The University of Virginia computes the Bacon Number for any actor, similar to the Erdos number in mathematics. We trace the acting links of Shahrukh Khan, Amitabh Bachchan, and even Prabhu Deva to Kevin Bacon. (BCG did the same for consultants who have worked together, and it turns out that I have a Bruce Henderson number of 3.)
Bacon Number
I trace connections between Bollywood stars and Kevin Bacon using the Oracle of Bacon. Similar to the Erdos number, this concept applies to consulting; I found I have a Bruce Henderson number of 3.
