Why do we do science? Beyond altruistic and self-aggrandizing motivations, many of our best scientists work long hours seeking the electric thrill that comes only from learning something that nobody knew before. The Pleasure of Finding Things Out, a collection of previously unpublished or difficult-to-find short works by maverick physicist Richard Feynman, takes its title from his own answer. From TV interview transcripts to his acceptance speech for the Nobel Prize, we see his quick, sharp wit, his devotion to his work, and his unwillingness to bow to social pressure or convention. It's no wonder he was only grudgingly admired by the establishment during his lifetime--read his "Minority Report to the Space Shuttle Challenger Inquiry" to see him blowing off political considerations as impediments to finding the truth.
