Richard Feynman Quotes
-
If science is to progress, what we need is the ability to experiment, honesty in reporting results—the results must be reported without somebody saying what they would like the results to have been—and finally—an important thing—the intelligence to interpret the results.
-
You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing.
-
I don't believe I can really do without teaching. The reason is, I have to have something so that when I don't have any ideas and I'm not getting anywhere, I can say to myself, "At least I'm living; at least I'm doing something. I'm making some contribution." It's just psychological.
-
A scientist is never certain. ... We absolutely must leave room for doubt or there is no progress and there is no learning.
-
One of the ways of stopping science would be only to do experiments in the region where you know the law. But experimenters search most diligently, and with the greatest effort, in exactly those places where it seems most likely that we can prove our theories wrong. In other words, we are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.
-
If you can find any other view of the world which agrees over the entire range where things have already been observed, but disagrees somewhere else, you have made a great discovery.
-
One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much. I love only nature, and I hate mathematicians.
-
Learn what the rest of the world is like. The variety is worthwhile.
-
Don't worry about anything. Go out and have a good time.
-
Ordinary fools are all right; you can talk to them, and try to help them out. But pompous fools-guys who are fools and are covering it all over and impressing people as to how wonderful they are with all this hocus pocus-THAT, I CANNOT STAND! An ordinary fool isn't a faker; an honest fool is all right. But a dishonest fool is terrible!
-
It does not matter who you are, or how smart you are, or what title you have, or how many of you there are, and certainly not how many papers your side has published, if your prediction is wrong then your hypothesis is wrong. Period.
-
I think I can safely say that nobody understands Quantum Mechanics.
-
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.
-
People who wish to analyze nature without using mathematics must settle for a reduced understanding.
-
Do not read so much, look about you and think of what you see there.
-
I'm going to play with physics, whenever I want to, without worrying about any importance whatsoever.
-
When you get as old as I am, you start to realize that you've told most of the good stuff you know to other people anyway.
-
Work as hard and as much as you want to on the things you like to do the best.
-
In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known" with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities.
-
What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.
-
Everything is made of atoms.
-
Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it
-
There's plenty of room at the bottom.
-
Mathematics is not just a language. Mathematics is a language plus reasoning.
