I think I can safely say that nobody understands Quantum Mechanics. — Richard P. Feynman Copy Share Image
The Quantum Universe has a quotation from me in every chapter - but it's a damn good book anyway. — Richard P. Feynman Copy Share Image
When the problem [quantum chromodynamics] is finally solved, it will all be by imagination. Then there will be some big thing about… — Richard P. Feynman Copy Share Image
Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by… — Richard P. Feynman Copy Share Image
With the exception of gravitation and radioactivity, all of the phenomena known to physicists and chemists in 1911 have their ultimate explanation… — 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… — Richard P. Feynman Copy Share Image
If I say [electrons] behave like particles I give the wrong impression; also if I say they behave like waves. They behave… — Richard P. Feynman Copy Share Image
I think we can safely assume that no one understands quantum mechanics. — Richard P. Feynman Copy Share Image
If you think you understand quantum mechanics, you don't understand quantum mechanics. — Richard P. Feynman Copy Share Image
The 'paradox' is only a conflict between reality and your feeling of what reality 'ought to be. — Richard P. Feynman Copy Share Image
A philosopher once said, 'It is necessary for the very existence of science that the same conditions always produce the same results.'… — 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
[Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So… — Richard P. Feynman Copy Share Image
You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there's no… — Richard P. Feynman Copy Share Image
It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger… — Richard P. Feynman Copy Share Image
There were several possible solutions of the difficulty of classical electrodynamics, any one of which might serve as a good starting point… — Richard P. Feynman Copy Share Image
I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this,… — Richard P. Feynman Copy Share Image
Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success.… — 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
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
“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
