EDITED to emphasize that the idea Kontsevich "took from string theorists" is not as big a deal as title of TFA implies, thanks sno129
On page6 is the crucial^W main idea that Kontsevich took from string theory, the Hodge Diamond
It's memorable, at least :)
En.wiki has a quick explanation
Mirror symmetry translates the dimension number of the (p, q)-th differential form h^(p,q) for the original manifold into h^(n-p,q) of that for the counter pair manifold.

Don't miss the caption from the end of the previous page, what the sum means :)
