17596 | Coherence problems have positive and negative restraints; solutions maximise constraint satisfaction [Thagard] |
17597 | Coherence is explanatory, deductive, conceptual, analogical, perceptual, and deliberative [Thagard] |
17598 | Explanatory coherence needs symmetry,explanation,analogy,data priority, contradiction,competition,acceptance [Thagard] |
17602 | Verisimilitude comes from including more phenomena, and revealing what underlies [Thagard] |
17601 | Neither a priori rationalism nor sense data empiricism account for scientific knowledge [Thagard] |
17600 | Bayesian inference is forced to rely on approximations [Thagard] |
17064 | 1: Coherence is a symmetrical relation between two propositions [Thagard, by Smart] |
17065 | 2: An explanation must wholly cohere internally, and with the new fact [Thagard, by Smart] |
17066 | 3: If an analogous pair explain another analogous pair, then they all cohere [Thagard, by Smart] |
17067 | 4: For coherence, observation reports have a degree of intrinsic acceptability [Thagard, by Smart] |
17068 | 5: Contradictory propositions incohere [Thagard, by Smart] |
17069 | 6: A proposition's acceptability depends on its coherence with a system [Thagard, by Smart] |
17599 | The best theory has the highest subjective (Bayesian) probability? [Thagard] |
22745 | Pherecydes said the first principle and element is earth [Pherecydes, by Sext.Empiricus] |
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] |
5883 | Pherecydes was the first to say that the soul is eternal [Pherecydes, by Cicero] |
