The Pleasure of Finding Things Out.

Why do we do science? Beyond altruistic and self-aggrandizing motivations, many of the 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 The Pleasure of Finding Things Out, a collection of previously unpublished or difficult-to-find short works by maverick physicist Richard Feynman, takes its title from his own answer.
Feynman had a fantastic sense of humor, and his memoirs of his Manhattan Project days roil with fun despite his later misgivings about nuclear weapons.Though Feynman has been gone now for many years, his work lives on in quantum physics, computer design, and nanotechnology; like any great scientist, he asked more questions than he answered, to give future generations the pleasure of finding things out.
