Bonjour,
Dans la continuité du fil sur les unités et pour ne pas le faire inutilement diverger, voici un extrait d'un interview de Judea Pearl sur l'absence problématique de causalité dans les équations mathématiques de la physique :
Why are cause-and-effect relationships so critical—and so misunderstood?
They are misunderstood because science was not kind to us; it has not given us a language to deal with them. Take the connection between the barometer reading and atmospheric pressure. We know that atmospheric pressure affects the barometer reading, not the other way around. If I fiddle with a barometer, the weather wouldn’t care a bit. Yet, as strange as it sounds, we cannot express this obvious fact mathematically. If you try to put it into an equation, the equation will deceive you. Equations just tell you that if you know some quantities, then the next one is determined—but you don’t know which affects which, because the equations of physics are symmetric.
