A rule of thumb seems to be that a quantum equation converts to its classical correspondent by replacing h (Planck's constant) in the former with zero for the latter. What do you think about the possibility for a(adsbygoogle = window.adsbygoogle || []).push({}); continuumof intervening equations, wherein h eventually decreases to zero? Would this suggest mathematical states of decoherence, or of any physically viable phenomenon?
