### Happy Pi Day!

### Happy Pi Day!

It's March 14, also written as 3-14, better known as National Pi Day!

For those of you not mathematically inclined, like me, you may not know pi's significance. Pi is the ratio of a circle's circumference to its diameter. So, for any circle, dividing its circumference by its diameter will give you the exact same number: 3.14159…or pi. Pi is also an irrational number, which means that its value cannot be expressed exactly as a simple fraction. Pi is an irrational number, too, meaning the numbers after the decimal point go on infinitely. Some humans are able to memorize pi out to one hundred or more digits, but powerful supercomputers are used to calculate it out into the millions, billions, trillions, and now, even quadrillions of digits.

In racing, pi is handy to know when building racetracks so everyone will know the radius of a corner or any other mathematical equation well over my head.

But in more practical terms, Pi Day gives the rest of us who aren't mathematical scholars a chance to enjoy and celebrate our favorite pie! Whether it's pizza pie, apple pie, cherry pie, chocolate creme pie or any other other thousands of types of delicious pies out there, today's the day to enjoy!

Leave us a comment below on how many digits you've memorized pi or your favorite kind of pie. Or both!

Happy pi day!
