels out of place with the infinitive "to do." Instead, try, "They'd have to do..."

It's difficult to critique something both unfinished and this brief. I will say that the opening is generic and uninteresting. It strikes that unpleasant balance of being unimaginative and over-reaching. Your idea, when you start writing about it, is more engaging. Would you consider shaving the first few paragraphs down to one or two? Alternatively, you could open with a very short (I'm talking 1-2 sentence) exposition on the technology.
I hope that is helpful.

Hey, good luck on this! I made the opposite swap: studied physics as an undergraduate, then studied mathematics in grad school. I'm now a professor in a math department, though I still do some (mildly) physics-related work. Since nobody else has answered yet, I'll say what I can:

  1. You're certainly not too old - there are plenty of stories of people getting started in research at a much later age. The most likely problem is that you'd be graduating around 30-33, then probably moving for a postdoc, then probably moving again... and throughout that, you won't be making tons of money. For some people, that isn't a problem. For many people (including me), that can be a frustrating way to live. Of course, this all depends a huge amount on your partner.

  2. Research is everything! But I think you're really asking two questions: do you need research experience, and do you need physics research experience? For the first, most schools take plenty of people without undergrad research; even at top physics schools, very few people have done meaningful research before. So don't worry too much on that front. Of course, the subject does matter, and this will certainly matter for your application. For some areas of physics, you'll just be a bit behind. For other areas, you'll be a lot behind. Think about that when discussing your research in the application.

  3. This is the standard electrodynamics book:
    The amazon page also suggests a quantum book and a mechanics book; those seem pretty reasonable choices as well. With respect to the math, the background for doing physics research is quite different from what most math majors get. Physicists do a lot of PDEs, ODEs, calculus of variations, and differential geometry. This is pretty serious stuff.

  4. This is a pretty broad subject. What is your math background like? In any case, from a day-to-day perspective, doing mathematical physics often just means doing mathematics...

  5. I have no idea what this means.

  6. Are you in the US? Many schools have undergrad research programs. Many big labs also hire lab techs. This can be a good warmup, but of course requires relevant skills.

  7. Maybe. Chances of getting a faculty job go down with grad school ranking, but they aren't exactly 100% even at e.g. Princeton, and aren't 0 even at the bottom. I'm a pretty cautious person myself, and probably wouldn't have gone to grad school if I knew more about the job market.

  8. Sure. There are practice tests out there; you can see how you're doing. The physics GRE isn't trivial, but it isn't "hard" the same way research is hard. It is just a tricky exam. This is also probably a reasonable way to show people that you've picked up some physics; in that sense it might be more important (and useful) to you than it is to most applicants.
u/1SweetChuck · 3 pointsr/EngineeringPorn

I would say start with Griffiths Electrodynamics, and maybe a calc book, then go from there.

u/sahand_n9 · 3 pointsr/ElectricalEngineering

Griffith's EM book is one the undergrad classics. His book was designed for physics majors mainly but the basics are the same regardless of the major.

u/SuperAstroTornado · 3 pointsr/askscience

If you prefer books, the standard University book on the topic is David J. Griffiths "Introduction to Electrodynamics", which also takes you through vectors and vector calculus. Very readable. As it is probably one of the most widely used books it should be easy to find used for almost no money.

u/gipp · 3 pointsr/askscience

I'm assuming you're looking for things geared toward a layman audience, and not textbooks. Here's a few of my personal favorites:


Cosmos: You probably know what this is. If not, it is at once a history of science, an overview of the major paradigms of scientific investigation (with some considerable detail), and a discussion of the role of science in the development of human society and the role of humanity in the larger cosmos.

Pale Blue Dot: Similar themes, but with a more specifically astronomical focus.


The Greatest Show on Earth: Dawkins steers (mostly) clear of religious talk here, and sticks to what he really does best: lays out the ideas behind evolution in a manner that is easily digestible, but also highly detailed with a plethora of real-world evidence, and convincing to anyone with even a modicum of willingness to listen.


Godel, Escher, Bach: An Eternal Golden Braid: It seems like I find myself recommending this book at least once a month, but it really does deserve it. It not only lays out an excruciatingly complex argument (Godel's Incompleteness Theorem) in as accessible a way as can be imagined, and explores its consequences in mathematics, computer science, and neuroscience, but is also probably the most entertainingly and clearly written work of non-fiction I've ever encountered.


The Feynman Lectures on Physics: It's everything. Probably the most detailed discussion of physics concepts that you'll find on this list.


Connections: Not exactly what you were asking for, but I love it, so you might too. James Burke traces the history of a dozen or so modern inventions, from ancient times all the way up to the present. Focuses on the unpredictability of technological advancement, and how new developments in one area often unlock advancements in a seemingly separate discipline. There is also a documentary series that goes along with it, which I'd probably recommend over the book. James Burke is a tremendously charismatic narrator and it's one of the best few documentary series I've ever watched. It's available semi-officially on Youtube.

u/Robopuppy · 3 pointsr/pics

Try Pale Blue Dot. It's where that quote I posted up above came from. For a non-science person, the writing can be a bit dense at times, but it's workable for the most part. Even if it's still too dense, the book is filled with high-resolution pictures of space, so it's still decent if read as nothing but a picture book.

The Ego Tunnel: The Science of the Mind and the Myth of the Self by Thomas Metzinger

u/facefork · 3 pointsr/videos

There's actually a strain of philosophy of mind and neuroscience dealing with this question right now:

is a good example. While you might feel like "yourself" has a unifying central intelligence, and it is most certainly true from a subjective personal standpoint, analysis of the actual neural substrates and cognitive processes that generate of that sense of selfhood shows that it might actually be a very powerful illusion.

u/tvcgrid · 3 pointsr/TrueDetective

Good summary.

I'd add one more point, related to this quote. I've encountered this in another piece of fiction, and the author actually credited this in part to Metzinger's book called The Ego Tunnel. I'm guessing there's other works that touch on this too. Anyway, the gist is that the conscious self is the content of a model created by our brain—an internal image, but one we cannot experience as an image. Everything we experience is "a virtual self in a virtual reality." But this isn't philosophy not informed by science; Metzinger draws on a whole lot of studies and experiments into human cognition. Worth checking out, although it's a big honking work.

> Lotfi Zadeh in his 1965 paper which I am looking at right now, specifically used the term 'binary fuzzy relations' and not 'boolean logic' to describe the reduction of full fuzzy logic to the two-value case.

Uh huh.

What a reasonable person would get from that is "he must be talking about something else."

What you got from that is "I just looked at one paper with a different title. That must mean you're talking about this other thing and you're wrong!"

Stop being stupid, please. Binary fuzzy relations and boolean fuzzy logic are different things.

This is the part where you pretend that even though you found one paper with a different title and pretended that was evidence I was wrong, now that I've found three other much more modern papers involving that title, suddenly paper titles don't matter.

> to describe the reduction of full fuzzy logic to the two-value case.

That's not what boolean fuzzy logic is, though.

> Since he's the one defining the field

Maybe you didn't know this, but there are a lot of other people working in this field than the one guy you know about, and one paper from 1965 doesn't mean that in the 45 years since, nobody's come up with anything else.

> try not to lecture me about right and wrong.

Tu quoque, clown.

> And binary logic has been a term used in electrical engineering for a very long time for two-state logic.

No, it hasn't. EEs have to implement this difference at the chip level. Basically all CPUs support both bitwise and boolean logic at the instruction level.

You're just making shit up to sound correct. You cannot cite even one EE textbook making this mistake.

Page 61. So sorry. Maybe you can find an EE book making this mistake, since I just showed you arguably the canonical intro to EE text, and gave you the specific page number on which that book says you are not correct?

No, of course not. Because you don't actually own any EE books and don't have any way to check.

For all your talk of lectures about right and wrong, citations are brutal. Try one some time; you might be more effective as a result.

You'll need to know basic analog electronics first, and then apply it to learning about logic gates. Otherwise you'll have trouble understanding things like totem poll versus open collector or open drain, why you need pull-up resistors, why there are limits to fan outs, and why unconnected CMOS inputs can make the chip cook.

The Art of Electronics will cover practically everything you need for your project including analog circuits, digital circuits, logic and even MCU's.

u/infectedketchup · 3 pointsr/audioengineering

Get yourself a minor in mechanical (or possibly even seismic if your school offers it). Opens up anything dealing with transducers or how sound waves behave in a medium within a space.

Maybe pick yourself up a copy of Modern Recording Techniques to get a feel for what's going on hardware wise in the field. If you want to do more with the actual acoustics side of it, then grab Master Handbook of Acoustics. As a former EE major (I split before I graduated), I've also found Practical Electronics for Inventors handy to have around, even if only as a quick reference for things. Even has some theoretical refreshers in there if memory serves me correct.

If you find that you want to get into working with instrument amplification, then I'd recommend picking up Ultimate Bench Warrior since, to my understanding, tube circuits aren't really dealt with at the university level anymore.

Hope at least something in here is helpful.

Hey there! Welcome to the hobby!
For reading, I recommend Practical Electronics for the Inventor. If you're brand new and want something a bit less dense, the Make series is a good place to start.
The box you've got looks a lot like a component kit a friend of mine gave me. He tried the electronics program at ITT before they went under and this is what they gave him. It's got some nice stuff in it and it's great for a beginner.
Now, you want to know what's in there? Google is your best friend. Everything has an identifying code on the side. Punch that into the search bar and 90 percent of the time you'll find everything you need to know about it. It's tedious, but it's the way of things.

I can't give you numbers, although others have made such attempts. There is a book available called Six Degrees that attempts to describe the impacts of climate change over 100 years at different levels (1 degree C change; 2 degree C change; etc.). It has numbers, although I can't suggest how accurate they are (those kinds of numerical forecasting exercises are virtually impossible to do with accuracy in complex systems).

Another pop-science but seemingly sound exploration of likely effects (and current conditions) is Hot, Flat, and Crowded by Friedman. It definitely has a "position," but it is a good qualitative place to start if you want an entryway into global environmental change dynamics.

If you're feeling down about working retail you should read this book. It's about the expected results of each degree of climate warming. It's 10 years old. The changes predicted here are actually mild compared to the changes we've seen, suggesting that we may be on track for a 4° warmer world (mass extinction, complete desertion of the mid-latitudes, the amazon first burning then drying to a desert, human fight toward the poles, endemic drought throughout asia, most crop-land blowing away as dust).

Some scientists say it should be even lower, but that's what most of the negotiations are assuming. 3-4 degrees Celsius is likely what's going to happen unless we make some real aggressive moves soon, which will most likely exacerbate some of the things we see already, which are sea level rises, ocean acidification (leading to fish extinctions), melting of the ice caps and glaciers, and weather changes (drought, desertification, melting tundra). 6 degrees is where most people think we're headed if we can't get our act together and there are a whole bunch of hypotheses about what may happen then: . Of course, then there's always the risk of runaway climate change, where we reach a point where warming begets more warming: and we eventually end up like Venus, although that particular outcome is still up for debate.

So to your point, is this all a futile exercise? I'm not sure we can hit 2 degrees, honestly, at this point. But if we hit 3, the earth our grand children (speaking as someone without kids yet) will live most of their lives in will most likely be similar to the one we live in and the one our parents live in. If we let it get to 5 or 6, then all bets are off. You might be right that they'll come up with some kind of Manhattan project to solve it, but there's no guarantee.

The FE review might not be a bad place to hit everything.

Chemical Discipline-Specific Review for the FE/EIT Exam, 2nd Ed

FE Review Manual: Rapid Preparation for the Fundamentals of Engineering Exam, 3rd Ed

u/withfries · 3 pointsr/engineering

Wow, I'm seeing a lot of "I studied the reference manual the night before" comments. I think I may be the only one who studied for the damn thing!

I'd say go ahead and study still. You are paying $100 and will commit a day to an 8 hr test, and you do not want to go through that process more than once. I'll go ahead an assume you are civil, where pass rate is 72% overall and 68% for those that choose the other section. You don't want to be the 30% that has to take it again.

You may have heard this already, but what you'll need three things:

$76 The FE Review Manual. This is the review text nearly everyone uses to study for the test. It covers every subject, works out the problems, and has a practice exam. I'd strategize by looking through the book and working on what you feel you are weak in.

$24 NCEES FE Reference Manual or free download here. This is a the book they will provide you during the test. It has many formulas. It's important that you study with this beside you so you are familiar with the layout and organization of the book. You'll be flipping through it during that test. Now, I noticed that this book really has everything you need, and can even deduce a few things without having studied.

$14-$25 Calculator of your choice, it's restricted so here's a list . I used the Ti-36X Pro because I am more familiar with Ti's and the learning curve was better. Study with the calculator beside you and only the calculator you will take with you to the exam. How to do inverse sin? How to do matrices (oh yeah, these calculators will find determinate, solve systems, and so many other things for you, you just have to find out how).

Apart from that, find videos on youtube for topics you are having difficulty in.

There you have it, my two cents. You will hear often that it is an easy test, but I've heard that from people that have failed the test too (Yeah, trust me I question their train of thought). You are taking an admirable initiative in choosing to study for this test. Good luck and best wishes!

u/welmoe · 3 pointsr/engineering

I took and passed the FE exam this past April. Honestly the best way to prepare for the exam is to a.) be familiar with the reference handbook and b.) review most (not necessarily all) the subjects on the exam by doing practice questions from the FE Review Manual (it's the one everyone uses.)

I studied for a solid 3 weeks reading the review manual and had the reference manual by my side. It helps to know how the reference handbook is organized so that when you take the actual exam you don't have to keep flipping to the index.

Oh and get a TI36X PRO. It can solve derivatives, integrals, matrices, and a crapload of other things.

TL:DR Study the FE Review Manual by Lindeburg, know the reference handbook like the back of your hand, learn how to use your calculator.

u/monetaryelm · 3 pointsr/engineering

This is the study guide I used. It's pretty good.

One other piece of advice though, study what you know. Most of the material on the test is stuff that you should already know. Don't focus on learning new material. Your time is better spent on reviewing material that you might be rusty on to prevent mistakes on the test.

Griffiths' particle physics book is a great intro imo and one of the few (possibly the only one?) that approaches the subject without requiring qft as a prerequisite.

u/Kevin_Raven · 3 pointsr/science

My number 1 recommended reading is Griffith's introduction to particle physics. If you have done undergraduate level physics, you'll be familiar with his E&M and quantum mechanics textbooks, which are well known for being relatively painless introductions to these two subjects. The book is written at such a level so that you could start understanding particle physics with only basic physics knowledge (although knowing some qualitative facts about quantum mechanics may help).

u/conquerer7 · 3 pointsr/Physics

Try learning calculus-based intro physics here. If you're feeling ambitious you probably can jump into the relativity course there, which will have a few things related to particle physics. To keep yourself motivated you might want to read the first three chapters of Griffiths particle physics.

u/diazona · 3 pointsr/AskScienceDiscussion

Hm... I would have to say Griffiths' particle physics book and Halzen and Martin begin to cover the transition between undergrad-level knowledge and the general area I work in. Although for what I actually work on, I don't know if there are any textbooks. It's a pretty niche field.

u/k-selectride · 3 pointsr/Physics

I don't know of any decent online particle physics resources. But there are two good books at the undergraduate level I can think of Griffiths and Halzen and Martin

For superconductivity you want to learn many body quantum mechanics, ie non-relativistic quantum field theory. The most common recommendation is Fetter and Walecka, but I might consider Thouless to be superior on account of it being 1/3rd the length and probably only covers core topics. If you feel like dropping a lot of money, Mahan is very good, but also somewhat exhaustive. Might be worth having as a reference depending on how serious you get. I would get F&W and Thouless simply on account of how cheap they are.

u/bkdrummer · 2 pointsr/electronics

This is pretty great, especially for the price. It is sectioned off into multiple topics, but refers to the other sections as far as design is concerned. It does have some basics, but gets pretty complicated in some of the opamp sections.

I would do it, but with family obligations, I just don't have the time.

There are plenty of good tutorials on how to solder on YouTube. The gist of it is to heat up the components with the iron, then add solder. It just takes practice. And don't buy the cheap solder -- you'll get poor results even with the proper technique.

As far as electronics theory, I like this book as a basic reference.

I remember doing 2 years of almost solid maths, thermodynamics and fluid dynamics, solids, materials etc. It was so uninspiring that I started teaching myself programming (C++) and playing around with 3d graphics (ah, good old days when Quake was the shit!)
I got good grades, but I was not a model student. So, although my 3rd and 4th year focused on 'mechatronic' subjects, I graduated not really knowing what a transistor was or how to solder anything. I was a decent programmer though.

Luckily, I got a job with a really patient, knowledgeable guy who helped me fill in the gaps. I coded stuff, but he explained how the hardware worked, I sometimes understood (or pretended, and when I couldn't figure it out later we went over it again).

I highly recommend this book:

So here's what worked for me: (eventually :) )

  • Get a practical grasp of basic electronics. Thevenin and Kirchoff and all that are important, but ...
  • No matter how good the book/teacher, the best way to learn something is to actually DO IT.
  • Learn C or C++

    So, as far as practical stuff goes:

    Start basic.

  • Get a LED. Turn it on or off with a switch. Make it brighter. Make it dimmer.
  • Use a transistor/FET in the switching circuit.
  • Use a GPIO / micro controller to turn it off and on.
  • Make it turn on for 1 second, off for 1 second. Repeatedly.
  • Make the duty cycle dependent on a trimpot / variable resistor

    Get More Practical:

  • Get an old printer.
  • Take the stepper motor out of it. (Don't throw anything else away yet)
  • Make a circuit to drive the motor from GPIO/ microcontroller
  • Figure out how to make the motor turn. Both ways.

  • Make an assembly where the motor drives a "crane arm". You can make it a rotating crane or a linear crane arm (eg, like how the printer heads move). You may need a gearbox.

  • Hang a small weight (load) on the crane.

  • Figure out how to make the crane move from/to a certain position. With minimal load movement.
  • Figure out how to move the crane from/to ANY position with minimal load movement.

    Old computer power supplies are great if you are on a budget.

If you want to learn about electronics, I'd suggest reading "Practical Electronics for Inventors" by Paul Scherz. Truly an excellent book. You can get nearly as much out of this as you would a four-year electrical engineering schooling, but it's written so that it's totally accessible if you don't want to go that far in depth.

u/anbolkonsky · 2 pointsr/AskElectronics

+1 for recommending Practical Electronics for Inventors. I highly, highly, highly recommend this book. I am currently an electrical engineering grad student and I still reference this book from time to time when working through simple circuits, either for debugging or optimization.

u/Beegram2 · 2 pointsr/AskElectronics

It's difficult to tell without seeing it, but "Learning the Art of Electronics" looks like a book to accompany "The Art of Electronics". If you're a beginner, The Art of Electronics might be a bit overwhelming. My recommendation as an absolute starting point is Getting Started in Electronics by Forest M. Mimms. It's old and used to be sold at Tandy, but it gives a really quick and simply overview of the basics, and you can get the 3rd edition here for free:

If you're still interested after reading Getting Started, it's probably appropriate to move on to either The Art of Electronics

or the much cheaper Practical Electronics for Inventors (as mentioned elsewhere - 4th edition is out in April)

u/Shadow703793 · 2 pointsr/arduino

I can recommend you a few things, speaking as a CS/EE double major :)

  • Hands on skills are quite important. Learn how to solder, use a DMM, strip wires, etc. There's a lot of tutorials on Youtube and such that show you how to solder well,etc. Watch them and practice.

  • If you're still in school, you may want to consider taking a intro EE course as an elective or similar. If you're not in school but have the time and money, you may want to consider taking a few classes at a nearby college (ie. community college). Alternatively, get a few books/online tutorials and such and self study. I believe MIT OCW has a quite a few EE courses available.

  • Books wise, i recommend the following: Beginning Arduino, Practical Electronics for Inventors, Arduino Cookbook (excellent refference book). Website wise, I recommend t ro n i x s t u f f.

  • Start with the basics. This includes both theory (understanding and applying Ohm's Law) and practice (building actual circuits). Play with the Arduino and LEDs, motors, servo, ultrasonic sensors, etc. Follow tutorials for these BUT know WHY certain things are done in a given way and the reason those things are done. For example, understand why you need a resistor(s) when using LEDs.

  • Once you have the basics down (ie. how to hook up and drive a motor), start a small project. I personally recommend something like an obstacle avoiding or line following robot as it's quite cheap, lots of online help available, easy to understand, etc. Read my post here for more details.

  • Equipment wise, you'll need a few things. Take a look here: You don't need everything on that list, but get the basics like resistors, capacitors, wires, general purpose PNP/NPN MOSFETs, etc. Then get a few sensors (ie. ultrasonic sensors, photo detectors, temperature sensor, etc) and a few other useful things like shift registers, LCD, piezo buzzer, etc. Also, check out this from /r/electronics.

I my self am a CS student, I design my own custom board using Cadsoft Eagle, etch it, solder it and so on...

Nothing is hard, you just need to practice. Just search a bit online and start with the easy and small tutorials.

Edit: Grab your self an Arduino Kit or buy a bunch of each component (Jameco, Digikey, Mouser,,, Sparkfun....) and the required tools (soldering iron, plier, breadboards.....)
Also, you can buy some unsoldered boards with their components and read the manual to learn more about circuits and soldering.

The big one was Shigley's Mechanical Engineering Design. All the NCEES test development is done at Clemson and living in SC, a lot of those professors teach prep classes. This one was recommended far and above any other textbook for Machine Design stuff.

I think, in total, I brought in the MERM (heavily marked and noted), the MERM problem guide, the two practice exams, the Machinery's Handbook, Shigley's book, the conversion guide, a couple of the guides given to me at the prep classes (which were mostly focused on HVAC and fluids as my weak points).

The most use came out of the MERM obviously, but there were some questions on the tests that were verbatim out of the problem sets. It was all the right amount of stuff to bring without getting too bogged down in the materials (like the CEs I saw that brought in rolling carts worth of materials).

I think that Griffiths has a pretty good explanation of all that (although it's a electromagnetism book). You can look up the chapter 12.

Do you know what textbooks you'll be needing next year? It might be a good idea to get a hold of them early and familiarize yourself with the material.

The go to undergraduate E&M book is Griffith's, Introduction to Electrodynamics. E&M is tough for a lot of people, so it'd be nice to have a leg up by reading through some of this book before the semester starts. Griffith's writing style is really easy to follow and he tries to guide you threw important derivations without skipping around too much. There's a reason this book is so ubiquitous in undergraduate physics.

Griffiths Electrodynamics would be a good thing to look at. It's surprisingly readable, and it could possibly wind up being your E&M textbook. In my undergrad, E&M was the "weed out" course, where those who weren't up to scratch lost interest in the physics degree, so it's good to get a head start. I wish I had started on it sooner. Maybe I'd have gotten more out of E&M as an undergrad and then Jackson in grad school wouldn't have been so hard.

You might like this book by Coxeter, who also co-wrote Geometry Revisited. Tristan Needham covers a bit of non-Euclidean geometry in Visual Complex Analysis.

u/po2gdHaeKaYk · 2 pointsr/funny

Part of the problem is that there are a lot of little things that are subtly wrong, and I'm sorry if this sounds patronizing, but it's because you're still ignorant of the larger theory. Let's take a few statements.

> Trigonometry is not the same as geometry by any means,

Trigonometry is the branch of mathematics that studies relationships between lengths and triangles. If it is not geometry, I do not know what is.

Now I think that people are being suckered into these statements because they associate the manipulation of sin/cos/tan as functional quantities. So they start thinking that this is not geometry because it involves purely algebraic manipulation of functions. Which is absurd. What do you think the graph of sin/cos/tan comes from?

It reminds me of a student who once had to punch into her calculator the value of sin(0). If you understand the origin of the definition of sine, you understand its value at the origin.

> especially the trigonometry used in electrical engineering (where it's really about complex exponentials, eiθ = cosθ + isinθ).

The notion of a complex exponential (typically) requires the notion of geometry in the complex plane. I say (typically) because there are different ways of defining the complex function. For example, you can define it as the addition of two separate infinite series that make up the real and imaginary parts. However you define it, you won't escape the notion that it is linked to points on the unit circle. This is geometry.

Tristan Needham basically claims (around Chapter 1) that the importance of complex numbers in many scientific pursuits is based on the fact that it is effectively equivalent to the definition of Euclidean Geometry. Hence again geometry.

> Electrical engineers aren't using trig to represent geometry, but to represent oscillations

Again, where are these oscillations coming from? They are defined via ratios of side lengths in a triangle as a point is rotated around the unit circle. This is geometry.

> Also, they're used in Fourier transforms and series - also completely unrelated to geometry.

A Fourier series is defined via an expansion of certain functions into more basic components of sines and cosines. The reason why you are able to do this boils down to geometric extensions of the notion of orthogonality and projections. Basically, the individual modes are orthogonal to each other (except their twin), and by projecting things in a judicious manner, you can derive formulae on the Fourier coefficients. Projections and orthogonality...this is geometry. What functions can or can't be Fourier summed? This relates to notions of continuity, differentiability, integrality, and periodicity. All of these, in the case of Fourier Series, are intimately linked to circles and ratios of side lengths.

As I pointed out in another post, the definition of Fourier transform inversion requires contour integration in the complex plane. Where do you think all those tables Engineers use are taken from? Contour integration is geometry. It involves notions of decomposing line segments and curves into sub-elements, integrating over circles and arcs, etc. Hell, even integration is geometry. If you can't figure out what area means, then how do you define the concept of an integral?

The problem is that students lose this geometric understanding of mathematics. Then you have to explain to them what happens when you actually integrate, or why an integral they calculated is obviously positive or negative based on the parity or sign of the function.

u/yourdadsbff · 2 pointsr/mildlyinteresting

Well, every grammar rule is technically "made up" and subject to (sometimes glacial) change. Besides, if grammar has its rules, then style has its elements that can often be as important as "legal" ones. This is true not just in grammar but also in life; for instance, wearing sweatpants to a job interview is almost certainly a bad idea that will leave a poor impression on the person who interviewed you, though there's probably no formal rule against doing so. It's a style choice, but an important one. Therefore, we teach many of these style choices as veritable rules, seeing as how instances requiring adherence to formal rules of grammar are often some of the most important (e.g. term papers, cover letters, official report drafts).

So while using fewer as opposed to less in this instance may not be following an iron-clad grammatical rule, in my experience the distinction becomes a self-evident stylistic choice in actual cases of ambiguity.

When the meaning of a given phrase is not ambiguous, such as "Ten items or less," then yes, I'd say it's nit-picky to offer such a "correction." But take Zequi's sentence above:

>Lately, I find less and less people correcting my grammar

I think most of us get the gist of it. Still, I spy a bit of ambiguity. Does "less and less" refer to the number of people correcting Zequi's grammar or to the number of (noticeable) grammar errors he makes at all? The distinction may be slight, but it's still a distinction.

TL;DR I need a life.

u/Excalibur42 · 2 pointsr/Physics

1st year super keen physics student here. I'm particularly passionate about plasma physics and I'm doing a research project this semester as well as an extension to my physics course in that field. I've already ordered a copy of Chen's 3rd edition, and have a hard copy of Fusion Physics as well as a library copy of Griffith's Electromagnetism (only 2nd edition though; worth getting the new one?)

Anyone have suggestions for texts/resources for physics along the same lines?


u/mrcmnstr · 2 pointsr/Physics

I thought of some books suggestions. If you're going all in, go to the library and find a book on vector calculus. You're going to need it if you don't already know spherical coordinates, divergence, gradient, and curl. Try this one if your library has it. Lots of good books on this though. Just look for vector calculus.

Griffiths has a good intro to E&M. I'm sure you can find an old copy on a bookshelf. Doesn't need to be the new one.

Shankar has a quantum book written for an upper level undergrad. The first chapter does an excellent job explaining the basic math behind quantum mechanics .

If you want to google more, your keywords are "hertzian dipole field solution"

The gist of it is that for an oscillating current I(r), you immediatley know the auxiliary fields A and Phi (they follow the wave equation, with I as the source). From the auxilliary fields, you can immediately know E and H. (This is on Pg 8 of that second link). Actually just follow through those slides, you'll notice how the near-field terms you circled in red pops out from the equations.

Totally get it. I have had these moments myself. The world IS huge but more important, we are tiny. Very very tiny. Read Pale Blue Dot by Carl Sagan. If you think you’re tiny compared to the Pacific, just imagine how tiny we are compared to the rest of our galaxy... or our universe!

Once we come to acceptance of our existence, we can come back down and live our life with a purpose to love and help each other. Think about how insignificant every war ever fought on earth is to the rest of the universe. But if we can help make each other’s lives better, that’s pretty cool.

The Case for God and The Bible: A Biography by Karen Armstrong are both good. The God Delusion is a simple breakdown and explanation of most major religious claims. Beyond Religion: Ethics for a Whole World by the Dalai Llama is an interesting book on ethics. The Koran: A Very Short Introduction by Michael Cook is 150 funny and insightful pages on Islam. Under the Banner of Heaven is a shocking and fascinating account of fundamentalist Mormonism. The Demon Haunted World by Carl Sagan discusses religion, and Cosmos and Pale Blue Dot are my secular versions of holy books. And of course given the occasion, I can't leave out God is Not Great.

I recommend avoiding authors like Lee Strobel and Deepak Chopra. Both are essentially liars for their causes, either inventing evidence, or deliberately being incredibly misleading in how they use terms. Popularity in those cases definitely doesn't indicate quality.

u/wolfie12345 · 2 pointsr/philosophy

We. Me. I.

What is an I? Where is the "thing" that is the stuff of a separate entity somewhere under your skin, behind your eyes?

The reality is that there is no center to one's experience. No separate long-lasting "me" that experiences. Only experience itself. The ego arises out of thought, and a "me" is just a concept that the thinking mind conjures up. No agent means no agency. No chooser.

While on first glance this may sounds either incredibly stupid, confusing or woo-woo. But take a look and see.

I suggest you check out this video by Sam Harris that explores the concept of "illusion of self."

Or a book by Bruce Hood that scientifically explains this illusion:

Or others:

Once you break the spell of "self-identity", unity arises.

u/mhornberger · 2 pointsr/DebateAnAtheist

> Or are you saying that it must be the case that anything which can do these tasks must have a first person experience?

Closer to this, but I'm not saying that it would have to be to the level of an "experience," much less that it would necessarily entail the capacity to reflect on it or slice and dice its meaning. Even a Roomba needs some sense or internal modeling of a first-person perspective, emphasis on "some." The unit has to know where it is in relation to a ledge, for example. But even at this rudimentary level there is still the kernel of a self, because something has to be differentiated from the other somethings around which the first something must navigate.

> But why not 'we'?

Because it doesn't mean the same thing. If I lock you in a cell and don't bring you food, you'll starve. "We" (the royal we) could be well-fed and comfortable, but one of us will starve to death. This doesn't hinge on verbiage. You can use other labels if you like, but the underlying facts remain the same. A sandwich being eaten and you getting to eat the sandwich are not the same things. Only one nourishes you.

>Or perhaps there are many different experiences occuring that provide a perception as if there is one entity doing all of it and experiencing all of it.

Perhaps I'm just a Boltzmann brain and I'm imagining all of this. Perhaps this, perhaps that. I focus on how I and others actually engage the world. There is a vast sea of possibilities that we can't prove false. But I want to know how people actually think the world is, and why they think so.

>It's not clear to me what you mean when you refer to yourself.

When you cross the road, do you take care to avoid getting hit by cars? Do you pause in the middle of a busy street to parse what the "I" is you're trying to preserve from being hit by a car?

If you call the police and say someone is trying to kill you, would it make sense for them to say that it's not clear to them what you mean when you refer to yourself? I'm not asking merely if it would be appropriate in that emergency situation, rather I'm saying it would look like a silly and facile question. The question does not seem deep to me. Are you arguing for something, or trying to coax me towards an idea?

Sure, our sense of self can be looked at more closely. I particularly enjoyed Metzinger's The Ego Tunnel, and I've read a number of other books on the neuroscience underlying our sense of self. And there are indeed interesting philosophical conundrums, like the teletransportation problem for one example. But in everyday life we know what "I" and "you" mean. When we ask the waiter to bring us a salad, they know to whom we're referring. I'm using these terms in that colloquial, dictionary sense.

While the above is nice, if you are at all interested in rockets, get Rocket Propulsion Elements. Read it and love it, it is pretty much the bible of rocket engines and serves as a good foundation

u/Lars0 · 2 pointsr/AskEngineers

It's a big topic, and rocket engineering can't be summed in a reddit post. Buy yourself some books.

If you want more knowledge on the design and analysis of rockets, get a copy of Rocket Propulsion Elements By Sutton. ( - You don't have to buy the newest edition, thermodynamics hasn't changed.

I believe for vehicle design the best reference is SPAD (Space Propulsion Analysis and Design) ( - Wow, that's more expensive than I thought.

Both books are intended for upper level college courses so you will need to learn other stuff too - like thermodynamics. But if you are interested in the subject then It will keep you motivated to learn the prerequisites as you go.

To start, learn the rocket equation, if you don't know it already. It is easy to do your first order analysis with just that, and add ~1km/s for air + gravity drag. Also, Wikipedia has an astounding amount of information. /u/danielravennest Wrote this wikibook, I haven't read it myself but he is always raving about it so you might find it useful.

The list provided by david is good, and I'm just going to point out two that are really good for understanding rockets and spaceflight:

Fundamentals of Astrodynamics (ISBN-13: 978-0-486-60061-1) seems to cover the basics.

u/mryall · 2 pointsr/KerbalSpaceProgram

It's all calculable, but quicks starts needing a lot of math once you include orbit changes and air resistance.

An easy start is to determine your desired orbit's dV requirements, then plug your engine's Isp into the rocket equation to determine its propellant-mass fraction. Then you can use the weight of the engine plus fuel tanks and payload to estimate the fuel required to reach orbit in an ideal rocket.

There are quite a few online calculators like this one, that give you a sense of what order to calculate things and the terms to look for in equations.

If you're really interested in deeply understanding the maths behind launches and orbital mechanics, I can recommend this book which is a commonly used aerospace engineering text: Fundamentals of Astrodynamics.

u/SungrazerComets · 2 pointsr/askastronomy
u/Koooooj · 2 pointsr/KerbalSpaceProgram

I'm a fan of my old copy of Fundamentals of Astrodynamics, by Bate, Mueller, and White. It was, by far, the cheapest textbook I purchased for my Aerospace degree (~$7; Amazon has it for <$3 used) but it is one of the primary texts in the field--most other texts wind up referencing this 1970s book. I seldom reference it anymore, though. FoA primarily focuses on how to calculate the motion of a spacecraft. It covers the Patched conics approach, various basic maneuvers, and interplanetary trajectories. It also covers how to figure out the orbit of an object based on ground measurements as well as perturbations--how things like uneven gravity, solar wind, and magnetism can affect an orbiting craft.

I also have read some of the AIAA edition of Space Vehicle Design, but it is considerably more expensive. It goes over more advanced concerns for the design and operation of practical, real-world space craft. If you have the coin and are interested in such things then you could pick it up. I've found the AIAA editions of Aerospace books to be well written in general. That book is only really worth it, though, if you have enough money that you won't miss the $70+ to buy or if you need it for your degree.

I've also had some luck with MIT Open Courseware, but I don't see much on aerospace that would be terribly relevant to KSP.

Sorry that other people are being harsh critics, but yeah man. Respectfully, a couple of these are pretty overpriced.

So for now, I'll answer the question that you have asked, though I doubt you'll like the answer.

This page explains it fairly well, I think. So do Horowitz and Hill, if by chance you have their book handy.

I have used that basic design on a few different occasions, although my triangle wave generator looked more like this one. I believe I used an LM741 for the integrator (that's the amplifier with the capacitor in its feedback loop) and the two halves of an LM393 for the comparator in the triangle wave generator + the comparator used to make the PWM. Those exact parts aren't critical by any means, and I don't see anything wrong with Paul Hills' circuit (the first link) either except the part count is higher.

Edit: If you can find an MC33030, or if you care to trawl through catalogs looking for a modern (i.e. orderable) substitute, it will do do the PWM generation for you and it even includes the H-bridge to drive a motor (or in your case, coil) up to 1 amp.

u/No_Kids_for_Dads · 2 pointsr/DIY

While I understand the desire to make something and see the fruits of your labor, true understanding will come best through reading and research. I mean, you could start making circuits of someone else's design and then play around with the arrangement and values of components, but at best you are really just generating a case-by-case feel of how a particular circuit operates. Doing some calculations with many sets of hypothetical circuits (rather than building a bunch of circuits and playing around and taking measurements) will be a much more efficient way to really get understanding of how these things work.

I would recommend the discrete electronics bible, Horowitz And Hill's The Art of Electronics as well as Malik's Electronic Circuits. (Edit: actually, it's been a while since I've used these books and I can't remember what scope they really cover. I know Malik is a little more advanced and concentrates on state devices like diodes and transistors. Really, a basic engineering circuit analysis textbook might be best)

You should also check out this java applet. It is surprisingly powerful and gives a really good general idea of what electronic components do ('visually' and numerically)

The defacto bible is "The Art of Electronics" by Horowitz and Hill which still sells for $100 even though the latest edition is from 1989. It is a thick book, but is better than most textbooks IMHO. They refer to many part numbers that are long past gone, but it should give you the vocab and keywords for you to search out the current parts.

Other than that, if you want more beginner books - look at Make: Electronics or the Forrest Mims books

If you want to go hardcore into the theory without having to do much math, go for the electronics bible, Horowitz and Hill.

u/MrAureliusR · 2 pointsr/ElectricalEngineering

Okay, you're definitely at the beginning. I'll clarify a few things and then recommend some resources.

  1. Places to buy components: Depending on where you live in the world, the large component suppliers are almost always the way to go, with smaller suppliers like Adafruit/Sparkfun if you need development boards or specialised things. I buy almost exclusively from Digikey -- they have $8 flat shipping to Canada, which typically arrives the next day, with no customs fees. They have some sort of agreement in place where they cover these costs. This *always* saves money over going to my local stores where the prices are inflated. It's crazy how cheap some things are. If I need a few 2.2K 1206 resistors for a project, I just buy a reel of 1000 because they are so cheap.
  2. "Steer a joystick with an app" Do you mean connect motors to it and have them move the joystick for you? You're going to want some sort of microcontroller platform, along with a motor controller and way to communicate with a smartphone app. You mention you know C++ so it will be easy to switch to C. This is both true and false. Programming for microcontrollers is not the same as programming for computers. You are much closer to the hardware, typically manipulating many registers directly instead of abstracting it away. Each microcontroller vendor has their own tools and compilers, although *some* do support GCC or alternatives. You mentioned PIC, which is a line of microcontrollers by a large company called Microchip. There are 8-bit, 16-bit, and 32-bit PICs, all at different price points and with hugely differing capabilities. Selecting the microcontroller for a project can be half the battle sometimes. Or, like me, you can just go with whatever you have on hand (which is usually MSP430s or PIC32MX's)
  3. A lot of people will recommend the book The Art of Electronics. It's decent, but it's not for everyone. Some really like the conversational style, others don't. Many people who want to get into microcontroller programming and embedded development want to skip over the fundamentals and just get something working. For those, I point them to Arduino and let them on their merry way. However, if you actually want to learn something, I highly recommend buying an actual microcontroller development board, learning the fundamentals about electrical circuits, and programming in actual C with actual IDEs.
  4. As far as resources go, again it depends on your actual goal. Whenever I want to learn a new tool (like a PCB layout software, or a new IDE) I always start with a simple project. Having an end point to reach will keep you motivated when things seem complicated. Your controlling a joystick with motors is a great starting point. I would buy a development board, Microchip PICs are popular, as are ST32s, and MSP430. It doesn't really matter that much in the long run. Just don't tie yourself too hard to one brand. Then pick up some stepper motors, and a stepper motor control board (grab one from Sparkfun/Adafruit, etc). Get yourself a breadboard, and some breadboard jumpers, a cheap power supply (there are tons available now for cheap that are pretty decent), and then jump in head first!
  5. I highly recommend the book Making Embedded Systems by Elecia White, once you've covered the basics. It's a great way to learn more about how professionals actually design things. For the basics, you can watch *EARLY* EEVBlog videos (anything past around video 600/650 he gets progressively more annoying and set in his ways, another topic entirely, but the early stuff is decent). I'd also recommend picking up your choice of books about the fundamentals -- Electronics for Dummies, the aforementioned Art of Electronics, Making Embedded Systems, The Art of Designing Embedded Systems, and even stuff like Design Patterns for Embedded Systems in C. Again, it all depends on what your goal is. If you want to do embedded design, then you'll need to focus on that. If you're more into analog circuits, then maybe check out The Art and Science of Analog Circuit Design. Either way, grounding yourself in the fundamentals will help a LOT later on. It will make reading schematics way easier.

    I feel like I've gone off on a few tangents, but just ask for clarification if you want. I'd be happy to point you towards other resources.

They are expensive, but you will learn huge amounts by working through the Learning book. When I was teaching college labs, I would recommend students get these books (2nd ed at the time).

u/HeroOfCanton · 2 pointsr/electronics
u/Saboot · 2 pointsr/Physics

I think it is dependent on the field. For several areas in experimental astronomy you deal with extremely large datasets. Advanced statistical methods and 'machine learning' can be very valuable tools. Whereas for someone studying solid state experiment this would be a waste of time. Better time would be spent on learning the physical hardware and electronics and noise (I think, never done solid state myself). Although you would be surprised, I knew someone who was using neural networks for a project involving solid state and transitions.

As a whole, compared with theorists, you may want to develop a better understanding of statistics, computing/programming, electronics, hardware, and several fields I'm not thinking of. However which of those are most applicable depends on the work you are doing. Although a solid foundation in statistics is most likely useful for all scientists.

To add a text, The Art of Electronics is practically an experimental bible for many people.

u/thach47 · 2 pointsr/Machinists

Any edition would probably work for what you need. The newest looks to be this 29th edition, but I've got an older 24th that I've used in the past. Whatever you can find cheaper and better quality! If you can't find it at the library, i would seriously consider buying your own copy. For me, ever since getting into this trade, i cant seem to find enough time in the day to absorb (and retain!) all the information out there to improve my own ability around the shop!

After reading your description, I finally remembered the black book by that title that people have recommended. Don't have it, but I've got several different machinist's handbooks, such as this one. I collect old editions (50s and 60s), and they all fit into the "handbook drawer" of Kennedy toolboxes.

u/NeoMarxismIsEvil · 2 pointsr/raspberry_pi

The guide is pretty good considering that most of them suck. It contains like 10 small example projects, but won't teach you everything.

This is a good book to get eventually but you don't need it right away: Practical Electronics for Inventors, Fourth Edition Its like a textbook for about $20 except it has a lot more practical how to info.

There are lots of tutorials online about using the RPi and Arduino, especially by Adafruit and sparkfun.

u/PineappleMechanic · 2 pointsr/AskElectronics

As a student, I can recommend "Practical Electronics For Inventors, Fourth Edition" by Paul Scherz, accompanied by the occasional youtube video and reddit question :)
You can buy it from Amazon here

I havent read any others, so I cant compare the quality, but you can go through it like a book and be able to understand everything. You may run into some problems in the real world that requires some fairly advanced calculus, which the book doesn't cover. (It does cover where to apply it, just not how). It is really extensive (1256 pages on my desktop e-reader), so if you have an idea for something specific you want to build, there might be something more efficient out there :)

I would think that not a lot of electronics books, if any, explain the math in full, so I would suggest that you find an online source for whatever specific piece of math you've run into. I can recommend Kahn academy.

Good luck :)

u/social-insecurity · 2 pointsr/chemistry

Good idea. I did an "electronics for scientists" class from the physics department when I was an undergrad. Can't remember what book we used, I think it was by a guy at Duke University maybe. It was a good starting point, covering LRC circuits, transistors, and opamps.

Edit: It's this book:

Horowitz and Hill is a really good reference. I have another book on my reference shelf, I think it's this one:

Here is a great website with some circuits that are common building blocks of instrumentation:

(see "Circuit Collection" link).

Finally, Linear Technologies has a free version of Spice called LTSpice that you can use for circuit simulation on Windows (hope I'm not violating any rules on commercial stuff; I just happen to use it and like it). If you use Linux, there is a package called gEDA that has a schematic entry tool and a version of Spice. I haven't used the Spice tool yet from that package, but it's probably good.

u/ChromaticDragon · 2 pointsr/worldnews

Please pick up and read:

Or watch it. Goodness... they made it into film:

The cool thing about this book is that the focus is on what we can tell happened at these temps at various points in the past. This doesn't give us a clear picture of the future. Indeed, the rate of change today is practically unprecedented. But this look into the past is rather illuminating.

4 degrees is BAD! As others have stated, it's not a simple thing of every part of the world just magically being 4 degrees warmer all the time. It won't be that uniform. There will be parts that get larger average temp increases than others.

There are simply far too many people who think they've stopped being Climate Change Deniers while remaining in incredible ignorance of the related facts. Getting more informed will address the confusion, if not necessarily the fear. I'm not trying to advocate anything here related to vegetarianism, tap water or whatever. It just will be more conducive overall the more people have a better grasp of the issues/data here.

u/DanNeverDie · 2 pointsr/CFB

Rent this book. Then try to do every problem in it. After your soul is crushed by how difficult the problems are and you've given up hope, take the test. You should pass it no problem. Also buy this handbook as it is the only reference material you will be allowed to have for the actual test.

u/TribeCalledMess · 2 pointsr/ChemicalEngineering

I highly recommend this book for prep. I took the FE in October using this as a review and passed, after being out of school a couple of years. This book just covers the morning session. For the afternoon session I would just review your thermo, heat & mass, and design class notes. Also, thinking about buying the equation manual. It was super helpful knowing exactly where equations were while taking that test. They also have topic outlines for the exam on the NCEES webpage. I would also get the practice exam NCEES sells, that was really the only prep I did for the afternoon session. Keep in mind that the test is electronic now, not written, so review materials might vary.

Good luck! I'm sure you'll do great if you are just finishing school, because everything will still be fresh.

u/McMe · 2 pointsr/ECE

I forget the name of the book, but it's yellow. They have a great big one for the general part of the FE and they make smaller ones for the individual tests. I thought those were great study guides. Also, my university had a class to review the major subjects of the FE.

EDIT: General FE [book] (

Electrical Engineering book

u/RoundestBrownAround · 2 pointsr/ChemicalEngineering

This one was for the general stuff (but it still had fluids, heat transfer, econ, and some general thermo) and this one for the chemE. The chemE one I studied might have been an older version though. Both were filled with hard and useful practice problems.

u/Snorey · 2 pointsr/LawSchool

As long as you don't let patent bar and FE prep get in the way of other important things, I don't suppose there's any reason not to do this. Everybody needs a hobby. But you should be aware that the odds of it leading to an actual job as a patent agent are very small.

  1. Probably "Other Disciplines" (formerly known as "General"). But hard to say for sure.

  2. Lindeburg's guide was fantastic, absolutely head and shoulders above everything else -- for the pre-2014 paper-based exam. However, it's probably not very useful any more. I'm not in a position to say what's good, but Lindeburg does have post-2014 subject-specific guides.

  3. Not without something else, e.g. exceptional networking ability or an existing connection. If you look at patent job boards, you'll see that the entry-level jobs you might occasionally see are exclusively for someone with a specific technical background. Even people who have technical backgrounds outside EE often have a very hard time finding patent work.

  4. I don't think so. (But if you were, hypothetically, to take the Mechanical Engineering FE and then try to hold yourself out as having a "mechanical engineering background" or some such, obviously that would not end well.)
u/jojoyohan · 2 pointsr/engineering

The FE changed about a year ago to be a computer based test. It is only 6 hours long and there is no longer a general portion and discipline specific portion. The questions are entirely based on the discipline you select. I've been using the FERM to study and it seems ok. The author has been putting out disciple specific books just for the new test as he gets around to them. I'd suggest you spend the $160 to get the one for the test you are going to take. They do include chapters on things that the general book does not cover.

I'd also suggest not signing up for the test until you are about a month out from wanting to take it. People seem to reschedule their tests and as long as your schedule is a bit flexible, you can sign up relatively close to the test.

u/khartster · 2 pointsr/ECE

I had purchased this book to brush up on the general stuff since EE/CompE wasn't as versed in the general mechanics stuff. I liked it and passed. The Computer stuff seemed trivial in 2011.

I can see if I still have it but I remember selling a bunch of stuff to half priced books a few years ago.

edit: Found it!
Seems like most of it is pseudo code and excel manipulation.
Part of it may just be picking up a language and sitting down and getting comfortable with it. I know from my friends who ended up not specializing in CompE they hated programming because they took fortran or something ancient so C/C++ is a little friendlier since it can be read more easily.

edit 2: I bought this book for $48 back in 2011 why is it worth $200 today?

u/TonyStarchimedes · 2 pointsr/AskEngineers

I used a prep book from Amazon and instead of the 90 day study schedule I think I crammed it into just under 30. I did the general test for both parts, though I went through and looked at the questions in the second half and the material I knew/didn't know was about the same for general and mechanical.

I had to take it in school before graduating, and I passed, but haven't really needed it now that I'm working. Good thing for the resume though as some places look for it.

u/e175956 · 2 pointsr/AskEngineers

This Book covers the general section and also on the NCEES website they sell usually sell a small (25 sample questions I think) book for the individual afternoon sections if you were also curious on that.

If you can do the lindberg book you will ace the test. The questions tend to be at least the level of the FE, sometimes a lot more involved.

u/ChEJobSearch · 2 pointsr/ChemicalEngineering

So that means you passed the FE. Do you mind if i ask you some questions? if u dont mind XD

  1. did you take the ChE FE exam?

  2. how did you study for it?

  3. tips when it comes to actually taking it? everyone said to abuse CTRL + F. but i was very annoyed when i took the test because on my exam, ctrl F did not function the same way it normally does, like say on a website, or on microsoft word, or on a online PDF file. it literally brings up alot of stuff at once and i cant scroll through the word search so i was barely able to use the ctrl f function....

    I took the exam in around middle of 2017. i am a 2016 graduate. I struggled HARD on the exam even though i studied this book or should i study the CHE specific one ? (never saw inside the book before. not sure if it will be good or not for what i need)

    that book was seriously easy. so I thought I was really prepped. turns out i wasnt. I also screwed up in a way because i studied heavily on reactor design. turns out, its not even ON the dam test.... (idk why i thought it was... even though i looked at the topic sheet. i think i confused kinetics with reactor design)

    i also kinda blanked out on some simple fundamental ChE questions, such as calculating heat duty on ... something... and a mass balance that required use of steam table.

    so after that, i lost all confidence in what i learned during school.....
u/Whatitsjk1 · 2 pointsr/ChemicalEngineering

>practice practice practice. Take those practice exams.

where are these practice exams? i only know of 1 (and the free one someone gave me where they already paid the $50 from when they took it) all the others just make claims that its "FE exam material"

>hardest part was the general section for me, ChemE part was long but quite a bit easier.

yeah the material i am using is the the subjects in it, at the very least, FELT like my uni courses. this practice exam i am taking is NOTHING like it. once i look at the solution, it is really easily solved, except, the equation they used isnt even in the FE reference manual, nor ones i even recall back in school. an example is the definition of work in terms of pressure and volume. i forgot the exact question of that form so i had to look it up.... except... they conveniently left that one out. (the w = ∫pdv one)

>don't over think it, lots of people are in the same situation (and still pass)

yeah i hear online that the cutoff to pass is somewhere in the 60% range. of course,there is no proof of this as the committee doesnt share it. but i mean, its a $200+ test.... i cant really see myself going to take it while my confidence level is so low after this practice exam....)

u/aka00devon · 2 pointsr/AskEngineers

If you're still in school, I would look at their library for review manuals first. I was able to find this: Lindeburg's Review Manual. In my opinion, this manual more than prepared me for the test because it is actually a lot harder than the FE.

Get the official practice test from NCEES and the official equation book. Use your FE calculator and the equation book every time you study.

It took me about 1 week to successfully study for the ChE version, and I thought it was rather easy. It helped that I was still a senior and taking a statics class, though. Don't stress. If you come from a good program (I'm from Pitt), you'll already have 80% of the knowledge somewhere in your brain.

u/ShesPinkyImTheBrain · 2 pointsr/AskEngineers

I bought this book and did all of the practice problems. You get a pdf manual to use during the test. You can download it from the NCEES website. It’s searchable and definitely helps to practice using it. I took mine in 2015 for civil so there may have been some changes since then. The university I went to offered review sessions that were open to non students. They weren’t free but were cheaper than most other options, maybe there’s a school near you that may offer them. Good luck.

u/ryan2332 · 2 pointsr/EngineeringStudents

I took the FE Electrical and Computer exam on Sat, Feb 27 and just found out today that I passed so I might be able to help you with studying for it

I started studying around the beginning of February.

  1. Like marvellousmedicine said, you most definitely want to look at the reference book they supply you. You will have it on the test and it's good to know where everything is in it. The reference manual is almost 300 pages long so it's good to know which keywords to type to get to the section you want to be in. The test is computer based now so the screen will be split between the reference manual and the actual test. (you can ctrl+f the book)
  2. I went through Lindeburg's FE Review Manual and the Other Disciplines Review Manual. My roommate rented the first book and it was a lot cheaper a month ago. My school's library had the Other Disciplines Review book that I could check out (for free). So your school might even have the first one as well. The reason I looked at the Other Disciplines Review book was because it had some other electrical sections that the first didn't have. There are also a lot of sample questions in the Lindeburg books. I would go through the sections and try to do the sample questions only using the FE Reference Manual as that will all you get to use on the test. The Lindeburg books are outdated. They were made before they changed the format in 2014 but the content and questions are still good.

    In the back of the FE Reference Manual they have all the topics that will be covered by the test as well as how many questions for each topic. The questions are terribly difficult and I didn't think they were trying to trip you up. I am more interested in power so the computer, communications, signals topics gave me the most trouble. If you have any more questions feel free to ask me.

    edit: here's what on the Electrical Exam and the Other Disciplines book is not worth whatever price is listed below. The electrical sections I looked at spanned maybe 30-40 pages. I would only look at it if you can get it from the library.

I used this book extensively to prepare for the exam. I think I did about 4 full practice exams before I did the actual test. I ended up passing the first time I took it. I highly recommend this book because it also is an excellent reference for all things engineering later on in your life.

u/Vilault · 2 pointsr/civilengineering

Yeah, I perfectly understand. Know that as harsh as it may seem though, there's always others in your same boat. Another thing to note: the questions in those practice books tend to be more difficult than those you would find on the exam, so getting used to those practice exam questions will make things during the actual exam seem a bit easier. I used the Michael R. Lindeburg one used and it ended up working out well. Again, don't be so hard on yourself because it's not an easy task but put in the time and you'll get by without a problem this time around.

In my opinion the best way to learn and understand the chaos of sub-atomic particle and their place is to start with the trying to understand the standard model. It is the model in which everything is supposed to fit. It's the big picture.

If you have time to spare, consider watching these video lectures

Or pick up this book meant for people not well versed in math

Or if you're a masochist and feel you're upto the task of really understand this stuff take a look at

That book tries to see the physics beyond the standard model, marching towards and inching closer towards the ultimate goal of physics.

u/MahatmaGandalf · 2 pointsr/AskPhysics

You sound like a great audience for the series I recommend to everyone in your position: Lenny Susskind's Theoretical Minimum. He's got free lectures and accompanying books which are designed with the sole purpose of getting you from zero to sixty as fast as possible. I'm sure others will have valuable suggestions, but that's mine.

The series is designed for people who took some math classes in college, and maybe an intro physics class, but never had the chance to go further. However, it does assume that you are comfortable with calculus, and more doesn't hurt. What's your math background like?

As to the LHC and other bleeding-edge physics: unfortunately, this stuff takes a lot of investment to really get at, if you want to be at the level where you can do the actual derivations—well beyond where an undergrad quantum course would land you. If you're okay with a more heuristic picture, you could read popular-science books on particle physics and combine that with a more quantitative experience from other sources.

But if you are thinking of doing this over a very long period of time, I would suggest that you could pretty easily attain an advanced-undergraduate understanding of particle physics through self-study—enough to do some calculations, though the actual how and why may not be apparent. If you're willing to put in a little cash and more than a little time for this project, here's what I suggest:

  • Pick up a book on introductory physics (with calculus). It doesn't really matter which. Make sure you're good with the basic concepts—force, momentum, energy, work, etc.

  • Learn special relativity. It does not take too long, and is not math-intensive, but it can be very confusing. There are lots of ways to do it—lots of online sources too. My favorite book for introductory SR is this one.

  • Use a book or online resources to become familiar with the basics (just the basics) of differential equations and linear algebra. It sounds more scary than it is.

  • Get a copy of Griffiths' books on quantum mechanics and particle physics. These are undergrad-level textbooks, but pretty accessible! Read the quantum book first—and do at least a few exercises—and then you should be able to get a whole lot out of reading the particle physics book.

    Note that this is sort of the fastest way to get into particle physics. If you want to take this route, you should still be prepared to spread it out over a couple years—and it will leave a whole smattering of gaps in your knowledge. But hey, if you enjoy it, you could legitimately come to understand a lot about the universe through self-study!
u/charlysotelo · 2 pointsr/Physics

I'm no physicist. My degree is in computer science, but I'm in a somewhat similar boat. I read all these pop-science books that got me pumped (same ones you've read), so I decided to actually dive into the math.


Luckily I already had training in electromagnetics and calculus, differential equations, and linear algebra so I was not going in totally blind, though tbh i had forgotten most of it by the time I had this itch.


I've been at it for about a year now and I'm still nowhere close to where I want to be, but I'll share the books I've read and recommend them:

  • First and foremost, read Feynman's Lectures on Physics and do not skip a lecture. You can find them free on the link there, but they also sell the 3 volumes on amazon. I love annotating so I got myself physical copies. These are the most comprehensible lectures on anything I've ever read. Feynman does an excellent job on teaching you pretty much all of physics + math (especially electromagnetics) up until basics of Quantum Mechanics and some Quantum Field Theory assuming little mathematics background.
  • Feyman lectures on Quantum Electrodynamics (The first Quantum Field Theory). This is pop-sciency and not math heavy at all, but it provides a good intuition in preparation for the bullet points below
  • You're going to need Calculus. So if you're not familiar comfortable with integral concepts like integration by parts, Quantum Mechanics will be very difficult.
  • I watched MIT's opencourseware online lectures on Quantum Mechanics and I did all the assignments. This gave me what I believe is a solid mathematical understanding on Quantum Mechanics
  • I'm currently reading and performing exercises from this Introduction to Classical Field Theory. . This is just Lagrangian Field Theory, which is the classical analog of QFT. I'm doing this in preparation for the next bullet-point:
  • Quantum Field Theory in a Nutshell. Very math heavy - but thats what we're after isnt it? I havent started on this yet since it relies on the previous PDF, but it was recommended in Feynmans QED book.
  • I've had training on Linear Algebra during my CS education. You're going to need it as well. I recommend watching this linear algebra playlist by 3Blue1Brown. It's almost substitute for the rigorous math. My life would've been a lot easier if that playlist existed before i took my linear algebra course, which was taught through this book.
  • Linear Algebra Part 2 - Tensor analysis! You need this for General Relativity. This is the pdf im currently reading and doing all the exercises. This pdf is preparing me for...
  • Gravity. This 1000+ page behemoth comes highly recommended by pretty much all physicist I talk to and I can't wait for it.
  • Concurrently I'm also reading this book which introduces you to the Standard Model.


    I'm available if you want to PM me directly. I love talking to others about this stuff.
u/_imjosh · 1 pointr/AskElectronics

maybe check out this book and see if you can do a little better with it. it still has math, but you can't really get around all of it:

you at least have to be able to do some ohms law and some basic calculations. A lot of other things have seemingly impenetrable calculus behind them but I've found a lot of the time you can just read a data sheet and they'll give you some simple formulas that you can just plug into that work well enough. You don't need to know how they came up with the formulas, just plug in your parameters and go.

You should go on youtube and watch some videos of people repairing amps. there's lots of good ones and you can pick up a lot of stuff through osmosis. also check out EEVblog.

lastly, instead of messing with your nice guitar amp, build a cheap one yourself and mess with it. there's tons of schematics online you can use and it's pretty fun to build one. I put this one together and I really like it: You can buy all the parts from

Wow, thanks fro the great answers /u/crb3 ! Really interesting stuff.

Number 3 I'm going to read through really slowly again to try to makes sure I get it all. Reverse protection diode makes sense. I think I can leave it out since I am using only 9v DC from the wall wart so it'd be hard to get it backwards like a battery. It seems like increasing the value of C3 would allow a larger reservoir of power and less sag?

One question, why does it matter it it is a 0.1 uF MLC cap vs some other type of capacitor, i.e., What desirable properties are exclusive to MLC?

This is exactly what I has hoping for. I'm slowly working through this book now to get a better understanding of this stuff, but practical explanations like the ones you provided are really interesting and provide an awesome supplement to what I have learned so far from the text book!

Next step is the breadboard to try some of this stuff out!

We were assuming PoE which is more than likely 48v and frequency dosent even make sense in the context as its DC.

u/codekaizen · 1 pointr/windows10iot

Electronics is both easy and hard. The easy parts are following a schematic and plugging existing circuits together. This is usually much easier with digital electronics since all the electronics are doing are turning the current on and off or bringing the voltage high or low. The hardest part is making sure you connect all the wires correctly, and most devices are protected, and voltages are low, so crossing wires won't fry the device (though LEDs are easy to burn out). You can get very far with this "lego" mindset to circuit design. If you want to understand how current flows through an electrical network, and why resistors need specific values, how analog circuits work, and why digital signals need certain components like capacitors, then you'll need to invest more time in understanding electrical theory. This book is really good for that:

If you want to do it all on your own and have 0 experience you are going to have to learn a lot about programming and electronics.

You can start here for programming:

For electronics start here:

Once you've done that then I suggest you start buying Arduino kits etc. I'm not saying you need a lot of experience to start with Arduino, but if you are looking to make a commercialized project and have a budget I think it's better to know what to buy before you start throwing money away in things (e.g. kits) you won't even use.

I would highly recommend Art of Electronics. I've read dozens of books on this category and it is by far my favorite; useful both for initial instruction as well as later reference. Yes, it is expensive, but IMHO is well worth it.

How does Roark's compare to Shigley's?

u/GeckoAttack · 1 pointr/MechanicalEngineering

There's two textbooks that are commonly used to teach material behavior and mechanical component design (such as springs, bearings, etc). Both these textbooks are what I had to learn with.

Both these textbooks are easily to obtain if yer a pirate, as well as the solution manuals. They start fairly basic, however, they quickly go quite in depth. Shigley will probably be most useful for you, but definitely flip through them both. There will be a lot of over-lap content wise. I doubt you will find any textbook material on starter springs specifically because they are a specialty spring, however, mechanics of springs still apply to them.

Have fun :p Component design can get very complicated and convoluted so try and not get frustrated if things don't make sense. Let me know if you have any more questions, and feel free to PM at anytime. I can't promise I'll have a good or correct answer for you all the time, but I can try. Component design was actually one of my least favorite classes so it's definitely not my strong suit, but I understand the majority of what is taught in Shigley's and Dowling's.

Talking about one universal electric field is counterintuitive. While RRC is technically correct, (EM fields do obey superposition, and are defined throughout all space), this is semantics and detrimental to learning if you are not an expert. Unfortunately, this is reddit, where semantics are the most important aspect of a post. There ARE individual electromagnetic fields. If you want, you can say that these all add together to form one giant universal field, but why would you (considering most drop off to ~zero in a relatively short distance)? When it comes to the universal aspect, think of the electromagnetic force as being universal.

To get to the questions.

  1. Not really. Electromagnetic fields are somewhat mathematical constructions. In fact, you can't actually measure an electric or magnetic field; you can only measure it's influence (the force it produces). I have always been taught that sources create electromagnetic fields. That is, distributions of charged particles create electric field, and current distributions create magnetic fields (these are static fields). In electrodynamics, electric and magnetic fields exist simultaneously. So much so, that they depend on one another. This all comes from Maxwell's equations. Maybe modern interpretation says that the electric field is more fundamental than charges, but I have never heard this before, and it is definitely not what they teach in university. This may be some more advanced and therefore subdued theoretical stuff.

    I can't actually DEFINE a GENERAL electromagnetic field in a common definition. I can only tell you that there are a set of partial differential equations that define how EM fields behave (Maxwell's equations, Lorentz force law), and solutions to these equations are electromagnetic fields.

  2. Do not think of electric fields in this matter. It isn't incorrect to say that there is a universal electromagnetic field, but it is not very insightful. It's better to think that charged objects create these fields, which affect other charged objects.

  3. Generally speaking, if there was no charge in the universe, there would be no electromagnetic fields. Again, you are confused with electromagnetic theory terminology. I recommend picking up a copy of Griffiths book on electrodynamics if you are interested in the subject matter.

  4. Yes. Classically, mass creates gravitational fields, while charges create electromagnetic fields. If two charges are placed near each other, they will experience an electromagnetic force, with it's strength and direction determined by the particle's position (as a function of time) and charge. Masses are similar, except the force is the force of gravity.

    Also, light does not propagate THROUGH electromagnetic fields. Light IS propagating electromagnetic fields. Light is known more generally as electromagnetic radiation, and it is simply energy that propagates in a wavelike fashion out to infinity, generated from the motion of charged particles.

u/starkeffect · 1 pointr/AskPhysics

You should probably start by cracking open a copy of a good E&M book, like this one, and learning the science, rather than relying on Einstein quotations.

Of course, that assumes you've already learned integral and differential calculus (which any 19-year-old science or engineering student has).

u/Alloran · 1 pointr/exjw

I do highly recommend Genome by Matt Ridley and A History of God by Karen Armstrong. It looks like Before the Big Bang might be a great idea too.

However, I'm noticing a bit of redundancy in your stacks and don't want you to get bored! In the presence of the other books, I would recommend Dawkins' The Ancestor's Tale in lieu of The Greatest Show on Earth. (Although, if you're actually not going to read all the other books, I would actually go the other way.) Similarly, I would probably choose either to read the God Delusion or a few of the other books there.

Other recommendations: how about The Red Queen by Matt Ridley, and The Seven Daughters of Eve by Bryan Sykes? These occupy niches not covered by the others.

The popular expositions on cosmology all look supremely awesome, but you should probably choose half of them. Another idea: read just The Fabric of the Cosmos by Greene, and if you love it, go ahead and learn mechanics, vector calculus, Electrodynamics, linear algebra, and Quantum Mechanics! Hmm...on second thought, that might actually take longer than just reading those books :)

u/thirdtimesthecharm · 1 pointr/Physics
u/guenoc · 1 pointr/Physics

Sweet. I think the best curriculum to approach this with, assuming you're in this for the long haul, would be to start with building a good understanding of calculus, cover basic classical mechanics, then cover electricity and magnetism, and finally quantum mechanics. I'm going to leave math and mechanics mostly for someone else, because no textbooks come to mind at the moment. I'll leave you with three books though:

For Math, unless someone else comes up with something better, the bible is Stewart's Calculus

The other two are by the same author:

Griffith's Introduction to Electrodynamics

Griffith's Introduction to Quantum Mechanics

I think these are entirely reasonable to read cover to cover, work through problems in, and come out with somewhere near an undergraduate level understanding. Be careful not to rush things. One of the biggest barriers I've run into trying to learn physics independently is to try and approach subjects I don't have the background for yet: it can be a massive waste of time. If you really want to learn physics in its true mathematical form, read the books chapter by chapter, make sure you understand things before moving on, and do problems from the books. I'd recommend buying a copy of the solutions manuals for these books as well. It can also be helpful to look up the website for various courses from any university and reference their problem sets/solutions.

Good luck!

u/jon_stout · 1 pointr/AskScienceDiscussion

Hard to say. There's a massive number of steps necessary to reach our current technological level -- I could easily see setting up the smelting and manufacturing and mining needed to create a modern smartphone taking lifetimes. And that's not even taking into account the basics of agriculture and agricultural technology -- that, more than anything, determines whether or not civilization is possible.

Edit: At the same time, though, having the knowledge of base principles available might speed things up in some ways. Knowing that an airplane or space travel is even possible, for instance, might ease up or help focus research in those areas.

If you're looking for a good book to read on this subject, I'd suggest The Knowledge: How to Rebuild Civilization in the Aftermath of a Cataclysm by Lewis Dartnell.

Three steps, in no particular order:

  1. Go to Amazon or a good used book store and pick up Warriner's English Grammar and Composition. This has to be the best in-depth grammar course. Here's a link to the Grade 12 edition.

  2. The Elements of Style is an amazing reference that fits in your laptop bag, backpack, or pen tray of your desk. I wouldn't want to learn English grammar from this book, but once you know it, it's a good tool to refine and hone your skills with it.

  3. Learn another language. I remember when I first started studying Italian and came across a chapter on gerunds and had to learn what the bloody hell a gerund was before I could learn the Italian method. And most of the things you mentioned, I learned how to do in English because I was learning them in other languages.

> If there were fewer classes then maybe I could agree with this, but the problem is that while there are a good number of characters it's for a large variety of classes, meaning you might only have two or three of a class at a time. This makes it riskier to sacrifice one.

I think the choice is usually less severe than that. One consequence of the profusion of classes available is that you'd be very hard-pressed to use all of them in one playthrough. Going back to FE7, Serra and Priscilla each represent the only unit of their class available, and so are quite different by the end of the game, despite starting out very similar. As a result, you'd rarely use both of them under normal circumstances. So while sacrificing one early on may cut you off from a class entirely, it won't really hinder you significantly.

Your spelling and grammar need a lot of work, especially around the website. Clear spelling and grammar allow the reader to understand what you are saying. You can have the best story in the world, but if no one can understand it you won't get far.

Working on your spelling will also help to create an air of professionalism. People are entrusting you with their finances when you ask them to buy your comic online. Proper spelling and grammar will help you seem dedicated, trustworthy and serious about your series and its readers.

The Elements of Style by Strunk and White are a nice and easy to read introduction to things you should or should not be doing grammatically. As you write, try to read the sentences out-loud to yourself as a narrator would. Make sure they still make sense and are easy to understand even when spoken out loud. Most desktop office software has spellcheck included, along with most web-browsers. Even if you can't get Word, there's a program called "Open Office" that you can download for free, and it works the same way. See if you can hire a friend to check over your writing for you after you have finished your own edits.

I don't intend to be overly harsh, but I don't want to be disrespectful by mincing words with you either-- the artwork is poorly executed and generic looking. It's not the worst art I've ever seen, but you could be doing a lot more. Anatomy, perspective, composition design, character design and paneling are all things that you need to work on, and it's great that you're getting experience by doing this comic. Just do as much reading as you can (go to the library in addition to looking up tuts online) and get as much practice as you can get. I think that doing something like life drawing would help you a lot with your action poses...Have you seen the different things on the sidebar?

I was raised Christian and went to a fundamentalist highschool. I started questioning things when I realized my faith required me to suspend my rationality. Read some books on the historical accuracy of religious claims. My thought was always, "Well if what all these people say is true, it should hold up to rational scientific inquiry." The more I dug, the more I realized that it never could. I fought and fought with myself. Christianity (especially of the fundamentalist flavor) has this built in mechanism to dissuade disbelief. You are constantly indoctrinated to see any doubt that enters your mind as evil, sinful and to simply "pray the doubt away". I'm sure you know of this. Keep fighting, let reason and logic be your guide.

Some books that helped me on my way to breaking free:

A History of God by Karen Armstrong

The God Delusion by Richard Dawkins

Pale Blue Dot by Carl Sagan

I also recommend this youtube series by user Evid3nc3.

Those should give you alot to think about.

Remember the most important thing is to decide for yourself. Question everything and never take something as truth from authority simply because they are an authority. See if it makes sense, find the documented evidence that backs up the claims. The light may hurt at first.

This book will help you understand the neurological foundation for the sensation of self.

Um, to be honest I haven't read much from neuroscience other than Libet's Experiment and the clinical neuropsychologist Paul Broks saying, “We have this deep intuition that there is a core… But neuroscience shows that there is no center in that brain where things do all come together.”

There are some articles and books I have in my reading list, but once you get that this can be easily confirmed in DIRECT EXPERIENCE, the other materials are just superfluous, IMO. Here, I'll share them anyway.

“Who’s There?” Is The Self A Convenient Fiction?

What Exactly Is the Self? Insights from Neuroscience

And check out The Ascent of Humanity for a thorough discussion of the implications of the separate self on lots of aspects of our (collective) lives. Eisenstein traces all of the converging crises of our age to a common source, which he calls Separation. It is the ideology of the discrete and separate self that has generated these crises; therefore, he argues, nothing less than a "revolution in human beingness" will be sufficient to transform our relationship to each other and the planet.

u/JayaravaRaves · 1 pointr/Buddhism

The Ego Tunnel, Thomas Metzinger.

Reading this book liberated me from the lingering doubts I had about the supernatural. It shows that even when an experience is vivid, compelling, or even hyper-real that it is not necessary to take it as confirmation of vitalism, dualism or any other variety of supernatural thinking. Supernature is superfluous.

Our explanations of such experiences are usually wrong because they are based on cultural assumptions and an inability to really think analytically. It turns out that human's are really bad at solo reasoning and, more often than not, fall into fallacies and biases. We extrapolate our private experiences into ontological conclusions and we are almost always just wrong. Liberated from the mill stone of pre-scientific thinking about experience, we can begin to pay attention to what is actually happening in experience without all the overlays from culture and tradition.

Most of us are so loaded up with half-understood doctrine that we have no possibility of having an experience without unconsciously and automatically overlaying it with interpretations drawn from our existing beliefs. Thus we never really pay attention to the qualities of the experience itself. We're always dealing at one layer of abstraction remove. Most of the Buddhism we've learned just gets in the way of experience in the end.

I spent the first 10 years of being a Buddhist reading dozens of books, and the second 10 years discovering that most of what I read was useless or wrong or both. Metzinger's book might help others take a shorter route. He's completely wrong about Buddhism, but it's still the most important book on how the mind words that I've read because of how it make me reconsider my own conclusions.

u/hb9nbb · 1 pointr/space

i think thats actually not possible. I believe thats because you need to expand the flow to derive thrust and making the "bell" long enough to align the (now atmospheric pressure) flow exactly with the slipstream is impractical (it weighs too much). It might be possible if you were building a test article (ie. a rocket that didnt actually go anywhere, so it had no thrust/weight requirement). In any other configuration, whatever bell size you choose will be suboptimal in some regime. (ie. underexpanded at sea level, or overexpanded at altitude, etc.)
(there are variable geometry nozzles, and in fact thats what the aerospike is supposedly "better" at), but doing that in metal is quite expensive in weight.

I remember working this out for myself while reading Sutton about 10 years ago, but i cant remember why now.

Another fun little thought exercise is the "ice rocket" (the one that actually produces ice in the exhaust becuase of the expansion). This apparently can actually occur.

u/RUQpains · 1 pointr/IAmA

tl;dr: Yes. You gain additional velocity from a spinny Earth by launching east from the equator versus launching from Cape Canaveral, which either means you can use a rocket with less propellant (cheaper) or put more mass in orbit.

Yes. Dig this latitude map. I'm not sure when what we're talking about becomes actual Rocket Science, but we're close.

Check out this link regarding the Delta V (that's delta vee and not delta five, which makes googling for this stuff suck beyond imagination). The idea is that by launching east at the equator you get more of a velocity boost from the rotaty Earth than you do elsewhere. I compared the numbers I linked to in my (Sutton)[] and they disagreed, so I won't quote them. You can feed the difference in velocity gained launching east from the equator versus Cape Canaveral back into the Tsiolkovsky equation (and you can google that shit all day long) and eventually work out how much more mass you could've put into orbit if you launched from the equator versus Cape Canaveral.

You might also check out Wikipedia's article on Delta Vee and work to gain your own understanding of this, since I am absolutely not a rocket scientist.

u/FullFrontalNoodly · 1 pointr/rocketry

What you seem to be not understanding is that using a simulator is far and away the quickest, easiest, and because it is completely free, the cheapest way to learn how rocket science really works. Using a simulator will save you countless hours when it comes to making a rocket over just shoving some chemicals into a tube and crossing your fingers. And speaking of fingers, it just might save you some of them, too. Because people do lose fingers playing with rockets.

Since you seem to be familiar with electronics, I'll make a comparison with LTSpice. Instead of spending hundreds (if not thousands) of dollars on a parts library and expensive test gear you test all of your designs on a tool that is completely free.

This isn't gatekeeping. It is exactly the opposite. It is enabling.

As to sources to learn, one of the best resources is linked right in the sidebar:

u/Aerothermal · 1 pointr/thermodynamics

Establish the properties you know and those you care about finding - Viscosity, thermal conductivity, molecular diffusion coefficient, fuel/oxidiser requirements (i.e. mass conservation) for example.

Here's a few things to think about:

  • When analysing the working fluids, you'll care about properties such as temperature, pressure, specific volume, and enthalpy. You might need a pump/turbine to deliver your fuel or oxidiser, and worry about enthalpy throughout the cycle. See thermodynamic cycle of a reaction engine.

  • When sizing your nozzle and throat area you'll probably at some point want to know you characteristic velocity C, which is the (chamber pressure)(throat area)/(mass flowrate). Chamber pressure is very much related to the heat of combustion and it would be nice to model this, either steady state or transient.

  • To a mechanical engineer, the combination of pressure and temperature dictates how you design your chamber (thermal expansion near to joints/component interfaces, principal stress, oxidation, creep properties, are all important). You will be thinking about how to keep the walls of the chamber and nozzle cool - see how the Saturn V rocket engines (F-1 engines) routed their fuel around the nozzle, which pre-heats the fuel, and cools the nozzle so that it can survive the high temperature exhaust. Some engines might need thermal barrier coatings or ablative coatings. It would be interesting to analyse whether any of this extra thermal protection is necessary.

Bates, White, and Mueller are all co-authors of this book: Amazon link, which is commonly referred to as the "BMW" book because of their names.

Side note - it looks like there's a second edition, so might want to go for that. The first edition is fine so far to me, probably just has some outdated numbers or notations.

It sounds like you’re looking to be a spacecraft orbital analyst, or a mission analyst and trajectory planner as we call them at my company.

If this is your dream, choose aerospace engineering and choose a school that has a strong focus on space, because some are better for aircraft. CU boulder is a great example of a school that invests just as much if not more in their space systems research.

You want to start looking into spaceflight dynamics and astrodynamics. The best book for this would be “fundamentals of astrodynamics” by Bate, Mueller, and White. That book is a classic, it’s almost 50 years old but it’s the gold standard of this field. And it’s cheap as hell. You can find it here:

it’s only $15 with prime one day shipping!

I also highly recommend looking up beginner videos on YouTube to supplement the text. Once you have the basics down (orbit and conic geometry, rocket equation, etc) I’d download NASA GMAT (it’s free) and start waking through some tutorials on that software. If you go to college for engineering, usually the school will have STK (systems tool kit) available for free download as well. Both softwares are used heavily throughout the industry.

And play kerbal space program, it’s a fun way of learning and visualizing some of this stuff.

u/arksien · 1 pointr/KerbalSpaceProgram

Quite literally, it means change of velocity. When people talk about "needing enough dV to get somewhere," what they mean is that, they need enough fuel to get there. I'm going to use arbitrary numbers right now because I'm too lazy to look up the actual ones, and simple is better anyhow.

Lets say you have a craft in low kerbin orbit. You want to go to the Mun. You're currently traveling 2300 m/s. In order to intercept the Mun, you need to be going 2900 m/s. Once in the Mun's sphere of influence you're traveling at 800 m/s, and you need to burn retrograde until you're traveling at 200 m/s to achieve orbit. The opposite is true to achieve escape velocity, and then once you escape, you're traveling 3000 m/s and need to reduce your speed to 2700 m/s for your periapsis to allow re-entry to kerbin.

(Again, these numbers are ball park, not exact).

So, the dV you need to get to the Mun's SoI is 600 m/s (from 2300 to 2900). A capture burn is 600 m/s, and an escape burn is 600 m/s. A final burn for entry is 300 m/s of dV. So, the total dV your ship needs in this scenario to go for the whole trip is 2100 m/s of dV.

Now, this does get a little more complicated when in an atmosphere, because you'll burn more fuel trying to escape than you would in a vacuum. Also, the effect of gravity on your craft is going to change the efficiency of your rocket depending on how much vertical and horizontal velocity you have at various points of your burn. When people say they're building a ship with ideal dV, what they typically mean is "I did the math and found that if I manage to fly the most optimal flight path available to use my fuel the most efficiently, I need enough fuel to perform dV burns at various points in the trip totally this number." The math behind all these variables gets a lot more complicated, and if you really want to nerd out, "Fundamentals of Astrodynamics" will help you to understand what the hell is going on just a bit better. I like that book because it has the math, a brief explanation, and diagrams all in one package. You'll learn all about various transfer types too!

...or you can just download mods that do the work for you, like many people! Or, you can just wing it and hope for the best like even more people! I mean, worst case scenario it's time for a rescue mission, right?

> I gotta look at some orbital mechanics books

If you really want to go through with that I highly recommend "Introduction to rocket science and engineering". It goes reasonably into depth but is still accessible with a decent highschool math and physics background. Besides orbital mechanics it covers the basics of pretty much all aspects of rocket science (history, thermodynamics, orbital mechanics, propulsion elements etc.) It is a bit pricey though, you probably want to find it somewhere cheaper.

If you're a bit more advanced (primarily in math) you could also checkout "Fundementals of astrodynamics" which is nice and cheap or "Orbital Mechanics for engineering students" if you really want to make it your job.

I am a mechanical engineer by trade but I am really interested in spaceflight and orbital mechanics so in the past months I have been catching up with those books.

u/readytofall · 1 pointr/KerbalSpaceProgram

The math for the parched comics stuff actually is not that hard. It's just know what you are looking for and plug it in. Basic algebra. Once you stray from that and do the cordinate transformations and into the the non patched conics stuff it gets a lot harder.

Kerbal player?

If you're really diving into orbital mechanics, this is what I highly recommend: Fundamentals of Astrodynamics. "Bate, Mueller, White" is generally considered the intro textbook in aeronautical engineering. It's a long-time classic (and cheap!), and is written by three professors of astrodynamics at the US Air Force academy.

>"Develops the basic two-body and n-body equations of motion; orbit determination; classical orbital elements, coordinate transformations; differential correction; more.

>Includes specialized applications to lunar and interplanetary flight, example problems, exercises."

u/Kenira · 1 pointr/space

I'm sorry if this is not what you asked, but if you have at the very least high school or ideally some university level knowledge of math it sounds like Fundamentals of Astrodynamics might be at least part of what you are looking for? It's focus is orbital mechanics and maneuvers in space, including interplanetary trajectories. While i have not finished it, it is so far really good and widely used. Bonus points for being really cheap. Although again, you do need math to really appreciate this book. Without going through the math you can still learn some things from it, but i am not sure if this book would still be that fun to read.

u/chronicENTity · 1 pointr/IWantToLearn

I found this book quite useful back in high school. I haven't seen/touched it in 10+ years, but the concepts have been tried and true for many many decades. It's math-based and is written by Air Force Academy professors. It definitely doesn't cover everything, but it can get you started in the right direction. It's also not too hard to grasp as far as concepts go, but knowing Calculus and the likes are going to make it fully understandable.

I can't help you with the French part but in America the standard is this. Most people refer to it as BMW for the authors' names. There might be translations of it; I don't know. It's actually a surprisingly fun read. The first few pages talk about Newton with a kind of religious fervor that you never see in a textbook. It's beautiful. Also, it's damn cheap.

My orbitals professor also wrote a more condensed pdf textbook which he gave just to us. It's actually more clear than almost any other engineering textbook I've used. If I can find it, I'll post it.

u/aerobit · 1 pointr/programming

EE yes. If you can EE than you can program. Taking a few CS courses will teach you the finer points of programming. But if you want to play with hardware than EE is the way to go.

Between EE and CS, both types learn programming. Focus on EE if you are thrilled by hardware. Focus on CS if you love logic puzzles and high level abstractions. FYI EE pays more and you can always get a programming job with an EE. The reverse is not true.

(Although I have to say that most EE's I know are terrible programmers. But that doesn't seem to stop them.)

I think a book that would be perfect for you is
The Art of Electronics
. The first half is all basic electronics. Then it gets into logic circuits and finally simple computer circuits.

One nice thing about this book is that the chapters are very well organized. So if you don't want to learn everything there is to know about transistors, just read the first few pages of the transistor chapter and the move on.

Last summer while on holiday I was laying on the poolside chairs (hiding from the intense midday sun, the sea/pools were empty around noon), reading The Art of Electronics. I had it on the foot side on my chair, laying on my stomach so you could see the book when going around.

The hotel staff was running around, giving out cold water, entertaining kids etc. One of them went by me, did a double take on the book (I was on some page with a lot of circuit diagrams, graphs, ... ), stopped and asked if he could have a look. I said sure, he picked it up, flipped through it, shook his head and went away without saying a word.

Not really sure what he though, but it certainly wasn't the standard beach reading material.

u/macegr · 1 pointr/electronics

Glad to see you're approaching this from the correct angle. We get this sort of question here all the time, but it's usually "how do i electronics" and they get upset when they find out math is involved.

Definitely follow the math up through precalc, calculus, and differential equations. Learn Laplace transforms if you have time. You'll also want to explore physics pretty far, much of it will apply when you least expect it. Electronics is a mix of applied physics and chemistry. Finally you'll want to learn some thermodynamics. Understanding heat transfer and energy will be pretty useful. For all of these, I would just hunt down some college textbooks and some related Schaum's outlines.

While you're doing that, make sure to dabble in electronics to keep you focused. Build up some assembly, soldering, and possibly circuit layout skill. Definitely find this book:

An op amp is a differential amplifier with an enormous gain, something along the lines of 10^(6)

This causes some interesting things, for instance, with input voltages above, say 1/1000 of a volt, it will act as a comparator, the largest voltage immediately sending the input high or low.

Because of this high gain, it is easy to construct a circuit for an amplifier that is determined by the ratio of two resistors alone, the gain disappearing entirely from the equations.

Op amps can also be used to add DC bias to a signal.


These are some useful resources

I would recommend the Art of Electronics (or the ARRL Handbook) if you are looking for more of a reference style text. Very thorough, but not something you would want to read front to back.

Assuming you have your circuits basics down, a good text to really start learning how to design circuits would be Microelectronic Circuits by Sedra and Smith which is your undergrad text on introductory analog/digital circuits. This one you can definitely read front to back (but it's big). And then if you really want to get into the thick of things, you could read Analysis and Design of Analog Integrated Circuits AKA Grey and Meyer which is your advanced undergrad/graduate text on analog circuits. There are many alternatives to these texts, but these ones are basically bibles.

u/dragontamer5788 · 1 pointr/AskElectronics

I'll sketch you through some important steps, but there's seriously a lot of material here for this kind of approach. Its impractical that I'd hold your hand through the whole process.

The core of the design are the external DACs, so you need to read the datasheet.

This particular chip uses the SPI bus. In general, a bus is a way to communicate with many devices using fewer wires. SPI itself has multiple variants, this is the SPI Daisy Chain variant, which requires 3-pins to communicate with all devices. Page 17 of the documentation has an example.

Wikipedia has another example of how to hook up Although notice: the DAC088S085 does NOT have slave-select pins. So its a bit different than the Wikipedia example. There's also a SYNC pin, which is important for "frames". Basically, you send the SYNC pin low when you're done shifting the data (once you count 64 bits out)

Now SPI just describes how to get the bits to the DAC088S085. It doesn't actually tell you anything beyond that. You need to read the documentation (page 18 and 19). You can see that each DAC088S085 takes a 16-bit command, so if you have four of them... the SPI shift-register would essentially be 64-bits long.

In any case, you need to send 16-bits per DAC multiple times to set each of the individual DACs. So for example, if you wanted to set the 5th DAC on the first chip to 75%, you'd need to shift out: 0x5C00xxxxyyyyzzzz (where xxxx, yyyy, and zzzz are some command for the 2nd, 3rd, and 4th chip, due to Daisy Chaining).

If you wanted the 10th DAC on the 3rd chip to 25%, you'd need to shift out: 0xwwwwxxxxA400yyyyzzzz (where wwww, yyyy, and zzzz are some command for the 1st, 2nd, and 4th chip, due to Daisy Chaining).

A "full" example, would be if I set the 1st chip 3rd DAC to 25%, the 2nd chip's 8th DAC to 50%, the 3rd chip's 12th DAC to 75%, and the 4th Chip's 1st DAC to 100%: 0x34008800CC001FF0.

To set all 32 DACs to a specific value would require 8 commands like that to be sent through the bus.

As you can see, the problem with a "bus" is that it requires more complicated software to handle. That's the tradeoff: fewer pins, but more complicated to program. In any case, read page 18 and 19 until you understand the numbers above. You can't just talk with the DAC immediately, you need to "think" how to shift the data into the correct DAC. Furthermore, each DAC chip controls eight different internal DACs. To set each DAC requires you to understand the communication protocol, which is described on page 18 and 19.


The DAC088S085 looks like it also requires an external voltage reference.


Now, to answer your question about OpAmps, here's a tutorial on the Inverting Amplifier. Once you understand that, go read page 21 of the documentation. As I described in another post, OpAmp design is a 3rd year subject for electrical engineers.

You'll have to understand the concept of negative feedback to really understand why the OpAmp circuit works. Chapter 4 of "The Art of Electronics" is an excellent chapter on OpAmps. Although... the discussion of negative feedback is in Chapter 2. But yeah, read Chapter 2 to understand negative feedback, Chapter 4 to understand the basics of OpAmps. (Chapter 5 for precision use of OpAmps)

And no, I'm not going to teach you OpAmps. But there's plenty of OpAmp material in print. If you don't feel like spending money... go to a library. Most online tutorials are inadequate IMO compared to a good textbook.

While you're at it, read chapter 2 and 3 to study up on some basic transistor designs. I'm gonna bet that your circuit will require a transistor amplifier or two scattered about.

I saw it followed pretty religiously in aerospace and I'd guess that automotive does too, as I believe SAE was heavily involved with creating them (not positive though).

My current job (industrial components) uses them as a guide and reasonable starting point but is not bound to them.

Other companies I interned at just drilled to whatever size was available and hoped it worked.

It really depends on how critical the components are, how regulated the industry is, and how likely you are to get sued. If a component fails, "I followed best industry standard and practices" holds up a lot better in court than "I guessed and it seemed to work". There are a ton of other tolerance standards and about 1500 pages of Machinery's Handbook is largely devoted to them. It's worth browsing through some time, it's really mind blowing how standardized everything is. They seem simple but there are at least 100 pages devoted purely to dimensions on bolts.

It's a bit of a mixed bag. If you're looking to buy new, your basic choices are new Asian import or old iron. Standard Modern is Canadian, Emco and Lion is European, and I believe Monarch and Hardringe still make lathes every now and then - all for between $16 and $80k, way out of your price range. CNC won't talk to you unless you're into the 5 digits either.

South Bend is made in Taiwan now, along with Grizzly, Precision Matthews, Baileigh, and others - mostly from the same factories with different paint jobs. They are pretty good machines and can get you started. But the other option is finding an old lathe on Craigslist or through an industrial dealer and getting that going again. A lot of them are still very precise machines that need a little TLC, and if you're diligent in your search, you could end up with an amazing machine for practically scrap metal prices.

You can get anything down a flight of stairs, whether it's usable at the bottom is the harder question. Unless it's a hobby size lathe, you're not going to be carrying it down. They get really heavy very fast. But with proper precautions, ramps, levers, come-alongs, and chains, people have safely lowered machines weighing half a ton and more into their basements. How much of that you're willing to attempt is on you.

There's definitely something to be said about being self-employed. If you can pull it off, being your own boss is probably pretty liberating. I was actually having a conversation with my roommate last night about work and money, etc. He graduated college a few months back with a 4-year degree and now he's making $30k/year at a job he already hates after working there for a month. It does suck to feel like a pawn of the system - you work for pennies while other people profit immensely off of your productivity. So going freelance might ameliorate that problem for you.

In regards to printing PCBs, yeah, that's electrical engineering. There's a book my EE friend made me buy that you might find useful for that endeavor: Practical Electronics for Inventors. Though that link to American Amazon might not be the best based on your usage of the word "flat." I've been working my way through a different one - Essentials of Computing Systems, which I've found pretty cool. Starting with NAND gates (in a hardware simulator) it has you build up a fully functional computer, which you then write software for. Pretty cool stuff.

Luckily it's never been easier to start learning electronics. I know you want hands-on experience but you gotta learn some theory first - I'd recommend a book like Practical Electronics for Inventors to learn the basics (some people swear by The Art of Electronics but it is not a beginners book, rather more of a intermediate-advanced reference). Then something like the Arduino Starter Pack that will start you on the path to building circuits!

Along the way, watching electronics tutorials and teardowns on youtube, and taking apart stuff to see how it works would also really help.

Assuming you’re a beginner, and are starting with little to no knowledge:

I bought the 3rd edition of the book called “Practical Electronics for Inventors” by Scherz and Monk it starts from the basics and you slowly build more and more complex and practical circuits.

Another fun on by Monk is “The Maker's Guide to the Zombie Apocalypse: Defend Your Base with Simple Circuits, Arduino, and Raspberry Pi”

If you are looking for something more theory based (I wouldn’t recommend initially unless you’re just curious) there’s a whole slew of texts books depending on what exactly you’re interested in you can pick up for cheap at a used book store or on amazon.

Remember build slowly in the beginning until you get a good grasp on the content and have fun. Diving in too deep to quickly can overwhelm and kill morale.

I was the one suggesting that more northerly locations would be better situated to avoid temperatures driven to 45°C+, and you responded by pointing out that even Moscow "gets heatwaves" too.

I then demonstrated that Moscow has never experienced temperatures in the 40s. Ever.

A perfectly relevant refutation of your generalised exaggeration. That's all.

> water is going to vanish, everywhere?

Obviously not what I'm saying.

Some won't get enough, and some will get far too much. And some will even get just the right amount for some time - but at some point in a collapsing biosphere, not reliably enough in any one place to ensure sufficient crop survival and reliable harvesting to make agriculture viable.

No, I don't have a crystal ball, and can't tell you exactly where that point will be, but this extinction event is unfolding with unprecedented speed, and we are still accelerating it, so I really don't believe that ignoring uncomfortably pessimistic sources is a wise strategy.

> You're now blaming me for not engaging in threads I wasn't involved in?

Sorry, I was getting it confused with the other thread we're discussing similar matters in. I have to do all this on a crappy, broken smartphone since I don't use a computer, so no split-screen windows/advanced clipboard functionality/fancy keyboard for me.

It was referenced in this thread, not the other one.

> On the contrary, I've pointed out the "links" (really one link posted multiple times)

Since /u/Goochymayn posted the link to the projected effects here, I have posted a dozen different links that weren't this one in this thread.

> Man, you people are obsessed with this one website

Far from it, though a little stubborn in trying to encourage some sort of engagement with it on your part - it's sort of the opposite of cherry picking, to go on blithely claiming that it doesn't say what it does, and that the whole thing's just too silly to even acknowledge.

I read many websites, have read the book this summarises by Mark Lunas (FWIW, it won the 2008 Royal Society Book Prize and was turned into a National Geographic TV series, so it's not just some crappy little blog.)

And I agree it would be better if the summary had hyperlinked references. I don't post it here much/ever myself, precisely because of the lack of easy to follow hyperlinks to make it easier for people to check sources online. The book is better (books are always better than this internet rubbish.)

OK, you don't recognise it or any of its sources (though they've been bandied around here often enough,) - I will add some more links tomorrow when I've had some sleep, though it will be at the expense of speedily responding to your other posts (lots of busy-ness ATM.) I will come to them when time allows.

I accept that the descriptions of the effects at each temperature band may not be accurate. Which is why it would be interesting and useful to discuss what it actually predicts, and how much, if any merit there is to their arguments (it would be even better to discuss the book, but that's less feasible online in the temporary conversation cloud that is Reddit, given how few people have probably read it.)

It's less productive in the extreme, to only ever see it analysed by McPhersonite fanboys, too busy obsessing about the doom to look at it with a critical eye. But if they are accurate, then farming will self-evidently NOT be possible, because we will all be too extinct to practice it.

Other interesting topics exist of course, but they're pretty academic if we're looking anything like +7°C by the end of the century.

That too is an interesting topic in itself, and one I would like to see more people engaging in disputing, rather than just avoiding having to consider it at all on the one hand, or obsessively and unproductively doom-mongering about on the other.

They both seem like less productive (if understandably human) approaches.

I find it convincing enough to have committed to taking the measures I have anyway, though I try to keep an open mind.

> doesn't say what they claim it does. It literally doesn't say it.

It doesn't say exactly QUOTE farming will not be possible UNQUOTE, but FFS, it's predicting the sky effectively catching fire because of the methane content, superstorms at least as extreme as the ones that caused the Permian-Triassic extinction, with ""super-hurricanes” hitting the coasts [that] would have triggered flash floods that no living thing could have survived."

It says: "That episode was the worst ever endured by life on Earth, the closest the planet has come to ending up a dead and desolate rock in space.” On land, the only winners were fungi that flourished on dying trees and shrubs."

And you think agriculture will be possible in this?

It is true, this is at 5+°C, but they also state "Chance of avoiding five degrees of global warming: negligible if the rise reaches four degrees and releases trapped methane from the sea bed."

You've made no effort to refute any of this - you just refuse to engage with this source.

It explains the inexorable runaway temperature effect that will be (possibly has already been,) initiated, and so 4°/5°/6°/7°/+ is largely irrelevant - it's going up, up, up.

And the methane is already being released in observably huge quantities already at <1.5°C, so this does not look so unlikely that it's sensible to simply dismiss it to me, considering the fucktons of the stuff there is down there.

But hey, you've got potatoes and trees, so you'll be fine.

I (and probably other less optimistically- inclined folk here,) would be really interested in knowing why you, or other more optimistic folk, think this is not going to happen.

IF (and I freely admit that is not certain, but if) we're looking at anything like these projections coming to pass this century, then at some point this century, agriculture WILL fail.

And IF the runaway effect from all these tipping points we're burning through is real, then over some timespan, that's inevitable.

> A little emotional, aren’t we? The part where "the world" = "modern civilization"?

No. The part where everything bigger than a lystrosaur, including very probably humanity, is rendered extinct.

And actually I don't get emotional about it - I'm past that.

I get stubborn, and start building an Ark.

> The article they keep linking to doesn't say what they claim it does.

It claims unsurvivable, extinction-level conditions are coming, so yes - it does say what they claim (whether or not it's well-founded - that is a different argument. One you seem unwilling to engage in.)

> I've said that multiple times to them. They have no response for me. And neither will you, I expect. Read the goddamn article.

I have. And I can understand what it's saying. I'd like a reason to disbelieve it, but you're evidently unable to provide one.

I recommend reading the book (I ought to buy another one - lent it out, and never got it back.)

I haven't read it yet, but Six Degrees: Our Future on a Hotter Planet by Mark Lynas is on my wish list.

u/eff_horses · 1 pointr/changemyview

> The global temperature is increasing wildly

Define wildly. Since 1975 it's increased by an average of about .15 to .2 ^o C per decade and it's increased about 0.8^o C overall since 1880, with about 2/3 of that coming since 1975. It's probably increasing by a bit more than that now because global emissions keep increasing.

> in a few years many heavily populated areas will exceed "wet bulb" temperature, meaning they will become so hot that it would be impossible for human life to exist there

That doesn't seem to fit Wikipedia's definition of wet-bulb temperature, although I'll admit to being very unfamiliar with the term; do you know in what context McPherson used it?

It would help to know exactly what McPherson's temperature projections are. To me, the notion that the usual projections could render places currently supporting hundreds of millions of people uninhabitable within the next few years, or even decades, is tough to believe without hard numbers to back it up.

If you're curious for other sources, my impressions are based roughly on Six Degrees, by Mark Lynas and Introduction to Modern Climate Change, by Andrew Dessler. I think climate change is definitely capable of causing our extinction eventually, but it would require a lot of inaction on our part, and it would still take several centuries at least.

FE Industrial and Systems Practice Exam

u/DrBridge · 1 pointr/engineering

This may not be a perfect suggestion, but have you considered study materials for the field-specific FE test?

This study guide exists, and the testing company NCEES offers a PDF of the official reference guide (mostly equations, very surface level) for free here.

I don't know whether these would cover everything to the level of detail you want. However, they might be a good way to identify things you're rusty on so you can go back to your textbooks/class notes for more detail.

u/digitalosiris · 1 pointr/AskEngineers

The EIT/FE is not a hard test. But, it is a test of fundamentals, most of which you haven't used / forgotten in the past eight years. As I tell my students: take the test before you graduate, because your brain is like a sieve, and once you stop doing homework, that knowledge slowly seeps out.

As you're coming to it several years out my advice is to start by buying yourself one of those EIT prep books and working problems. The Lindeburg book seems popular. Figure out what you know and what you've forgotten.

Then check your local colleges that have CE programs to see if they offer FE prep courses. Ours does, it's run by Chi Epsilon (the CE honor society), starts about 8 weeks before the test and they get professors to come in on the weekends to review. Ours charges a very nominal fee (like $10 per session) and student feedback is quite positive. So if you have a CE program near, contact the department office and see if they have something similar.

Buy the FE reference manual that NCEES sells. As others have said, the bulk of the material you need to know will be in there. Know where things are found ahead of time.

Figure out which afternoon test you're taking -- CE or Other disciplines (formerly called general). As you're 8 years out, CE is probably the answer for you.

The real key is to know that you're not going to know everything and the test ultimately is designed to test how well you take tests. Know what you know very well, re-learn the familiar stuff so you are passable, and don't spend a whole lot of time on stuff you've completely forgotten or hated. Make sure you know your math, physics and statics and you're on your way.

The thing is since the FE covers general topics as well (calculus, physics, statics, ethics, etc), the PE book won't cover any of it.

I recommending getting this book.

I did practice problems with that and read the chapters and I felt the test was super easy.

u/soggy_pants · 1 pointr/EngineeringStudents

The FE is actually pretty easy with like a 75% pass rate. I took the test two years after graduation with about two weeks of studying and passed (mechanical engineer with a strong gpa).

You HAVE to get the official reference manual. You get this in the actual test and the more you are familiar with it the easier it is to find the relevant equations. That's like half the test--plugging numbers into the relevant equation. I used this review book and felt it did a good job.

Good luck and don't sweat it. Study through the main sections and make sure you understand basic math and physics.

u/BrujahRage · 1 pointr/AskEngineers

This is what I used when I took the exam last year. I loaned that same book to a couple of friends who took the exam this year, and they both passed. To be honest, it's overkill, as not everything in there will be on the current exams, but that coupled with the books available from NCEES will let you pick and choose the sections you need to study.

u/motank · 1 pointr/EngineeringStudents

I used Lindeburg's book.

In retrospect, it wasn't terribly useful except for an ego boost in some topics and really identifying what I was weak in. That being said, if you're doing reasonably well in school you should be fine for the FE. What I would do is review for your discipline specific exam. I didn't cover much for mine in school (Mechanical; didn't learn much, if any, HVAC stuff at school).

Basically a small handbook of all kinds of useful reference data, especially engineering and automotive related (need to calculate the pressure drop of a given fluid through a pipe of a given diameter flowing at a given speed? Need to re-jet a carburetor? Determine the maximum safe loading of a soft pine floor vs. an oak floor?) in addition to miscellaneous data (zip codes, how to perform CPR on babies and small animals, major poison and burn centers for your region of the US, names of various groups of animals like hamsters and crows). I got these as gifts for my groomsmen, since I prefer to give "useful" items like tools and books.

For basic (non-electronic) electrical stuff, I've heard good thing about the Navy's training materials, but I haven't read it myself.

For electronic circuits, I recommend The Art of Electronics by Horowitz & Hill. They just came out with a new version that's apparently more focused on modern digital circuitry (microcontrollers). This is the book that I used when I was learning analog circuits; it gives good descriptions of things like resistance/reactance/impedance, LCR circuits, transistors, oscillators, op-amps and other amplifiers, as well as RF circuits. I think my edition also covered some 7400 series logic and ancient microcontrollers.

This is the book used to teach students entering into carpentry and building construction where I'm at in the US:

It not only tells you how but why things are built the way they are. It gives you a primer on not only carpentry and construction but also the tools used in the trades, how to manage construction schedules (when to have electricians, plumbers, finish carpenters, etc. scheduled to show up) and how to manage construction cost (when to use engineered lumber and when not to, how to plant landscaping to mitigate heating and cooling costs, how to position the build on the lot you have to best take advantage of Sun, wind, and on and on).

It's aim is to take a complete novice and provide them with enough knowledge to start in the construction trades. Having said that, it is a bit dated so a supplimentary book with updates on the things that have changed would be a good idea to get in addition to this one. Having said that, if there is one book the vast majority of carpenters and builders in the US have read, this is the one.

Fundamentals of Astrodynamics, for example, is an old U.S. Air Force Academy textbook that will teach you a lot of basic rocket science and orbital mechanics.

Some less mathy but still very interesting and semi-technical options are How Apollo Flew to the Moon and To Orbit and Back Again.
