Yes, ξ(x', Δt₁) = x' is STUPIDLY FALSE, that's what I said above.
But Einstein never wrote that, you did.

You wrote ξ(x') = x' which is even more STUPIDLY FALSE,  because
ξ is a function of both x and t in K.

  :-D

The transform that follows from the postulates of GR contains
the GAMMA FACTOR with mathematical necessity.

It is a _fact_ that the Lorentz transform follows from
the postulates of SR.

This is proven many times by several physicists.
Einstein was the first to do it, but he did it in a rather
cumbersome way which, as you have demonstrated, may not
be simple to understand.
In the more than a century since Einstein did it, it has
been done many times in much more elegant ways which are
simpler to understand.

You can, and do, claim that SR and its postulates are wrong,
and that the vast amount of experimental evidence confirming SR
is made by fraudulent physicist who are members of a MAFFIA.

But you can't dispute the fact that the Lorentz transform
follows from the postulates of SR.

Enough now. Have a nice day.
