What is the fundamental hypothesis of science, the fundamental philosophy? We stated it in the first chapter: the sole test of the… — Richard P. Feynman Copy Share Image
It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who… — Richard P. Feynman Copy Share Image
The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it… — Richard P. Feynman Copy Share Image
A poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he… — Richard P. Feynman Copy Share Image
Poets say science takes away from the beauty of stars-mere globs of gas atoms. Nothing is "mere". I too see the stars… — 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
One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much. I… — Richard P. Feynman Copy Share Image
Scientific knowledge is an enabling power to do either good or bad — but it does not carry instructions on how to… — 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
Nature does not care what we call it, she just keeps on doing it. — 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
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
“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
