Math and Physics are probably the last strongholds of male domination. But female mathematicians are coming.

If you look at the senior facuilty member of Harvard Math department, there is only two female professors (out of 26 listed there). But if you look at the junior facuilty members, there are 5 female professors out 18. So from the pipeline point of view, it is just a matter of time. Granted that most of junior faculty members may not make it at Harvard, they will go somewhere else and become a full profressor.
