Pi Day

On March 14, 1988, Larry Shaw, a physicist at the San Francisco Exploratorium, coordinated a circular march and pie eating extravaganza. Chosen for its resemblance to the first three digits of Pi, 3/14 has since become international Pi Day, and a reason for math and sweets themed parties around the world. Pi (3.1415926…) is the mathematical constant of a circle’s circumference divided by its diameter, which is essential to many formulas in mathematics and physics. Here at GreenVest, we use it often – for example, to get the diameter of a tree or pipe by measuring its circumference.

March 14th also happens to be Albert Einstein’s birthday. He is a big name in math and physics, most famously for his Theory of Relativity, and though we’re not sure about his pie consumption it seems fitting for Pi Day to also be his birthday.

Celebrating Einstein and Pi is a day for coming together, reciting the digits of pi, and paying special attention to the circles we overlook every day. At GreenVest, our Annual Pi Day Celebrations normally involve sharing lots of pizza and pies together in our office. This year, due to social distancing and a Sunday celebration, everyone extended these traditions to their family and friends. In short, our usual celebration looked a bit different this year, but nevertheless pies were had by all.

Enjoy these pictures of our distanced celebrations, united by a love of round foods and the mathematically proven joy they can bring. A big thank you to Laura Kelm, one of our Project Managers, for coordinating this fun and delicious celebration. We look forward to continuing this pie-filled tradition in 2022, but until then: how many digits of Pi do you know?
