And the dominance of Asians is interesting. It's a very cultural thing.
I can't remember who proposed it, but the idea that East Asian languages are much easier to learn basic counting is interesting.
The idea is that Chinese, Korean and Japanese all have easier languages for counting. This gives young Asian students a small, but real advantage when first learning math that accelerates as time goes on.
I would be interested to see how many of the top math Asian-American or Asian-Anglo students know one of those three languages or not.
If a lot of them have zero knowledge of Chinese, Japanese or Korean, then clearly this idea is dead.
