Three U.S.-born scientists, Saul Perimutter, Brian Schmidt, and Adam Riess,won the Nobel Prize in physics for discovering that the universe is expanding at an accelerating pace. Their discovery raised the question: What is pushing the universe apart? This has been labeled "dark energy," but no one knows what it is.
A single individual won the Nobel Prize in Chemistry this year - a Israeli scientist named Dan Shechtman. He recognized a new crystalline chemical structure that seemed to violate the laws of nature. Schechtman discovered what are now called "quasicrystals" atoms arranged in patterns that seemed forbidden by nature. The discovery :fundamentally altered how chemists conceive of solid matter" the Royal Swedish Academy of Sciences said in awarding the prize.
The Nobel Prizes certainly seem to give the Swedes a lot of influence on science.
