About PI Day


A data-thon to build an online knowledge-base for public issues.

See our poster


To put data back into public dialogue, to discuss issues without rhetoric, and to make essential data easily available to the public.


The Princeton University community. Specifically, those who want their research to reach a broader audience, want to strengthen their understanding of complex issues; are looking to meet others with similar social issue interests; want to log Campus Community Challenge hours; or are interested in contributing to a crowdsourced web-application.


Pi Day! Wednesday, March 14, 2012, 5:30-8:30pm


Friend Center, Convocation Room (Room 113)


Anything else?

Free pizza, pies, and beverages served!

Please bring your laptop computer or tablet!

During PI Day, teams of students will be challenged to define the essential dataset needed to understand an issue of their choice. They will enter this data into an online database for future users to access to draw their own conclusions about the issues, free of opinionated journalism and rhetoric.

For example, data already online will tell you, in plain language, that in 2002, the Iraq war was forecast to cost 60 billion dollars but by 2011 spending was over 800 billion. Or that in Pennsylvania, a fracking well may be drilled as close as 200 feet to a home without the owner's consent.

Come to share what you know and learn more about what you don't know on PI Day.

This event is brought to you by Princeton graduate students Lauren Padilla, Dan Swain, and Elena Krieger, with support from the Eugene Wong '55 Fund for Engineering and Policy and Princeton's Keller Center.
