re: why women end up in science courses:
I am a computer scientist who ended up majoring in maths and computing at uni.
I think that kids become interested in certain subjects when they are
very young, round about 5 years of age. There's a saying about "give me a child
until the age of 7 and I'll have him for life" - has anyone seen the British
"35 up" series?
I think your parents attitude to school is very important, my parents both
came from a small European village where education was a privilege and I
always thought school was a lot of fun, and important and got great
encouragement from my parents, particularly in maths.
I was an only child and I went to an all girls state school until I was 15,
(free) - we were never told that we couldn't do something that a male could do.
