If all of mathematics disappeared, physics would be set back by exactly one week. — Richard P. Feynman Copy Share Image
Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena… — Richard P. Feynman Copy Share Image
It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the… — Richard P. Feynman Copy Share Image
In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known"… — Richard P. Feynman Copy Share Image
Any schemes - such as 'think of symmetry laws', or 'put the information in mathematical form', or 'guess equations'- are known to… — Richard P. Feynman Copy Share Image
We're always, by the way, in fundamental physics, always trying to investigate those things in which we don't understand the conclusions. After… — Richard P. Feynman Copy Share Image
I think, however, that there isn't any solution to this problem of education other than to realize that the best teaching can… — Richard P. Feynman Copy Share Image
Often one postulates that a priori, all states are equally probable. This is not true in the world as we see it.… — Richard P. Feynman Copy Share Image
“CURIOSITY DEMANDS THAT WE ASK QUESTIONS, THAT WE TRY TO PUT THINGS TOGETHER AND TRY TO UNDERSTAND THIS MULTITUDE OF ASPECTS AS… — Richard P. Feynman Copy Share Image
We get the exciting result that the total energy of the universe is zero. Why this should be so is one of… — Richard P. Feynman Copy Share Image
Turbulence is the most important unsolved problem of classical physics. — Richard P. Feynman Copy Share Image
Physics is like sex: sure, it may give some practical results, but that's not why we do it. — Richard P. Feynman Copy Share Image
There is nothing that living things do that cannot be understood from the point of view that they are made of atoms… — Richard P. Feynman Copy Share Image
The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree… — Richard P. Feynman Copy Share Image
Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and… — Richard P. Feynman Copy Share Image
“There was an interesting early relationship between physics and biology in which biology helped physics in the discovery of the conservation of… — Richard P. Feynman Copy Share Image
As revealed by physics, the truth is so remarkable, so amazing! — Richard P. Feynman Copy Share Image
We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much… — Richard P. Feynman Copy Share Image
I think equation guessing might be the best method to proceed to obtain the laws for the part of physics which is… — Richard P. Feynman Copy Share Image
What I am going to tell you about is what we teach our physics students in the third or fourth year of… — Richard P. Feynman Copy Share Image
“I can live with doubt and uncertainty and not knowing. I think it's much more interesting to live not knowing than to… — Richard P. Feynman Copy Share Image
It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we… — Richard P. Feynman Copy Share Image
The present situation in physics is as if we know chess, but we don't know one or two rules. — Richard P. Feynman Copy Share Image
Today we say that the law of relativity is supposed to be true at all energies, but someday somebody may come along… — Richard P. Feynman Copy Share Image
“Philosophers have said before that one of the fundamental requisites of science is that whenever you set up the same conditions, the same thing… — Richard P. Feynman Copy Share Image
My rule is, when you are unhappy, think about it. But when you're happy, don't. Why spoil it? You're probably happy for some ridiculous… — Richard P. Feynman Copy Share Image
Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic… — Richard P. Feynman Copy Share Image
Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning. — Richard P. Feynman Copy Share Image
It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions. — Richard P. Feynman Copy Share Image
“There was a Princess Somebody of Denmark sitting at a table with a number of people around her, and I saw an empty chair… — Richard P. Feynman Copy Share Image
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. — Richard P. Feynman Copy Share Image
“There's a big difference between knowing the name of something and knowing something.” — Richard P. Feynman Copy Share Image
The fact that you are not sure means that it is possible that there is another way someday. — Richard P. Feynman Copy Share Image
One cannot understand... the universality of laws of nature, the relationship of things, without an understanding of mathematics. There is no other way to… — Richard P. Feynman Copy Share Image
