Remember how awesome it was that the top three finishers at the Google Science Fair were all girls? They got some well-deserved attention for that.

Here’s a story that probably won’t get as much press, but it’s just as impressive considering how few women go into mathematics.

At the 2011 International Mathematical Olympiad, 18-year-old **Lisa Sauermann** not only obtained a perfect score — giving her sole possession of first place — her gold medal performance put her atop the IMO Hall of Fame.

In other words, she’s the best problem solver in the more-than-50-year history of the competition. And she’s a *she*.

In case you’re curious, these are three of the six problems she had to solve in this year’s tournament…

(Please don’t ask me to explain them…)

Speaking of women in math, you’ve all seen **Vi Hart**‘s latest video, right? Excellent.
