“The test of all knowledge is experiment. Experiment is the sole judge of scientific truth.”
Richard Feynman (verified)
The Feynman Lectures on Physics (Primary source)
A landmark three-volume series distilling undergraduate physics with unprecedented clarity and insight, these lectures transformed pedagogical tradition and remain essential reading for students and scientists worldwide decades after their 1960s publication.

“Each piece, or part, of the whole of nature is always merely an approximation to the complete truth, or the complete truth so far as we know it. In fact, everything we know is only some kind of approximation, because we know that we do not know all the laws as yet. Therefore, things must be learned only to be unlearned again or, more likely, to be corrected.
The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific truth.”

“I think that to keep trying new solutions is the way to do everything.”
— Richard Feynman (verified)“For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.”
— Richard Feynman (verified)“The prize is the pleasure of finding the thing out.”
— Richard Feynman (verified)“Looking back at the worst times, it always seems that they were times in which there were people who believed with absolute faith and absolute dogmatism in something.”

“How little we know of what there is to know. I wish that I were going to live a long time instead of going to die today because I have learned much about life in these four days; more, I think, than in all the other time. I’d like to be an old man and to really know. I wonder if you keep on learning or if there is only a certain amount each man can understand. I thought I knew about so many things that I know nothing of. I wish there was more time.”
— Ernest Hemingway (verified)“I had learned already never to empty the well of my writing.”
— Ernest Hemingway (verified)“Education is that which remains, if one has forgotten everything he learned in school.”
— Albert Einstein (verified)“The imagination of nature is far, far greater than the imagination of man.”
