Richard Feynman Cracked Atomic Safes

American physicist Richard Feynman taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus by the age of 15. During World War II, he later worked at Los Alamos on the Manhattan Project, where scientists handled atomic secrets under tight security. While there, Feynman jokingly cracked safes by trying numbers he thought a physicist might use.
