It's Pi Day!

It's here again! Pie Day. Or ... pi day! Pi - that mathematical ratio of a circle’s circumference to its diameter.

Today millions of people worldwide, from elementary school children to retired scholars, will celebrate both a mathematical constant and a sweet filling in a wheaten crust. In other words — Pi Day.

Pi is the ratio used to compute the circumference, area, and volume of circles.

For those who didn’t memorize it in middle school, that works out to 3.141592653, which is why we celebrate it on 3/14!

We at Rainier Yurts are especially fond of pi day, because like the popularity of yurts, Pi Day is celebrated world wide. Also like yurts - Pi is round!

Below is an amazing edible work of art that my 12 year old nephew, Charlie, made to celebrate Pi Day.

Some interesting facts:

Tech and science companies love Pi Day. In Massachusetts, Raytheon Company employees will deliver apple pies to middle and high school math teachers within 3.14 miles of company offices in Arizona, California, Florida, Maryland, Massachusetts and Virginia.

The Google Doodle (the art that sometimes graces the search engine’s search box) typically honors Pi Day with a clever graphic representation of how it works.

Pi is interesting in part because it’s an irrational number. That means it continues indefinitely, without repetition or pattern. Which makes memorizing it a fun challenge.

Thus far pi has been calculated out to more than two trillion digits, but of course its length is infinite.

That’s how Mr. Spock in Star Trek managed to stop an evil entity that has taken over the Enterprise’s computer system. He ordered it to “compute to the last digit the value of pi.”

Pi Day gets extra credit because it’s also Albert Einstein’s birthday. The German theoretical physicist was born on March 14, 1879.

National Pi Day is actually a U.S. holiday. The House of Representatives passed House Resolution 224 in 2009, designating March 14 as National Pi Day. The resolution “encourages schools and educators to observe the day with appropriate activities that teach students about Pi and engage them about the study of mathematics.”

Next year’s Pi Day will be even more exciting. On that day, math geeks will get one, shining moment in which they can write the date as: 3/14/15; 9:26:53. Which, everyone knows, are the first ten digits of pi in perfect order. I will have to place my order with Charlie early! As I am sure he will be busy baking pies for all of those who celebrate this fun and wacky day.

Enjoy your journey - wherever it may lead you!
