Feynman had a long and distinguished career as a theoretical physicist. He won the Nobel Prize in 1965
"... for fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles."
He is especially remembered among Caltech students for his humor, candor, and passion for drumming. He urged students, "Look at the ideas themselves and judge them directly. Do not accept them on the basis of authority. Question, question, question, especially your own ideas."
