Re: the notion of counter-intuitiveness in relativistic physics

It's a mystery to me what "RR" stands for, but your use of the term
"apparent speed" is tenuous.  To me, it means an optical illusion, which
has no place in solving relativity problems.  Velocity is the correct
term, and it is measured as v = (x2 - x1)/(t2 - t1), where t2 and t1 are
read from synchronized chronometers at points x2 and x1, respectively,
as the object whose velocity is meing measured passes those points.

This is a magnificent definition, and its simplicity and truth deserve to be taught in all high schools in the world.
I'm not kidding.
Now once this is taught, and well understood by the students,
they will be able to solve lots of problems with railways or highways, and even be able to time the final of the Olympic 100 meters.
The formula you give is simply magnificent...
BUT...
But then Richard Hachel arrives once again, and his unfortunate habit of behaving like a genius of humanity, and he will say: "You are doing Newtonian physics, guys, very beautiful Newtonian physics, and, in this case, let yourself be taught by Maciej, who also does excellent Nestonian physics. Forget relativistic physics."
In truth, if this equation keeps a certain reality for proper times (tau), it becomes unusable for improper times, unless, like Hachel, we write Vo, and no longer v, in relativistic equations.
Why?
Anisochrony, guys, ANISOCHRONY!!!
In Hachelian relativity (the best theoretician of RR since Poincaré, Einstein and Minkowski thrown in the trash, although I am not anti-Germanic), we cannot add, subtract, count, times with watches even intertial, stationary between them, if they are placed in different places. This results not in a TRUE measurement, but in an OBSERVABLE measurement.
The only true measurement can only be made by a single watch (tau).
I keep begging everyone to understand that TWO different watches spatially separated (universal anisochrony) distort the measurement. When you do:
v = (x2 - x1)/(t2 - t1) it is both very true and very false.
If this is done with the watch of the mobile (which cannot desynchronize with itself), we therefore have, in Hachel notation:
Vr=(x2-x1)/(Tr2-Tr1)
We have here the true speed, and it will give the true quantity of movement, p=m.Vr and the true energy of the body E=mc².sqrt(1+Vr²/c²)
But if we use the time measured by two different watches (be careful, even if the path was circular, the watch that measures placed at the edge of the circuit, it is TWO watches) then we end up with anisochronous murder.
We have Vo=(x2-x1)/(To2-To1) but the observable times being biased by the anisochrony between the two watches, we have an observable measurement which is a decoy and which is not the reality of things.
There is a constant difference between the real speeds and the observable speeds.
Example, Vr=(4/3)c ----> Vo=0.8c
As a relativistic reminder:
Vo=Vr/sqrt(1+Vr²/c²)
Vr=Vo/sqrt(1-Vo²/c²)
