19558 | Our own intuitions about whether we know tend to vacillate [Cohen,S] |
19561 | We shouldn't jump too quickly to a contextualist account of claims to know [Cohen,S] |
19563 | The context sensitivity of knowledge derives from its justification [Cohen,S] |
19560 | Contextualism is good because it allows knowledge, but bad because 'knowing' is less valued [Cohen,S] |
12893 | Contextualism says sceptical arguments are true, relative to their strict context [Cohen,S] |
12896 | Knowledge is context-sensitive, because justification is [Cohen,S] |
12894 | There aren't invariant high standards for knowledge, because even those can be raised [Cohen,S] |
19559 | Contextualists slightly concede scepticism, but only in extremely strict contexts [Cohen,S] |
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] |
20642 | Photon exchange drives the electro-magnetic force [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] |

20639 | Quantum fields contain continual rapid creation and disappearance [Close] |
20641 | Electrons get their mass by interaction with the Higgs field [Close] |
20631 | Dirac showed how electrons conform to special relativity [Close] |
20626 | Modern theories of matter are grounded in heat, work and energy [Close] |
