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.)

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.

you can build a PID controller on analog hardware. Isn't that what Wiener's AA gun was doing? The Soyuz guidance system worked that way until like 2010. Even digital computation is based on an analogy. The 0/1 dichotomy of bits is a special case of transistor behaviour.

Quite the contrary, such models were already implicitly based on the principles of digital computation. You can even go as far as Sputnik 1. Analogue computation is a fundamentally misconceived notion. I'm sure
@dynamic_proxy can articulate the problem far better than me. - 11 more replies
