Richard Feynman was one of the most productive and famous physicists of the 20th century. Especially in relation to Manhattan Project - a very secret effort made by the United States to make atomic bombs.

However, he is also a fad and has a reputation as a troublemaker. When bored with the project he was working on at Los Amos, Feynman reportedly spent his spare time unloading locks and breaking into people's safes - not his money or property, but to show how easily a system was hacked.

And, that's not just the adventure. While developing the theory of quantum electrodynamics - which led him to the Nobel prize - he reportedly often mingled with Las Vegas dance girls, had time to study until he became a Maya language expert, learned Tuva's distinctive throat singing, and explained how the rubber seal of the O ring (O- ring) triggered the Challenger spacecraft explosion in 1986.
