What fun (don't people ever read?!):





And I know what I can and what
I cannot measure. And I know that I can measure the
relative velocity of any light or any radio signal or
any other such signal as it might be going past me,

Yes.

or a train, or a plane or a moon or a planet or a
star or any other inertial reference frame.

No. You can deduce it, but you must use the proper prescription for
deducing it. If you us a prescription that relies on subtracting or
adding two displacements and a common time, then you are assuming that
the velocities combine as c+v or c-v, and that is simply wrong.

These
things are possible, and I know that my measurements
(I am not sure about your measurements), but my
measurements will be SR correct,

Not the way you've described them, they won't. If you end up with c+v
or c-v, that is not "SR correct".

That happens to be a literal part of Einstein's SRT derivation.

I am completely familiar with that paper, both in English and in
German. I am not implying that the 1905 paper is incorrect. I'm
implying that some people do not understand what they are reading.

So, you
imply that Einstein's 1905 paper is not correct according to SRT. But in
fact, that *is* "SR correct", there is nothing wrong with it (eventhough you
and Androcles think so).
