This most perfect Pi Day: 3.14.15

Pi Day 2015, 3.14.15, entertainment, worldwide celebrations, humor, Pi to its millionth decimal point,

Pi Day is celebrated on 14 march (3.14) around the world for obvious numeric reasons. But today’s Pi celebration is extra special because the date corresponds to the first four digits after the decimal point. That won’t happen again for another century.

The number “π” [represented by the Greek letter since the mid-18th c.] is a mathematical constant. It’s the ratio of a circle’s circumference to its diameter. π is an irrational number – meaning it cannot be expressed exactly as a ratio of two integers. Its decimal representation goes on to infinity without repetition or pattern.

So in honor of this great Pi Day, while π is most often represented numerically as 3.14159, the above illustration shows what π looks like to its millionth decimal point. If you don’t believe me, download the PDF here.
