I don't know very much about Richard Feynman, though I've read a book or two (or part of a book) and I surely can't comprehend half the physics he's on about, but he's a great figure to learn from, especially in videos like this where you can see the endless wonder of the natural world animating his face.
He looks and sounds like a lot of the older born&bred New York guys I work with. For some reason I'm always charmed by that accent. And the fact that Feynman's older in these videos makes him seem loving and avuncular. Dude's adorable, what can I say? Easy to listen to people like this. Watch them all, go ahead.
