2017 | Theories of Everything |
3 'Arrow' | p.30 | 20625 | Third Law: total order and minimum entropy only occurs at absolute zero |
3 'Arrow' | p.32 | 20626 | Modern theories of matter are grounded in heat, work and energy |
3 'Light!' | p.34 | 20627 | Electric fields have four basic laws (two by Gauss, one by Ampère, one by Faraday) |
3 'Light!' | p.36 | 20628 | The electric and magnetic are tightly linked, and viewed according to your own motion |
3 'Light!' | p.39 | 20629 | Electro-magnetic waves travel at light speed - so light is electromagnetism! |
3 'Light!' | p.48 | 20630 | Light isn't just emitted in quanta called photons - light is photons |
3 'Light!' | p.51 | 20631 | Dirac showed how electrons conform to special relativity |
3 'Light!' | p.56 | 20632 | In QED, electro-magnetism exists in quantum states, emitting and absorbing electrons |
3 'Newton's' | p.21 | 20622 | All motions are relative and ambiguous, but acceleration is the same in all inertial frames |
3 'Perpetual' | p.27 | 20623 | First Law: energy can change form, but is conserved overall |
3 'Perpetual' | p.28 | 20624 | Work degrades into heat, but not vice versa |
4 'Higgs' | p.78 | 20633 | The Higgs field is an electroweak plasma - but we don't know what stuff it consists of |
5 'Cosmological' | p.101 | 20638 | General relativity assumes laws of nature are the same in all frames of reference |
5 'Gravity' | p.91 | 20634 | General Relativity says there is no absolute force or acceleration |
5 'Gravity' | p.96 | 20635 | The general relativity equations relate curvature in space-time to density of energy-momentum |
5 'Gravity' | p.97 | 20636 | Newton is a special case of Einstein's general theory, with an infinite speed of light |
5 'Planck' | p.99 | 20637 | In general relativity the energy and momentum of photons subjects them to gravity |
