Pi Day is perhaps the world’s most prominent math nerd holiday. Held each year on March 14 (3/14), Pi Day is meant to celebrate the mathematical constant known as Pi, the ratio of a circle’s circumference to its diameter, and more specifically the first three digits of 3.14159.
Pi Day was first established in 1988 by Larry Shaw, a mathematician based at the Exploratorium in San Francisco, and each year it’s been celebrated at elementary schools, universities, and other places where math enthusiasts gather.
In Philly, there are a bunch of celebrations and commemorations to choose from this week for 2017’s Pi Day. (Keep an eye out for cancellations due to the impending snowstorm.)
The Independence Seaport Museum (211 S. Columbus Blvd.) will mark Pi Day with a Build a Robotic Boat event at 11 am on March 21 (it was postponed because of the weather forecast). Along with Snapology, the museum will help participants use Lego models and learn about building boats and even computer programming.
The Free Library of Philadelphia’s Culinary Literacy Center (1901 Vine St.) will celebrate Pi Day with some actual pies, courtesy of chef Valerie Erwin. This “magical, mathematical adventure” will tie in the with the 15th anniversary of One Book, One Philadelphia.
In another event under the auspices of One Book, One Philadelphia, a talk and tour of Bok (1901 S. 9th St.), will feature beer, wine and pie, in honor of Pi Day.
NextFab (2025 Washington Ave.), the South Philly co-working space, will host a discussion— with samples— on 3/14 called “Pi Day: The Science of Baking.”
Whole Foods has announced special deals on pies to celebrate Pi Day. Large bakery pies and take-and-make pizzas will be $3.14 off on Tuesday only.
Andpizza (1430 Walnut St.), the Center City location of the Washington-based pizza chain, will host Vegas-style weddings at its location throughout Pi Day — pizza included. Click here to sign up to get married.
One more for after the kids go to bed: Tattooed Mom (530 South St.) will host a Pi Day Pie Toss, featuring QC Malt specials. The event will benefit the Sunday Love Project, a local charity for the homeless.
