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.

I tell students, 'If you are learning from YouTube I almost don't want to teach you because what you learn from YouTube it takes 10 times as long to unlearn.' They do an approximation of the centre of the note, an approximation of the interpretation, a cloned version.

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.
