Please excuse a brief digression from my ongoing and otherwise purely journalistic, rote scientific essay into Quantum Physics.
I have been convinced for about a decade that the mysteries of quantum mechanics,e.g., the "spookiness" of entanglement, do not conflict with the observable nature of our daily reality.
When we study by the behavior of phenomena that are in their own turn composed of practically infinite constituent phenomena, we are studying the borderline where Quantity becomes Quality. Interestingly enough, Friedrich Engels wrote much the same thing 125 years ago!
