# Nerd Alert: Happy Pi Day!

Pi, being a phenomenon in the mathematical world, is a mathematical constant that is the ratio of a circle’s circumference to its diameter. Sounds simple enough, doesn’t it? Well, it isn’t simple at all. It is an irrational number, which means it cannot be expressed exactly as a ratio with two integers. Fractions such as 22/7 can only be used to approximate Pi and is only accurate to two decimal places.

In fact, it is still to this day incalculable. Even the fastest super computers in the world haven’t been able to find the end to this mysterious number. It has been calculated to over 10 trillion digits. That is expected when patterns are present within the calculation, but Pi has no pattern whatsoever; it is completely random.

Pi is and has been for centuries used as a cult-like symbol in various organizations. There are Pi memorization competitions and other “Pi Games” that are popular in the super-geek community. The current record holder for memorizing 67,890 digits of Pi is Lu, Chao from China. The top five people in the world to memorize digits of Pi are all from Asia, the next 4 in line are from Europe, and the 10th is from the good ol’ U.S. of A.

Pi Day itself began in 1988 when Larry Shaw, the “Prince of Pi”, decided March 14th was the perfect day to celebrate this infinite number. It also happens to be the birthday of the great Albert Einstein. Coincidence?
