Pi, represented by the Greek character π (Pi - pronounced like "pie"), is an irrational number and mathematical constant originally defined as the ratio between a circle's circumference to it's diameter. The circumference is the distance around the entire circle. The diameter is the length of a line that runs through the center of a circle from one side to it's opposing side.
The equation, circumference/diameter, roughly equates to 3.14... (or 3.14159265358979323846...).
Pi is so important, it is even celebrated as a national holiday on March 14th (3/14).
Although mathematicians have yet to decipher a pattern for the infinite series of digits following the decimal in Pi, it is responsible for many patterns we see within nature.
