27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
Relativity and Quantum theory give very different accounts of forces
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / a. Energy
Thermodynamics introduced work and entropy, to understand steam engine efficiency
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / a. Electrodynamics
Spinning electric charge produces magnetism, so all fermions are magnets
Photons are B and W bosons, linked by the Higgs mechanism
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / c. Electrons
Electrons are fundamental and are not made of anything; they are properties without size
Electrons may have smaller components, bound by a new force
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / d. Quantum mechanics
Quantum mechanics is our only theory, and is very precise, and repeatedly confirmed
Physics was rewritten to explain stable electron orbits
Virtual particles can't be measured, and can ignore the laws of physics
27. Natural Reality / B. Modern Physics / 3. Chromodynamics / a. Chromodynamics
Colour charge is positive or negative, and also has red, green or blue direction
27. Natural Reality / B. Modern Physics / 4. Standard Model / b. Standard model
The Standard Model omits gravity, because there are no particles involved
In Supersymmetry the Standard Model simplifies at high energies
Standard Model forces are one- two- and three-dimensional
27. Natural Reality / B. Modern Physics / 4. Standard Model / c. Particle properties
Quarks and leptons have a weak charge, for the weak force
27. Natural Reality / B. Modern Physics / 4. Standard Model / e. Protons
Quarks rush wildly around in protons, restrained by the gluons
27. Natural Reality / B. Modern Physics / 4. Standard Model / f. Neutrinos
Neutrinos only interact with the weak force, but decays produce them in huge numbers
27. Natural Reality / B. Modern Physics / 5. Unified Models / c. Supersymmetry
To combine the forces, they must all be the same strength at some point
27. Natural Reality / C. Space-Time / 1. Space / e. Relational space
'Space' in physics just means location
27. Natural Reality / D. Cosmology / 8. Dark Matter
The universe is 68% dark energy, 27% dark matter, 5% regular matter
27. Natural Reality / D. Cosmology / 9. Fine-Tuned Universe
If a cosmic theory relies a great deal on fine-tuning basic values, it is probably wrong
