Title Clue

The trivia game Six Degrees of Kevin Bacon is based on the concept of the small world phenomenon and rests on the assumption that any actor can be linked through his or her film roles to actor Kevin Bacon

Every Actor has a Bacon Number!

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.
