Today is Pi Day, and if you don’t know what that means, hit up an old math textbook.
Pi is the number expressing the ratio of a circle’s circumference to its diameter. It’s used in engineering, science and statistics and begins with 3.14 and goes on into infinity.
Hence, March 14, is international Pi day.
If math isn't your thing, celebrate the day at these local restaurants and bakeries putting their best “Pi” forward.
