Knowing the International Pi Day

Today is the Pi Day and while many of you would think of some delicious baked goods, it isn’t about celebrating that Pi, but rather, a day for celebrating the mathematical constant pi.

A dedicated site is also present to celebrate the Pi Day – According to information available on the website, 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.

Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant, which is approximately 3.14159. Pi is also the ratio of the circumference of a circle to its diameter.

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.

Here are some fun facts about Pi:

  • It is not possible to truly measure the circumference or the area of a circle because it is not possible to truly know the value of pi. Pi is an irrational number, meaning its digits go on forever in a seemingly random sequence.
  • 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).
  • In 2002, a Japanese scientist found 1.24 trillion digits of pi using a powerful computer called the Hitachi SR 8000, breaking all previous records.
  • The first million decimal places of pi consist of 99,959 zeros, 99,758 1s, 100,026 2s, 100,229 3s, 100,230 4s, 100,359 5s, 99,548 6s, 99,800 7s, 99,985 8s, and 100,106 9s.
  • “Pi Day” is celebrated on March 14 (which was chosen because it resembles 3.14). The official celebration begins at 1:59 p.m., to make an appropriate 3.14159 when combined with the date. Albert Einstein was born on Pi Day (3/14/1879) in Ulm Wurttemberg, Germany.
  • The Guinness Book of World Records states that Lu Chao holds the world record for memorizing the most number of digits of pi. He memorized 67,890 digits, which took him 24 hours and 4 minutes.

While you’re celebrating, you can say Happy Birthday to Albert Einstein or take a minute to remember renowned physicist, Stephen Hawking, who passed away earlier today.
