Editor's Take:

Richard Feynman was one of the most brilliant and colourful physicists of the 20th century. As a young man he worked on the atomic bomb at Los Alamos, where he amused himself by cracking safes. He helped develop quantum electrodynamics, the theory of how light and matter interact. His simple Feynman diagrams changed how physicists calculate. He shared the Nobel Prize in Physics in 1965. On the Challenger disaster inquiry he showed, with a glass of iced water, why an O-ring failed. His lectures and books made physics feel like an adventure.
