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…

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