In case you are not familiar with Pi Day, March 14 (3/14) is the day that math enthusiasts celebrate Pi, the Greek letter that is the symbol for the ratio of the circumference of a circle to its diameter. Pi is an irrational number meaning that the digits after the decimal point never end and never repeat. The most common approximation of Pi is 3.14 which is why March 14 is considered Pi Day.
Watch this great video of Pi in Dominos. It is 3 minutes and 14 seconds.
Feel free to share this, and eat some pie to celebrate!
By the way, it's also Albert Einstein's birthday. Another reason to celebrate.
