Happy Square Root Day

Today is Square Root Day. Square Root Day is a rare day that occurs when the day and month are both the square root of the last two digits of the year as in, √9=3, or 3²=9, or 3×3=9. Square Root Days only happen nine times a century. The last one was February 2, 2004, and the next is April 4, 2016.

I hear you are suppose to celebrate by eating root vegetables cut into squares.

There is another geeky math holiday coming next Saturday. March 14th is a math holiday that happens every year. It’s Pi day, 3-14 or 3.14.

Then for even more math geekiness I ran across this awesomely funny t-shirt. I want it.
