As part of a celebration of the legacy of Richard Feynman at Caltech this week, Bill Gates contributed a video about what he learned from Feynman.
In that video, I especially love the way Feynman explains how fire works. He takes such obvious delight in knowledge — you can see his face light up. And he makes it so clear that anyone can understand it.
I love that video as well...just watched it again and it's so so good.
