Arthur is in fine form today. Maybe he's psyched about the upcoming banquet. (I am.) (Tried to braid my hair in the front on either side & tie the braids back behind my head, but the tying didn't work, and they're all shabby anyway, so I was going to comb 'em out, but then I stepped on something & cut my foot & had to hydrogen peroxide it & inspect for mini-shards, and then I was out of morning.) S'anyway, ALG tried to explain the stair-step limit problem I am bothered by, and then what this smoother circle in the title of this paper he was carrying around is about (it's got to do with noncommutative geometry), and then he answered another question that's been bugging me: what operation are those computers doing when they figure π (that's supposed to be pi---ymmv) to more and more decimal places? (He showed me one simple formula for π that was proven long before Newton;there are other formulas that converge faster, give you 5 digits with 5 iterations---or maybe not "iterations," but something like that.)
Then he told us the following joke.
There are 10 kinds of people in this world: those who understand binary, and those who don't.

Our exec ed is Irish, and he's taking us all out for luncheon this day.
