Everyone has problems with the Langevin paradox, since for 120 years, no 
one (except Doctor Hachel) has ever succeeded in explaining it and showing 
that the theory of special relativity well explained (and not by the 
physics teachers who teach Minkowski space-time) is simple, coherent and 
logical.
So everyone starts saying anything, explaining anything, and behaving in 
any way.
We arrive at a problem which is more of a religious nature than a 
scientific one, and it is simply incredible. “We don’t want this man 
to rule over us.”
Scientifically, what is happening is simply incredible.
