Science: the poster
We often hear about the unity of the sciences, but it's nice to see it.
Information Esthetics is giving away free posters. You just pay the shipping. And it's cheaper to order several at once (I'm talkin' to you, Berkeleyites).
This map was constructed by sorting roughly 800,000 published papers into 776 different scientific paradigms (shown as pale circular nodes) based on how often the papers were cited together by authors of other papers. Links (curved black lines) were made between the paradigms that shared papers, then treated as rubber bands, holding similar paradigms nearer one another when a physical simulation forced every paradigm to repel every other; thus the layout derives directly from the data. Larger paradigms have more papers; node proximity and darker links indicate how many papers are shared between two paradigms. Flowing labels list common words unique to each paradigm, large labels general areas of scientific inquiry.
Somebody put this on a t-shirt, stat!
IMMEDIATE UPDATE: no t-shirt (yet), but if you like this there is a lot more at this page, where the guy who came up with this explains why and how. In particular, there is a big comparative diagram that compares the science strengths of ten nations (US, UK, Germany, Japan, China, etc.). Very cool stuff.
