Happy Pi Day!

Posted By on Thu, Mar 14, 2013 at 4:35 PM

Every year, around the world, Pi Day is celebrated on March 1. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant ⎯ the ratio of the circumference of a circle to its diameter ⎯ which is approximately 3.14. No matter how big or small the circle is, this ratio will stay the same.

Why is Pi such a big deal?

Although it may seem like just another number from high school geometry, Pi is extremely important to everyday life. For one thing, Pi is the most recognized mathematical constant in the world.

Scholars often consider Pi to be the most important and intriguing number in all of mathematics.
It’s useful in many different fields of study besides math, such sociology, biology, and astronomy. In fact, anything that is cyclical depends on Pi.


So while you sit back and enjoy the wonderful weather this Pi Day, just remember that if it weren’t for π, you couldn’t go biking, listen to the radio, watch TV, or use a cell phone.

From the wheels on your car to the orbit of distant stars in the cosmos are all put to paper using Pi. These practical applications help determine the size, shape, volume, area, and circumference of circles.

So, whether we’re putting satellites in geosynchronous orbit, to testing super computers, to helping make that perfect pumpkin pie, Pi is an extremely well rounded number.
