I remember hearing that part of that is that one fancy thing even poorer families often had at the time was a nice clock, and generally the third estate wasn't interested in buying a whole new one

For general context-free grammars, at least if you count ambiguities for each tree (which I'm fairly certain JSON's grammar doesn't have), you can do it as a bunch of interleaved recursions, though converting that to a single polynomial is difficult in general

That's not a problem, since what I was trying to say is in fact that you can reduce every recursion in JSON's grammar not involving element into Kleene stars, so element is complex regex of element, and that's the fixed point

If you use a form of BNF with regular expressions, you can inline everything into <element>, crunch that big regular expression into its rational generating function, and get a fixed point formula for the JSON one

I don't want to get into the weeds but I do think that people talking about this stuff with NC specifically should learn about the Moral Mondays protests, why and how they happened, and the name and title of the person who started them.

I think you're confused about who you're talking about, because it sounds like you might be describing pre-state hunter-gatherers which was a very different thing from medieval peasantry

Knowing things like "where the word «serf» comes from" and "when the Northern United States industrialized" I'm pretty sure it wouldn't be hard to turn this sort of statistic into Confederate apologia

Ironically that actually definitely falls under the enumerated rights of the copyright holder, but then gets its own carveout as educational uses are one of the big things that get you pushed towards it being fair use

I don't know about the pairing but the Frobenius is basically just x mapsto x^p over a field where p=0; it turns out that this also preserves addition and the integers mod p (Fermat's little theorem)

I think the role of straight-up luck shouldn't be discounted either.

I think I recall seeing that preserving supersymmetry requires that parallel transport preserve a spinor, and I know that in 6 real dimensions that's equivalent to the monodromy group being SU(3) in SO(6) which can be shown equivalent to the Calabi-Yau condition
