"A few words to the young women: When you combine a career with raising a family, the family responsibilities generally rest more heavily on you than on your husband, and you may need to proceed more slowly with your career than you would without a family. This may have its good side in that you can save up some interesting and important things to do after your children have left the nest. However, the responsibilities can often be so heavy as to frustrate a woman's career, and a lack of suitable child-care facilities is a major roadblock. To me it is no mystery why there are not more women in leadership positions in science. It has been mentioned that I am the first woman to receive the Howard Vollum Award, and of course I am very proud to be chosen. But when it is no longer considered unusual for a woman to be so honored or to achieve a position of leadership in public life, then we women will know that we have made it."
