Just a few questions that are really confusing me... 1. Where is the cut off boundary between the existance of Quantum mechanics and Classical mechanics, is there a specific point where classical takes over from quantum and if so where is that point? 2. Is the micro quantum world indeterministic and the macro classical world deterministic or is the macro classical world inherently and fundementally indeterministic as well? 3. If the quantum world works on probability and without causation then wouldn't the classical world also work on probability and without absolute causation, or in order words there would be no way to make 100% accurate predictions on things in the macro world. 4. How does the randomness of the quantum world create structure and order in the classical world? Any help or info is massively appreciated, thanks.
