Quantum Mechanics from Periodic Dynamics: the bosonic case
... periodicity is too fast, the system can only be described statistically since at every observation it turns out to be in a random phase of its apparently aleatoric evolution. This is just like observing a timekeeper under a stroboscopic light [12] or a dice spinning too fast to predict the result. I ...
