**This year, Pi Day falls on Saturday, March 14 (3.14….get it?!). We’ll be celebrating a day early, on Friday, March 13th. Stop by Warner Library and pick up a free mini Entenmann’s pie while our supplies last!**

*A little history about Pi….*

It dates all the way back to the ancient Babylonians, who calculated the area of a circle to be three times the square of its radius. This calculation came to be Pi=3. It wasn’t until the Greek mathematician Archimedes of Syracuse (287–212 BC) came along and determined that Pi fell in between 3 1/7 and 3 10/71. The use of π as Pi’s symbol became popular in the mid 1700s, around 1737, when Leonhard Euler popularized its use. For more information about the history of Pi, check out the following sites:
