27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
21202
|
The strong force has a considerably greater range than the weak force
|
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
|
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / a. Electrodynamics
21209
|
Electron emit and reabsorb photons, which create and reabsorb virtual electrons and positrons
|
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields
21212
|
The Higgs field, unlike others, has a nozero value in a state without particles
|
21201
|
A 'field' is just a region to which points can be assigned in space and time
|
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / c. Electrons
21205
|
Many physicists believe particles have further structure, if only we could see it
|
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / d. Quantum mechanics
21203
|
Uncertainty allows very brief violations of energy conservation - even shorter with higher energies
|
21207
|
The Exclusion Principle says no two fermions occupy the same state, with the same numbers
|
27. Natural Reality / B. Modern Physics / 4. Standard Model / b. Standard model
21204
|
The standard model combines theories of strong interaction, and electromagnetic and weak interaction
|
27. Natural Reality / B. Modern Physics / 4. Standard Model / c. Particle properties
21206
|
The properties of a particle are determined by its quantum numbers and its mass
|
21208
|
Eletrons don't literally 'spin', because they are point-like
|
21210
|
Virtual particles surround any charged particle
|
27. Natural Reality / B. Modern Physics / 5. Unified Models / b. String theory
21213
|
String theory only has one free parameter (tension) - unlike the standard model with 19
|
27. Natural Reality / F. Chemistry / 2. Modern Elements
21200
|
An 'element' is what cannot be decomposed by chemistry
