8251 | The logical space of reasons is a natural phenomenon, and it is the realm of freedom [McDowell] |
8128 | Representation must be propositional if it can give reasons and be epistemological [McDowell, by Burge] |
19092 | There is no pure Given, but it is cultured, rather than entirely relative [McDowell, by Macbeth] |
8253 | Sense impressions already have conceptual content [McDowell] |
8254 | Forming concepts by abstraction from the Given is private definition, which the Private Lang. Arg. attacks [McDowell] |
20624 | Work degrades into heat, but not vice versa [Close] |
20623 | First Law: energy can change form, but is conserved overall [Close] |
20625 | Third Law: total order and minimum entropy only occurs at absolute zero [Close] |
20622 | All motions are relative and ambiguous, but acceleration is the same in all inertial frames [Close] |
20628 | The electric and magnetic are tightly linked, and viewed according to your own motion [Close] |
20635 | The general relativity equations relate curvature in space-time to density of energy-momentum [Close] |
20627 | Electric fields have four basic laws (two by Gauss, one by Ampère, one by Faraday) [Close] |
20630 | Light isn't just emitted in quanta called photons - light is photons [Close] |
20637 | In general relativity the energy and momentum of photons subjects them to gravity [Close] |
20629 | Electro-magnetic waves travel at light speed - so light is electromagnetism! [Close] |
20632 | In QED, electro-magnetism exists in quantum states, emitting and absorbing electrons [Close] |
20642 | Photon exchange drives the electro-magnetic force [Close] |
20639 | Quantum fields contain continual rapid creation and disappearance [Close] |
20631 | Dirac showed how electrons conform to special relativity [Close] |
20641 | Electrons get their mass by interaction with the Higgs field [Close] |
20626 | Modern theories of matter are grounded in heat, work and energy [Close] |
20633 | The Higgs field is an electroweak plasma - but we don't know what stuff it consists of [Close] |
20640 | Space-time is indeterminate foam over short distances [Close] |
1515 | Pythagoreans believe it is absurd to seek for goodness anywhere except with the gods [Iamblichus] |
