"In the book "Relativity Einstein's Lost Frame" Rodrigo de Abreu and
Vasco Guerra make a profound investigation on the physical meaning of
Relativity Theory. They show that this theory is compatible with the
existence of a privileged frame, which they named Einstein's Frame,
and enlighten why it is sometimes stated that relativity theory
"demonstrates" the non existence of this frame. In fact, as it is
shown, this is a misconception, a wrongly formulated problem.

Einstein and Infeld in the book "The Evolution of Physics" stated: The
formulation of a problem is often more essential than its solution,
which may be merely a matter of mathematical or experimental skill. To
raise new questions, new possibilities, to regard old problems from a
new angle, require creative imagination and marks real advance in
science. It is in this sense, on the search for a new perspective,
that the old problem of interpreting Lorentz Transformation is
reopened.

Einstein stated that the speed of light in one direction ("one-way
speed of light") is the same in all frames; the fundamental idea
developed in the book is that the speed of light in one direction, is
indeed undetermined, that is, that Einstein's Frame - the frame in
absolute rest - is not known. Interestingly enough, in his famous
1905's article "On the electrodynamics of moving bodies", Einstein
starts by defining distinctly the frame in absolute rest.
Nevertheless, he then gets rid of it, stating that any inertial frame
can be taken as the rest system.

Thus the subtitle "Eistein's lost frame".

The authors show that the "speed of light" as defined by Einstein (the
speed according to the definition introduced by Einstein in his 1905's
article) is indeed the same in all directions, in all inertial frames.
However, the real speed of light is only the same in all directions,
when considered in one particular frame, precisely Einstein's frame.
By having this problem of language pertaining to these two different
concepts of "speed" resolved, the physical interpretation of the
theory becomes, as it is shown, surprisingly simple to make.

The experimental determination of the speed of light "one-way", will
complete this theory, as it will finally allow to identify "Einstein's
Lost Frame". This is the theme developed in chapter 6 "The quest for
Einstein's frame", where several determination methods are referred,
and in particular the reinterpretations of the experimental results
that emerge from the analysis of Reginald Cahill and Maurizio
Consolli.

The theory of relative movement emerges from introducing "Lorentz
Transformation" that is obtained with great simplicity from
"Synchronized Transformation" [#] using a possible clock
desynchronization deriving from this last transformation. This method
of obtaining the Lorentz Transformation is then linked and interpreted
in a precise and simple manner, with Einstein's method. "

No he didn't.

Einstein clearly stated
"But the ray moves relatively to the initial point of k, when measured in
the stationary system, with the velocity c-v, so that

Look it up.

Why do you spamming bastards continue to LIE about what he said?
