Farey Tree Anon, I studied that Plimpton 322 article. Hilarious that all this probably started as a project cost analysis for some engineer or business manager ~6000 years ago. Like "Shit guys we gotta figure out the dimensions of this ramp some we know how much limestone to order from the quarry for this 1000 cubit length ramp. Go figure this shit out, we're on the King's payroll anyways, and we don't want too many slaves dying hauling extra rock from the quarry if we're gonna make our deadlines. Tell that fucking nerdy kid who sits around thinking all day to figure it out. He's a fucking weirdo, oh well, he's great at drawing triangles all day."
Thus was born the First Autist, lol.
