The Erdős–Bacon number is a (ridiculous) measure of the small world phenomenon (SWP). It combines the two primary SWP measures of academia and cinema. The former calculates the collaborative distance from Hungarian mathematician Paul Erdős, while the latter considers the distance from Kevin Bacon in terms of roles in movies.
I have an Erdős–Bacon number of 9.
My Erdős number is 4
1. Tagliamonte and Denis (2008) LOL! For Real
2. Sankoff, Tagliamonte, and Smith (2006) Goldvarb X
3. Chvatal and Sankoff (1975) Longest common subsequences of two random sequences
4. Chvatal and Erdős (1972) A note on Hamiltonian circuits
My Bacon number is 5
1. I was in Possum Box with Doug Marks
2. Doug Marks was in Retribution with Daniel Morrison
3. Daniel Morrison was in Degrassi with Kevin Smith
4. Kevin Smith was in Scream 3 with Neve Campbell
5. Neve Campbell was in Wild Things with Kevin Bacon
4 + 5 = 9
What a glorious waste of time!
