Friday, March 14, 2025, (3/14) is Pi Day. Pi is the ratio of a circle’s circumference to its diameter. The number starts with 3.14, but it goes on for infinity.
I can consistently remember just 3 digits of Pi, which obviously is nothing to brag about.
However, my friend, art director and designer Lyndsay Cooper, is famous in certain circles for memorizing Pi. Many years ago, at a party, with no warning, I asked her to recite Pi for me and she recited the first 50 digits. And that’s only because she was unprepared. In high school she was champion of a Pi memorizing contest and memorized many more. Video below.
Pi Day Trivia: Did you know that Albert Einstein was born on Pi Day in 1879? At that time, there weren’t as many Pi Day pizza deals, but it’s still a fun fact.
