... Let us try to model a hydrogen atom as a simple classical mechanical system. It is assumed to have an infinitely heavy point-like nucleus that exerts a radially inward directed force of magnitude g on a point-like electron of mass m. Suppose further that an experiment told us that the angular r2 mom ...

Due to the probabilistic interpretation of the matter wave, the notion of “existence” of a physical entity, at its most fundamental level, begins to deviate from our conventional wisdom The existence of an entity is now no more be deterministic notion (e.g. it either exist or not at all) but only ...
