Updated for 2015: This year’s is an especially wonderful Pi Day as we will hit 3/14/15 at 9:26:53—the first 10 digits of Pi!
I first learned about Pi Day when my daughter was in Middle School. I wondered where this day had been my whole life. Best celebrated at 1:59 p.m. on March 14 to match the first few digits of the number Pi (and the extent of most people’s memorization, 3.14159), with a pie, of course — savory or dessert version.
Math moment: What is Pi anyway? Ahem — Pi is the number expressing the ratio of a circle’s circumference to its diameter. It’s used in engineering, science and statistics and begins with 3.14 and goes on into infinity. It’s also captured a lot of people’s imaginations. The record for Longest Pi Recitation belongs to belongs to Japan’s Hiroyuki Goto, who memorized 42,195 digits. How is that even possible?? A teen holds the North American record.
I’ve gathered a few pies to help you celebrate. It seems like a more fun way to mark the day than memorizing digits. But, to each his or her own!
This is my own recipe for Classic Apple Pie. You could add a Pi symbol in crust (or cut out a Pi symbol) to the top of this, or any, pie.
When I think of Pie Mavens, I think of my friend Leah Brooks and her stunning and sometimes unexpected fruit pies, like apple with thyme or double lemon blueberry, or her chocolate cream, pumpkin, lattice-topped cherry, or perfect pecan pies!
Enjoy your Pi Day!
