Did you know that the approximation for π is 3.14? That’s why Pi Day is observed on the 14th day of the 3rd month of the year – March 14th. The first Pi Day was celebrated in 1988 and is still observed by fans of math, science and physics around the world. While this mathematical value was not called π until the 18th century, ancient civilizations were aware of this distinctive number. The Babylonians used the fraction 25/8 (about 3.125), the Egyptians used 256/81 (about 3.160), the Indians 339/108 (about 3.139) and the Chinese used the fraction 355/113 (about 3.1415). Now, the value of π calculated by computers has more than 22 trillion digits!
We hope that you have another well-rounded day today! Remember to think kind thoughts, use kind words, and do kind things. We Love You.
Π is an irrational number. It cannot be expressed as a simple fraction and the decimal form never ends or forms a repeating pattern. While the value of π has been calculated into the trillions of digits, many scientific calculations round off the value of π at about 15 digits or less.
In 2007, Mark Umile set the US record for reciting the most digits of π – 15,000 digits. Suresh Kumar, from India set the world record for reciting the most digits of π – 17,000 digits.
