“America again wins the annual International Math Olympiad! The contest pits the brightest high-school students of countries against each other in six-member teams. The American victories continue the mastery by the European cultures that invented most of modern math. This supports the claim (I hope I do not sound racist) that European superiority is genetic. In any event, the outcome is crucial because these young prodigies will shape the future of their peoples for many decades”.
