Happy Pi Day!

Today is a very special holiday of sorts for math enthusiasts around the world - It's Pi Day!  Every year on March 14, we celebrate pi.  What a wonderful excuse to share some fun facts about everyone’s favorite mathematical constant!
So for those who don’t already know, what exactly is pi?  Pi is an irrational number whose digits continue to infinity – which is why we round it to its shorter version, 3.14.  It is the ratio of a circle's circumference to its diameter and represented by the Greek letter, π.  It is a staple in geometry (shapes, hooray!) and other mathematic disciplines. 

Ready for some fun facts? 
*Pi has been studied for roughly 4,000 years by many different civilizations.  In 1650 B.C., an Egyptian scribe approximated and recorded the value for pi.  Amazingly, his estimation was only off by ~1% compared to today’s value.  Pretty impressive!
*Albert Einstein shared his birthday with pi day!
*Although pi is an infinite number, many individuals have tried to calculate its full value.  The most recent records show that pi has been computed to 12.1 trillion digits!1  Imagine how long that must have taken!
How do you plan to celebrate Pi Day?
