Erdos-Bacon Number

Did you know that there exists something called "Erdős–Bacon number "? according to Wikipedia it is "the sum of one's Erdős number -which measures the 'collaborative distance' in authoring mathematical papers between that individual and Hungarian mathematician Paul Erdos—and one's Bacon number -which represents the number of links, through roles in films, by which the individual is separated from actor Kevin Bacon." seems like Erdos was one of the most prolific sceintists in mathematics and Bacon is considered as one of the most prolific actors, and these numbers are basic measures of "small world phenomenon". Among people with defined Erdos-Bacon Number you can find Erdos himself (with Erdos-Bacon number of 3) , Stephen Hawking (with Erdos-Bacon Number of 7) and Natalie Portman(with Erdos-Bacon Number of 7)!!
