Richard Feynman

I don't understand the world in the way that I think other people claim to understand it.

I was brought up to believe that the only way to really understand something is to build it.

I have a great deal of difficulty with the idea of 'truth' in the philosophical sense.

I think that when you're doing science, you're trying to find out something that nobody knows.

I'm not interested in science for the sake of science. I'm interested in science for the sake of understanding the world.

I was very surprised when I got the Nobel Prize. I didn't think I deserved it.

The purpose of computing is insight, not numbers.

I don't have to be consistent.

I think it's much more interesting to live with not knowing than to have answers that might be wrong.

I have often thought that if I were to be reborn, I'd like to be a biologist.

I don't like to be called 'Professor Feynman.' I like to be called 'Dick.'
