Now, how on earth can we relate a tautology to a basic
definition in math?

>From the top, bottom, middle, and other books in the stack
we get this definition:
--------------------------------------------------------------


A linear transformation, A, on the space is a method of corr-
esponding to each vector of the space another vector of the
space such that for any vectors U and V, and any scalars
a and b,

 A(aU+bV) =  aAU + bAV.
-------------------------------------------------------------

Let points on the sphere satisfy the vector X={x,y,z,1},
and the circle center satisfy C={x.c,y.c,z.c,1}. Let a=1,
and b=-1.

Let A= ( 1   0   0  -ut )
       ( 0   1   0  -vt )
       ( 0   0   1  -wt )
       ( 0   0   0   1  )

A(aX+bC) = aAX + bAC.

      aX+bC  =  (x-x.c, y-y.c, z-z.c,  0  ).


The left hand side:

     A( x - x.c ,  y - y.c,  z - z.c,  0  )

     = ( x-x.c ,  y-y.c,  z-z.c,  0  ).

The right hand side:

       aAX= ( x-ut, y-vt, z-wt, 1 ).
       bAC= (-x.c+ut, -y.c+vt, -z.c+wt, -1 ).
and

  aAX+bAC = ( x-x.c, y-y.c, z-z.c,  0  ).

Need it be said?

Sure:  QED.  On the galilean transform the
definition of a linear transform,

       A(aU+bV)=aAU + bAV,

is completely satisfied.

The generalized form transforms exactly and
non-redundantly - with ONE TRANSFORM, not a
transform and reverse transform - and non-
tautologically, just as the very definition
of a linear transform says it should.

And does so with absolute invariance, with this
galilean transformation.

Subject: 14. But The Transform Won't Work On Time Dependent Equations?

The main crackpot that has asserted such a thing was referring
to equations such as in Subject 4, above. The Light Sphere
equation; for which we have shown repeatedly elsewhere that the
numerical calculations are identical for any primed values as
for the unprimed values.

The presence - before transformation - of a velocity term
seems to confuse the crackpots. It turns out there is ex-
treme historical reason for this, as you will see in the
subject on Maxwell's equations.
