Someone apparently never used calipers or slide rules.https://twitter.com/NegarestaniReza/status/1248950988695842820 …

Calipers provide the input for, and slide rules perform analog computation. The history of computing didn't start with computers.

The Antikythera Mechanism, for instance, is an orrery that dates from ca. 100 BC. An orrery is a computer, even if analogue.

It is but it is precisely because a model within a model, in the sense that the structure of the model and its fidelity constraints (range of interpretations) can be interpreted with a computational model in a modern sense. You can say the same thing about a dam.

Your orrery example is good because it brings up a more interesting question in the realm of modeling, which is the difference between algorithmic models and physical models such as for example drosophila melanogaster.

I would say that the AM is both an algorithmic model and a physical model, and that it embodies (or instantiates) a mathematical theory of the cosmos. (In fact, it seems to have instantiated two theories: the Greek and the Babylonian cosmologies.)

Great, but let's note that 'they embodied (or instantiated) a mathematical theory of the cosmos' in a highly constrained and specific framework of motion.
