Maciej,
Thank you.
This is actually another interesting concession.
You now write that Einstein's synchronization procedure was already used
by telegraphers.
Exactly.
Nobody ever claimed that exchanging timing signals was Einstein's
invention.
In fact, by the end of the nineteenth century, synchronization of
distant clocks had become a major practical engineering problem for
railways, telegraph networks and geodesy.
Henri Poincare was directly involved in these questions.
As president of the Bureau des Longitudes, he supervised work on the
synchronization of clocks between distant observatories and railway
stations using telegraphic signals.
So yes, practical synchronization procedures certainly existed before
Einstein.
But that completely misses Einstein's contribution.
Einstein did not invent the exchange of signals.
He turned an engineering procedure into an operational definition of
coordinate time.
That is a completely different achievement.
Before Einstein, engineers synchronized clocks because they assumed there
already existed an absolute time that the clocks should reproduce.
After Einstein, the synchronized clocks DEFINE the coordinate time of an
inertial reference frame.
The synchronization procedure is no longer merely a practical trick.
It becomes part of the definition of spacetime coordinates.
That conceptual step is precisely what made the 1905 paper revolutionary.
Ironically, your historical remark therefore supports Einstein rather
than refutes him.
And it also contradicts what you have been claiming for several days.
You first argued that Einstein's synchronization procedure was absurd,
unusable and abandoned.
Now you tell us that essentially the same procedure had already been used
successfully by engineers before Einstein.
Those two claims cannot both be true.
Finally, there is another irony.
As an "information engineer", you should immediately recognize the
difference between
implementing a protocol
and
defining the semantics of the protocol.
Telegraph engineers implemented a synchronization protocol.
Einstein explained what the protocol means physically and made it the
foundation of coordinate time.
Those are not the same contribution.
Since, by your own admission, you like speaking of "opening one's
muzzle", perhaps you were not in the best position to open yours yet
again.

That said, it's quite easier sometimes to live in a world of theory than practice, yet, from the theory side then for suitable practices, and from the practice side suitable theories, here it's deemed reasonable to at least have a perfect theory, then for the practice of theoretical practice and practical theory, the application of applications.

Einstein doesn't care what actually "makes the tensors", in General Relativity, then usual acconts extrapolated from space-contraction in Special Relativity plainly say "the metric and norm aren't the same, and for matters of perspective, from one perspective, this might be what we'd see". Of course there's that "Relativity of Simultaneity is non-local", Einstein says so in "Out of My Later Years", while many SR-ians don't know / don't care the difference.

Thomas,
You have changed the thought experiment.
Einstein's synchronization procedure is defined for two clocks at rest in
the same inertial frame.
You replaced that by
Earth
Mars
which are not at rest relative to each other.
Of course the simple synchronization construction no longer applies.
Nobody ever claimed that it should.
You are criticizing Einstein's procedure after removing one of its
fundamental hypotheses.
That is not a valid objection.
In Einstein's original notation, the procedure is the following.
Clock A sends a light signal when it reads
t_A.
Clock B receives the signal and immediately reflects it when it reads
t_B.
Clock A receives the reflected signal when it reads
t'_A.
Einstein then defines the clocks to be synchronized if
t_B - t_A = t'_A - t_B,
or equivalently,
t_B = (t_A + t'_A)/2.
Nothing has been forgotten here.
The entire construction is based on the finite propagation time of the
light signal.
If light propagation were instantaneous, there would be no need to
introduce the three times
t_A,
t_B,
t'_A
in the first place.
Your Mars example is a different problem.
Mars is moving with respect to Earth, so the distance between the
endpoints
changes while the signal is in flight.
Einstein's synchronization procedure is not intended for that situation.
Modern spacecraft tracking and radar ranging explicitly model the motion
of
the endpoints.
That is an extension of the problem, not a correction of Einstein's
procedure.
Finally, your linguistic argument is extraordinary.
You write that Einstein never used the word "delay", therefore he did not
take propagation time into account.
Scientific papers are interpreted from their mathematics, not by counting
the occurrences of particular words.
The quantities
t_A,
t_B,
t'_A
exist precisely because light takes time to propagate.
The propagation delay is not missing from the paper.
It is the entire reason the synchronization procedure exists.

No, that's wrong, because the very word 'relativity' indicates relative
motion.
Now we have much higher velocities in space than that of trains.
We could easily have relative velocities of half c between objects in
outer space.
Then 'relativity' needs to deal with that situation, too, because
otherwise it wouldn't do anything at all.
What Einstein in fact did, that was actually bunk, too:
he introduced velocity 'solo', (meaning: without referring to anything
but space itself.)
What Einstein should have done, but didn't, was to deal with the change
of observations with the change of relative positions.
Instead he introduced a hidden reference ('the universe'), even if he
declared, that 'absolute space' would not exist.

Thomas,
You have again replaced Einstein's problem by another one.
Einstein's 1905 synchronization procedure begins with two clocks, A and B,
at rest relative to one another
in a single inertial reference frame.
That is the situation to which the definition applies.
You now replace B by Mars.
Mars is not at rest relative to the Earth.
It is therefore no longer the problem Einstein is discussing.
Of course, if B moves while the light is in flight, the midpoint of the
round-trip is no longer the reflection event.
Nobody disputes that.
It is simply a different physical situation.
You also write:
"the very word 'relativity' indicates relative motion."
No.
The principle of relativity states that the laws of physics have the same
form in all inertial frames.
It does not say that every calculation must involve bodies moving relative
to one another.
In fact, the first step in special relativity is precisely to define the
coordinates of a single inertial frame.
Only afterwards are different inertial frames compared.
You also claim that Einstein introduced velocity "without referring to
anything but space itself."
Again, no.
Velocity is always defined with respect to a specified reference frame.
There is no such thing in special relativity as a velocity "with respect
to
space itself."
Finally, your remark
"Einstein should have dealt with the change of observations with the
change of relative positions"
describes exactly what the Lorentz transformation does.
It tells you how the coordinates assigned to the same event change when
you
move from one inertial frame to another.
That is literally its purpose.
So your criticism is not that Einstein forgot to consider relative motion.
It is that you have substituted a different thought experiment (Earth and
moving Mars) for the one he actually analyzed (two clocks at rest in one
inertial frame), and then concluded that his definition does not solve the
problem you introduced.
No definition can be expected to solve a different problem from the one it
was intended to address.

Sure, the definition proposed by the idiot

Yet modern timing systems inspired by exactly the same synchronization
principle routinely achieve nanosecond accuracy.
The OPERA experiment between CERN and Gran Sasso is one example.
The timing chain explicitly calibrates
- GPS propagation,
- optical fibres,
- electronic delays,
- cable delays,
- portable Cs clock comparisons,

You may easily say anything is "inspired"
by the mumble of the idiot, there is no way
to prove the opposite.

The truth is, of course - the idiot was trying to ban
any synchronization because in his moronic delusions
ideal clocks are local clocks.

Maciej,
No.
Quite the opposite.
The reason engineers use expressions such as
"would appear to an observer"
is precisely because engineering specifications distinguish between
- the local quantity produced by the hardware,
and
- the quantity observed in a specified reference frame.
That is normal engineering language.
As for your claim that there is "no way to prove" that modern timing
systems are inspired by Einstein synchronization, there actually is.
The literature is full of it.
For example, synchronization procedures used in particle accelerators,
space navigation and satellite navigation are explicitly based on the
same operational convention:
synchronize distant clocks by exchanging light signals and assigning
the remote event the time
(t_A + t'_A)/2
within a chosen inertial frame.
That is exactly Einstein's 1905 construction.
The implementation is, of course, much more sophisticated today:
atomic clocks, optical fibres, calibrated delays, relativistic
corrections, common-view GNSS, etc.
But the operational principle is the same.
So this is not a matter of saying that everything is "inspired by
Einstein".
The engineers themselves say so.
Ironically, you have spent days claiming that Einstein's synchronization
procedure was never used in practice.
Yet the first person in this discussion to support his claims with
actual engineering specifications was Paul Andersen.
You have replied with insults.
You have not produced a single engineering document stating that GPS
uses your alternative definition of clocks.
Nor have you produced any specification replacing Einstein's
synchronization convention by another operational procedure.
In science and engineering, documents carry more weight than invective.

You have spent several days arguing against a procedure whose existence
is demonstrated by the very section of Einstein's paper entitled
Definition
of Simultaneity. It is difficult to claim that Einstein "banned
synchronization"
when he begins by defining it.

No.
The reason why a SINGLE engineer has used
expressions such as
"would appear to an observer"
is that he felt urge to write that something
matches The Shit he believed, and apart
of "what would appear" - nothing matches.

It is remarkable that, whenever an technical document contradicts your
claims, your conclusion is never that your claims might be wrong. Instead,
the document is declared to have been written by an Einstein worshipper.
That is not an engineering argument; it is an unfalsifiable one.

It's remarkable that a fanatic relativistic
piece of shit is lying and slandering
whenever it can, as it is too stupid
for anything else.

Since "would appear to an observer" is also
unfalsifiable one - expecting engineering arguments
against that is utterly idiotic (but not unexpected).

Maciej,
No.
The statement
"would appear to an observer in the Earth-centered frame"
is not unfalsifiable.
It is one of the most falsifiable kinds of statement an engineer can make.
It predicts a numerical measurement.
The GPS specification states that if the onboard oscillator is preset to
10.2299999954326 MHz
then it will be measured in the Earth-centered reference frame as
10.2300000000 MHz.
That prediction can be tested.
Either the measured frequency is
10.2300000000 MHz
within the specified tolerances,
or it is not.
There is nothing "unfalsifiable" about it.
By contrast, your explanation is
"the engineer secretly believed Einstein."
That is the unfalsifiable statement.
No experimental measurement can determine the engineer's private beliefs.
One explanation concerns a measurable frequency.
The other concerns the supposed psychology of the document's author.
Only one of these belongs in an engineering discussion.
