Episode notes

You can't capture all of the other possible dynamical laws that you could use in order to describe it er. You would need those danomical laws, but to explain all o their features, you would have to appeal to these more general statements about what's conserved and so on. And perhaps a good example here, er has also to do with a the information principle that you can construct witn constructe theory. Yet, no, we can be do want to dig into this one a little bit more, because i may or may not have understood what you said?

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.
