# Brian Cox, EBS #13

Sean from Timeblimp floated the possibility of rock star/particle physicist Brian Cox having a well-defined Erdős-Bacon-Sabbath number, but to my knowledge nobody has actually worked out what it is. So here goes.

It’s easy to find Brian Cox’s Bacon and Sabbath numbers (they’re both three) but his Erdős number is somewhat harder. I managed to find a path of length seven using only papers with three coauthors or fewer, but Cox has worked in gigantic collaborations like ATLAS. It may be possible to get a shorter path through one of the papers he shares with thousands of coauthors.
