The thing that doesn't fit is the thing that is most interesting.

One of the ways of stopping science would be only to do experiments in the region where you know the law. But experimenters search most diligently, and with the greatest effort, in exactly those places where it seems most likely that we can prove our theories wrong. In other words, we are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.

I don't feel frightened by not knowing things.

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.

The electron is a theory we use; it is so useful in understanding the way nature works that we can almost call it real.

Scientific knowledge is an enabling power to do either good or bad — but it does not carry instructions on how to use it.

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.
