Thanks for waiting. Here is today's message from me:

"A little general equation for these relativistic deformations is:
(t'/t * j'/j * k'/k)/(i'/i) = 1,
in which each expression is the algebraic symbol for the ratio of size
of “one unit” of the viewed system compared to “one unit” of the
viewing system.
"Since ø = j'/j = k'/k and  = i'/i; this reduces to
t'/t * ø2/ = 1. Since  always equals qø, this too can be reduced,
becoming: t'/t * ø/q = 1; or, therefore,
ø = q.
"Since this reduction eliminates an essential ingredient in these
deformations, however, such a step is a mathematical trap for the
unwary. Other than during calculations, needed symbols should never be
rendered invisible; even and especially if they happen to sometimes
equal 1. (Whereas both Lorentz and Einstein tried to prove that l =
ø(v) = 1, Lorentz later abandoned l = 1 as a general value.) Even
though in all these cases  = qø and ø(t'/t) = q, the numerical values
of these deformation-ratios cannot be mathematically derived until
that of at least one of the others is stipulated." From A Flower, and
some of my prior books.

Other than that the symbols in the general equation are boldfaced
(to indicate that they are vector quantities), I will now convert the
above math into a form that can be understood via these verstunckena
newsgroup versions.

A little general equation for these relativistic deformations is:
(t'/t * j'/j * k'/k)/(i'/i) = 1,
in which each expression is the algebraic symbol for the ratio of size
of “one unit” of the viewed system compared to “one unit” of the
viewing system. Since
phi(v) = j'/j = k'/k = dy'/dy = @z'/@z, and
 = i'/i = dx'/dx,
this reduces to
t'/t * ø2/ = (dtau/dt)phi^2/(dxi/dx) = 1.
Since  always equals qø = sqrt(1 - v^2^/c^2)phi(v);
ø = phi(v)(dxi/dx) = q.

The penultimate step: In P1 E was doing deformations, with K (x,t)
moving at v. In P2 he tried to let x,t be stationary with xi,tau
moving at –v; as in Poincare's Sur la Dynamique.

The final step to eq 7: Returning to the format of Voigt and Lorentz,
he let BOTH systems move at v!

Given THAT plus my little equation, i will let you fill in the
details. If nobody can, I will do it for you in another day or so.
Meanwhile, here is another morsel for you to contemplate:
"As the special theory of relativity so catastrophically
demonstrated, mathematics permits operations that the physical problem
at hand does not. The result is that the resulting equations then
quite accurately say things that neither the mathematicians nor
physicists understand. The catastrophe isn't that we don't understand
the resulting equations, but that we think we do!" From "The
Universe".
