a)      Train observer M’ on frame K’ sees two simultaneous strikes at t’ =
1/3 sec, x’ = 0.
b)      Track observer M on frame K sees two non-simultaneous strikes, the
first at t = 0.167 sec, x = 0 and the second at t = 0.667 sec at x =
0.

We notice that both observer disagree about the strikes being or not
simultaneous and both are right in their observations (neither K nor
K’ frames are preferred frames).

This proves the relativity of simultaneity.

Your math proof is based on a bogus model of the prpagation of the
light fronts. This bogus model is in turn based on the false
assumption that the same two light rays that arrive at M will continue
on to arrive at M' which leads you to make the bogus conclusion that
the train observer sees the front light front before he sees the rear
light front. This is wrong. The two light rays that hit M are absorbed
by M. Two different light rays from the...

Your bogus answer is based in your inability to grasp and the
ignorance of the Einstein thought experiment.


What is there to grasp??? Einstein said that the train observer M'
will see the flash from the front before the flash from the rear. If
the train observer sees that then he will not be able to measure the
speed of light in his frame to be isotropic. The up shot of this is
that either the constant isotropic light speed postulate is wrong or
the concept of RoS is wrong.....they can't both be right.

Your assertion that strike light signal are lines is ridiculous,

No I didn't assert that at all....Einstein asserted that. I asserted
that the light flashes are light spheres. Two light rays of these
spheres arrive at the track observer simultaneously and two different
light rays arrive at the train simultaneously.

so is
your conclusion that follows.
You are also unable to understand that Einstein put the thought
experiment in simple words, and that it also works when the train
observer is moving towards the direction (x1, y1, z1), because the
light signal propagates in a sphere.

Einstein and you failed to understand that relative motion and
direction of relative motion has no effect on the measured isotropy of
the speed of light in the train.

You do not understand the space-time diagrams either, which clearly
show what observers and light signals do.
Finally you do not grasp the concept of relativity, which is the main
subject of the thought experiment.
