E: Listen up, Androcles, I am not one of the True Believer SR-cult cretin
shits who treat you so shittily.

A: Ok, listening up.

E: Answer these question so we can preceed to your thesis on solid ground.
If you think my implied suggestions is wrong go back into 1905 and see what
it says.

E: A. AE intended x' to be a poitive constant, moving system value, the
distance of the moving mirror from the moving origin.

A: Defined by x' = x-vt. Some sample values
x' x v t
-2 -1 1 1
 1 0 -1 1

E: B. he set v positive (or zero)?

A: It should be able to take any value. Actually it can only take zero.

E: C. it is t>=0 we should pay attention to?

A: Time doesn't run backwards.

E: D. if x' is positive (a distance, length) and so are v and t then x must
be
 positive also?

A:
 x' = x - v*t
 2' = 3 - 1*1
 1' = 2 - 1*1

-------0------1------2------3------4------5
----------------------|< vt >|
---------------0'-----1'-----2'-----3'-----4'-----5'

 1' = 3 - 2*1
0------1------2------3------4------5
----------------------|< vt >|
---------------0'-----1'-----2'-----3'-----4'-----5'

Never mind my abrupt nature. It's just the way I come across.
Androcles.
