Feynman started out at Los Alamos basically just crunching numbers computing things like what material would contain neutrons in the bomb itself, and the critical mass of the bombs. Feynman, being Feynman impressed the powers that be with his abilities, and soon moved up in the ranks. He ended up as the head of the theoretical division.

It was at Los Alamos that Feynman first began cracking safes. It started out as exercise to show his supervisors that the "safes" (really just ordinary filing cabinets with a jury padlock system on them) where not that secure. Soon he started doing it for fun and convenience (if the person who was responsible for the safe was not there, it was easier to crack the safe then to wait for the person to return).

While at Los Alamos Feynman also taught himself how to play the drums, a skill that he would later cultivate further. He was also, one of the few people to see the first nuclear explosion with the naked eye (he was behind a sheet of glass, so the UV rays were blocked). Sadly, during this time at Los Alamos, Feyman's first wife passed away from TB. .

After the war, Feynman accepted his first teaching position at Cornell University. It was during his time he that he was "inspired" by a spinning dinner plate that was tossed in the air, to eventually develop the theory that won him the Nobel Prize. Feynman only stayed at Cornell for several years, he later moved Caltech. By 1950 he was appointed the Richard Chace Tolman Professor of Theoretical Physics, the position he held for the rest of his life

It was during this time that Feynman accomplished some of his most important work. Mainly, completely theory of Quantum Electrodynamics: a theory that explained how electrons interact with each other. One thing, that I found interesting was, that while at Caltech Feynman would occasionally take sabbaticals, but not from all science, just from physics. So for a few months he would go and do research in another field such as biology.

Feynman had two children with his third wife Gweneth. His son Carl was born April 22nd 1961, and his daughter Michelle was born August 13th 1968.

In February of 1988, Richard Feynman passed away. He lost an eight-year battle with abdominal cancer. His last words were, "I'd hate to die twice. It's so boring."

The interesting things that Feynman did are too numerous to mention here. Here was an amazing man; there have been none like him since
