Quotes by Richard Feynman

About Richard Feynman:

Richard Phillips Feynman was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal Physics World he was ranked as one of the ten greatest physicists of all time.

I... a universe of atoms, an atom in the universe.

Richard Feynman

A very great deal more truth can become known than can be proven.

Richard Feynman

Physicists like to think that all you have to do is say, these are the conditions, now what happens next?

Richard Feynman

I would rather have questions that can't be answered than answers that can't be questioned.

Richard Feynman

It doesn't matter how beautiful your theory is ... If it doesn't agree with experiment, it's wrong.

Richard Feynman

So my antagonist said, "Is it impossible that there are flying saucers? Can you prove that it's impossible?" "No", I said, "I can't prove it's impossible. It's just very unlikely". At that he said, "You are very unscientific. If you can't prove it im...

Philosophy of science is about as useful to scientists as ornithology is to birds.

Richard Feynman

Physics is like sex: sure, it may give some practical results, but that's not why we do it.

Richard Feynman

I have no responsibility to live up to what others expect of me. That's their mistake, not my failing.

Richard Feynman

[Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope you can accept nature as She is - absurd.

Richard Feynman

I learned very early the difference between knowing the name of something and knowing something.

Richard Feynman

If you thought you were trying to find out more about it because you're gonna get an answer to some deep philosophical question...you may be wrong! It may be that you can't get an answer to that particular question by finding out more about the chara...

Richard Feynman

If you thought that science was certain - well, that is just an error on your part.

Richard Feynman

Odiaría morir dos veces, sería tan aburrido!.

Richard Feynman

Science is a way of trying not to fool yourself. The principle is that you must not fool yourself, and you are the easiest person to fool.

Richard Feynman

You see, the chemists have a complicated way of counting: instead of saying "one, two, three, four, five protons," they say, "hydrogen, helium, lithium, beryllium, boron.

Richard Feynman

So I started to think: "How can that happen?"... So the guy says, "What are you doing? You come fix the radio, but you're only walking back and forth!" I say, "I'm thinking!

Richard Feynman

Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it.

Richard Feynman

The trouble with playing a trick on a highly intelligent man like Mr. Teller is that the time it takes him to figure out from the moment that he sees there is something wrong till he understands exactly what happened is too damn small to give you any...

Richard Feynman

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

Richard Feynman

I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alt...
