For my Djippy...

My dear Jean-Pierre,
I would like to point out to you that I am still waiting for your proof that my relativistic concepts are not correct.
I told you a thousand times that relativistic physics was a correct science, but poorly taught, and that you couldn't do anything about it.
You caused me a lot of pain by taking my considerations as a joke.
You still haven't understood that Doctor Hachel is currently the world's best theoretician regarding relativistic kinematics.
I remind you my dear Jean-Pierre, the equation Vapp=v/(1+cosµ.v/c) specific to the determination of an apparent speed (radial speed).
You still haven't answered me (and that's not good), on the question I asked, what will be the apparent speed of approach and the apparent speed of escape, of a mobile moving at v=0.8c?
Vapp'(leak)=
Vapp"(approach)=
It's not good to be afraid. Fear does not ward off danger.
While you're at it, give me your opinion on the Hachel transformations proposed for rotating environments. You are perfectly familiar with the Poincaré-Lorentz transformations for Galilean environments,
what do you think of Hachel's for rotating midfielders?

Thank you, Jean-Pierre.. You are a darling.
