‘What The Child does every March 14’

It’s been quite a while since she wowed the math classes at Stuyvesant High School with her ability to recite pi to more than 400 places. But The Child still keeps her pi oar in, so to speak, by reciting pi to one hundred places every March 14. Which is still no mean feat.

Concentration is key. She says she imagines pictures. Or something

See, March 14 is Pi Day, when math nerds celebrate the one and only true magic number: π. Pi is 3.14 — get it? March 14 — a mathematical constant, never-ending, the circumference-to-diameter ratio of a circle.

But, math nerd or no, it’s still fun to watch her do her Pi Thing. He she was, just this morning:

Yes, braggety-brag brag brag, The Child has a knack for Pi reciting. She was so good at it at Stuy that the math department suspended the competition while she was student there — and just had her go around to the math classes and demonstrate.

‘And other hilarious tales of math and memory’

Me, I’ve never been such a great shakes at memorizing stuff. I mean, I can rattle off a bit of verse. (My go-to poem: ‘Listen my children and you shall hear…of the midnight ride of Paul Revere’. Impressed?) And I am of the generation that was pressed to learn (by heart) the preamble to the Constitution (a practice I highly recommend to any and all presidential candidates). But. Memorizing pi? I’m not so sure I even knew what ‘pi’ meant when I was a kid.

Pi comes to mind because yesterday was March 14. Which is, in some circles, known as Pi Day. That’s because ‘pi’, the ratio of a circle’s circumference to its diameter (yes, I had to look that up), is commonly given as 3.14. And March 14 is commonly given as 3.14. Get it?

Anyway. Pi Day is sort of a Big Deal. And not just among the Pocket-Protector Set. Pi Day got amazing coverage, not only in The New Yorker, but on Facebook. Yesterday, in fact, it seemed that posts about Pi Day outnumbered those about Donald or Bernie or Hillary. (Um, well maybe I’m just mathematically wishfully thinking here.)

The other thing about ‘pi’, the thing that gets everyone all atingle — well, maybe not everyone — is that pi is infinite. Again, according to my handy online source, mathisfun.com (hmmm, if you have to say something is fun, then is it?), pi is equal to 3.14159265358979323846. And that’s just for starters. See, the digits go on forever, and without repeating. This is like catnip to Math Nerds. Every year on 3.14, they get all excited and try to outdo each other reciting pi to as many places as they can. Seriously. Contests are held. Records are broken. Egos are threatened! Continue reading
