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
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

To decide upon the answer is not scientific. In order to make progress, one must leave the door to the unknown ajar… — 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
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
Computer science is not as old as physics; it lags by a couple of hundred years. However, this does not mean that… — Richard P. Feynman Copy Share Image
From the point of view of basic physics, the most interesting phenomena are, of course, in the new places, the places where… — 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
The correct statement of the laws of physics involves some very unfamiliar ideas which require advanced mathematics for their description. Therefore, one… — Richard P. Feynman Copy Share Image
“I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously… The principles of physics, as far… — Richard P. Feynman Copy Share Image
The drawing teacher has this problem of communicating how to draw by osmosis and not by instruction, while the physics teacher has… — Richard P. Feynman Copy Share Image
When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had… — Richard P. Feynman Copy Share Image
I don't like honors. I'm appreciated for the work that I did, and for people who appreciate it, and I notice that… — Richard P. Feynman Copy Share Image
What is necessary for 'the very existence of science,' and what the characteristics of nature are, are not to be determined by… — 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
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
“Out of the cradle onto the dry land here it is standing: atoms with consciousness; matter with curiosity. Stands at the sea… — Richard P. Feynman Copy Share Image
I am a successful lecturer in physics for popular audiences. The real entertainment gimmick is the excitement, drama and mystery of the… — Richard P. Feynman Copy Share Image
It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo… — 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
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
“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
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
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
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
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
It always seems odd to me that the fundamental laws of physics, when discovered, can appear in so many different forms that… — 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
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
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
Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning. — Richard P. Feynman Copy Share
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
“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
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
“There's a big difference between knowing the name of something and knowing something.” — Richard P. Feynman Copy Share
The fact that you are not sure means that it is possible that there is another way someday. — Richard P. Feynman Copy Share
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
Mathematics is not just a language. Mathematics is a language plus reasoning. — Richard P. Feynman Copy Share
