# Happy Pi Day!

Today is Pi Day, due to the date description being of 3.14, which is the most commonly known form of Pi.

Pi is a number that is considered a mathematical constant and was originally used to calculate the ratio of a circle’s circumference to it diameter. The number is has been since been used in various mathematical and physics formulas. Because the number is named “Pi”, it is often represented by a Greek letter and is often referred to as “Archemede’s Constant”. The Pi number is a mathematical constant with a never-ending decimal representation that never repeats itself. Many people enjoy showing their prowess by how many numbers AFTER the decimal they can recite.

These days, Pi Day is celebrated as a day to enjoy just that: Pie! Since the use of the Pi constant is in relation to a circular constant, a pie is the perfect way to represent this. So have yourself a slice! And just to demonstrate the number for those who are not familiar with it, this is the longest form of Pi after the decimal I was able to find (without searching too deeply):
