Erdos numbers are kind of fun. They are counted by the number of academic connectors which separate two people on the "family tree" of advisors, students and co-authors. Erdos was famous for his collaborations, which is why mathematicians like to calculate their own Erdos number.

Last time I checked (various sources, some of which aren't available now sadly), I have

  • a Dirac number of 7 (and as my students know, I met Dirac and his wife once as an undergrad)
  • an Erdos number of 6
  • a Feynman number of 5
  • a (Roald) Hoffman number of 5
  • a Pauling number of 3
  • a Bohr number of 4
  • a Schroedinger number of 4
  • a Lennard-Jones number of 4
  • a Sommerfeld number of 4
  • a G.N. Lewis number of 3 (and I once met Lewis' last graduate student, Michael Kasha - a CU alum)
  • and a Karplus number of 2

So if you have ever published a paper with me, you have an Erdos number of no greater than 7, and so forth. Of course, everyone who has ever worked for me also has made other connections since and so these numbers may have changed!
