Abstract

In lieu of an abstract, here is the chapter's first paragraph: ONE OF THE MOST QUOTED PHRASES in current popular culture is "six degrees of separation." It expresses the idea that, on average, any human ^being is connected with any other human being by at most six acquaintances. While there is much debate as to whether this is literally true, it is an interesting thought-experiment, as well as the basis for many fun parlor games. One of these is entitled "Six Degrees of Kevin Bacon," in which film fans try to connect the aforementioned actor with any other movie star with as few links as possible.
