27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
12696 Bodies are recreated in motion, and don't exist in intervening instants [Leibniz]
19348 All that is real in motion is the force or power which produces change [Leibniz]
12985 Maybe motion is definable as 'change of place' [Leibniz]
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
12924 Motion alone is relative, but force is real, and establishes its subject [Leibniz]
15307 Leibniz uses 'force' to mean both activity and potential [Leibniz]
12719 Clearly, force is that from which action follows, when unimpeded [Leibniz]
13167 We need the metaphysical notion of force to explain mechanics, and not just extended mass [Leibniz]
13196 All qualities of bodies reduce to forces [Leibniz]
12758 It is plausible to think substances contain the same immanent force seen in our free will [Leibniz]
13192 Power is passive force, which is mass, and active force, which is entelechy or form [Leibniz]
13096 The force behind motion is like a soul, with its own laws of continual change [Leibniz]
13097 Force in substance makes state follow state, and ensures the very existence of substance [Leibniz]
16709 Some people return to scholastic mysterious qualities, disguising them as 'forces' [Leibniz]
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / c. Conservation of energy
20965 Leibniz upheld conservations of momentum and energy [Leibniz, by Papineau]
27. Natural Reality / B. Modern Physics / 1. Relativity / a. Special relativity
12709 Motion is not absolute, but consists in relation [Leibniz]
27. Natural Reality / B. Modern Physics / 4. Standard Model / a. Concept of matter
17411 If all elements are multiples of one (of hydrogen), that suggests once again that matter is unified [Scerri]
17420 The stability of nuclei can be estimated through their binding energy [Scerri]
27. Natural Reality / C. Space / 2. Space
13180 Space is the order of coexisting possibles [Leibniz]
27. Natural Reality / C. Space / 4. Substantival Space
2103 The idea that the universe could be moved forward with no other change is just a fantasy [Leibniz]
27. Natural Reality / C. Space / 5. Relational Space
12952 Space is an order among actual and possible things [Leibniz]
27. Natural Reality / D. Time / 1. Nature of Time / b. Relative time
19384 Space and time are the order of all possibilities, and don't just relate to what is actual [Leibniz]
13181 Time is the order of inconsistent possibilities [Leibniz]
2100 Space and time are purely relative [Leibniz]
27. Natural Reality / D. Time / 1. Nature of Time / e. Eventless time
12955 If there were duration without change, we could never establish its length [Leibniz]
27. Natural Reality / D. Time / 1. Nature of Time / i. Denying time
12720 Time doesn't exist, since its parts don't coexist [Leibniz]
2107 No time exists except instants, and instants are not even a part of time, so time does not exist [Leibniz]
27. Natural Reality / D. Time / 2. Passage of Time / a. Experience of time
2101 If everything in the universe happened a year earlier, there would be no discernible difference [Leibniz]
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
22908 When one element contains the grounds of the other, the first one is prior in time [Leibniz]
27. Natural Reality / F. Chemistry / 1. Chemistry
17392 How can poisonous elements survive in the nutritious compound they compose? [Scerri]
17391 Periodicity and bonding are the two big ideas in chemistry [Scerri]
17404 Chemistry does not work from general principles, but by careful induction from large amounts of data [Scerri]
17415 A big chemistry idea is that covalent bonds are shared electrons, not transfer of electrons [Scerri]
17407 The electron is the main source of chemical properties [Scerri]
17409 Does radioactivity show that only physics can explain chemistry? [Scerri]
27. Natural Reality / F. Chemistry / 2. Modern Elements
17418 It is now thought that all the elements have literally evolved from hydrogen [Scerri]
17398 19th C views said elements survived abstractly in compounds, but also as 'material ingredients' [Scerri]
27. Natural Reality / F. Chemistry / 3. Periodic Table
17406 Moseley, using X-rays, showed that atomic number ordered better than atomic weight [Scerri]
17408 Some suggested basing the new periodic table on isotopes, not elements [Scerri]
17412 Elements are placed in the table by the number of positive charges - the atomic number [Scerri]
17413 Elements in the table are grouped by having the same number of outer-shell electrons [Scerri]
17416 Orthodoxy says the periodic table is explained by quantum mechanics [Scerri]
17414 Pauli explained the electron shells, but not the lengths of the periods in the table [Scerri]
17417 To explain the table, quantum mechanics still needs to explain order of shell filling [Scerri]
17419 Since 99.96% of the universe is hydrogen and helium, the periodic table hardly matters [Scerri]
17395 Elements were ordered by equivalent weight; later by atomic weight; finally by atomic number [Scerri]
17422 The best classification needs the deepest and most general principles of the atoms [Scerri]
17410 Moseley showed the elements progress in units, and thereby clearly identified the gaps [Scerri]
27. Natural Reality / G. Biology / 2. Life
5043 To regard animals as mere machines may be possible, but seems improbable [Leibniz]
27. Natural Reality / G. Biology / 3. Evolution
19414 Men are related to animals, which are related to plants, then to fossils, and then to the apparently inert [Leibniz]
