We are very lucky to be living in an age in which we are still making discoveries. It is like the discovery… — Richard P. Feynman Copy Share Image
The fundamental principle of science, the definition almost, is this: the sole test of the validity of any idea is experiment. — Richard P. Feynman Copy Share Image
There’s so much distance between the fundamental rules and the final phenomenon, that it’s almost unbelievable that the final variety of phenomenon… — Richard P. Feynman Copy Share Image
In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to… — Richard P. Feynman Copy Share Image
So far as we know, all the fundamental laws of physics, like Newton's equations, are reversible. — 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

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
