almost certainly doing those things and more (especially lin alg and diffeq solutions, and who knows what equivalent mathematical representations). Why wouldn’t it? even stereotyped, there are subtle feedback variations you need to account for.

there is certainly math going on in the brain at various levels, both equivalent models and identical sorts of calculations, it’s not just fuzzy matching.

it has them, they are just covered.

“it’s not oversimplified, oversimplifies and strawmans” lol

yes fluoride diffuses into enamel and chemically and mechanically hardens it. this effect is strongly linked to better dental outcomes for children and adults. also, tons of places actually remove fluoride to the needed levels because it is naturally higher.
