Principle of the Shortest Time/Fermat/"Knowledge"/Feynman: how does light know which path to take?
Important: there is an area near the optimum point where, in the first approximation, there is no significant change in time. But there is in second order.
Feynman: this is not about causality!
In fact, the light decides! It practically smells the right path.
This is related to the wavelength.
Knowledge/Saying/Language/Uncertainty Principle/Feynman: that we cannot precisely measure place and impulse does not mean a priori that we cannot talk about it. It just means we do not need to talk about it!
Knowledge/Atoms/Atomism/Feynman: if all physical knowledge were destroyed and only one insight was preserved, the thesis that everything is made of atoms would be the most important one._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
