Richard Feynman

Richard Feynman shared the 1965 Physics prize for his work on quantum electrodynamics (QED), which describes how light and matter interact with a precision of one part in 10 trillion—equivalent to measuring the distance from New York to Los Angeles within one hair’s width. His path integral formulation and Feynman diagrams revolutionized theoretical physics, offering a visualization tool used in over 99% of quantum calculations today.
