Confidence is one of the sexiest things in guys and girls.

I know we can't always know what medical surprises may happen during childbirth. But my hope is to go fully natural - no epidural, no interventions. Wish me luck.

When you know that you can overcome challenges, you do gain that self-respect, and then you won't end up in a situation that you regret later on.

A lot of girls think they have to choose between being the smart geeky type or the beautiful bimbo.

I've done a little directing, but I love acting more.

I feel blessed to be having a really easy pregnancy.

My main concern with the condition of mathematics in high school is that there's a lot of fear involved! Math is not, generally speaking, presented in a fun way. The concepts, as I see them, are fun, and that's the way I'd like to convey them myself.

Let's make math fun and sexy and glamorous. Smart is sexy, that's one of my main messages.

When girls are asking themselves 'Who am I?' for the first time and they hear all this bad PR about math, they think, 'Well, whoever I am, I'm not somebody who likes math.'

If I had caused any trouble worth mentioning, you would have read about it in 'Star' magazine, which is probably why I didn't cause any trouble worth mentioning.

Most of the time I liked school and got good grades. In junior high, though, I hit a stumbling block with math - I used to come home and cry because of how frustrated I was! But after a few good teachers and a lot of perseverance, I ended up loving math and even choosing it as a major when I got to college.

Math has a lot of negative stereotypes, but it can actually be fun and incredibly empowering.

A reciprocal of a fraction is found by flipping it upside down. If you want the reciprocal of a mixed number or a whole number, just convert it to an improper fraction, and then flip it!

My husband is a composer, so he plays piano all the time and I sit there and clap telling my unborn child, 'Hear me clap, hear the music.' I know music, in general, is supposed to be good for babies to hear.

There's nothing unclassy about being naked, if it's appropriate.

When I was 15, I had a crush on this guy who was really good at magic, and so I learned to juggle, thinking it would impress him. I spent hours and hours practicing, planning to show him. And then I never even saw him again. But at least I learned how to juggle.

I want girls to feel the confidence you get from being smart. They get so many messages that tell them the most important thing is to be beautiful.

There's no reason to stereotype yourself. Doing math is like going to the gym - it's a workout for your brain and it makes you smarter.

When you do a lot of acting your entire life, you see the entire set from one point of view. To have a chance to step back and pull it all together is really exciting. You want to do it all; you want to have a hand in everything.

I noticed there were so many people, especially women, who would come up to me having recognized me from TV and say, 'I heard you were a math person, why math? Oh my gosh, I could never do math!' I could just see their self-esteem crumbling; I thought that was silly, so I wanted to make math more friendly and accessible.

The fun little proofs that you can do with algebra - they are sort of like crowd pleasers in a way. Like, the .9 repeating equaling one. It doesn't take a lot of algebra to prove that, and it's really fun. It kind of wows people. It's like they're watching magic happen right before their eyes.

I've been eating tons of organic foods, staying away from processed sugars, white flours, and anything artificial. It's the same as my normal regime, but I'm being even stricter, because everything I put into my body is literally building this precious baby inside me.

Girls think that being glamorous means making mistakes and being irresponsible. And that's just not true. The smarter you are, the better prepared you are to make decisions in your life, the more likely you are to lead a satisfying life and be glamorous and fun and anything you want to be.

Students never think it can be the teacher's fault and so I thought I was stupid. I was frustrated and would come home and cry because I couldn't do it. Then we got a new teacher who made math accessible. That made all the difference and I learned that it's how you present it that makes it scary or friendly.

When you do take the home pregnancy test, it doesn't quite seem real. But when you see the baby and the heartbeat on the ultrasound, it's so incredible.

I was born in San Diego, and we moved to Los Angeles when I was seven. A couple of years later, I started acting!

I took a break from acting for four years to get a degree in mathematics at UCLA, and during that time I had the rare opportunity to actually do research as an undergraduate. And myself and two other people co-authored a new theorem: Percolation and Gibbs States Multiplicity for Ferromagnetic Ashkin-Teller Models on Two Dimensions, or Z2.

It delights me that I don't fit the stereotype of an actress.

So somebody told me that if I wasn't a coffee drinker yet, by the end of college I'd have to be, because a math major is so tough I would have to stay up very late. I was going to need coffee to do that. Well, merely because they said that, I never drank coffee in college, never got addicted to it, never needed it.

People talk about 'getting rid of the old image', and I guess there's some merit in that. But the truth is that people loved 'The Wonder Years' - I can't turn my back on it.

I played Winnie Cooper on 'The Wonder Years' from ages 12-18, and did a few other movies during some of the summers.
