π Day is celebrated on March 14th each year (3.14 in case you didn’t get it)

To celebrate this amazing number here is a really fun video from Numberphile on what happened when he measured the circumferance and its diameter with the use of a big batch of actual pies. So, take a look and see if you can think of anything he could have done to make things more accurate.

It’s great to be a math nerd… Enjoy π Day!
