Keeping Women in Physics

In the United States women constitute a steadily increasing fraction of scientists in all fields, but progress in Physics is much slower than in other fields. Utilizing the best available talent, including women, is vital to our future prosperity and security. I discuss some of the myths and realities about why the numbers of women are low, and what steps can be taken to improve the situation. I will argue that we do not so much need to, as a colleague recently suggested to me, ``pull them by the hair'' to get women into Physics - rather, we need to avoid pushing them out.
