so true indeed; Kasparov’s real name is Garik Weinstein.

Those not Jewish at all would be Karpov, Spassky, Petrosian, Keres.

And this is why Einstein's synchronisation method is:
"total nonsense and full of errrors from start to finish" ?

No, the reasons are different.

exactly, indeed, the americans are working for us. I like america. They 
just shit on about $500 milliards for a fictitious natzi territory named 
ukrane, for the capitalist collective_europe, what can you do.

i dont think the Russians will forget what your deepen corrupt terrorist 
regime did with their energy pipelines at the bottom of the sea.

This was a quote from me, but not about the method to synchronize clocks.

I meant the entire text with 'full of errors'.

The number of errors is extremely large and counts in the hundreds.


And I didn't believe for a minute, that Max Planck was unable to see at 
least a few of them, hence the entire thing was fraudulent on the side 
of the publisher, too.

My guess about this was, that the text was meant as 'mocking' of the 
general public.

The scientific audience must therefore been silenced by other means.

It didn't work completely, because about three thousand critical 
articles and books were printed, which dealt with that particular text.

But Einstein's method to synchronize clocks was actually also wrong.

This caan be seen, if you compare Einstein's text ('On the 
electrodynamics of moving bodies') and what Einstein wrote there about 
this method in comparison to how that should actually be done.

I wrote about how the method should be (but wasn't), that you need to 
measure the delay for the 'round trip', devide that by two and use the 
result as correction of the own time value.

E.g. you want to adjust a clock on the Moon, which is one light-second away.

Then you first need to send a signal there, which gets reflected on the 
Moon and sent back to Earth.

The round trip shall last, say, two seconds, then the delay would be one 
second.

This one second you would add to, say, 1:00:00 pm, which is the currect 
time here.

Therefore you need to encode 01:00:01 pm into the signal, which you need 
to send to the Moon.

There the Man-on-the-Moon reads the signal and dials the Moon-time-clock 
to 01:00:01 pm. Now both clocks are synchronized (supposed the tick rate 
is also equal).

But Einstein used an entirely different method and didn't even mention 
delay.

not true. You don't have to encode. The second is defined by a shit in a 
state, inherently at a speed of infinity. There is no rise or fall time. 
Try think. A shift is a infinitely high peek with size zero in frequency.

How could you know that this is the "currect" time herer or there if the 
clocks are not synchronized? You have a chicken-and-egg problem here.

No, you needn't. There is a simplier way, which the one Einstein describe.

When you substract values from two separated clock you cannot know in 
advance if the result is a delay or not. It relies on synchronisation.

When you substract values from ONE single clock THEN you know that is a 
delay, so when Einstein wrote 2AB/(t'A - tA) every decent reader would 
recognize t'A - tA as a "delay".

Then when he define synchronisation as the property that tB - tA = t'A - 
tB, again everyone with a very minimal clue would recognize that IF THE 
PROPERTY IS TRUE tB - tA and t'A - tB are delays.

If tB - tA =/= t'A - tB then it is easy to compute the offset that should 
be applied to any of the clocks, even to both if you wish. See : 
https://noedge.net/e/ this is DIRECT application of formulas from 
Einstein's article : 1) first to check if clocks are in sync and 2) to 
compute the offset to be applied in order to make them so (Einstein did 
not address this directly in his paper as it is trivial to deduce from the 
*checking* synchronisation procedure)

Nobody on Earth was, back then, stupid enough to interpret this as taking 
the reading of the remote clock as the value to be set. This is utterly 
asinine.

Let's review what "Einstein's method to synchronize clocks" is.
The very first paragraph of Einstein's paper is:

   § 1. Definition of Simultaneity
The definition is:
  "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.
   . . .
   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.
    In accordance with definition the two clocks synchronize if
       tB −tA = t′A −tB.
   "
This equation can be written: tB = tA + (t'A-tA)/2
The transit time for the ray to go from A to B or from B to A is
"delay" = (t'A-tA)/2

In words:
If the clock at A shows t when a ray of light is sent,
then the clock at B is synchronous with the clock at A if it
shows t plus the transit time (delay) when the pulse is received.

Note. Einstein only give the definition of simultaneity,
he say what the clocks should read to be synchronous.

He does not say anything about how to sync non-synchronous clocks.
This depends on the available instruments etc., and doesn't belong
in a _definition_ of simultaneity.

A _definition_ can't be wrong.

Right.
According to Einstein the clocks are synced if tB = tA + (t'A-tA)/2

'delay' = (t'A-tA)/2

> > E.g. you want to adjust a clock on the Moon, which is one light-second
> away.

I note with interest that you now have realised that you must have
an observer on the Moon, and you are using Einstein's definition
of simultaneity, the definition you claimed was wrong.

The 'delay' is measured in Einstein's method.

So you are trying to set the clock at the Moon to show
   tB = tA + (t'A-tA)/2

In accordance with Einstein's definition!

However, your method of synchronising non-synchronous clocks can
hardly work. If we are synchronising atomic clocks the synchronisation
should probably be within a ns or better.
tA is the time at the start of the signal and so is tB.
Your coded signal will have to be several ns long.
Go figure!

----------------

I have told you several times how it can be done:
This is one possible way:

Clock at B will probably not be synchronous with clock at A.
So let B's reading of the clock when the ray is reflected be tx.
The observer at A has measured tA and t'A.

The observers have now to communicate.
When B is at the Moon, observer A would probably use
a radio transmitter, and B would have a receiver.

Observer at A can then send tA and t'A to observer at B.

The Moon observer knows that according to Einstein:
  "The two clocks synchronise if  tB − tA = t'A − tB."

So he knows that to be in sync, clock at B should have shown
tB = tA + (t'A-tA)/2 = (tA + t'A)/2

But since it showed tx, he must add the correction:
δ = tB - tx = (tA + t'A)/2 - tx

So when he corrects the clock at B with δ,
it will be in synch with clock at A.

Note that if at a later time the clock at B shows t,
then the correct time is t+δ.

That is:  δ shouldn't be added to tx, but to current time.

  >
> But Einstein used an entirely different method and didn't even mention 
> delay.

You are really something. :-D

I have told you at umpteen times:

Einstein:
"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."

That is: the clocks are synchronous if the 'delay' forth is
the same as the 'delay' back.

Is your problem that you don't find the transit time of the ray
called by the word "delay" ?

Why am I expecting you to keep saying
"Einstein didn't even mention delay? :-D

Sure, that's correct!

I have actually written that several times already, but you have always 
rejected my demand.

But the question wasn't, what I think or you, but what Einstein wrote in 
his paper.

And there ain't no such thing as 'delay'.

Einstein simply ignored the 'technical' requirements for synchronization.


> Note. Einstein only give the definition of simultaneity,
> he say what the clocks should read to be synchronous.


But Einstein's definition was nonsense!

It is obvious, that the transit of a signal needs a little bit of time 
and that this time follows after the event, if a signal from an event is 
interpreted somewhere.

For a proper definition of simultaneity you need to consider the delay 
and subtract it afterwards again from the remote measurement.

Or in the other direction:

if you watch a remote clock and read out the remote time, you need to 
add the delay to that reading, if you want to know the present time at 
the remote station.

Sure.

But we're talking about principles and whether or not those make sense.

And Einstein's principles didn't make sense.

Well, in a way that is true, but would justify nonsense.

All of this wasn't written in Eisntein's paper.

It would have been easy to rearrange the equations and derive, what you 
had witten.

But Einstein didn't do that.

No such thing as 'delay' occured in Einstein's paper.

'Lichlaufzeit' was mentioned, which is almost the correct thing, but 
that time wasn't used to compensate the delay.

Therefore my guess was: Einstein didn't wanted to correct the error 
caused by the delay.

This is IMHO possible, because an observer at A could see B.

It is in fact nonsense to assume an observer on the Moon, but we could 
use the laser reflectors there or assume a future Moon station.

Now we could see, that t_B is irrelevant in Einstein's setting, hence 
also, whether or not there is an observer on the Moon.

Sation A measures simply the delay for the entire 'round trip', which is
t'_A - t_A =delay_roundtrip

The half of this value is the delay for one direction and that could be 
used to adjust the encoded time, which sent to the Moon-station.

But in the end both clocks don't get synchronized mutually, because 
simply clock B is adjusted to clock A.

Of course it is.

Your 'demand' which I have 'rejected' was that Einstein's
definition above was wrong because he had ignored the 'delay'.

This is too stupid!

Your 'delay' is obviously the transit time for the light
to go from A to B, or from B to A.

Einstein's definition of simultaneity in Einstein's words:
"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."

Einstein's definition of simultaneity with math:
"In accordance with definition the two clocks synchronize if
        tB −tA = t′A − tB."

Expressed in words:
"In accordance with definition the two clocks synchronize if
  the transit time from A to B is equal to the transit time
  from B to A."

The equation above can be written: tB = tA + (t'A-tA)/2

So Einstein's definition can be written:
"In accordance with definition the two clocks synchronize if
     tB = tA + (t'A-tA)/2"

Expressed in words:
"In accordance with definition the two clocks synchronize if
  the clock at A shows t when a ray of light is sent, and
  the clock at B shows t plus the transit time  when the ray
  is received."

There is no way to express Einstein's definition without
including the transit time. It is all about the transit time!

So how did you manage to read Einstein's paper and miss
that the transit time is mentioned over and over?

---------------------

You have now admitted that Einstein's definition is correct.

So stop claiming that the transit time is ignored.

Case closed!

In Aleut language (https://en.wikipedia.org/wiki/Aleut_language) the word

written in latin alphabet as "shark".

And I guess what is pronounced as "synchronization"
in the mad newspeak of your mad ideology may fit
the mad definition of your mad guru. Not in English,
however.

LOL.

It is quite incredible that physicists were able to understand the notion 
of relativity of chronotropy by a change of reference frame, but without 
understanding that of anisochrony by a simple change of position."

I agree to the idea of local time, but would not reject a 'plane of 
simultaneity'.


In relativity lingo a 'plane of simultaneity' is called 'spacelike'.

That is technically a hyperplane (commonly called 'present').

It could be defined by a hypothetical signal with infinite velocity.

This hyperplane is comoving with the observer and connects a realm, 
which actually invisible, though real.

I'm not sure you understand what I'm saying.
It gives a rather unpleasant impression.
A bit like if for forty years, a man had been saying that he was injured 
falling from a horse, and by the word "horse," everyone understood that he 
had fallen from a rabbit.
All of this is quite incredible. It's still not normal, even if sometimes 
the language barrier can play tricks, that no one, ever, understands this 
idea of the relativity of the hyperplane of present time between two 
distant observers, making perfect synchronization and absolute 
simultaneity of their respective existences impossible.
No one seems to understand that Juliet, sitting on this bench, and Romeo 
sitting on that other one, although in the same courtyard, but separated 
by a distance of 30 meters, will never live in the same absolute present 
time. This is what is called universal anisochrony. Their universal 
present time plane is relative, and entirely personal. Two simultaneous 
events for Romeo (she beeps at the same time as him for him) will no 
longer be simultaneous for Juliet (for her, in this case, Romeo beeped 
much later delta_t=2x/c).
