Richard Feynman

We are at the very beginning of time for the human race. There is no reason to be discouraged, we have so much to do.

It is a great adventure to contemplate the universe, to think about the universe, and to try to understand it.

Why are there so many scientists who are religious? I don't know. But I think it's a kind of a schizophrenia.

I have a great respect for the past. If you want to do a good job, you've got to know what's been done before.

The highest forms of understanding we can achieve are always in the form of questions.

The world is a much more interesting place than any of the theories we have about it.

I don't know what's the matter with people, they don't learn by understanding; they learn by some other way—by rote or something. Their knowledge is so fragile!

The first principle is that you must not fool yourself — and you are the easiest person to fool.

Nature uses only the longest threads to weave her patterns, so each small piece of her fabric reveals the organization of the entire tapestry.

Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.

The pleasure of finding things out is the most important pleasure in life.

You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be.

If you think you understand quantum mechanics, you don't understand quantum mechanics.

The world is much more interesting than any one discipline.

There is no harm in doubt and skepticism, for it is through these that new discoveries are made.

Poets say science takes away from the beauty of the stars — mere globs of gas atoms. I too can see the stars on a desert night, and feel them. But do I see less or more?

The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.

Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter.

We are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.

The only way to have real success in science... is to describe the evidence very carefully without regard to the way you feel it should be.
