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

I don't believe I can really do without teaching. The reason is, I have to have something so that when I don't have any ideas and I'm not getting anywhere, I can say to myself, "At least I'm living; at least I'm doing something. I'm making some contribution." It's just psychological.

For those who want some proof that physicists are human, the proof is in the idiocy of all the different units which they use for measuring energy.

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.

What would happen if we could arrange the atoms one by one the way we want them?

I don't think that the laws can be considered to be like God because they have been figured out.

To develop working ideas efficiently, I try to fail as fast as I can.
