Pictured is the Urania Sternwarte, a public astronomical observatory built in 1907 in the sleek Art Nouveau style (called “Jugendstil” in Switzerland.) It’s close to the world-renowned ETH, a technical college that has turned out 21 Nobel prize winners, including Albert Einstein and William Röntgen. Incidentally, when you go to have a broken bone checked out in Norway, it’s called “having a Röntgen” not “getting an x-ray.”
