How does biology explain the low numbers of women in computer science? Hint: it doesn't. from Terri Oda
Now I'm not a computer scientist, but engineering falls under the same stereotype: "I'm too girly for math, let's go shopping." Crap like this and this. And engineering, like CS, requires only moderate use of actual math... once you've got the degree you can basically get machines (but not your brother) to do it for you.
There is no gender/biological difference that makes all men good at math while making all women good at shopping (For me, shopping is a necessary evil since its frowned on to go to my nice engineering job with holes in my clothing).
I wish I could say things are different regarding women in STEM fields since the days when my mother got her Chemical Engineering degree, but they really aren't... women still overwhelmingly do not choose technical degrees. And that's weird and it sucks, and stereotypes that a) girls are bad at math or b) being pretty means you shouldn't have to do your own homework are NOT helping.
