Mathematical! It's the Pi Day Collection

The Guinness World Record for the most memorized digits of pi is held by Rajveer Meena, for memorizing 70,000 decimal places of the mathematic concept. The Guinness World Record for the world'€™s largest pie is 20 feet across and weighs 3,699 pounds. The highest anyone in the DBH staff can count to Pi is only seven digits. And National Pi Day, March 14, was declared a holiday in 2009 by the U.S. House of Representatives.

And for Pi Day 2016, Design by Humans has you covered, with our National Pi Day Collection! Some of our favorites are below, and you can shop the entire collection for all your pi needs here.
