International Incoherent Scatter Radar Workshop in Kangerlussuaq, wandering around town was the obvious choice. Copenhagen is an old and beautiful city, but on a warm and sunny Saturday during the holiday season it is also very full of people. While cruising around a park, I happened upon Hans Christian Ørsted. I knew he lived here, but hadn't thought of him for a long time. However, he is highly relevant to radar, since he discovered, in 1820, the direct relationship between electricity and magnetism. Later, in 1829, he founded a college, which today is called the Technical University of Denmark (DTU). At the university, at DTU Space, Ørsted's legacy is very much alive. The institute monitors the Earth's magnetic field with a series of ground stations in Greenland, Denmark and the South Atlantic.
