I don't understand people who travel purely gastronomically, who book a Michelin-starred restaurant three months in advance and suddenly find themselves in Copenhagen or Barcelona with a zeitgeist plate of snail porridge.

If Copenhagen were a person, that person would be generous, beautiful, elderly, but with a flair. A human being that has certain propensities for quarrelling, filled with imagination and with appetite for the new and with respect for the old - somebody who takes good care of things and of people.

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.

I like Copenhagen, just because my shows there have been really good for some reason. Not that I love the city itself, but every time I play there it feels amazing. Pretty nice people there.

Both [Quine and Feyerabend] want to revise a version of positivism. Quine started with the Vienna Circle, and Feyerabend with the Copenhagen school of quantum mechanics. Both the Circle and the school have been called children of Ernst Mach; if so, the philosophies of Feyerabend and Quine must be his grandchildren.

"The Copenhagen Interpretation is sometimes called "model agnosticism" and holds that any grid we use to organize our experience of the world is a model of the world and should not be confused with the world itself.

If Copenhagen were a person that person would be generous beautiful elderly but with a flair. A human being that has certain propensities for quarrelling filled with imagination and with appetite for the new and with respect for the old - somebody who takes good care of things and of people.

So the old Copenhagen interpretation needs to be generalized needs to be replaced by something that can be used for the whole universe and can be used also in cases where there is plenty of individuality and history.
