An ordinary fool isn't a faker; an honest fool is all right. But a dishonest fool is terrible!

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.

The game I play is a very interesting one. It's imagination, in a tight straightjacket.

Philosophers say a great deal about what is absolutely necessary for science, and it is always, so far as one can see, rather naive, and probably wrong.

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.

I have the advantage of having found out how hard it is to get to really know something. How careful you have to be about checking your experiments. How easy it is to make mistakes and fool yourself. I know what it means to know something.

So this piece of dirt waits four and a half billion years and evolves and changes, and now a strange creature stands here with instruments and talks to the strange creatures in the audience. What a wonderful world!
