Does Instructables have the largest collection of nerdy Pi Day pie recipes on the internet? Show me a site that has more! I've gathered my favorites here, but this isn't even the lot of them!
March 14 (3.14) has certainly become a celebration of sweet and savory pies, but it is also day to revel in the beauty of math. So when the next Pi Day rolls around, definitely cut yourself a slice of delicious pie, but also familiarize yourself with the number: it's the ratio of a circle's circumference to its diameter.
And maybe, if you had one slice too many, you can take a 3.14 mile stroll through your neighborhood, keeping an eye out for more pi pies cooling on windowsills.
