"I asked him once, 'How do you tell when a mathematical argument is correct?' He said, 'If it's beautiful, it's correct.'"

"It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong."

"I don't think there's any such thing as a 'best' way to do anything. There's just what works."

"I don't like to be called a genius. I just like to think."
