Richard Feynman Quotes
-
All the time you're saying to yourself, 'I could do that, but I won't,'--which is just another way of saying that you can't.
-
Doubt is clearly a value in science. It is important to doubt and that the doubt is not a fearful thing, but a thing of great value.
-
We cannot define anything precisely. If we attempt to, we get into the paralysis of thought that comes to philosophers, who sit opposite each other, one saying to the other, "You don't know what you are talking about!" The second one says, "What do you mean by know? What do you mean by talking? What do you mean by you?"
-
On the contrary, it's because somebody knows something about it that we can't talk about physics . It's the things that nobody knows anything about that we can discuss. We can talk about the weather; we can talk about social problems; we can talk about psychology; we can talk about international finance gold transfers we can't talk about, because those are understood so it's the subject that nobody knows anything about that we can all talk about!
-
I love only nature, and I hate mathematicians.
-
To develop working ideas efficiently, I try to fail as fast as I can.
-
Physicists like to think that all you have to do is say, these are the conditions, now what happens next?
-
Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.
-
We need to teach how doubt is not to be feared but welcomed. It's OK to say, "I don't know."
-
Scientists are explorers. Philosophers are tourists.
-
Agnostic for me would be trying to weasel out and sound a little nicer than I am about this.
-
The chance is high that the truth lies in the fashionable direction. But, on the off-chance that it is in another direction - a direction obvious from an unfashionable view of field theory - who will find it? Only someone who has sacrificed himself by teaching himself quantum electrodynamics from a peculiar and unusual point of view; one that he may have to invent for himself.
-
Ordinary fools are all right; you can talk to them, and try to help them out. But pompous fools-guys who are fools and are covering it all over and impressing people as to how wonderful they are with all this hocus pocus-THAT, I CANNOT STAND! An ordinary fool isn't a faker; an honest fool is all right. But a dishonest fool is terrible!
-
We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
-
A philosopher once said, 'It is necessary for the very existence of science that the same conditions always produce the same results.' Well, they don't!
-
You can always recognize truth by its beauty and simplicity.
-
It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly.
-
When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do some kind of dance, the net result of which is the same as if the photon hit only on the surface.
-
Phenomena complex-laws simple....Know what to leave out.
-
It's amazing how many people even today use a computer to do something you can do with a pencil and paper in less time.
-
Physics is not the most important thing. Love is.
-
It is not unscientific to make a guess, although many people who are not in science think it is.
-
I don't have to be good because they think I'm going to be good.
-
The theoretical broadening which comes from having many humanities subjects on the campus is offset by the general dopiness of the people who study these things.
