You asserted that Russia should produce more mathematicians because it is large. But large mainly empty land area will not have that effect.
I see that you have some kind of problem with what's been said about the production of great mathematical minds in Russia, so why don't you offer something contrary to the assertions made so far? Rhetorical gaming is really not an effective tool to make your point.
shockingly few when you consider how large the country their working with is
I replied that the country isn't actually that large in terms of people, so your point is invalid. Now you seem to be saying that empty land should produce more mathematicians.
Also, it's "they're".
