The Pi-iest Pi Day of All Pi Days!

I don’t know about you, but I love Pi Day. When I was in high school, we always celebrated with pie in math class, so it was basically the best thing ever. Math class and Pie? All at once? Why, yes, I think I’ll buy that.

Pi Day after high school was always slightly less cool. But I’m a math nerd, so it always has nerdy appeal. But this is the best one yet. See, celebrating at 3:09 on March 14th was fun, but this year, celebrating at 9:26 makes me so happy in such a nerdy way. I even almost bought this shirt to celebrate.

Now, some fun factoids about Pi.

  • As it is irrational, it is a looooong number. So long in fact that it is used as a stress test for computers.
  • It is also a very old concept, with the first evidence of its calculation and use in Ancient Egyptian and Babylonian times. Their original calculations were extremely close (within 1% of true value). It has been calculated with increasing degrees of accuracy ever since. Computers took over calculating it in the mid 1900s, first with handheld calculators and eventually with modern computers. Since then it has been computed to over a trillion digits!
  • The Greek letter we all know as the symbol for pi is actually a relatively recently development in Pi’s long history, being first used by the mathematician William Jones in 1706.

My favorite and last Pi factoid is that Albert Einstein was born on a Pi Day! Not a perfect Pi Day like this one, but still, Pi Day, and that is what I call cool. Now, go indulge in the time honored tradition of stuffing pie in your lovely faces. I know I will.
