I have been connected with the Niels Bohr Institute since the completion of my university studies, first as a research fellow and, from 1956, as a professor of physics at the University of Copenhagen. After the death of my father in 1962, I followed him as director of the Institute until 1970.
My wife is from Copenhagen and her father has been a huge Liverpool supporter since the early 1960s.
Copenhagen has done a remarkable job creating streets that are focused on bicycles and pedestrians.
Paris. Toulouse. Malmo. Copenhagen. Brussels. Berlin. For most people, they are lovely cities where you might happily take a holiday. But for the world's Jews, they are something else, too. They are place names of hate.
If the movie had ended in Hollywood fashion, the Copenhagen climate conference in 2009 would have marked the culmination of the global fight to slow a changing climate.
At some point, they must do a 'Borgen' tour in Copenhagen. Like the 'Sex and the City' tour, but on bicycles.
Right before I graduated from the national theatre school, I got the part of Roxie Hart in 'Chicago' in Copenhagen. That led to me playing it here in London. I was 26 when I came over for that. It was the first thing I did as a professional, and it is still the experience of my life.
In Copenhagen, we all ride bicycles everywhere, partly because it is impossible to park a car, but also because you can cross the city in 20 minutes on a bike.
I adore Copenhagen, where I live, but I'm really drawn to New York.
In Copenhagen, there's a long-term commitment to creating a well-functioning pedestrian city where all forms of movement - pedestrian, bicycles, cars, public transportation - are accommodated with equal priority.
