In Paris length contraction is NOT REAL; rather, "il s'agit d'un effet
de perspective spatio-temporelle":

Gilles Cohen-Tannoudji: "Chez Poincare, la contraction des longueurs
et la dilatation des durees sont reelles.....Chez Einstein, la
contraction des longueurs et la dilatation des durees ne sont pas
reelles: elles sont le resultat d'un effet de perspective."

Thibault Damour: "La <<contraction des longueurs>> avait, avant
Einstein, ete consideree par George Fitzgerald et Hendrik Lorentz.
Cependant, ils la consideraient comme un effet <<reel>> de contraction
dans l'<<espace absolu>>, alors que pour Einstein il s'agit d'un effet
de perspective spatio-temporelle."

In Oxford length contraction is REAL, particles REALLY "get closer
together", that is, il ne s'agit pas d'un effet de perspective spatio-
temporelle:

"There are many things I might be asking when I ask someone to explain
length contraction. I might be asking, "Why do different inertial
observers (who are not at relative rest) disagree about the length of
a given (inertially moving) rod?" Or I might be asking, "Why is a
moving rod shorter than its stationary counterpart (of the same proper
length)?" Or I might be asking, "If you take a rod that is initially
at rest (in your frame of reference), and accelerate it, why is it
shorter after you accelerate it than it was before you accelerated
it?"......I'm not sure what Brown thinks about geometrical answers to
the first why-question, but he certainly thinks that GEOMETRICAL
ANSWERS TO THE SECOND TWO WHY-QUESTIONS ARE BAD EXPLANATIONS. He
thinks that good answers to these questions say something about the
way in which the forces holding the parts of the rod together depend
on velocity of the rod. Only that is a story of what causes the
particles to get closer together, and so what causes the rod to
shrink."

At first sight, length contraction in Paris is different from length
contraction in Oxford but that is not the case. Il s'agit de DIFFERENT
INTERPRETATIONS of length contraction within the Anglo-French Silly
Walk called "La Marche Futile":
