one question at a time, let's simplify the point since you're clearly
lost from the very beginning :

n'=t(1-v/w)

Well. In frame A, I consider two light rays on the (Ox) line (does it
remind you something ?). One at speed w=c in A, the other one at speed
w=-c in A. How would an observer in B would compute, in the context of
you "theory", using n', the speeds of both light rays simultaneously ?

OK, say that the lights are emitted at -a and a in both frames of
reference when the origin of B is at the origin of A, each ray of
light directed at the origins. B is moving in the +x direction
relative to A at a velocity of v. The light ray emitted at -a has a
velocity of w=c in both frames of reference. The light ray emitted at
a has a velocity of w=-c in both frames of reference.


The light ray
emitted at -a goes from x=-a to the origin of A in frame of reference
A in a time of t=a/c. The light ray emitted at -a goes from x'=-a to
the origin of B in a time of n'=a/c. The light ray emitted at a
travels from x=a to the origin of A in a time of t=a/c. The light ray
emitted at a travels from x=a to the origin of B in a time of n'=a/c.

Funny : the same light rays have a different behaviour in A and in B !
Here is what you pretend:
They meet at the origin of A from the point of view of A (so the bell
ring)
They meet at the origin of B from the point of view of B (so the bell,
which is NOT at the origin of B at this time, doesn't ring)
AGAIN: This is a direct conclusion OF WHAT YOU JUST WROTE, not what
I pretend, not what GT or LT pretend.

The equation for n' is

n'=t(1-v/w)

You remember the equation for n', YBM.

Is there some kind of magic making its clock change whenever he consider
one light rays or the other one ?

It is not a transformation equation, YBM. It just tells how far light
has gone in B according to a clock that shows n'.

You way you evade questions is ridiculous...

FIRST : they is two light rays in the experiment, SO there is two "n'" :
n'=t(1-v/c) (for light ray coming from (-a,0,0))
n'=t(1+v/c) (for light ray coming from (a,0,0))
Why should the observer in B use two clocks, both of them
being broken ?
SECOND : You have a double language : You claim that n' give
a time coordinate for obervers of events in B, so the
equation for n' is part of a transformation (the fact
I've proven is that this transformation is absurd), then
you claim that this equation is NOT a part of a transformation,
but then you just support Galilean Transformations were
speed of light rays in frame B is no more c.

By the way, next time you'll pretend I've proven something, please
don't lie and write that I've proven Robert Winn's modified
"Galilean Transformation" to be absurd.

Robert Winn's best fumble :

> of B

so... the ring bell in B but not in A (the bell is not at the origin
of B whenever the light rays meet !)
