The idea that there is such a thing as analogue computation is a classic oxymoron. The logic of the digital is computation and vice versa. (Now let's see how quickly this thread devolves.)

okay, so what is an analogue PID controller doing then, exactly, if not computing differentials and integrals?

That's the problem. You are already modeling the said controller on digital computation.

I don't see how that is, though? there's nothing "digital" about differentiation or integration, they're both just limits. just like e is a limit and not its digital representation, and can be computed digitally _or_ analoguely

You seem to confuse between two things, math modeling and computational modeling. Math modeling is not computation in any meaningful sense.

Without notions such effectivity (weak or strong) and computational complexity constrains, you are not talking about computation at all.

Similar query. I have watched you refer to complexity science constraints (always both positive & negative, ofc) several times in seminars—& yet I have never seen you elucidate what such constraints might entail, in any context. Reading recs? Examples?

Sure. What counts as the canonical def. of a complex system these days is what you might call statistical complexity or structural stability. There are many formalizations for it but one of the most adequate ones is Ellison-machine reconstruction, so what is it?...

Sorry epsilon, autocorrect fault.
