For math mavens around the world, it’s time to celebrate the next major holiday – Pi Day. The first Pi Day was celebrated in 1988 at the San Francisco Exploratorium, and takes place every year on March 14th (3.14, get it?) and has come to honor all things math, as it coincides with Albert Einstein’s birthday. One of the largest celebrations of Pi kicks off March 8th at Einstein’s former stomping grounds, Princeton, and focuses on the more fun aspects of all things Pi in the world around us.
We’ve pulled together resources to help you celebrate Pi Day with your family (Although you should also feel free to celebrate it by calculating the area of your favorite pie, using pi, before slicing it up to share with your loved ones. Mmm. Pie.).
Pi Day Apps
What would Pi Day be without an app or two to test your knowledge of the infinitely long number? There’s several free and recent apps available for iOS and Android phones, here’s just a few.
iOS App: Learn Pi Free

What’s a better way to spend the day than at the theater watching Oscar winning film Life with Pi? The story is actually about a boy named Pi who finds himself stranded on a lifeboat with a ferocious Bengal tiger, not about the number, but it is a fantastic film worth seeing.

Cooking Up Pi
While not a techie gadget, it certainly qualifies as geeky. You can get your very own Pi Symbol Ice Cube Tray to impress your friends. According to the description, it evidently is also good for “casting other materials, such as meatloaf”
