As usual, nature's imagination far surpasses our own, as we have seen from the other theories which are subtle and deep. — Richard P. Feynman Copy Share Image
As you know, a theory in physics is not useful unless it is able to predict underlined effects which we would otherwise… — Richard P. Feynman Copy Share Image
It is going to be necessary that everything that happens in a finite volume of space and time would have to be… — Richard P. Feynman Copy Share Image
The situation in the sciences is this: A concept or an idea which cannot be measured or cannot be referred directly to… — Richard P. Feynman Copy Share Image
Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or… — Richard P. Feynman Copy Share Image
It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's… — Richard P. Feynman Copy Share Image
If there is something very slightly wrong in our definition of the theories, then the full mathematical rigor may convert these errors… — Richard P. Feynman Copy Share Image
People are always asking for the latest developments in the unification of this theory with that theory, and they don't give us… — Richard P. Feynman Copy Share Image
In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to… — Richard P. Feynman Copy Share Image
The electron is a theory. But the theory is so good we can almost consider them real. — Richard P. Feynman Copy Share Image
We've learned from experience that the truth will come out. Other experimenters will repeat your experiment and find out whether you were… — Richard P. Feynman Copy Share Image
Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the… — Richard P. Feynman Copy Share Image
The electron is a theory we use; it is so useful in understanding the way nature works that we can almost call… — Richard P. Feynman Copy Share Image
Another thing I must point out is that you cannot prove a vague theory wrong. — Richard P. Feynman Copy Share Image
There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there… — Richard P. Feynman Copy Share Image
The chance is high that the truth lies in the fashionable direction. But, on the off-chance that it is in another direction… — Richard P. Feynman Copy Share Image
Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so… — Richard P. Feynman Copy Share Image
One of the ways of stopping science would be only to do experiments in the region where you know the law. But… — Richard P. Feynman Copy Share Image
The shell game that we play ... is technically called 'renormalization'. But no matter how clever the word, it is still what… — Richard P. Feynman Copy Share Image
The only way to have real success in science, the field I'm familiar with, is to describe the evidence very carefully without… — Richard P. Feynman Copy Share Image
“If someone were to propose that the planets go around the sun because all planet matter has a kind of tendency for… — 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
