Dear George Ellis,
May I kindly suggest to you for the third time, please read "On Hertz's Invariant Form of Maxwell's Equations" in Physics Essays, vol.6, number 2, 1993 and also subsequent papers by Thomas E. Phipps, Jr.?
My own knowledge is limited because I was just pointed to the matter by discussions here at fqxi. Nonethelees, I did my best reading and understanding the many belonging textbooks and original papers which were available to me. Unfortunately, I did not manage getting your "Flat and Curved Spacetime".
While your argumentation is understandable, it is incomplete according to Wikipedia:
As early as 1877, while still serving as an officer in the United States Navy, Michelson started planning a refinement of the rotating-mirror method of Léon Foucault for measuring the speed of light, using improved optics and a longer baseline. He conducted some preliminary measurements using largely improvised equipment in 1878. At Helmholtz's laboratory in Berlin Michelson designed and built a fundamental experiment. He had in mind a new sort of interferometer, sensitive enough to measure the second-order effects depending on the velocity of the earth's motion through the ether--that odd, stiff fluid which physicists of the day required as a medium to carry the vibrations of light. Michelson got a null result, and was disappointed. He felt that he had failed to measure the ether. Strictly speaking, the experiments were performed in Potsdam near Berlin because Berlin was too noisy. While the result was published in America in 1881, the European community was certainly earlier aware of it. If I recall correctly Stachel mentioned that Maxwell was skeptical.
The four modern Maxwell's equations can be found individually throughout his 1861 paper, derived theoretically using a molecular vortex model of Michael Faraday's "lines of force" and in conjunction with the experimental result of Weber and Kohlrausch. But it wasn't until 1884 that Oliver Heaviside, concurrently with similar work by Willard Gibbs and Heinrich Hertz, grouped the four together into a distinct set. This group of four equations was known variously as the Hertz-Heaviside equations and the Maxwell-Hertz equations, and are sometimes still known as the Maxwell-Heaviside equations.
Heaviside's notation is still used today. Other important contributions to Maxwell's theory were made by George FitzGerald, Joseph John Thomson, John Henry Poynting, Hendrik Lorentz, and Joseph Larmor.
Both Larmor (1897) and Lorentz (1899, 1904) derived the Lorentz transformation (so named by Henri Poincaré) as one under which Maxwell's equations were invariant.
In the usual formulation Maxwell's equations, their consistency with special relativity is not obvious; it can only be proven by a laborious calculation that involves a seemingly miraculous cancellation of different terms.
It is often useful to rewrite Maxwell's equations in a way that is "manifestly covariant"--i.e. obviously consistent with special relativity, even with just a glance at the equations--using covariant and contravariant four-vectors and tensors.
I assume, you do not like continuing the debate here. More than 400 postings are perhaps already too much.
If you have anything to add, I consider 1364 a more appropriate place because I claim having made Michelson's mistake obvious and hence the block-univere inapt.
Thank you for giving me the opportunity to reveal widespread mistakes.
Sincerely,
Eckard Blumschein
