ScienceBlogs

Every year, scientists and mathematicians geek out on Pi Day, March 14, in celebration of the universally important ratio of a circle's circumference to its diameter.

ScienceBlogs is full of scientists and mathematicians, so of course we had to get in on the celebration. Last year, we threw the first annual Pi Day Pie Bake-Off, challenging our bloggers to make the most delicious-sounding pie they could and post the recipe (and pictures! the most important part) to their blog. After putting all the pies to a vote, one clear winner emerged: Spicy Pi Bacon Squared. Honorable mention went to ScienceBlogger Janet Stemwedel, who baked a total of eight delicious sounding pies for the contest with her sprogs.

The winning pie. Think you can top this? Let's see you try.

In 2010, the Pi Day Pie Bake-Off returns, but this year the rules are different, the prizes are bigger, and we are excited to have a co-sponsor for the contest: food website and staff favorite, Serious Eats, whose past coverage of pies has been impressive.

This year, the contest is open to both readers and bloggers. We will post all the submissions on our editorial blog, Page 3.14, and put them to a final vote at the conclusion of the contest on March 14. The Grand Prize Winner will receive a prize of $314 in cold, hard cash. Three winners in the following categories will each receive a "Simple as 3.141592" T-shirt generously donated by mental_floss: Judges' Pick, Most Photogenic, and Best Concept Pie. The last must be somehow representative of a concept in science or math—your choice.

To enter the 2010 Pi Day Bake-Off, first upload a photo of your pie to Photograzing on Serious Eats. Then, email your pie submission to pi@scienceblogs.com. Please include your name, blog or website if you want us to link to it, and the link to the photo on Photograzing. We will email you to remind you when your pie has gone up for the vote, so you can pester your friends to vote for you. The Bake-Off is now closed for submissions. Please try again next year.

*Voting is now open for the Grand Prize winner of the 2010 Pi Day Pie Bake-Off on Serious Eats. See the ten finalists on Page 3.14, or all of the mouth-watering entries below. Vote before midnight on Thursday for your favorite pie.*

Let the piesta begin!
