In German science, we have a special problem. We lose talented women at the time they get pregnant. Some of it occurs because they are encouraged - by their husbands, bosses and the government - to take long maternity leaves.

In mathematics and science, there is no difference in the intelligence of men and women. The difference in genes between men and women is simply the Y chromosome, which has nothing to do with intelligence.
