Who says you can't be beautiful and smart at the same time....

Math geeks know about Erdös numbers: Paul Erdös is defined as having an Erdös number of 0, and every one else is defined as having an Erdös number one greater than the minimum Erdös number of anyone they have co-written a published mathematical paper with. (My Erdös number is infinte; Hank Aaron's is joked to be 1, since both he and Erdös signed the same baseball).

Many folks know about Bacon numbers: Kevin Bacon is defined as having a Bacon number of 0, and everyone else is defined as having a Bacon number one greater than the minimum Bacon number of anyone they have acted with in a movie. Typically playing "self" doesn't count, nor being crew, an extra, or documentary footage.

As you can figure, very few people have Erdös-Bacon numbers, which is the sum of a person's Erdös and Bacon numbers. Someone would have to be both proficient in mathematics to have a co-authored published mathematical paper and proficient in acting enough to have appeared as an actor in the movies. By these strict criteria, Wikipedia lists only 8 people, 3 of which are women.

And, if I may say so, fairly hot women as well -- Danica McKellar, Natalie Portman (not the best picture of her... to ribby for my tastes), and Kiralee Hayashi.

Why aren't more sexy mathematicians involved in the movie biz?

(BTW, Kiralee and Danica's Erdös-Bacon number, 6, is the same as Richard Feynman, who has exactly one acting role, playing "The Physicist" in a very obscure and strange movie called "Anti-Clock" from 1979.).
