Reddit reviews Relativity: The Special and General Theory

QED, Six Easy Pieces, and Six Not So Easy Pieces are great reads for the interested layperson. Also, Einsteins original Relativity is great, and doesn't have super-complicated math.

It depends on the observer.

Einstein's books about relativity written by Einstein for the non-expert
-Helps you understand not only his theories well, but piques your interest in science a lot, and improves your way to approach all problems. His essays (in particular The World As I See It, be careful of edited versions on the internet which cut out parts they don't like about God, http://www.youtube.com/watch?v=3Y0_aNvH0Wo) are amazing as well.
