mikejuk writes "Which cities around the world produce not just the most but the best scientific papers? Using a database and Google Maps the answer is obvious. A paper at Physics arXiv describes how two researchers combined citation data with Google maps to create a plot showing how important cities around the world were in terms of their contribution to physics, chemistry or psychology."

Physics: http://www.leydesdorff.net/topcity/figure1.htm Chemistry: http://www.leydesdorff.net/topcity/figure2.htm Psychology: http://www.leydesdorff.net/topcity/figure1.htm And for the record, the authors refer to these as "fields of study", not "fields of science."
