Intro

Richard Feynman (1918–1988) was a Nobel Prize-winning theoretical physicist who made fundamental contributions to quantum electrodynamics, particle physics, and the physics of superfluidity. But perhaps more than his scientific achievements, Feynman is remembered for his extraordinary ability to explain complex scientific concepts with clarity, humor, and infectious enthusiasm.

He was a professor at Caltech, worked on the Manhattan Project, played the bongos, cracked safes, and was one of the few scientists who could make quantum mechanics feel accessible to everyone. His "Feynman Lectures on Physics" remain essential reading for physics students worldwide.

Famous Quotes

"The first principle is that you must not fool yourself—and you are the easiest person to fool."

"I would rather have questions that can't be answered than answers that can't be questioned."

"I learned very early the difference between knowing the name of something and knowing something."

The Challenger Investigation

In 1986, Feynman served on the Rogers Commission investigating the Space Shuttle Challenger disaster. In a famous live demonstration, he dropped an O-ring into ice water, proving that the rubber seals lost flexibility in cold weather—the root cause of the explosion. His appendix to the commission report criticized NASA's risk assessment.
