Who knew that I was contributing to scientific knowledge?

In December of 2006 I found myself on a business trip in Southern California. We stayed at the Marriott on Coronado Island. When I paid for my breakfast I was given a one-dollar bill that had "Track This Bill at www.wheresgeorge.com" stamped in red ink on the edge. I went to the site and learned that Where's George "is a website that tracks the natural geographic circulation of American paper money." (wiki). Shortly after this encounter I began entering bills and so far have recorded 1,628 bills of varying denominations ($1 vs. $5, not Baptist vs. Presbyterian).

As I have pursued this hobby I have found myself questioned continuously. It is obvious that some think I am a little nuts to spend time stamping and entering bills into this website (as opposed to the other reasons they think I am nuts). Well, after a little over two years I can now tell those scoffers that I am in fact contributing to scientific research.

Channel 7 News in Chicago just did a story on how a physicist at Northwestern University is using the data from the "Where's George currency tracking project" to predict the movement of people, and therefore the Swine Flu, throughout the US. Basically, he is predicting that when currency moves between two cities you assume that people moved as well.
