Greg, I know you don't mean harm here, but physics consists of predominantly above average, highly intelligent males. A female face isn't an honest reflection of the field in general, so that leads me to believe that such an advertisement is meant to invite social opportunists on board or to scare potential members away? Highly intelligent females that love science seem to be quite welcome and come on their own, but they have to try to earn their places the exact same ways as the others do before they receive it. Attempting to recruit females just because they are female and not because they love science doesn't make it a healthier place for anybody, it isn't fair for highly intelligent young men to see unfair opportunities being given, and it isn't fair for those few highly intelligent young women to have to deal with the consequences.
