I’m reviewing my mathematics knowledge, except I’m looking for a different reason. I understand how it works you know, 1 plus 1 so on, I’m trying to understand why it works. Pure and applied mathematicians and physicists have tied our understanding of reality with mathematics. They believe that if it computes it is real. This will do for a while, till we pose a question beyond our understanding. But that’s for a different time. Why does it work? Any takers?
