Talk:History of special relativity#Local time

As part of the history, I'm interested in the now-standard term "special relativity." When did this theory become known as the "special" version of relativity; once the theory of "general relativity" had come out? And, when did the term "relativity" become associated with both theories? -- Dan Griscom (talk) 00:27, 1 May 2023 (UTC)

"This can be stated as: as far as the laws of mechanics are concerned, all observers in inertial motion are equally privileged, and no preferred state of motion can be attributed to any particular inertial observer."

This sentence is Einsteinian jargon, Newton would never have said something like this. Newton would not have used the word "observers" in this context. I think that this sentence needs to be restated without the relativistic jargon. Zeyn1 (talk) 12:07, 5 October 2024 (UTC)

: I think that in this context we can confidently interpret an observer as a person who is making observations, which Newton certainly could have easily conceived. Furthermore, this phrasing has the advantage of paving the way for the more strict jargon that is used in special relativity, which after all is the subject of the article.

:Also, note that this phrasing is directly taken from Poincaré. See &4 in section History of special relativity#Lorentz's 1904 model.

: So, i.m.o. there is no problem — on the contrary actually. - DVdm (talk) 12:45, 5 October 2024 (UTC)

Does Henri Poincaré was contributed with empirical findings?

My understanding his contribution was creating a mathematical theory for Einstein’s theory based on early findings. Amid.ukr2 (talk) 03:39, 31 December 2024 (UTC)

@William M. Connolley [https://en.wikipedia.org/w/index.php?title=History_of_special_relativity&curid=1790788&diff=1287065654&oldid=1287051969 changed] a sentence:

• Maxwell's thought all optical and electrical phenomena propagate through an aether, making his equations valid only for systems at rest with respect to that aether.

to

• This theory was interpreted as saying that optical and electrical phenomena propagate through an aether, making the equations valid only for systems at rest with respect to that aether.

But the source says:

• Maxwell himself thought that electromagnetic waves were carried by a medium, the luminiferous ether, so that his equations would hold only in a limited class of Galilean inertial frames, that is, those coordinate frames at rest with respect to the ether.

I will restore the previous version (but fix the spelling mistake).

I don't know but I guess the change was made to emphasize that the aether theory was widely supported? I made some additional adjustments to this end. Johnjbarton (talk) 23:10, 23 April 2025 (UTC)
