First of all, let’s refresh. What is pi?
Pi is a constant value used in math that represents the ratio of a circle’s circumference to its diameter, which is 3.14… and so on, to over one trillion digits beyond a decimal point.
When is Pi Day?
Pi Day is celebrated on March 14th, to honor the numerical digits of pi.
The fact that the 14th of March also happens to be Albert Einstein’s birthday delights mathematicians. It’s the icing on the cake — or dare I say, pie?
History of Pi Day
In 1988, physicist Larry Shaw linked March 14 with the first three digits of pi and organized a special day to bond the staff at the San Fransisco Exploratorium by offering fruit pies and tea to everyone starting at 1:59 p.m., the following three digits of the value.
Celebrating the occasion became an annual tradition at the Exploratorium, with 2022 marking its 35th year. You can experience their Pi Day Celebration by joining for free online via Facebook or YouTube March 14th between 12:00 – 1:30 p.m.
Congress declared Pi Day a national holiday in 2009. Since then, celebrating pi has become pop culture phenomenon, most notably by indulging in pie.
Bring on the pie!
My husband and I love that we share our anniversary with Pi Day. Neither of us are mathematicians, but we enjoy that on our special day we can satisfy our sweet tooth with our best-loved dessert, pie!
And my personal favorite is the Pioneer Woman’s Flat Apple Pie. It’s a fun spin on the American classic. I love its rustic look, and the fact that there is no need for perfection.
Any day that combines fun, education, and pie is a day worth celebrating in my book!
