Friday is Pi Day

Anyone who remembers middle school geometry knows at least a little bit about Pi, the ratio that allows us to compute the circumference, area, and volume of round things. March 14, or 3/14, is recognized by math geeks as Pi day. That happens every year.

The New York Times is featuring a pi puzzle this week in the blog Numberplay. It was recently discovered that pi can be computed to any number of digits using two colliding balls. This discovery will be explained in the form of

In 2013, the Kickstarter-funded project to build a “Pie Pan for the Geeky Cook” raised 877% of their goal and successfully launched this fun Pi-shaped Pie-baking product. Go buy it from Amazon now, you know you want it.

Pi Day (3/14) is the unofficial holiday dedicated to pi. Pi is the ratio of a circle's circumference to its diameter, and it's an irrational number, so it can't be expressed as a simple fraction of two integers. The number starts out with
