Big Data is our generation’s civil rights issue, and we don’t know it  

What’s really driving so-called Big Data isn’t the volume of information. It turns out Big Data doesn’t have to be all that big.

Rather, it’s about a reconsideration of the fundamental economics of analyzing data.

Tomorrow is the 50th anniversary of Yuri Gagarin’s historic manned spaceflight. Here’s some little-known facts about that legendary feat …

Map of scientific collaboration between researchers

In the spirit of the well-circulated Facebook friendship map by Paul Butler, research analyst Olivier Beauchesne at Science-Metrix examines scientific collaboration around the world from 2005 to 2009:

I was very impressed by the friendship map made by Facebook intern, Paul Buffer [sp] and I realized that I had access to a similar dataset. Instead of a database of friendship data, I had access to a database of scientific collaboration.

From an extensive database of academic citations:

I extracted and aggregated scientific collaboration between cities all over the world. For example, if a UCLA researcher published a paper with a colleague at the University of Tokyo, this would create an instance of collaboration between Los Angeles and Tokyo.

After that, Beauchesne used a similar mapping scheme that Butler used, and behold the results above. The brighter the lines, the more collaborations between a pair of universities.

There doesn’t seem to be much going on in places outside of the United States and Europe, but I wonder if that’s because of a limited dataset or really because there’s little collaboration in those areas. I suspect the former. Still very cool though.
