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
• : How do Doppler and work?

Discussion of Axioms about Light in Space and Time

• Pulse Wave (PW) Axiom
       Einstein : “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: becomes
  

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
