QUOTE : Years ago, when I was working on my master's thesis, I went to New York for a semester as an exchange student. What struck me most was the sky. On that side of the world, so far away from the North Pole, the sky is flat and gray, a one-dimensional universe. Here, the sky is arched, and there's almost no pollution. In spring and fall the sky is dark blue or violet, and sunsets last for hours. The sun turns into a dim orange ball that transforms clouds into silver-rimmed red and violet towers. In winter, twenty-four hours a day, uncountable stars outline the vaulted ceiling of the great cathedral we live in. Finnish skies are the reason I believe in God.
