Links after notes on our talk: tightening up a definition of entropy and exploring computational theory and emergence and their underlying implications. When anomalies show up, a new physics is needed. Entropy is more qualitative than quantitative. No creativity without entropy. It takes excess energy to get things over the hump and energy to create order and to maintain order. You can only play the deconstruction game once. Irreversibility is a fundamental aspect of the universe. The universe is fundamentally irreversible. The 2nd law is not driving time but is a consequence of that. The laws of physics appear to be reversible, but is that just a function of the continuous and differentiable functions that physics is using to do the calculations? Physics is always creating mathematical models that describe what we see in the universe around us, not what it is actually doing. Computation: the simplest system is a finite state machine. The memory of the past is gone. Shows irreversibility in computation. Landauer's principle, Landauer's eraser. When you go through a logic gate, you lose information and entropy has gone up. Transistors need to be in a very specific order to be useful. Emergence crosses a barrier when something complicated becomes simple again.
