Born in 1918 in Queens, New York, Richard Phillips Feynman showed early genius in mathematics and tinkering, fixing radios and building home laboratories. At Princeton he worked on the Manhattan Project under Hans Bethe, developing calculation methods while witnessing the birth of the atomic age at Los Alamos.

After the war, Feynman revolutionized theoretical physics with his path-integral formulation and Feynman diagrams, tools that simplified quantum electrodynamics and earned him the Nobel Prize alongside Julian Schwinger and Sin-Itiro Tomonaga. At Caltech he delivered undergraduate lectures later published as *The Feynman Lectures on Physics*, still widely used decades later.

Beyond equations, Feynman pursued safecracking at Los Alamos, bongo drumming, and painting. His plain-spoken skepticism shone during the 1986 Challenger inquiry, when he demonstrated O-ring failure in ice water on television. He died in 1988, remembered as a physicist who insisted that if you cannot explain something simply, you do not yet understand it.

1. 1918

   Born in Queens, New York

   Raised by immigrant parents who encouraged curiosity; taught himself advanced mathematics as a teenager.

2. 1942

   Joins Manhattan Project

   Recruited to Los Alamos, where he developed calculation shortcuts and became known for safecracking and pranks.

3. 1965

   Nobel Prize in Physics

   Honored for fundamental work in quantum electrodynamics alongside Schwinger and Tomonaga.

4. 1986

   Rogers Commission Testimony

   Demonstrated shuttle O-ring vulnerability on television, cutting through bureaucratic obfuscation.

5. 1988

   Death from Cancer

   Died in Los Angeles; his memoirs and lectures continue to inspire scientists and general readers alike.
