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
There is nothing in biology yet found that indicates the inevitability of death. This suggests to me that it is not at… — Richard P. Feynman Copy Share Image
It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate… — 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
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
We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without… — Richard P. Feynman Copy Share Image
When a Caltech student asked the eminent cosmologist Michael Turner what his "bias" was in favoring one or another particle as a… — Richard P. Feynman Copy Share Image
If the professors of English will complain to me that the students who come to the universities, after all those years of… — Richard P. Feynman Copy Share Image
Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if… — Richard P. Feynman Copy Share Image
I have to keep going to find out ultimately what is the matter with it in the end. — Richard P. Feynman Copy Share Image
To guess what to keep and what to throw away takes considerable skill. Actually it is probably merely a matter of luck,… — Richard P. Feynman Copy Share Image
Looking back at the worst times, it always seems that they were times in which there were people who believed with absolute… — Richard P. Feynman Copy Share Image
It does not matter who you are, or how smart you are, or what title you have, or how many of you… — 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
I learned from her that every woman is worried about her looks, no matter how beautiful she is. — Richard P. Feynman Copy Share Image
Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter. — Richard P. Feynman Copy Share Image
Another of the qualities of science is that it teaches the value of rational thought, as well as the importance of freedom… — Richard P. Feynman Copy Share Image
All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in… — Richard P. Feynman Copy Share Image
'Conservation' (the conservation law) means this ... that there is a number, which you can calculate, at one moment-and as nature undergoes… — Richard P. Feynman Copy Share Image
Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter.… — 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
