“I've always been rather very one-sided about the science, and when I was younger, I concentrated almost all my effort on it.… — Richard P. Feynman Copy Share Image
To decide upon the answer is not scientific. In order to make progress, one must leave the door to the unknown ajar… — 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
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
I think it's much more interesting to live not knowing than to have answers which might be wrong. — Richard P. Feynman Copy Share Image
A scientist is never certain. ... We absolutely must leave room for doubt or there is no progress and there is no learning. — Richard P. Feynman Copy Share Image
Outside of their particular area of expertise scientists are just as dumb as the next person. — Richard P. Feynman Copy Share Image
This attitude of mind - this attitude of uncertainty - is vital to the scientist, and it is this attitude of mind… — Richard P. Feynman Copy Share Image
We decided that 'trivial' means 'proved'. So we joked with the mathematicians: We have a new theorem- that mathematicians can prove only… — Richard P. Feynman Copy Share Image
I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of… — Richard P. Feynman Copy Share Image
I don't feel frightened by not knowing things, by being lost in a mysterious universe without any purpose, which is the way… — Richard P. Feynman Copy Share Image
The whole question of imagination in science is often misunderstood by people in other disciplines. ... They overlook the fact that whatever… — Richard P. Feynman Copy Share Image
If I say [electrons] behave like particles I give the wrong impression; also if I say they behave like waves. They behave… — 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
Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so… — Richard P. Feynman Copy Share Image
Our poets do not write about it; our artists do not try to portray this remarkable thing. I don't know why. Is… — Richard P. Feynman Copy Share Image
You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely… — 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
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
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
Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning. — Richard P. Feynman Copy Share
