Ahem....

"If we place x'=x-vt, it is clear that a point at rest in the system k must
have a system of values x', y, z, independent of time. "
http://www.fourmilab.ch/etexts/einstein/specrel/www/

NOTE... "IT IS CLEAR". Einstein said so and unless you think the length
of a train will change overnight, is is very clear.


| Note that there is a minor error in the paper,

Yes, there is a MAJOR error on the paper. Several, in fact, the first being
the so-called light postulate for which there never was any physical
foundation,
the next being the time postulate and the stupid assumption that the speed
of light is measured from A to A in time t'A-tA instead of from A to B in
time t, from which comes "the velocity of light in our theory plays the
part,
physically, of an infinitely great velocity."
Einstein plays the part of con-artist gigolo and you play the part of a
Neanderthal troglodyte pretending to be a ghost. I play the part
of a slave and Dork plays the part of himself, he can't even spell his own
name.

I didn't find that, you are seeing double.

My question was to Dork. He thinks x' = xi, but one would expect that
from a moron.

It is quite clear that
xi = beta(x-vt) = beta.x'
