The other one i read was Death by Black Hole and Other Cosmic Quandries by Neil DeGrasse Tyson who is an astrophysicist. Some interesting stuff about the universe and, well, astrophysics. Coming at this one from a decent if not great science background (I read The Elegant Universe and was SO CLOSE to understanding it and am a huge Discovery and Science Channel junkie) i understood almost all of it. It started as a series of essays but did translate well to the book format. even got a quote
I don't want students who could make the next major breakthrough in renewable energy sources or space travel to have been taught that anything they don't understand, and that nobody yet understands, is divinely constructed and therefore beyond their intellectual capacity.
