Thanks, that's a good datapoint. Auroral physics is not something that we're taught here in the U.S., even in honors high school physics classes. Perhaps physics' appeal is always framed in the human experience. In the case of high latitude living, the science describing the auroral physics is a curiosity that can help drive research in plasma physics. Sweden is a powerhouse of plasma physics and spaceweather forecasting capabilities, in fact. I work with a guy who lived in Kiruna, and he told me that it hurt to breathe the outside air for 5/8ths of the year. That was a no-go for any prospect of going over there. Also, the love of my life has a Swedish surname, appears Swedish in many ways, and is somewhere between 25-50% Swedish, genetically.
