And your point is?

When a proton moves around the circuit once, a stationary clock
in the circuit will measure the one round around the circuit to
last the time T = 90.0623 μs
The proton (if it had a clock) will measure the one round around
the circuit to last the time τ = 12.0727 ns
 Does this mean that when the proton moves around the circuit once,
then it moves once around the circuit in the lab frame while
it moves T/τ = 7460 times around the circuit in the proton frame?
 But no!
 It's stupid.
 Le proton ne fait le tour qu'une seule fois, et le temps qu'il met, mesuré par l'horloge du laboratoire (qui est en fait DEUX horloges A et B réunies en une seule) est de T = 90.0623 μs.
 J'écris To = 90.0623 μs pour dire que c'est le temps observable dans le référentiel du laboratoire.
  Mais si je mesure avec la montre que porte le proton à son poignet gauche, je vais mesurer un temps  de τ = 12.0727 ns.
 Ainsi, pour le proton, la distance AB (dans le référentiel du laboratoire) a été franchi 7460 fois plus vite.  Cette notion, je l'appelle vitesse réelle du proton, même si cela sonne drôle quand on n'a pas l'habitude de voir les choses ainsi.  La vitesse habituellement mesurée, et observée dans le laboratoire, qui est la distance dans le laboratoire par le temps du laboratoire, je l'appelle v (comme les physiciens) ou mieux, Vo, pour signaler que nous n'observons jamais qu'une notion des choses, et non les choses réelles, déformées par la nature de l'espace-temps local, du référentiel local.  R.H.
