Why do you think that your "standard setting" is relevant to
Einstein's definition of simultaneity?
--------------------------
Why have you not responded to the following?
If it is something you do not understand, ask.
Einstein's _only_ point was to define simultaneity,
it was not to show how you can make two asynchronous clocks
synchronous.
Einstein's method to see if clocks are synchronous,
is a thought experiment.
A thought experiment is to see the logical consequences of a set
of assumptions.
A thought experiment does not prove that the assumptions are true.
quote from § 1. Definition of Simultaneity
-------------------------------------------
| "If at the point A of space there is a clock, an observer
| at A can determine the time values of events in the immediate
| proximity of A by finding the positions of the hands which
| are simultaneous with these events.
| If there is at the point B of space another clock in all
| respects resembling the one at A, it is possible for an observer
| at B to determine the time values of events in the immediate
| neighbourhood of B."
With what kind of precession do you think it in 1905 was possible
to "determine the time values of events" "by finding the positions
of the hands"? And the observer at B had to find the position of
the hands when he saw the ray hit the mirror.
At the very best the precision would be in the order of second,
which is many order of magnitudes more than the transit time.
(Einstein never imagined that point B should be beyond the Moon.)
So of course this is a thought experiment and was never meant
to really be performed. Einstein expected the reader to
understand that. Which physicist and other knowledgeable
people did.
You can't synchronise real clocks with a thought experiment,
so that was obviously not Einstein's intension.
I have posted the following before. Will you read it this time?
---------------------------------
This document defines The Special Theory of Relativity(SR):
https://paulba.no/paper/Electrodynamics.pdf
SR is a mathematical consistent theory.
(If it weren't, it would have been born dead.)
That means that SR is what Einstein says it is,
you can't claim that Einstein is wrong.
Your or anybody's opinions are irrelevant.
It is even irrelevant if SR's predictions are
in accordance with measurements.
(But if they weren't SR would long since been
forgotten and we wouldn't have this discussion.)
We start with this quote:
quote from § 1. Definition of Simultaneity
-------------------------------------------
| we establish
| by definition that the “time” required by light to travel
| from A to B equals the “time” it requires to travel from
| B to A."
Note that this statement imply that A and B are stationary
relative to each other.
This definition together with the two postulates of SR means:
The speed of light is isotropic c by definition.
This is a definition of simultaneity, se below.
That two clocks are synchronous means that they
simultaneously show the same.
Now Einstein made the following _thought experiment_:
quote from § 1. Definition of Simultaneity
-------------------------------------------
| "Let a ray of light start at the “A time” tA from A towards B,
| let it at the “B time” tB be reflected at B in the direction
| of A, and arrive again at A at the “A time” t′A."
tA is the time shown by the clock at A when the ray leave A.
tB is the time shown by the clock at B when the ray hits B.
t'A is the time shown by the clock at A when the reflected
ray hits A.
In a thought experiment measurements can be made with
infinite precision, and we can sit at our desks and analyse it.
The transit time is d/c where d is the distance between A and B.
Let clock B be F ahead of clock A, where F is between 0 and
a long time.
We then have: tB = tA + d/c + F
and: t'A = tB + d/c - F
so: (tB - tA) = d/c + F
(t'A - tB) = d/c - F
If (tB - tA) = (t'A - tB) then (d/c + F) = (d/c - F),
which is true only if F = 0,
the clocks simultaneously show the same.
This means:
TB = (TA + d/c)
When clock B shows TB clock A simultaneously
shows (TA + d/c), which is the same.
t'A = (tB + d/c)
When clock A shows t'A clock B simultaneously
shows (tB + d/c), which is the same.
Thus:
In accordance with definition the two clocks are synchronous if
tB − tA = t′A − tB.
This is a logical consequence of the postulates of SR
and that the speed of light is isotropic.
Einstein's definition of simultaneity is mathematically
consistent.
This doesn't say anything about whether or not SR's
predictions are in accordance with measurements.
Only real experiments can do that.
