Richard Feynman

Richard Phillips Feynman (1918–1988) was an American theoretical physicist who spent the latter part of his career at the California Institute of Technology. He is best known for his work in quantum electrodynamics, for which he shared the 1965 Nobel Prize in Physics, and for inventing Feynman diagrams, a pictorial representation of subatomic particle interactions. He was also widely recognized as an exceptionally effective and clear expositor of physics, both through his legendary Caltech lecture series and his popular science writings.
