It is a FACT that according to SR, the speed of
an object with constant proper acceleration A is:
 Vri(t) = A⋅t/√(1+(A⋅t/c)²)

 ? ? ?
 Vri(t)=a.Tr
 Voi(Tr!!!)=Vri/sqrt(1+Vri²/c²)
 Voi=[1+c²/2ax]^(-1/2)
 To=Tr.sqrt[1+(1/4)Vri²/c²]
 

 Note that:
  Vri → A⋅t when t → 0
  Vri → c   when t → ∞
 The average speed Vrm at the time t is:
Vrm = (integral from t=0 to t=t of Vri(t)dt)/t
Vrm = c²⋅(√(1+(A⋅t/c)²)-1)/A⋅t
 Note that:
  Vrm → A⋅t/2 when t → 0
  Vrm → c     when t → ∞

 No.
 Vrm → ∞
 Vr is not Vo.

 So:
  Vrm/Vri  → 1/2  when t → 0
  Vrm/Vri  → 1    when t → ∞

 No.

Physicists do not differentiate between Vo and Vr.

 Because there is no such difference.

The "large majority of physicists" are obviously much more
intelligent than average. They have to be to pass the exams.
(I am not a physicist.)

 Yes, they have to take exams.
Like everyone.
Personally, I'm happy to be theoretically logical and experimental in racing.
This is NOT the current condition of physicists.
Their theory is imperfect and contradictory (Vapp in Langevin), it is refuted by experimentation (their Sr is local, but not mine).

A bit like in Nazi Germany everyone believed they were right because everyone held out their arm in front of Hitler.
Physicists are educated, but very few are intelligent.

 A hysterical reaction!

 No. In SR, is fact.  Ils ne comprennent pas ce qu'ils disent, ce n'est PAS normal.

On usenet, there are perhaps five or six people with whom we can seriously discuss relativity, without immediately falling into hysterical reactions. (Julien Arlandis, Michel Talon, Paul B Andersen...). The others not only learned anything, but answer nonsense when asked a simple problem.
 

 Above you have demonstrated that you belong to the group that
falls into hysterical reactions.

Don't worry about my reactions.
Simply ask yourself: “Is this man lying, or is he telling the truth?”
