Vizualizing Science

Columbia University computer scientist W. Bradford Paley, along with colleagues Kevin Boyack and Dick Klavans, categorized 800,000 scientific papers into 776 areas of scientific study (shown as colored circular nodes) based on how often the papers were cited together by other papers. The bigger a node is, the more papers it contains. Heavily cited papers appear in more than one node. Black lines connect any nodes that contain the same papers; the darker a link is, the more papers the connected nodes have in common. These links create the structure of the map and tend to pull similar scientific disciplines closer to one another. Where are you on the map?
