green numbers give full details    |    back to list of philosophers    |     expand these ideas
5. Theory of Logic / L. Paradox / 4. Paradoxes in Logic / a. Achilles paradox
Zeno assumes collecting an infinity of things makes an infinite thing
7. Existence / B. Change in Existence / 2. Processes
Quantum mechanics deals with processes, rather than with things
7. Existence / B. Change in Existence / 4. Events / b. Events as primitive
Quantum mechanics describes the world entirely as events
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
There are probably no infinities, and 'infinite' names what we do not yet know
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / d. The unlimited
The basic ideas of fields and particles are merged in quantum mechanics
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields
Because it is quantised, a field behaves like a set of packets of energy
There are about fifteen particles fields, plus a few force fields
The world consists of quantum fields, with elementary events happening in spacetime
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / c. Electrons
Electrons only exist when they interact, and their being is their combination of quantum leaps
Electrons are not waves, because their collisions are at a point, and not spread out
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / d. Quantum mechanics
Quantum Theory describes events and possible interactions - not how things are
27. Natural Reality / B. Modern Physics / 4. Standard Model / a. Concept of matter
Nature has three aspects: granularity, indeterminacy, and relations
27. Natural Reality / C. Space-Time / 1. Space / d. Substantival space
The world is just particles plus fields; space is the gravitational field
27. Natural Reality / C. Space-Time / 2. Time / i. Time and change
Only heat distinguishes past from future
