Summary

American theoretical physicist who developed quantum electrodynamics (QED), the path integral formulation of quantum mechanics, and Feynman diagrams — and was the most celebrated physics teacher of the 20th century.

Core Contribution

QED (quantum electrodynamics): the most precisely tested theory in physics — describes the interaction of light and matter to incredible precision. Path integral formulation: quantum amplitudes sum over all possible paths. Feynman Lectures on Physics: the canonical modern introduction to physics.

Key Spikes & Highlights

Path integral: instead of a particle taking a definite path, it takes every possible path simultaneously, each contributing a quantum amplitude — their interference produces the observed behavior. This is not a metaphor but a calculational method used by every particle physicist.
Was the only person who could understand the bongo drums at Caltech faculty parties and the only Nobel laureate to be part of the Rogers Commission investigating the Challenger disaster — he demonstrated O-ring failure live on national television with a glass of ice water.
Refused to join the National Academy of Sciences after being elected, saying the committee work was not worth the honor.
