### Is it because 3.14 also represents the day Albert Einstein was born? Let’s jump through a few facts why PI π is important to us:

The record for discovering the most number of digits of pi belongs to Fabrice Bellard.  He calculated 2.7 trillion decimal places on just a desktop computer.

The Greek letter Ï€ was selected to describe pi in 1706 by William Jones, an English mathematician.
It would take 12 billion digits of pi, typed in a normal-size font, to reach Kansas from New York City.

When people want to measure ripples emanating from a central point, they use pi.

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.

The number 1 is the most commonly occurring number in the first 100,000 decimal places of pi.  It occurs 10,137 times.

March 14 is known as Pi Day because of its date: 3/14.  It is also the birthday of Albert Einstein, who was born in 1879.

What we use PI for:

PI= the ratio of a circle’s circumference to its diameter.

It is used to process tv, radio and radar signals as well as calculating flight plans.

Astronomers use PI to assist in the search for exoplanets as well as measuring the distance between stars.

Calculating the first trillion digits of pi can be used as a stress test for computers.

PI is also used to predict weather patterns as well as syncing satellites for GPS navigation.
