References: utastro.768 You may also find the newest edition of Modern Physics by Tipler easy to use (1979, I think). I've found this the easiest book to teach relativity from to sophomores and juniors. The simultaneity section is excellent, although the twin paradox does leave a little something to be desired. All the relevent results are derived using right triangle geometry, except E = gamma*mc^2 which, of course, requires an integral.
