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
We cannot define anything precisely. If we attempt to, we get into the paralysis of thought that comes to philosophers, who sit… — 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
In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known"… — Richard P. Feynman Copy Share Image
[When a young person loses faith in his religion because he begins to study science and its methodology] it isn't that [through… — 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
