The Social Graph of a Famous Mathematician

Above is the social graph [a.k.a. social network map] of Paul Erdõs. He was an expert in the mathematics of networks. Erdõs practiced what he preached — he was a weaver of social networks and thus a builder of social capital.

Erdõs was known for traveling the world and collaborating with mathematicians on problems and proofs he found interesting. Many scientific papers resulted from these intense face-to-face collaborations. Erdõs had 507 co-authors, some of whom collaborated with each other. Erdõs’s partnerships exposed the social structure of scientific discovery. An excellent mathematical analysis — Evolution of the social network of scientific collaborations[PDF] — is available from Laszlo Barabasi and colleagues.
