Introductory Discussion of Waves and Light in Space and Time

- Ways to understand relativity: Rigid frames vs. lightwaves. Comparing colored waves (CW) vs. pulse waves (PW) or particle frames
- Visualizing Waves: Using Earth as a clock
*,*Tesla's AC Phasors , Phasors using complex numbers. - Keeping the Phase: How fast is light? How do we quantify or "clock" wavespeed? What is Col or? Spacetime vs. per-spacetime
- Beats, Groups and Phase: Interfering waves make spacetime tracks.

Overview of wave drawn squares & diamonds in spacetime

Light meets light: CW pairs and half sum & difference rule, CW and PW examples

PW Propagation as Composition of CWs, Bidirectional PW Propagation

Discussion of Axioms about Light in Space and Time

- Pulse Wave (PW) Axiom

*“Lightning flash appears to go the same speed regardless of what train you’re on.“* - Continuous (or "Colored") Wave (CW) Axiom
*(CW is Occam "razorcut" of PW)*Evenson :

*“Laser light goes the same speed regardless of what color it is.“*

- Time Reversal Axiom:

Discussion of Main Results

- Doppler and CW light
__derives spacetime and per-spacetime relativity all at once.__ - How Euclid's 3 means quantify relativistic coordinates and Hyperbolic geometry.
- How 2-CW-light derives relativistic and Newtonian classical mechanics.
- Quantized frequency, wavenumber and field amplitude. What's the matter with light? Three kinds of mass.
- Coherent-states vs. photon-number-states, Light, Energy and Flux: 2-CW vs. 1-CW light, Psi-Amplitudes and Probability Psi*Psi
- Compton scattering, Einstein elevators, Poincare invariants relate Hamiltonians and Lagrangians
