Sorry to resurrect a thread, but today on BBC Radio4's "Woman's Hour" programme, Marcus de Sautoy, the new Simonyi Professor for the public understanding of science, succeeding Dawkins, was talking about women in maths. You can hear him at:

The most surprising thing for me was that a country like Spain, that I would have stereotyped as machsimo ridden, has an almost equal number of female and male maths professors! Surely that's good evidence for a lack of sexual difference?
