I guess, there is no way to rescue SR without sticking on this > "synchronization". You don't get it. Me too, can't understand what on earth is wrong with you, electrical engineers. SR is NOT about clocks and any synchronization. There is no demand of synchronization anywhere, in my Divergent Matter of the Moving Bodies Model. Hmmm, these former electrical engineers sincerely believe they need clocks in order for SR to happen.

Not really. Speed is ALWAYS referred to some coordinate system. You are free to
construct coordinates in which the medium, the "stationary object", or the
"moving object" is at rest.
One could choose inertial coordinates in which some object is
at rest, or one could choose rotating coordinates in which the
object is at rest (at the center of rotation). The speeds of
other objects relative to these two coordinate systems will be
quite different. But both could be described as "speed relative
to that object", making this phrase ambiguous or useless.

There is no principal difference between natural reference for speed for cars and sound waves. Cars have natural reference in Earth. Sound has natural reference in medium. It does not generally mean ( in context of physics ) speed of a car/sound = speed of car/sound wrt Earth/medium. Car speed wrt Earth is convenient and natural, but arbitrary. Sound speed wrt medium is convenient and natural, but arbitrary.

You have to admit that you and Roberts are wrong when we consider a stone that is thrown from one train to another one moving relative to each other. In this case one must arbitrarily decide whether the emitting or the hit train are the reference. Does the speed of a bullet refer to a moving re ground cannon or to a differntly moving target? The decision is arbitrary, not natural. However, the speed of sound doesn't depend on any chosen point of view.

Einstein used the often confusingly defined notion "inertial coordinate system" as he clearly wrote on p. 892: "... starren Körpern (Koordinatensystemen)" [rigid bodies (coordinate systems)]. In this sense, the emitter is a chooseable coordinate system, and the receiver is also a chooseable coordinate system. Aaron Bernstein's rider on a photon is hardly a coordinate system, although Einstein was inspired by this fiction writer.

And where is our supposed error ? We can choose as the reference the coordinate system of a stone in rest. ( even if it would not be a good idea.) Any choice of a coordinate system is arbitrary.

Natural in the sense of being close to human mind is arbitrarily choosing the natural one, not being given it in advance. BTW, it is not the only possible natural choice.

Your disagreement is merely YOUR problem, and does not change the FACT that what
I said is correct. This _IS_ what these words mean (in this context, i.e.
physics; in casual speech the meaning is not so precise).
That's why your attempt to define "speed" without using coordinates
is so ludicrous -- the word ALREADY has an explicit meaning. But
you do not know enough about the subject to recognize your own
incompetence and ignorance. I have already discussed this....

NONSENSE! You are VERY confused and have missed a basic point of SR.

NONSENSE! You are VERY confused and have missed a basic point of SR.
We CANNOT ascribe any sort of "absolute zero" to ANY speed/velocity, just like
there is no "absolute rest".
Newton got it wrong, and we have known this for over a century.
Remarkably, the equations Newton derived assuming his absolute
space work equally well using any inertial frame, without any
reference to "absolute space". (The very same thing happened
to Maxwell's theory of electrodynamics.)
For some phenomena there happens to be SET OF COORDINATES to which we normally
refer its speed:
* a wave in a medium is normally referenced to the inertial frame
in which the medium is at rest.
* an automobile is normally referenced to the inertial frame in
which the LOCAL surface of the earth is at rest.
It has become ingrained in our psyche to use inertial frames.
It is also ingrained to use those normal frames for these
specific phenomena. Indeed if one uses anything else it is
incumbent on the author to explicitly mention it.
There is NOTHING "natural" here [#], except humans' natural desire to make the
calculations easier.
[#] I.e. Nature is neither involved nor consulted, and does
not care which choice is made.
But for most phenomena, including light and all massive and massless particles,
there is no such "normal" coordinate system, unless the physical situation
provides one [@]. For instance, we can refer the speed of photons to the
inertial frame in which their source is at rest, or we can reference to the
inertial frame in which the detector is at rest -- the choice is OURS, and we
generally select the coordinates which make the desired calculations easier.
[@] And many experiments do: the inertial frame in which the
laboratory is instantaneously at rest.
Nature does not care which coordinates we use to describe her behavior, because
she clearly does not use any coordinates -- that imposes the constraint on all
physical theories to be independent of coordinates; indeed all of our modern
fundamental theories of physics are so independent (aka "invariant").
Note that in all cases there is NOTHING to prevent us from using some other
coordinates, it's just that in such cases as mentioned above there is a specific
coordinate system relative to which the calculations are easier.
> The movement of a body, e.g. a car has not such absolute zero. We may refer

Yes. ALL such choices are arbitrary, for any phenomenon.
Being humans, and therefore lazy, we generally use this
arbitrariness to select coordinates that make the calculations
easier. Nature has nothing to do with this.
The exceptions you claim above are not really exceptions, it's just that you
don't understand this.
> In case of acoustic waves in air, we needn't construct coordinates in which

Right! See above.
In another post to Poutnik you said:

Nope. It is YOU who is confused, not Poutnik or me.

> train are the reference.
Yes. That arbitrariness is INHERENT in the physical situation. One could also
choose the inertial frame of the tracks. Or any other frame....

One must CHOOSE to which coordinates one references any speed. For sound it is
so ingrained in our psyche that one must explicitly mention using any
coordinates other than the inertial frame in which the medium is at rest. Since
you did not mention any such frame, then "speed of sound" of course refers to
the inertial frame in which the medium is at rest.
You confuse a human convention of speech with physical law.
That's outrageous and merely demonstrates how confused you are.

There is NOTHING "natural" about this, it's just that it is EASIER to use those
coordinates. The choice is indeed ARBITRARY.

[https://www.npl.washington.edu/AV/altvw38.html]
Note the context here is SR.
While this article is not wrong, it does use archaic terminology and simple but
potentially misleading phrases intended for non-experts (e.g. "the object's mass
increases").
To me, "the" explanation of the twin paradox is obvious, once one understands
relativity and the underlying mathematics:
The elapsed proper time of a timelike path between points A and B
(which lie upon it) is \integral d\tau, where \tau is the proper
time of the path, and the integral is taken along the path from A
to B. For multiple paths between A and B this obviously depends on
the path. Moreover, the inertial path between A and B has the
largest elapsed proper time of all timelike paths between A and B.
Exercise for the reader: prove that if there is any timelike
path between points A and B, then there is a unique inertial
path between them. (This is SR; in GR there exists at least
one inertial path, but it need not be unique, and in general
they have different elapsed proper times between A and B.)
This is a direct analogy to a triangle ABC in the Euclidean plane: The triangle
has two paths from A to B (AB and ACB) that clearly differ in length. The twin
paradox, with instantaneous accelerations for the traveling twin, is just a
triangle in a space-time plane.

underlying it. Their opinions and attempts to write about physics are worthless.

Perhaps, SR is about as basic to physics as was Cantor's naive set theory and is the hyperreal line to mathematics.

There are neither arguments against unicorns in that work. So I don't understand your definition of c as justified. Nonsensical implication ? YES ! The same as yours. Arguments against your definition of c are in physics and metrology. SR is justified by its formal internal consistency that is mathematically proven and by agreement of its predictions with observations. That cannot be said about the common sense. You ignore that. There is no two-way definition of c, so using one-way adjective is redundant. c is defined as 299 792 458 m/s. Do you have other number ? Prerequisite to evaluate SR justification is SR understanding. For now, you have troubles to answer "How to maintain supposed but not verified absolute simultaneity with the verified invariant vacuum light speed ?" What you do is like repeating of a historical claim "Jupiter moons cannot exist." without simple verifying their existence. > The translation of "Eigenzeit" as "proper time" is a bit misleading > because proper means real and satisfactory rather than inadequate. > People use proper time ( even if not calling it like that ) > since portable watches were invented. > They usually consider it real, satisfactory and adequate. The fact that difference between coordinate time interval and proper time interval is negligible for everyday use is lucky circumstance. > > Wikipedia "proper time" illustrates proper time AB as obviously larger > than the belonging "coordinate time" but calculates it as smaller. > This might confuse. No, you have confused length of drawn curve of the object world-line with the length of proper time interval. The space-time interval, defined by 2 events, is independent on passed worldline. As space-like component of space-time interval is minimal for inertial motion, then for this motion the proper time interval is the longest. > Anyway, SR is perhaps difficult to teach to any critical mind. > I don't see questions of mine answered. Teaching critical minds SR is in fact easier. They critically assess they own knowledge, skills and abilities. They do not consider themselves superior out of their area of experience. They do not put their conclusions above experimental evidence. They know common sense often fails out of its experience. Not seeing answers means just that. Not seeing answers does not mean absence of answers.> >> This is a direct analogy to a triangle ABC in the Euclidean plane: >> The triangle >> has two paths from A to B (AB and ACB) that clearly differ in length. >> The twin paradox, with instantaneous accelerations >> for the traveling twin, is just a triangle in a space-time plane. > > Hmm. Isn't AC + CB shorter than AB? You must be joking... The point of this triangle analogy is, that while both twins pass the same space-time interval between events, the accelerating twin passes the bigger space interval ACB of space-time interval Event1-Event2 and smaller proper time interval. > Perhaps, SR is about as basic to physics as was Cantor's naive set > theory and is the hyperreal line to mathematics. If subatomic particles form Cantor-like sets and move along hyperreal-like trajectories, that yes. -- Poutnik ( The Pilgrim, Der Wanderer ) A wise man guards words he says, as they say about him more, than he says about the subject.
