Whoah... so many errors in the formulation of your question.
Yes, "seems".
Ok, so both are ON the x axis. The usual config.
? Now you mean that they are both NOT on the x axis but on parallel
lines *to* the x axis?
? They are a distance L in which frame, the "initial" frame you
referenced or this new frame V ? make up your mind.

Re: Chapter: The mechanisms behind Non-Simultaneity

Hi, Androcles
Both your expressions are equally well valid.
It should be noted that L and L0 do not contain the same set of
events so the formula only serves to determine the correct measured
length of a static non-changing object.
If the object changes over time then you need the first expression
to determine the correct length at a certain time t.

Riedt vs Einstein
Einstein's first postulate of Special Relativity (Principle of
Relativity): The laws of Physics are the same in all inertial systems.
No preferred inertial system exists.

No it isn't that at all.

Hey idiot....in IRT the speed of light is a constant ratio in all
inertial frames as follows:
Light path length of ruler (299.792,458m long physically)/the absolute
time content for a clock second co-moving with the ruler.
No it doesn't work at all....it violates the isotroppy of the speed of
light in the train.

This is not a principle.

A logical proof is not required. However, experimental proofs are required.
Untrue.

Incorrect and the rest of this post is wrong.

Three Observers get together. Two on the embankment and one on the
train. One Observer is at A and on Observer is at M on the embankment.
The Observer on the train is located at a point between M' and B' on
the train. I will call this location C'. The experiment is setup so
the light from A will reach the Observer at M and the Observer at C'
