Today is 3.14.2015. Today we celebrate the discovery of Pi. In 1706, mathematician William Jones realized that the decimal 3.141592 … never ends and that it cannot be expressed precisely. “The exact proportion between the diameter and the circumference can never be expressed in numbers,” he wrote.
That was why he felt that it needed its own symbol to represent it. It is thought that he chose π either because it is the first letter of the word for periphery (περιφέρεια) or because it is the first letter of the word for perimeter (περίμετρος). ENJOY A SLICE OF PI TODAY! -#ShadHistoryHit
