  1. I love listening to Feynman. Such a brilliant guy, and such a great teacher. You want to know how quantum mechanics works, but you don't have the math background? Feynman will explain it.

  2. @ Nathaniel: Yeah, he's good at explaining things in simple terms.


Thanks for taking the time to comment.
