7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
17486 Supervenience is simply modally robust property co-variance
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
17481 Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa
26. Natural Theory / B. Natural Kinds / 2. Defining Kinds
17478 Maybe two kinds are the same if there is no change of entropy on isothermal mixing
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
17479 The nature of an element must survive chemical change, so it is the nucleus, not the electrons
17484 Maybe the nature of water is macroscopic, and not in the microstructure
17485 Maybe water is the smallest part of it that still counts as water (which is H2O molecules)
27. Natural Reality / F. Chemistry / 1. Chemistry
17483 Water continuously changes, with new groupings of molecules
17482 Compounds can differ with the same collection of atoms, so structure matters too
27. Natural Reality / F. Chemistry / 2. Modern Elements
17476 Elements survive chemical change, and are tracked to explain direction and properties
17477 Defining elements by atomic number allowed atoms of an element to have different masses
27. Natural Reality / F. Chemistry / 3. Periodic Table
17480 Generally it is nuclear charge (not nuclear mass) which determines behaviour
