We are mathematicians. We are mothers. Edited by Emille Davie Lawrence, Rachelle DeCoste, and Amanda Ruiz, this blog is about how these two identities intersect (and sometimes collide) each and every day. While colored by individuality, the common thread is that both paths are demanding yet rewarding. The aim is to challenge the traditional ideas of success in mathematics by sharing how we have defined success for ourselves both personally and professionally. By sharing these stories, we can empower others to pursue their life choices unapologetically while building a community of math mamas. Contributions, comments and questions from parents and non-parents are encouraged and welcomed.
