Is there anyone around here who doesn't belong to the overcrowded family of Universe Creators, and simply aims at a humble extension, as far as possible, of Classical Mechanics?
I’ll be the first one to reply to my own question.
My humble Universe is simply ruled by the centuries old "Ockham’razor" (further known as "the law of parsimony") stating that "simpler solutions are more likely to be correct than complex ones". The idea is attributed to the english franciscan friar William of Ockham (1287–1347), a scholastic philosopher and theologian (see WIKIPEDIA).
I’ll refer to the recent paper presented on ResearchGate by A. Orefice, R. Giovanelli and D. Ditto: De Broglie-Schrödinger Single Particle Trajectories,
DOI: 10.13140/RG.2.2.16385.10084/4 .
Here the problem of de Broglie’s “Wave-Particle Duality” is simply reduced, by inspection, to a “Railway-Train Duality”. Any moving particle is addressed, in fact, along the stationary wave-vector lines of the wave described by the relevant time-independent Schrödinger equation. Do you find this odd? Well, SQM is odder.
