Wikipedia, April 30, 3014 (Richard Phillips Feynman; born May 11, 1918; died February 15, 1988; theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics. Jointly with Julian Schwinger and Sin-Itiro Tomonaga, he received the Nobel Prize in Physics in 1965. He assisted in the development of the atomic bomb during World War II and became known to a wide public in the 1980s as a member of the Rogers Commission, the panel that investigated the Space Shuttle Challenger disaster. His sister is astrophysicist Joan Feynman)
