Local and global connectivity – a tale of two datasets

The original images were generated based on facebook friendship data as well as data on scientific collaborations from Elsevier’s Scopus. The map of scientific collaborations was in itself inspired by the facebook map – I considered a direct comparison to be interesting. Note that – as far as we know – most brain regions (particularly in early sensory areas) exhibit a connectivity pattern that is quite similar: Mostly local connectivity with some long range connections. In this sense, the external social network seems to replicate the internal one.

Comparing scientific collaborations and facebook connections

Above: Scientific collaborations. Below: Facebook friendships

The image speaks for itself. Neither is a strict subset of the other, with interesting systematic differences. The scientific one basically seems to be a mapping between “global cities“.

And they say that there is no such thing as a social scientist…

Update: Flight paths seem to exhibit similar patterns as well.
