Episode notes

We would like not to use a statistical mechanics methods, because this leads to an emergent set of laws which is somehow only approximate and not really fundamental. And there you can see that there is a compatibility between those statements and the fact that the dynamical trajectories of elementary constituents, of the objects that obey these general s are actually comdea smetric. Ok a, this sounds, this sounds a worth trying to do, but still a little aspirationallike, we don't have the full story yet played out. I thing that thats er thers correct. Ande, it is quite exciting, i sink. Another thing that er currently am focson.

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.
