Was pi invented or discovered?

[Angrboda]

I'd have to go with false dichotomy. At least in my understanding of the terms. It wasn't discovered in the sense that it exists independently of us such that it can be "found". Nor was it invented, in the sense of being caused to come into being by an agent. I wrote on the subject once before, but looking at what I wrote, I didn't do a very clear job of explaining it, so I'm not going to refer to that prior explanation.

Maybe I'll come back to it later.
