Just gobbledygook.

 Voilà un mot bien hardi envers le docteur Hachel, et surtout bien injuste.

 If you don't like that word then learn to use the Common Language.

 Dr. Richard Hachel is probably one of the Usenet posters most attached to the meaning of language and most saddened by the fog of words.

The important thing to learn is not the meanings of the words but the
words of the meanings.
The fog of words can be largely avoided by the use of equations. Words
are only needed when the equations need be connected to the real world.
For that purpose one should use well known words as much as possible and
definitions whenever the usual dictionary meaning is too obscure or
vague.

Especially the fog of concepts in SR, where it is very difficult for the novice, or even the big shot, to understand what he himself is saying (the relativistic Joe Biden phenomenon).

The concepts of SR are not foggy. If some presentation is then try some
other one or ask here.

I have never introduced words, principles, or concepts without a precise idea of ​​what I was saying.

An idea is not sufficient. The best option is to avoid introduction of
new words and the second best to present good definitions. New principles
are not principles of SR so not applicable in this context. New concepts
must be related to the original ones. If that cannot be done they are
not relevant in this context.

And if you look closely, I have only introduced two new words (anisochrony and chronotropy) and four new concepts (elasticity of distances which is responsible for a spatial zoom effect definitively explaining the Langevin paradox, more accurate calculation of the proper times of accelerated objects, radial contraction of the relativistic disk,
vision of the universe live for any observer).

And they have served no useful purpose.
