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.”
Richard Feynman
