OK:
O- origin of x axis in IRS nr 1
O'- origin of x' axis in IRS nr 2
x=x'=0 when t=t'=0 that is when the light is emitted in both
directions
v -is the relative speed of the 2 IRS i.e. of the O and O' origins
ox and 0'x' should be understood as overlaping lines, though
they are shown as separate for a clearer view
On the other hand :
!!! The posting was not meant as an introduction to the subject !
It was intended for clarifying a relatively subtle aspect of
the Lorentz transformations, rarely mentioned in discussions in this
group or elsewhere.
