In fact the total amount that a physicist knows is very little. He has only to remember the rules to get him from one place to another and he is all right.

There is a computer disease that anybody who works with computers knows about. It's a very serious disease and it interferes completely with the work. The trouble with computers is that you 'play' with them!

Another thing I must point out is that you cannot prove a vague theory wrong.

I have a limited intelligence and I've used it in a particular direction.

I think we can safely assume that no one understands quantum mechanics.

Scientists are explorers. Philosophers are tourists.

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.
