We are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.

If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives.

We are lucky to live in an age in which we are still making discoveries.

Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter.

But see that the imagination of nature is far, far greater than the imagination of man.

You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there's no real problem. It has not yet become obvious to me that there's no real problem. I cannot define the real problem, therefore I suspect there's no real problem, but I'm not sure there's no real problem.

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics.
