|Knowledge: Knowledge is a conscious relationship to sentences or propositions, which legitimately attributes to them truth or falsehood. What is known is true. Conversely, it does not apply that everything that is true is also known. See also knowledge how, propositional knowledge, realism, abilities, competence, truth, facts, situations, language, certainty, beliefs, omniscience, logical knowledge, reliability_____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |
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.
