The Central Question
World 15 taught us to count possible structures. World 23 taught us to organize many variables. Now we ask: What do we do when the universe gives us observations instead of exact laws? We must learn to find the signal in the noise, summarizing millions of data points into meaningful patterns, centres, and spreads.

Matrices asked: What is the system? Statistics asks: What did we actually observe from the system? And Probability will eventually ask: What could happen next?
