Due to the OP's refusal to acknowledge correct responses and consequent unscheduled vacation, this thread is now closed.
The Lorentz transformation is, by definition, that coordinate transformation which under which the speed of light is the same in all inertial frames, and that's what @Ibix derived in #27 above (Note that his derivation does rely on the two postulates: The choice of a linear map is justified by the first postulate and the second postulate is why we choose the ##A=(1-Ev^2)^{-1/2}## solution over the ##A=1## solution).Enovik said:You article can't to be named as Lorentz transform derivation. It is some formulas derivation without a task statement. Lorentz transform must to follow from two postulates. It must to be confirmed.
But the Lorentz transformation is a transformation of the time coordinate, not of time intervals. There is a sensible coordinate transformation in which the time coordinate is common to all frames: the Galilean transforms used by Galilean relativity, which were taken for granted by all physicists for centuries before Einstein. These do not honor Einstein's second postulate.More than. The time transformation can't to depend on value ##x##. There are common time in all fixed frames.
