In physics "synchronous" means that two clocks simultaneously

When two clocks are side by side and show the same,

At home you set your clock to  UTC+1h.
You know the station clock shows UTC+1h.
You expect the clocks will be synchronous within a second
when you arrive at the station.

Or wouldn't it? :-D

If the watches are well tuned, it is logical that when I find myself

The opposite would also be absurd, since by definition they must be
tuned.

OK. So we can sum it up:

You know the station clock is "tuned" to show UTC+1h.
Since your clock and the station clock are well "tuned",
you expect the clocks will show the same when you arrive
at the station.

If the reader thinks that "being tuned" is the same as
"being synchronous", he is wrong, as Richard will explain below:

I remind you and those who read: "Paul B. Andersen is not an idiot, he
understood very well what the concept of chronotropy is, which is the
study of the relativity of the internal beats of watches. He knows
that by permutation of reference, it is the opposite watch that beats
less quickly and that t'(its time for me) = tau (its time, for it) /
sqrt (1- Vo² / c²).

But to this is added ANOTHER concept, the concept of anisochrony, that
no one (not Paul any more than the others WANTS to understand).

The rest is just discriminatory will: "We do not want Dr. Hachel to

Note that when you say: "I tune my watch to the universal watch" you
are making a conceptual error. You do not tune your watch to it, but
it is it that tunes to you.

All the synchronizations of the universe that are done on it, it is

everything that is agreed on it at this moment constitutes HER present

This is the primum movens of the theory of relativity, and if we do

but whose basis is lame.

If you do not understand why the synchronization of physicists
(universal time) is an infinitely useful creation, but abstract,
virtual, and representing nothing in itself (this watch is nowhere in
our 3D universe), you still have not understood the theory of relativity.

Actual clocks always observe remote clocks
in a "range" of time.
It's kind of like sonons, photons,
about instantons being solitons,
they're extended bodies.
("Measurements of time.")
Clocks either slow, or meet.  Clocks
are mostly according to Doppler.
Particles as point particles and
instants as distinct, are not classical
quantities, though they are mathematical.
