For those who love math, we all know what Pi Day is. We aren’t talking about food here, we are talking about the infamous, never-ending number, 3.14.
You may wonder what Pi is. Pi is the ratio of the circumference of a circle to its diameter. It's not equal to the ratio of any two whole numbers.
The use of Pi has been dated back to the early Greeks approximately 4,000 years ago. According to CNN.com, Pi Day started 28 years ago at San Francisco's Exploratorium. Physicist Larry Shaw, who worked in the electronics group at the museum, started celebrating pi on March 14, 1988, primarily with museum staffers. The tradition has grown to embrace math enthusiasts from all walks of life.
The true “randomness” of pi’s digits has never been proven, but March 14 also happens to be Albert Einstein's birthday.
