Episode notes

There is an interesting connection between a set of states you can use to perform what, informal is called useful work in termodonamics. And it's interesting that it doesn't er to prove this result. You don't have to appeal to any scale related considerations of your seems like this statement is a free of the problems. It would be interesting to investigate whether the second low connection could be somehow rooted into this other connection. This is an open problem, which im n thinking about right now.

Traditional physics works within the “Laplacian paradigm”: you give me the state of the universe (or some closed system), some equations of motion, then I use those equations to evolve the system through time. Constructor theory proposes an alternative paradigm: to think of physical systems in terms of counterfactuals — the set of rules governing what can and cannot happen. Originally proposed by David Deutsch, constructor theory has been developed by today’s guest, Chiara Marletto, and others. It might shed new light on quantum gravity and fundamental physics, as well as having applications to higher-level processes of thermodynamics and biology.
