March 14 – Celebrate Pi Day!

Pi Day is an annual celebration commemorating the mathematical constant π (the Greek letter pi), the symbol for the ratio of the circumference of a circle to its diameter. Pi Day is celebrated around the world on March 14th since Pi = 3.1415926535…

Next year will be especially exciting: in the year 2015, Pi Day will have special significance at 9:26:53 a.m. and p.m., with the date and time representing the first 10 digits of pi.

While the American Pie Council (APC) denotes January 23 as National PIE Day, the U.S. Congress recognizes March 14 as PI Day, but both can be celebrated by baking pies.

According to the APC, the first pies were probably made by early Romans, and appeared in England as early as the Twelfth Century. Pie came to America with the first English settlers. The early colonists cooked their pies in long narrow pans calling them “coffins” like the crust was called in England. Among the other benefits of the American Revolution, it brought into common use the word “crust” rather than “coffin.”

How to celebrate? Make your pie big enough to share! “Hand pies” may not be appropriate, as shown by this calculation by Trader Joe’s:

On the other hand, this “pi pie,” created at Delft University of Technology in 2008 suggests a more share-friendly approach to Pi Day!

  1. I am reminded of the one scene in the movie Life of Pi, where the young Piscene Patel writes out [from memory] on the blackboard in school the 50-mile long sequence of “pi”.

  2. I would bake a pie to celebrate but no one around here would eat it. :/ Happy Pi Day to you!

  3. Happy Pi Day! I may just bake this afternoon…

  4. All these pie pics all over the web today and here we are, gluten free.

  5. Happy pi day! We made both apple and cherry hand pies at my house last night with which to celebrate today. Yum!

  6. We’re not baking pie today but maybe apple turnovers count just a little? :-)

  7. No pi(e) here — we have girl scout cookies. *Someone* bought them because he couldn’t resist.

  8. Oh, well I can see how calling the crust a coffin might ruin one’s appetite!

  9. Hurrah for Pi Day! I did not celebrate it with pie at all, but I did eat delicious Indian food and go to see Veronica Mars with a bunch of my friends. So that was as good as pie. Better actually. I don’t truly care that much about pie.
