This week Wolfram and math enthusiasts around the world are honoring an unusually significant Pi Day. Taking place on 3/14/15, at 9:26:53 am and pm the date and time will represent the first 10 digits of ? in a once-in-a-century event.

This year, why not add to your Pi Day celebrations by participating in our Pi Day Tweet a Program Challenge? We’re looking for your coolest Pi related code, like neat visuals of operations on radii or anything else that shows off your Pi savvy. Check out the examples below if you need some inspiration:

Compute the area of a sphere: Integrate[r^2Sin[th], {phi, 0, 2Pi}, {th, 0, Pi}] The result involves Pi and it is equal to the area of four circles: https://twitter.com/wolframtap/status/570173450842730496

Find palindromes in pi: "here's a large palindrome-like pattern very early in pi 3.141592653589 (79) 32] {38} (46264)3{38} [32 If only it weren't for that pesky extra 3.?"

To win, send your submissions to @wolframtap from now through next Tuesday, March 16. Then, as with our other challenges, we’ll use the Wolfram Language to randomly select winning tweets (along with a few of our favorites) to pin, retweet, and share with our followers. If you win, we’ll send you a free Wolfram T-shirt! No hashtag is required for entry, however, we do encourage you to share your code with your friends by retweeting your results with hashtag #PiDay.

Also, we’re at SXSW in Austin, TX this week; if you’re able to attend make sure to stop by for our special Pi Day event. And regardless of where you are, don't forget to watch the Wolfram blog this week for more exciting Pi Day news and developments!
