Richard Phillips Feynman (1918–1988) was an American theoretical physicist known for major contributions to quantum electrodynamics, his development of Feynman diagrams, and his influential teaching and popular science work. He shared the 1965 Nobel Prize in Physics and also worked on the Manhattan Project and the Challenger disaster investigation.

Early life and education

Feynman was born in New York City and grew up in Queens. He studied at the Massachusetts Institute of Technology and received his Ph.D. from Princeton University in 1942.

Scientific contributions

His most famous scientific work was in quantum electrodynamics, where he helped create a more workable theory of how light and matter interact. He also developed Feynman diagrams, which became widely used in particle physics.

Teaching and public communication

Feynman became widely known for his lectures, teaching, and books on physics. He was admired for making difficult ideas accessible to general audiences and students.

Later life and legacy

Feynman worked at the California Institute of Technology and took part in the Challenger disaster investigation in the 1980s. He remains one of the most influential physicists of the 20th century.

Key facts

  • Feynman was a theoretical physicist whose work helped reformulate quantum electrodynamics.
