Let's Celebrate Pi Day!


Is your brand planning to celebrate Pi Day today? Pi is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. Pi Day is an annual opportunity for math enthusiasts to recite as many recalled digits of Pi, talk to their friends about math, and, of course, also eat pie and/or pizza pie.

According to Wikipedia, "Pi Day is observed on March 14 (the 3rd month) since 3, 1, and 4 are the first three significant figures of the mathematical symbol Pi. It was founded in 1988 by Larry Shaw, a staff physicist at the Exploratorium, a science museum in San Francisco."

According to PiDay.org, "Pi has been calculated to over 50 trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits."

Which brands can, and should, celebrate today?

Frozen pie brands Marie Callender's, Sara Lee, and Mrs. Smith's would benefit from the extra publicity.

And then, there are fast-food/delivery, restaurant, and frozen pizza brands such as Domino's Pizza, Pizza Hut, Papa John's, Little Caesars, Blaze Pizza, California Pizza Kitchen, Lou Malnati's, DiGiorno, Red Baron, and Newman's Own.

Since today is a great day for these brands to showcase clever marketing, who will stand out?

Some things that happened on March 14 in history:

In 1927, the American Society of Civil Engineers elected Elsie Eaves as an associate member. She was the first woman elected to the society.

In 1879, Albert Einstein was born in Germany. In 1921, he won the Nobel Prize for Physics.

In 1997, gymnast Simone Biles was born. Her 11 Olympic medals and 30 World Championship medals make her the most decorated gymnast in history and one of the greatest female athletes of all time.
