Why no, Ken, isotropy is still the same.

The track observer notes:
The light from the front of the train is heading backwards at c, while
the train observer rushes toward that light at v.
The light from the back of the train is heading forwards at c, while
the train observer is receding from it at v.
The speed of light is c in both cases. It is still isotropic in the
track frame.

Hey idiot....that's not what Einstein said. He said that:
1. the train observer rushes toward the light front from the front and
thus it takes less time for that light front to reach him.
2. the train observer recedes away from the light front from the rear
and thus it takes more time for that light front to reach him.

This means that two different transit times for two light fronts
generated at the same distance from the train observer and thus the
isotropy of the speed of light is not preserved by Einstein's
assertion.

O help.... all that trouble PD went through.
Would there be *anything* Seto understands all by himself?
I seriously doubt it.
Perhaps Androcles should try to explain the concept of
closing speed to Seto.
That would be highly interesting, if not wildly amusing.
Gasp.
