| 14255 | We understand things through their dependency relations [Fine,K] |
| 14250 | Metaphysics deals with the existence of things and with the nature of things [Fine,K] |
| 5035 | The two basics of reasoning are contradiction and sufficient reason [Leibniz] |
| 14259 | Maybe two objects might require simultaneous real definitions, as with two simultaneous terms [Fine,K] |
| 14253 | An object's 'being' isn't existence; there's more to an object than existence, and its nature doesn't include existence [Fine,K] |
| 14261 | There is 'weak' dependence in one definition, and 'strong' dependence in all the definitions [Fine,K] |
| 14251 | A natural modal account of dependence says x depends on y if y must exist when x does [Fine,K] |
| 14257 | An object depends on another if the second cannot be eliminated from the first's definition [Fine,K] |
| 14254 | Dependency is the real counterpart of one term defining another [Fine,K] |
| 14252 | We should understand identity in terms of the propositions it renders true [Fine,K] |
| 14256 | How do we distinguish basic from derived esssences? [Fine,K] |
| 14258 | Maybe some things have essential relationships as well as essential properties [Fine,K] |
| 14260 | An object only essentially has a property if that property follows from every definition of the object [Fine,K] |
| 5038 | Assume that mind and body follow their own laws, but God has harmonised them [Leibniz] |
| 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] |
| 5037 | God doesn't decide that Adam will sin, but that sinful Adam's existence is to be preferred [Leibniz] |
