I learned something new today

Apparently, Danica McKellar - famous for playing Winnie Cooper on The Wonder Years (and some other stuff including a recurring character on The West Wing) is some sort of mathematical genius.

She was recruited to UCLA by a mathematics professor who had her working on proving a theorem during her undergrad studies. The theorem is now known as the Chayes-McKellar-Winn Theorem and is explained in her article: Percolation and Gibbs states multiplicity for ferromagnetic Ashkin–Teller models on Z²

I'm not sure what that means from the title...but I'm determined to find out.

Slightly less intimidating - Danica answers fan math questions on her website.
