Feynman, FYN muhn, Richard Phillips (1918-1988), an American physicist, shared the 1965 Nobel Prize in physics with Julian S. Schwinger of the United States and Sin-Itiro Tomonaga of Japan. Working independently, the three men developed an improved theory of quantum electrodynamics (QED) in the late 1940's. QED is the study of the interaction of electrically charged subatomic particles (pieces of matter smaller than atoms) and electromagnetic radiation, such as light. Feynman also developed a method of using diagrams to picture elementary particle interactions. Feynman diagrams became a standard calculation tool in physics because they simplify the difficult calculations of a field of study called quantum field theory. See Quantum field theory.
