Richard Feynman

The more you learn, the more you realize how much you don't know.

If we are going to live in a scientific age, we must understand what science is and is not.

The real problem in speech is not to persuade, but to listen.

I have a friend who's an artist and has sometimes taken a view which I don't agree with very well. He'll hold up a flower and say, 'Look how beautiful it is,' and I'll agree, 'Yes, it is beautiful.' He says, 'As an artist I can see how beautiful this is, but you as a scientist take this all apart and it becomes a dull thing.' And I think that he's kind of nutty. ... I can appreciate the beauty of a flower as well as he can, and at the same time I see much more in the flower than he sees.

There is no such thing as a 'common man.'

I don't believe I'm a deep thinker. I'm a very shallow thinker. I think about things in a very simple way.

The only way to do something in a new way is to do it wrong the first time.

You can't just say, 'I'm going to be a scientist.' You have to be interested in something.

I have often thought that if there is any hell, it is a place where you are not allowed to ask questions.

We are at the very beginning of time for the human race. There is no reason to believe that we will not have a longer future ahead of us than we have had a past.

If we are going to be scientific, we must work only from experiment and observation, and not from what we think is beautiful or what we think is right.

I don't believe in the idea that there are a few special people who can understand it and the rest of the world is left out. I think that's a terrible idea.

The truth is, I don't know anything.

The only way to do science is to ask questions and to be willing to be wrong.

To understand the world, you must be willing to get your hands dirty.

The great thing about science is that it's true, whether or not you believe in it.

The game is to try to figure out how nature works.

If you're going to be a scientist, you have to be willing to admit you're wrong.

I don't feel that I'm a scientist. I feel that I'm a person who is trying to understand the world.

The only way to learn is by doing.
