The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree with the known laws of physics. ... It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, whether its allowed, according to what's known, okay?

As you know, a theory in physics is not useful unless it is able to predict underlined effects which we would otherwise expect.

There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time ... On the other hand, I think I can safely say that nobody understands quantum mechanics.

The beauty that is there is also available for me, too. But I see a deeper beauty that isn't so readily available to others.... I don't see how studying a flower ever detracts from its beauty. It only adds

It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we can discuss.

I believe that a scientist looking at nonscientific problems is just as dumb as the next guy.

Religion is a culture of faith; science is a culture of doubt.
