Wigner wondered about the unreasonable effectiveness of mathematics in describing our universe. That is, why are our physical laws as described by precise mathematics produce predictions that turn out to be true? Let’s look at it from three perspectives. #1 We grasp the graspable bits By definition, we model aspects of reality that we are capable of modeling. The remaining part may be truly random or complicated. For example, where do quantum measurements come from? Or the incompatibility between general relativity or quantum mechanics. We hit the limits of our models in those cases, so it’s a bit of survivorship bias when we ask ourselves why our models work so well in cases where do they do. #2 The Anthropic Argument Out of all universes that could exist, the universes in which any science is possible upper-bounds their complexity (if universe were any more complex, no science is possible as laws would be too complicated and Winger wouldn’t be asking this question). The lower bound…
