Physicist Dirk Brockman used data on dollar bill movements to identify economic regions.
While the physical transfer of cash may no longer represent our economic activity as well as it once did, it is still interesting stuff. I do quibble with the concept that the economic activity regions correspond to “states” (Brockman is German). I also think information on direction of flow is extremely important. I am happy to see that the concept of “The Carolinas” is apparently real and that Ohio State fans express their dislike of Michigan with their wallets too.

As a prelude to ScienceOnline 2013, Scott Huler showed a lucky few what he had learned about the Raleigh storm water sewer system while researching his book on the infrastructure of modern cities, On the Grid.
You can see all my photos from the tour (well all the ones that turned out OKish) at my Flickr page. Continue reading
