Abstract
What the reality is and what it is described in theory or model is not one thing. What we use and understand is just a model. For answering this question in a model, we have two ways: to include them in basic hypotheses or deduce them from basic hypotheses. I’ll try to check the two approaches. Further more, what we see in macroscopic scale is absolutely analog. If the answer in the model we use is digital, I want to know how could digital units form an analog representation.
