28 Quotes & Sayings By Richard P Feynman

Richard Feynman was a theoretical physicist who won the Nobel Prize in Physics in 1965. He was known as a "compelling public speaker and a witty and jocular raconteur." His scientific achievements cover a wide range of fields, including quantum electrodynamics, particle physics, nanotechnology, and string theory. Born in New York City to a poor family, Feynman decided at an early age that he wanted to be an experimental physicist; he achieved this goal by developing his own style of physics research. He flew combat missions as an Air Force officer during World War II Read more

After the war he taught at Cornell University and later at Caltech, where he developed his famous teaching technique known as the "Feynman Lectures on Physics." These lectures were first published in book form in 1965; they are now considered required reading for students of all ages. The book that made him famous was Surely You're Joking, Mr. Feynman! (1985), which contains anecdotes about his life and career.

I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of great value to realize that we do not know the answers to different questions. This attitude of mind - this attitude of uncertainty - is vital to the scientist, and it is this attitude of mind which the student must first acquire. Richard P. Feynman
2
I thought one should have the attitude of 'What do you care what other people think! ' Richard P. Feynman
3
It is in the admission of ignorance and the admission of uncertainty that there is a hope for the continuous motion of human beings in some direction that doesn't get confined, permanently blocked, as it has so many times before in various periods in the history of man. Richard P. Feynman
4
Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea. Richard P. Feynman
5
There is a computer disease that anybody who works with computers knows about. It's a very serious disease and it interferes completely with the work. The trouble with computers is that you 'play' with them! Richard P. Feynman
6
Perhaps one day we will have machines that can cope with approximate task descriptions, but in the meantime, we have to be very prissy about how we tell computers to do things. Richard P. Feynman
7
Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry. Richard P. Feynman
8
Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic on which one has to walk in order not to make a mistake in predicting what will happen. The quantum mechanical and the relativity ideas are examples of this. Richard P. Feynman
9
See that the imagination of nature is far, far greater than the imagination of man. Richard P. Feynman
10
Reality must take precedence over public relations, for nature cannot be fooled. Richard P. Feynman
11
Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more? Richard P. Feynman
12
The most obvious characteristic of science is its application: the fact that, as a consequence of science, one has a power to do things. And the effect this power has had need hardly be mentioned. The whole industrial revolution would almost have been impossible without the development of science. Richard P. Feynman
13
The ideas associated with the problems of the development of science, as far as I can see by looking around me, are not of the kind that everyone appreciates. Richard P. Feynman
14
The drawing teacher has this problem of communicating how to draw by osmosis and not by instruction, while the physics teacher has the problem of always teaching techniques, rather than the spirit, of how to go about solving physical problems. Richard P. Feynman
15
I practiced drawing all the time and became very interested in it. If I was at a meeting that wasn't getting anywhere - like the one where Carl Rogers came to Caltech to discuss with us whether Caltech should develop a psychology department - I would draw the other people. Richard P. Feynman
16
Physics has a history of synthesizing many phenomena into a few theories. Richard P. Feynman
17
The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is. Richard P. Feynman
18
People are always asking for the latest developments in the unification of this theory with that theory, and they don't give us a chance to tell them anything about one of the theories that we know pretty well. They always want to know things that we don't know. Richard P. Feynman
19
Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man's struggle for good and evil seems inadequate. Richard P. Feynman
20
I don't know what's the matter with people: they don't learn by understanding; they learn by some other way - by rote, or something. Their knowledge is so fragile! Richard P. Feynman
21
If you realize all the time what's kind of wonderful - that is, if we expand our experience into wilder and wilder regions of experience - every once in a while, we have these integrations when everything's pulled together into a unification, in which it turns out to be simpler than it looked before. Richard P. Feynman
22
When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards. Richard P. Feynman
23
All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction. Richard P. Feynman
24
You're unlikely to discover something new without a lot of practice on old stuff, but further, you should get a heck of a lot of fun out of working out funny relations and interesting things. Richard P. Feynman
25
Until I began to learn to draw, I was never much interested in looking at art. Richard P. Feynman
26
For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled. Richard P. Feynman
27
I was born not knowing and have had only a little time to change that here and there. Richard P. Feynman
