It’s Pi Day! Time to Celebrate!

Happy Pi Day!

Here’s just a little history of this special day…

It was due to physicist Larry Shaw in 1988, that March 14 will forever be now known as Pi Day.  This is the day that has been set aside to celebrate the mathematical sign – Pi.  The date, 3/14 (which also represents the first three digits of pi) also happens to be Albert Einstein’s birthday.  (How’s that for a coincidence? 🙂 )

The first Pi Day was in San Francisco at an interactive science museum called the Exploratorium.  However, it wasn’t until 2009, when legislation was passed by the US House of Representatives, that it became an official National Holiday.

It was in Ancient Greece that a mathematician by the name of Archimedes became the first to accurately calculate the value of pi.  However, due to the fact that it is an irrational number (it continues on into infinity), we have determined that only the first three digits (3.14 or 22/7) are enough to create accurate estimations in problem solving.

The word ‘Pi” was derived from the first letter of the greek word ‘perimetros’; meaning circumference, i.e. it’s the constant ratio of a circle’s circumference to its diameter.

Since the mid-18th century pi has been represented by the Greek letter π.

And there you have it… the history of Pi
