Numb3rs Season 1 Episode 5

Don: Yeah. Hey, Charlie, let me ask you something. The math thing that the father was working on, is there anyway that could be worth money?
Charlie: Well, it is one of the millennium problems.
Terry: What's a millennium problem?
Charlie: Seven like, classic difficlut math problems. The Clay Institute of Mathematics offers 1,000,000 dollars for the solutions to each one of them.
Don: All right, well, that's motive. So, how would he collect the award?
Charlie: Well, first the solution has to be published in a refereed journal. Then it has to achieve general acceptance in the math community over the course of two years, and then an advisory committe is convened...
(Terry interupts him)
Terry: It's possible somebody knows he's workin' on it, but doesn't know how far off the award is.
Don: Right. Well, who else would know he was working on it?
Charlie: I would check with the math journals, you know, because maybe he contacted some of them.
Don: All right. Why don't you give me some of those names?
(Hands Charlie a pad of paper and a pen.)
Don: Here, actually--you write it.
