Richard Phillips Feynman
Feynman, Richard Phillips (1918–88), U.S. physicist. He shared the 1965 Nobel Prize for physics for work on quantum electrodynamics. He worked on the development of the atomic bomb, developed a system of notation (the Feynman diagram) for recording and calculating subatomic reactions, and, with Murray Gell-Mann, explained the interactions of weak nuclear force.
