**Why Pi matters**

Today the Pi day is a once in a life time occurrence.

"Every March 14th, mathematicians like me are prodded out of our burrows like Punxsutawney Phil on Groundhog Day, blinking and bewildered by all the fuss. Yes, it’s Pi Day again. And not just any Pi Day. They’re calling this the Pi Day of the century: 3.14.15. Pi to five digits. A once-in-a-lifetime thing.

I’m dreading it. No hope of solving any equations that day, what with the pie-eating contests, the bickering over the merits of pi versus tau (pi times two), and the throwdowns over who can recite more digits of pi. Just stay off the streets at 9:26:53, when the time will approximate pi to ten places: 3.141592653."

The beauty of pi, in part, is that it puts infinity within reach. Credit Photograph by Jeffrey Coolidge / Getty
