The Man Who Drew the Universe

Richard Feynman won the Nobel Prize in Physics in 1965 for developing a visual language for describing how particles interact at the quantum level. He called the drawings Feynman diagrams. Physicists still use them. What looks like a doodle of wavy lines and arrows is actually a precise shorthand for calculating the probabilities of interactions between subatomic particles — photons, electrons, positrons — in quantum electrodynamics, the theory that describes how light and matter interact.
He also drove a van painted with Feynman diagrams on the side. It wasn't a statement. It was just his van. He thought the diagrams were beautiful and saw no reason they shouldn't be on a van.
Feynman spent part of the war years at Los Alamos working on the Manhattan Project, where he became known for cracking safes — not because he had lock-picking skills, but because he noticed that most people didn't change the default combinations. He kept meticulous notes on what combinations he'd tried, and opened safe after safe of classified documents, to the considerable irritation of the security team.
He played bongo drums seriously, gave lectures about the pleasure of finding things out, and wrote a series of physics textbooks that are still considered the best introduction to the subject ever written. He had a gift for explaining things at the exact level of complexity they required — no more, no less — and a deep impatience for anything that looked like rigour but wasn't.
He also served on the Rogers Commission investigating the Space Shuttle Challenger disaster, and famously demonstrated the failure of the O-ring seals by dropping one into a glass of ice water at a press conference. In the appendix to the commission report, he wrote: "For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled."
