The Bayesian Second Law of Thermodynamics

I post occasionally about Bayesian probability, particularly with respect to Bayesian inference, and related applications to physics and other things, such as thermodynamics, so in that light here’s a paper I stumbled across yesterday. It’s not a brand new paper – it came out on the ArXiv in 2015 – but it’s of sufficiently long-term interest to warrant sharing on here. Here’s the abstract:

You can download the full paper here. There’s also an accessible commentary by one of the authors here.

The interface between thermodynamics, statistical mechanics, information theory  and probability is a fascinating one, but too often important conceptual questions remain unanswered, or indeed unasked, while the field absorbs itself in detailed calculations. Refreshingly, this paper takes the opposite approach.
