1635 | Mathematics reduces to set theory (which is a bit vague and unobvious), but not to logic proper [Quine] |
19696 | There are reasons 'for which' a belief is held, reasons 'why' it is believed, and reasons 'to' believe it [Neta] |
19697 | The basing relation of a reason to a belief should both support and explain the belief [Neta] |
7627 | You can't reduce epistemology to psychology, because that presupposes epistemology [Maund on Quine] |
8871 | We should abandon a search for justification or foundations, and focus on how knowledge is acquired [Quine, by Davidson] |
8826 | If we abandon justification and normativity in epistemology, we must also abandon knowledge [Kim on Quine] |
8827 | Without normativity, naturalized epistemology isn't even about beliefs [Kim on Quine] |
8899 | Epistemology is a part of psychology, studying how our theories relate to our evidence [Quine] |
8898 | Inculcations of meanings of words rests ultimately on sensory evidence [Quine] |
8900 | In observation sentences, we could substitute community acceptance for analyticity [Quine] |
21202 | The strong force has a considerably greater range than the weak force [Martin,BR] |
21211 | If an expected reaction does not occur, that implies a conservation law [Martin,BR] |
21209 | Electron emit and reabsorb photons, which create and reabsorb virtual electrons and positrons [Martin,BR] |
21201 | A 'field' is just a region to which points can be assigned in space and time [Martin,BR] |
21212 | The Higgs field, unlike others, has a nozero value in a state without particles [Martin,BR] |
21205 | Many physicists believe particles have further structure, if only we could see it [Martin,BR] |
21203 | Uncertainty allows very brief violations of energy conservation - even shorter with higher energies [Martin,BR] |
21207 | The Exclusion Principle says no two fermions occupy the same state, with the same numbers [Martin,BR] |
21204 | The standard model combines theories of strong interaction, and electromagnetic and weak interaction [Martin,BR] |
21208 | Eletrons don't literally 'spin', because they are point-like [Martin,BR] |
21210 | Virtual particles surround any charged particle [Martin,BR] |
21206 | The properties of a particle are determined by its quantum numbers and its mass [Martin,BR] |
21213 | String theory only has one free parameter (tension) - unlike the standard model with 19 [Martin,BR] |
21200 | An 'element' is what cannot be decomposed by chemistry [Martin,BR] |
