Welcome math geeks! Today is March 14^{th}, otherwise known as Pi Day. The rest of you can follow along or look up the answers in the back of the book.

This year Pi Day is exceptionally special because not only is it March 14^{th} but this is also 2014. Which is also known as 3/14.

All around the world math geeks or celebrate all things pi. The traditional pie baking is cranking up this morning. Which will be followed by the traditional Pi Day breakfast of pie. If you get a chance swing by the Exploratorium Museum in San Francisco. They are holding an all-day celebration of all things Pi and admission is free. Come early, the building has limited capacity and admission is not guaranteed. No food or drink is allowed so sadly, you have to leave your pies at home.

Other Pi Day celebrations include group formations of pi, geometry parties, running of the 3.14 mile Pi marathon and the traditional hotdog toss. During which hot dogs are throw on to a floor marked with evenly spaced parallel lines.

Why? Because the proportion of hot dogs that cross the lines when they fall works out to be approximately 1 over Pi!

Traditionally pi Day celebrations end at 3:14 PM when celebrants form the Pi formation and recite pi from memory. One by one, people will drop out of the formation until person who has memorized the most digits is declared the winner.

Don’t forget to watch The Life of Pi.
