And this brings to mind the Thanksgiving pies, all 6 or 7 or whatever it was, and how we taught my 8 y.o. nephew about pi using pie. We actually told him he couldn't eat pie until he knew about pi--he didn't seem to take this threat all that seriously, but still quickly memorized the definition, and 7 to 10 digits of the number. And we measured (sloppily) the circumference and diameter of several circular objects (including a pie), did the calculation and arrived at something in the vicinity of 3. He found this procedure disappointing when it didn't come out closer to 3.14159.
Ah, it appears it was only 5 pies at Thanksgiving, if you don't count the tartlets we made to use up the extra chess pie filling. The 4 in this picture, plus a black bottom that was still in the fridge. And the memory goes faster every year--what did we make? Deep dish apple, buttermilk chess, the dark chocolate thingy that wasn't as good as I'd hoped, and ____. Something else chocolate, perhaps? Maybe chocolate chess.
