This audio CD of Feynman's second collection of autobiographical bits is a lot of fun to listen to. The part about the President's Commission on the Challenger Shuttle disaster was very powerful and wryly funny. Feynman was such a scientist, so intent of finding things out that he simply ignored the conventions, if he was even aware of them, and his wide-eyed, naive search for answers was always a delight. The only part of this book I didn't like is the appendix- which was the entire Feynman report on the shuttle disaster. In all its dry, NASA acronym-laden ponderousness, written by a theoretical physicist for consumption by engineers. That didn't make for interesting listening. That's a minor quibble, and I recommend this without reservation.
