I just wanted to encourage everyone to head over to Susan's blog and check out her post about the importance of motherhood. An excerpt:

Women are not specially suited for higher mathematics, though many are gifted in this area, myself included, so the need seemed contrived to me. But women are specially suited for another vocation: motherhood. As my professor told me of the great "need" for women in higher mathematics, I could not help but think, but we need mothers far more!
