No no, I consider this backwards motion. The equation should be t_0 = t_1. The apostrophe is reserved to show the derivative, that is the velocity of time. t' is the rate at which time is increasing = 1 second per second. It should not be equal to the time.

Einstein made a mistake in that section, because he didn't calculate the delay for signals to travel from A to B. If you see a remote 'clock', you don't see that clock in its present state, but in a state some time before. The difference is the delay, which light needs to travel the distance from the remote clock (B) to the observer (at A). Einstein's position was something like this: if you consider some remote clock and see that in a certain state, what you see is real and not what the remote clock does. If you try to synchronize your own clock with the remote one this way, you can do that only on one side, because if the other clock would do the same thing, than unfortunate things would happen and both clocks run backwards after a while. To achieve a symmetric synchronization, you cannot use Einstein's method, but had to measure the delay and introduce it 'by hand' into your calculation (what Einstein didn't). The measurement could be done by a process similar to what is called 'ping' in the internet. But Einstein didn't mention that requirement.

Thomas,
You are describing exactly the problem Einstein starts from.
You write:
"If you see a remote clock, you don't see its present state."
Of course.
Nobody disputes that.
Einstein certainly did not.
His synchronization procedure is specifically designed to compensate for
that propagation delay.
The 1905 construction is not
"look at B and read its current time."
It is
1. A sends a light signal at time tA1.
2. B receives it and immediately reflects it.
3. A receives the reflection at time tA2.
Then A DEFINES the event "reflection at B" to have occurred at
(tA1 + tA2)/2.
This is not forgetting the propagation delay.
It is using the measured round-trip propagation time to define
simultaneity.
In modern terminology, this is exactly a two-way time-transfer protocol.
It is conceptually very similar to what computer scientists know as a
ping.
So your statement
"Einstein didn't calculate the delay"
is simply incorrect.
The delay is the whole point of the construction.
You also write that one must "measure the delay by hand."
But the round-trip measurement
tA2 - tA1
IS precisely that measurement.
Nothing has been forgotten.
Finally, you write that otherwise "both clocks would run backwards."
No.
Nothing in Einstein's synchronization procedure predicts clocks running
backwards.
If you believe it does, then please provide the calculation.
Which equations lead to that conclusion?
Because neither Einstein's paper nor the Lorentz transformations produce
such a result.
Ironically, what you call
"a process similar to ping"
is essentially what Einstein proposed in 1905.
The idea is more than a century old.

"His" synchronization procedure https://en.wikipedia.org/wiki/Einstein_synchronisation was used by telegraphers in the middle 19th century. God only knows wby the idiot bothered before announcing that synchronization is evil and should be abandoned, because it violates some moronic symmetry.

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.

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.

If you send a beam from Earth (A) to -say- Mars (B), the beam will not be reflected in the middle between it was sent out and when it returns. The reason: Mars moves in respect to planet Earth, hence the distance changes, while the ray is still moving. And you cannot 'define this discrepancy away'. > > This is not forgetting the propagation delay. Well, actually Einstein didn't use the word 'delay' anywhere in 'On the electrodynamics of moving bodies'. Also any other equivalent word wasn't used, nor any variable containing delay. Therefore we are requested to respect the intentions of the author and should assume, that he didn't want to consider delay. ... TH

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.
