Popular-science book on higher dimensions, string theory, many-worlds theory, and so on, written in the 1980s so not exactly up-to-date, but a useful refresher on the basic concepts and cultural background. Contains massive spoilers for Heinlein's All You Zombies and "He built a crooked house." The author has the interesting thesis that the problem with string theory is that the concept was stumbled on before the development of the math to do it properly.

By coincidence, this was my purse book while Stephenson's Anathem was my bedside book, which made an interesting juxtaposition.
