Pi Day. Some facts

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

Pi Day was created in 1988 by physicist Larry Shaw. It’s since become an international day, celebrated around the world.
March 14 is also Albert Einstein’s birthday.

 

SOME FACTS

• Pi is the most recognized mathematical constant in the world. Scholars often consider Pi the most important and intriguing number in all of mathematic
•  Egyptologists and followers of mysticism have been fascinated for centuries by the fact that the Great Pyramid at Giza seems to approximate pi. The vertical height of the pyramid has the same relationship to the perimeter of its base as the radius of a circle has to its circumference.
• If the circumference of the earth were calculated using π rounded to only the ninth decimal place, an error of no more than one quarter of an inch in 25,000 miles would result.
•  The first 144 digits of pi add up to 666 (which many scholars say is “the mark of the Beast”). And 144 = (6+6) x (6+6)
•  A mysterious 2008 crop circle in Britain shows a coded image representing the first 10 digits of pi.
