Every Scientist has an Erdös Number
Scientists and mathematicians have been calculating their Erdös number for years. Paul Erdös was the Kevin Bacon of mathematicians, having published more than 1400 papers with numerous collaborators. Anyone who was a co-author with Erdös has an Erdös number of one. Their collaborators, in turn, have an Erdös number of two, and so on. The network of mathematicians is a small-world network.
