I know I live a charmed, beautiful life and nobody wants to hear a celebrity whine. The last thing I want to do is complain; I love what I do and I know every job comes with a downside.

My mom has always said that the one thing she wishes she had done differently is have a job. She felt like the single-mindedness made her a little nuts sometimes, and she could have used an outlet for herself when we were little.

I think that it's not as crazily different, my job, from anyone else's, as people let themselves believe. I think people get wrapped up in their own idea of what it is, but it's really not that.

I don't understand how women can manage to get back in shape with a new baby and a job.

I want my girls to love math. I want them to think that being a scientist is the coolest possible job on the planet. I want them to not be afraid to lean toward their femininity.
