Scientific knowledge is a body of statements of varying degrees of certainty -- some most unsure, some nearly sure, none absolutely certain. — Richard P. Feynman Copy Share Image
A very great deal more truth can become known than can be proven. — Richard P. Feynman Copy Share Image

The test of all knowledge is experiment. Experiment is the sole judge of scientific truth. — Richard P. Feynman Copy Share Image
I don't know what's the matter with people: they don't learn by understanding, they learn by some other way — by rote… — Richard P. Feynman Copy Share Image
“The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I… — 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
