WAVES AND QUANTUM PHYSICS:
- Why Waves? Explain by a one-page physics summary from 1600-1900…
Galileo notes physics in a steadily moving boat, a spacetime transform to a moving reference frame, –» V x´ = x + Vt
Newton gives law of motion of mass m under force F F = m d²x/dt²
Time has entered, quantitatively, but not in the force laws: Fgrav = -GmM/r², Felectric = qe/(4??r²) of Newton and Coulomb.
Time really enters when Faraday discovers electricity induced by time-varying magnetism and Maxwell codifies it, generated two crises relating to electromag Waves.
