Very nice explanation of free energy in statistical physics. Please note that this is not the variational free energy used in approximate Bayesian inference (or related theories of brain function). For some thoughts how these might be related please see https://kaiu.me/2019/10/09/life-and-the-second-law/ ….https://twitter.com/johncarlosbaez/status/1200473111029698560 …

What's "free energy"? I don't mean energy you get for free. I mean the concept from physics: roughly, energy that you can use to do work.
More precisely, free energy is energy that you can use to do work at constant temperature. But why the fine print?
