7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
Supervenience is simply modally robust property co-variance [Hendry]
7. Existence / D. Theories of Reality / 8. Facts / b. Types of fact
That Queen Anne is dead is a 'general fact', not a fact about Queen Anne [Prior,AN]
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa [Hendry]
26. Natural Theory / B. Natural Kinds / 2. Defining Kinds
Maybe two kinds are the same if there is no change of entropy on isothermal mixing [Hendry]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
The nature of an element must survive chemical change, so it is the nucleus, not the electrons [Hendry]
Maybe the nature of water is macroscopic, and not in the microstructure [Hendry]
Maybe water is the smallest part of it that still counts as water (which is H2O molecules) [Hendry]
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / b. Heat
Joule showed that energy converts to heat, and heat to energy [Joule, by Papineau]
Heat is a state of vibration, not a substance [Joule]
27. Natural Reality / D. Time / 2. Passage of Time / e. Tensed (A) series
'Thank goodness that's over' is not like 'thank goodness that happened on Friday' [Prior,AN]
27. Natural Reality / F. Chemistry / 1. Chemistry
Water continuously changes, with new groupings of molecules [Hendry]
Compounds can differ with the same collection of atoms, so structure matters too [Hendry]
27. Natural Reality / F. Chemistry / 2. Modern Elements
Elements survive chemical change, and are tracked to explain direction and properties [Hendry]
Defining elements by atomic number allowed atoms of an element to have different masses [Hendry]
27. Natural Reality / F. Chemistry / 3. Periodic Table
Generally it is nuclear charge (not nuclear mass) which determines behaviour [Hendry]
