A couple of days ago the latest MAA Focus magazine dropped through my letterbox. On the fourth page was a picture of the US girls team for the China Girls Mathematical Olympiad. Six out of eight were Asian. This kind of proportion seems to be common. Clearly this is not a reflection of the demographics, or a case of Asians being more talented at mathematics. So, what else is one left with? High achievement typically requires sustained effort, which is more likely to be given to something one holds in high regard. And young people typically inherit their parents' values. I remember, a few years ago, one young lady telling me that her mother pointed out that she was working in a bank, wasn't very good at maths, and didn't need it. Why is it that Asian parents can see and appreciate the value of maths but white ones can't?
