Happy Pi Day. Here are some very interesting facts about Pi. There is a ton of information on the Internet related to its importance in math, in tradition, in beliefs, in culture, and more…

From the official Pi Day site:

*Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) 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 the infinite digits of Pi, talk to their friends about math, and to eat Pie.*

*Pi has been calculated to over one 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.*
