Feynman   (fīn'mən)  Pronunciation Key 
American physicist who developed the theory of quantum electrodynamics, laying the foundation for all other quantum field theories. His approach combined quantum mechanics and relativity theory, and exploited a method using diagrams of particle interactions to greatly simplify calculations. For this work he shared with American physicist Julian Schwinger and Japanese physicist Sin-Itiro Tomonaga the 1965 Nobel Prize for physics.
