Happy Pi Day - Apple Pi

Geeks and Greeks rejoice – March 14th is Pi Day (3.14) – a day to celebrate the mathematical constant that seems to find it’s way into all things geometric.  Pi is the relationship of a circle’s circumference to its diameter, and mathematicians the world over have spent careers studying its value.  Pi is both irrational and transcendental; meaning that no fraction, series, or other finite mathematical expression can express its value exactly.  Here are some interesting facts about Pi’s mathematical history:

  • Modern supercomputers have been able to calculate the quadrillionth bit of Pi, which happens to be 0. (Quadrillion is 1,000,000,000,000,000)
  • Pi has been studied so much in mathematics that it has three distinct ages of history, briefly summarized as Geometric, Calculus, and Modern Computers.
  • The world record for reciting digits of Pi is 100,000 digits.

If you’re so inclined, you can learn a bit more about Pi (the constant), rent a copy of Pi (the movie), read Life of Pi (the book), or even eat an Apple Pie (the food).
