this is exactly what I wanted to criticise by my comment. I don't think these rankings are that important because they don't capture what the (original) article wanted to measure. There's only one stanford, which might be better than every other university out there. But there are a lot, often way smaller, universities out there that produce fantastic research. You have to add them together.
