Apocalypse |

Title text: I wonder if I still have time to go shoot a short film with Kevin Bacon. |

## Explanation

According to Wikipedia, Paul Erdős (26 March 1913 – 20 September 1996) was a Hungarian mathematician who published more papers than any other mathematician in history, working with hundreds of collaborators.

An in-joke developed among mathematicians called the Erdős number (similar to a Bacon number for film actors, which we'll discuss in a minute). By definition, Erdős has an Erdős number of 0. Everyone who has co-written a mathematical paper with Erdős has an Erdős number of 1. Everyone who collaborated with them (but not Erdős himself) is assigned an Erdős number of 2. In general, if *k* is the minimal Erdős number of all the people you've written papers with, your Erdős number is *k* + 1. The Erdős number is the length of the shortest "chain" from you to Erdős.

Not everyone has an Erdős number, meaning that they don't have any chain linking them to Erdős. Most non-mathematicians do not have an Erdős number.

In this comic, the apocalypse happens. Cueball quickly writes a math paper and gets everyone from the math dept. to sign it. Then he gets the resurrected Erdős to sign it. This way everyone from the math dept. has an Erdős number of 1.

Paul Erdős described people who had stopped doing mathematics as "dead."

The title text mentions a similar (and less esoteric) meme called "Six degrees of Kevin Bacon", or simply Bacon numbers. This time, the chain's center is actor Kevin Bacon, and the links are formed by two people appearing in the same movie. Unlike Erdős, Kevin Bacon is not dead, so those of you wishing to get a Bacon number of 1 still have a chance.

# Discussion

Imagine the result if the ressurected Erdős also appears in that proposed short film with Bacon. They'd both immediately get Erdős–Bacon numbers of 1, for themselves, and then every traditionally Erdős-numbered person *and* every single Bacon-numbered person would be guaranteed to end up with an Erdős–Bacon number of no more than their existing (Erdős|Bacon) number plus one! It would make a mockery of the entire system!!! ...and *that's* why the end of the world is a Bad Thing^{TM} 178.105.100.250 18:42, 23 May 2013 (UTC)

- (Because there are pedants out there, I wish to immediately acknowledge the intrinsic error in such a statement... Anyone who hasn't acted XOR hasn't co-authored a paper can't get a finite Bacon||Erdős number to add to their finite Erdős||Bacon number, and someone who co-authored a paper with someone who acted with a second Baconised person cannot count that particular link as part of either chain, unless otherwise qualified, and therefore would count for both... Although the intermediary person might get a chance to connect to both if the original guy gets Erdős-connected by a different route. But way to ruin my own joke.)
- ((Oh, and my Bacon number is no more than 3, by way of an uncredited film appearance alongside Ian McKellan. I haven't checked to see if anyone else that's relevent has less than his presumed value of 2, but I'm not Erdőlised at all yet. Maybe that's my next goal in life. I know someone with an E-number of <=3, but obviously that's not enough to be
*worthy*of geting an EB# of 7 or less for myself. 178.105.100.250 19:15, 23 May 2013 (UTC) ))

Without the title text it could be seen as a reference to Erdös' signature. Erdős used to sign things pgom (poor great old man) then ld (living dead) then ad (archaeological discovery) then ld again (legally dead) then cd (counts dead) so it could be them trying to see if he'd sign living dead.
