Today is my daughter Courtney's 28th birthday. Two weeks ago I got to be in the room as she defended her dissertation, and in May she'll be graduating from Columbia University with a PhD in Mechanical Engineering. So as a mom of a scientist (pinch me!) I couldn't help but love Lessons in Chemistry, by Bonnie Garmus. I read it while we were on a family vacation in Hawaii last February and told Courtney and Lizzie, my daughter-in-law, and our three sons, it was a must read for women in science, women in general, and all the people who love them. Thankfully, we've come a long way since Elizabeth Zott had to defend herself with a pencil in 1952. Courtney's experience included mentors, men and women alike, supporting her research and guiding her path and believing in her ability to succeed. And in like manner, Courtney has always taken time to encourage, teach and be a friend to the students rising up behind her. She's creating a beautiful legacy. Happy Bi...
