Biography

Richard Phillips Feynman was an American theoretical physicist. He shared the 1965 Nobel Prize in Physics with Julian Schwinger and Shin'ichirō Tomonaga "for their fundamental work in quantum electrodynamics (QED), with deep-ploughing consequences for the physics of elementary particles". He is also known for his work in the path integral formulation of quantum mechanics, the theory of the physics of the superfluidity of supercooled liquid helium, and the parton model. Feynman developed a pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams and is widely used.

Timeline

The story of Richard Feynman, told in moments.

1942 Event

Joins the Manhattan Project at Los Alamos. He's 24. His wife Arline is dying of tuberculosis in a sanatorium in Albuquerque. He visits her on weekends. She dies on June 16, 1945, a month before the Trinity test. He writes her a letter that he never sends. "I don't know how to tell you anything because there is no one to tell."

1948 Event

Develops the path integral formulation of quantum mechanics and the diagrams that bear his name. Feynman diagrams turn impossible calculations into pictures. They look like stick figures having a conversation. They reshape theoretical physics.

1965 Event

Wins the Nobel Prize in Physics for quantum electrodynamics, shared with Schwinger and Tomonaga. His lectures at Caltech, published as The Feynman Lectures on Physics, become the most widely used physics textbooks in the world. He tells students: "I think I can safely say that nobody understands quantum mechanics."

1986 Event

Serves on the Rogers Commission investigating the Challenger disaster. During a televised hearing, he drops a piece of O-ring rubber into a glass of ice water and squeezes it. It doesn't bounce back. That's the whole explanation. An engineer's demonstration worth more than a thousand pages of testimony.

1988 Death

Dies of cancer at 69 in Los Angeles. His last words: "I'd hate to die twice. It's so boring." He'd been diagnosed years earlier and refused further treatment. His desk blackboard reads "What I cannot create, I do not understand."
