Mathematicians rejoice, this is your day, 
-day is here. We hope you aren’t irrationally excited but 3.14 only rolls around once a year.
From the American Mathematical Society:
The holiday honors a special number: “Pi,” which is pronounced just like “pie”. Pi is an infinite, non-repeating decimal, so it’s usually abbreviated to 3.14, hence we celebrate it on March 14! Mathematics represents pi with this symbol: .
What does the number mean? For every circle, its distance around (circumference) is always a little more than three times its widest distance across (diameter). When you divide the circumference by the diameter, you get this fascinating number that has no end: 3.1415926535897932384… Indeed, computers have calculated pi to 105 trillion places (and counting) and have found no repeating sequences. As the ratio of a circle’s circumference to its diameter, is irrational and transcendental—qualities sure to bring a twinkle to any mathematician’s eyes.
