What is Pi Day?

Happy Pi Day! On March 14th (3/14), math nerds all over the world will be celebrating one of the most famous irrational numbers (sorry tau)! I believe this year’s Pi Day is very special because the date (at least the American date) is 3/14/15 which represents the first five digits of pi. Even better this year the date and time, 3/14/15 9:26:53 am, will represent the first ten digits of Pi (3.141592653)! The greek letter π represents pi and it was first used by William Jones in 1706. Its value is usually rounded out to 3.14 for everyday calculations. If I were to write every single digit of pi it would probably take me years upon years to write out. Currently pi clocks in to be about 10 trillion digits!

So what’s so special about the number pi? Well it’s the ratio of a circle’s circumference to its diameter. No matter what the size of a circle may be, this ratio will always remain the same. It will always be equal to about 3.14 or pi! When it comes to measuring the area or volume of geometric shapes, like circles or cylinders, pi makes this calculation much easier!
