Apple, cherry, cheese, pecan, key lime … you name it, and there’s probably a pie for it. Pies are yummy, so why not make a pie out of every flavor or flavor combination possible, right? This time, we’re not talking about delicious pies you can consume but rather the mathematical number 3.1415. What’s so special about this seemingly simple number, and why is there a national holiday dedicated to it? Well, first of all, it’s not that simple. Pi (∏) is a constant number that measures the ratio of the circumference of a circle to its diameter. In other words, it’s a very important number that is used in engineering, construction, and … well … making lots and lots of things! Physicist Larry Shaw thought it was such an important number that he decided that it needed to be celebrated. So on March 14th (3.14, get it?), 1988, Mr. Shaw hosted the first ever Pi Day at the Exploratorium in San Francisco. His hope was to raise awareness of pi and to grow interest in the fields of engineering and math. But how does one celebrate Pi Day? By conducting a circular parade and serving up a lot of pies of course! We don’t know about you, but we’ll be celebrating Pi Day on March 14th with a few slices of pie!
