My current experiment in writing my book is explain how TTL is based on first principles, something I was trying to get it in my post The Experiment-Driven Life Universe v0.1. The first one, the world is constantly changing, leads to the question, "Why?" What is it about the world that makes it change? Is it the common interpretation of the Second law of thermodynamics, that is, the universe is always in motion towards equilibrium (put very roughly)? I'd love to hear your thoughts.
