Richard Phillips Feynman was an American theoretical physicist and Nobel Prize winner who made significant contributions to quantum mechanics, quantum electrodynamics, and particle physics. He's known for his work on the Manhattan Project, developing Feynman diagrams, and explaining the interactions between light and matter. While studying for his PhD, Feynman participated in the Manhattan Project and helped develop the atomic bomb. For contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga.
