All things are made of atoms-little particles that move around in perpetual motion, attracting each other when they are a little distance… — Richard P. Feynman Copy Share Image
Every instrument that has been designed to be sensitive enough to detect weak light has always ended up discovering that the same… — 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
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
The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge… — Richard P. Feynman Copy Share Image
You can’t say A is made of B or vice versa. All mass is interaction. — Richard P. Feynman Copy Share Image
No! Not for a second! I immediately began to think how this could have happened. And I realized that the clock was… — Richard P. Feynman Copy Share Image
John von Neumann gave me an interesting idea: that you don't have to be responsible for the world that you're in. So… — Richard P. Feynman Copy Share Image
If you can find any other view of the world which agrees over the entire range where things have already been observed,… — 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
There is nothing that living things do that cannot be understood from the point of view that they are made of atoms… — Richard P. Feynman Copy Share Image
There is no harm in doubt and skepticism, for it is through these that new discoveries are made. — Richard P. Feynman Copy Share Image
Science is a way to teach how something gets to be known, what is not known, to what extent things are known… — Richard P. Feynman Copy Share Image
All things are made of atoms - little particles that move around in perpetual motion, attracting each other when they are a… — 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
