Pi Day is an annual celebration commemorating the mathematical constant π (pi). It is observed on March 14 since 3, 1, and 4 are the first three digits of π.
The earliest known official celebration of Pi Day was organized by Larry Shaw in 1988. This celebration was held at the San Francisco Exploratorium. The Exploratorium continues to hold Pi Day celebrations.
On March 12, 2009, the U.S. House of Representatives passed a resolution recognizing March 14 as National Pi Day. For some, the entire month of March is recognized as "Pi Month".
What is Pi?
Pi (π) is the mathematical constant that has been known for almost 4000 years. Its value is the ratio of any circle’s circumference to its diameter in Euclidean space or the ratio of a circle’s area to the square of its radius. The value of pi is approximately equal to 3.14159265, but it is an irrational number and its decimal representation never ends or repeats.
The lower case Greek letter π is used because it is the first letter of the Greek work περίμετρος (perimeter), which probably refers to its use in the formula perimeter divided by diameter equals the constant for all circles. The concept of π has become the most common ground between mathematicians and non-mathematicians.
So, with all of this information, let's celebrate!!
