In waiting for my combinatorial explosion of a factorial design experiment to complete, I decided to find out what my Erdos Number looks like, which is basically defined as the collaborative distance between yourself and the famous mathematician, Paul Erdos. Turns out, I have an Erdos number of 4 via the following chain of co-authorship.

/me -- Anja Feldmann -- Edward G. Coffman, Jr -- Joel H. Spencer -- Paul Erdős.

You can calculate your Erdos number here.
