It's not the mathematical basis of SR. The postulates are the basis of
SR. The Lorentz transform was *derived from* these postulates by
Einstein, not the other way around. It is a mathematical *by-product*
of SR, as are a number of other mathematical by-products. Calling the
Lorentz transform the mathematical basis of SR is like calling bacon
the basis of a pig.

No, Larmor did not derive it from the two more fundamental postulates.
If you have a reference that clearly states otherwise, then I'd be
glad to have it.

I understand that's your opinion. You think it's the Lorentz transform
that's more fundamental than the postulates. That is an opinion that
is not commonly shared. Physicists generally agree that the two
postulates are the underlying physical facts that have more
fundamental importance, and in fact those postulates have had broader
and deeper impact than the Lorentz transform ever has.

However, I also understand how immovable your opinion is. That's not
uncommon in someone retired, where the ability to reform one's
thinking is reduced.

Please elucidate clearly the errors you believe are there. I take it
you found no errors in the derivation of the Lorentz transform from
the two postulates.

No, it is not due to the religion of SR and GR. It is how science is
done in general. I also cited examples of QCD and the theory of the
weak interactions, which do not stem from SR or GR. I could also point
to similar examples of association of credit with thermodynamics in
the 19th century, or quantum mechanics, or optics.

As I said, your metrics of assigning credit in science are not
commonly shared.

Your ignorance of how to do that is not an indicator of its falseness.
It's only an indicator of your lack of experience and exposure.

Sorry, again, your view is one that is not commonly held. There are
often multiple ways of solving a puzzle. Even an Atwood machine can be
solved by using Newton's 2nd law, or by potential and kinetic energy,
or by using a Lagrangian. And though it isn't obvious to the beginning
student, each of the three solutions can be derived from each of the
others. Your desire that there *should be* one and only one resolution
to a puzzle is simply not commonly shared. You can consider yourself
singular in a number of respects.

The principle of relativity says that the form of the *laws of
physics* are invariant regardless of the inertial reference frame. It
does NOT say, for example, that the quantities that appear in the laws
of physics will be the same in every inertial reference frame. It does
not even say that qualitative statements of conditions (e.g.
"simultaneous", "before", "after", "stopped", "moving") will be the
same regardless of inertial reference frame. Any extrapolation beyond
what the principle of relativity actually says is likely to land you
in error.
