Happy Pi Day!


Can pi be fun? Of course it can! Remember pi is the ratio of the circumference of a circle to its diameter. It is an irrational number which means it cannot be written as a fraction but it can be written as a non-repeating decimal. But for ease of calculation we’ve all used it in math class as 3.14 (and today is March 14, get it?).

As if that isn’t fun enough, here are some more fun pi facts:

  • The ancient Babylonians knew about pi 4,000 years ago. They calculated it as 3.125
  • There is an invented language/dialect called “Pilish” in which the numbers of letters in successive words match the digits of pi. There is actually a book written entirely in Pilish by Mike Keith called Not a Wake.
  • The record for most pi digits memorized belongs to Lu Chao of China. Set in 2005, he managed to recite 67,890 digits.
  • Pi has been calculated to 22,459,157,718,361 digits.
  • If you hold a mirror up to 3.14, it spells PIE!

Shepherds pie

And that last one is more reason to have pie on pi day! Bookman and I celebrated with a shepherd’s pie. He used a casserole dish so it isn’t exactly round, but the intent is there! The potatoes on top got a little extra brown but it all tasted delicious. Inside was lentils, garlic, onion, peas, corn, mushrooms and spinach. Lots of leftovers so we get to have it again. And again. And probably again.

Did you know that January 23rd and December 1st are National Pie Day? But wait! There is also a National Blueberry Pie Day (April 28), a National Strawberry-Rhubarb Pie Day (June 9), National Strawberry Pie Day (September 28), and National Boston Cream Pie Day (October 23) — overlooking the fact that Boston Cream Pie is actually a cake but it is still round so it counts. Kind of.

So. Much. Pi(e).
