Feynman's major contribution was to [[quantum electrodynamics]]. He introduced the diagrams, now called [[Feynman diagrams]], which are used to describe the behaviour of systems of interacting particles. He was awarded a Nobel Prize for Physics in 1965. | Feynman's major contribution was to [[quantum electrodynamics]].
