American physicist Richard Feynman was born #OTD in 1918.
He developed the Feynman diagrams, a pictorial representation of the mathematical expressions governing the behavior of subatomic particles, which provided a powerful tool for calculating complex interactions among particles. He received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga for their fundamental contributions to the development of quantum electrodynamics (QED).
