7260 If there are intuited moral facts, why should we care about them? [Dancy,J]
7261 Internalists say that moral intuitions are motivating; externalist say a desire is also needed [Dancy,J]
7262 Obviously judging an action as wrong gives us a reason not to do it [Dancy,J]
7265 Moral facts are not perceived facts, but perceived reasons for judgements [Dancy,J]

21202 The strong force has a considerably greater range than the weak force [Martin,BR]
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / c. Conservation of energy
21211 If an expected reaction does not occur, that implies a conservation law [Martin,BR]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / a. Electrodynamics
21209 Electron emit and reabsorb photons, which create and reabsorb virtual electrons and positrons [Martin,BR]
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields
