Danica wants girls to learn math!

Danica McKellar is an actress and  an internationally-recognized mathematician.

She is best known to TV viewers as Winnie Cooper on the classic ABC series, The Wonder Years. During the 2002-03 season, Danica had a  recurring role as Elsie Snuffin on NBC's The West Wing. She has also guest starred in a number of TV series, including Working (with former The Wonder Years co-star Fred Savage) and CBS' How I Met Your Mother.

Taking a break from acting for college, Danica graduated summa cum laude at UCLA with a degree in Mathematics, and co-authored a ground-breaking mathematical physics theorem which bears her name (The Chayes-McKellar-Winn Theorem). For this accomplishment, she has been honored in Britain's esteemed Journal of Physics and the New York Times, who called her a "math superstar."

On August 10th, 2007, ABC World News with Charles Gibson named Danica "Person of the Week" for her role as the author of the bestselling "Math Doesn't Suck: How to Survive Middle School Math Without Losing Your Mind or Breaking a Nail."
