Richard P. Feynman (1918-88) was one of this century's most brilliant and original thinkers. He taught at Cornell and the California Institute of Technology and received the Nobel Prize in Physics for his work in quantum electrodynamics. Books by Feynman in Penguin include THE CHARACTER OF PHYSICAL LAW (1965), QED (1985), the bestselling THE MEANING OF IT ALL(1998) and SIX EASY PIECES (1998).
