Copenhagen Quotes (6 quotes)

I admired Bohr very much. We had long talks together, long talks in which Bohr did practically all the talking.
Recalling his Sep 1926-Feb 1927 stay in Copenhagen.
In History of Twentieth Century Physics (1977), 109. In A. Pais, 'Playing With Equations, the Dirac Way'. Behram N. Kursunoglu (Ed.) and Eugene Paul Wigner (Ed.), Paul Adrien Maurice Dirac: Reminiscences about a Great Physicist (1990), 94.

If I were forced to sum up in one sentence what the Copenhagen interpretation says to me, it would be “Shut up and calculate!”
In column, 'Reference Frame: What’s Wrong with this Pillow', Physics Today (Apr 1989), 9. The Copenhagen interpretation refers to quantum mechanics. Mermin has since asked, 'Could Feynman Have Said This?', in Physics Today (May 2004), 10, if Richard Feynman may have used the “Shut up and calculate” retort first, since there were numerous examples giving that attribution on the web. To date (6 Jun 2015), no response supporting Feynman as a source has ever been received by Mermin. This was confirmed in an email to the Webmaster, which stated, “Nobody ever sent me any evidence that Feynman had said it. I’ve concluded that he didn’t, but it’s hard to prove a negative.” The reasonable conclusion is that this would almost certainly be a misattribution by the so-called Matthew effect to a more-famous person. Even seen attributed to Paul Dirac! In a Physics Forum web post (28 May 2014) The Austrian remembers being taught by a QM lecturer who liked using the quote, but added: “there is not much else to do in QM anyway.”

In a sense [for the Copenhagen Interpretation], the observer picks what happens. One of the unsolved questions is whether the observer’s mind or will somehow determines the choice, or whether it is simply a case of sticking in a thumb and pulling out a plum at random.

You can talk about people like Buddha, Jesus, Moses, Confucius, but the thing that convinced me that such people existed were the conversations with Bohr.
About his time working with Niels Bohr in Copenhagen.
Quoted in Dennis Overbye, 'John A. Wheeler, Physicist Who Coined the Term Black Hole, Is Dead at 96', New York Times (14 Apr 2008).

You must come to Copenhagen to work with us. We like people who can actually perform thought experiments!
Said to Otto Frisch. Quoted in Otto R. Frisch, What Little I Remember (1979), 76.

[Niels Bohr] is a national pride to his fellow Danes. In Denmark, Bohr’s standing is only slightly less than that of the royal family and Hans Christian Anderson. When the wife of an American physicist casually told a gentleman seated next to her on a Copenhagen streetcar that her husband was studying under Professor Bohr, the old man jumped to his feet, swept off his hat with a flourish and bowed deeply.
Quoted in Bill Becker, 'Pioneer of the Atom', New York Times Sunday Magazine (20 Oct 1957), 52.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
