A "real" book that's not hard (Score 1)

One of the best physics books I've read is "Space and Time in Special Relativity", by N. David Mermin. It was the Special Relativity (SR) textbook in my freshman physics course and is definitely a physics book rather than a book on physics; thankfully it also has tons of prose explanations.

SR is great to learn for those interested in some serious dabbling in physics, because while the implications are quite cool/profound (rulers flying past your head at .9c get shorter, etc), the math really isn't that difficult and the logic is very straightforward.
