Editing Uncertainty principle (section)

=== Ideal detached observer ===
Wolfgang Pauli called Einstein's fundamental objection to the uncertainty principle "the ideal of the detached observer" (phrase translated from the German):

{{Blockquote|"Like the moon has a definite position," Einstein said to me last winter, "whether or not we look at the moon, the same must also hold for the atomic objects, as there is no sharp distinction possible between these and macroscopic objects. Observation cannot ''create'' an element of reality like a position, there must be something contained in the complete description of physical reality which corresponds to the ''possibility'' of observing a position, already before the observation has been actually made." I hope, that I quoted Einstein correctly; it is always difficult to quote somebody out of memory with whom one does not agree. It is precisely this kind of postulate which I call the ideal of the detached observer.|Letter from Pauli to Niels Bohr, February 15, 1955<ref>{{cite book |last1=Enz |first1=Charles Paul |last2=von Meyenn |first2=Karl |title=Writings on Physics and Philosophy by Wolfgang Pauli |url=https://books.google.com/books?id=ueTd4g7pc5MC&pg=PA43 |publisher=Springer-Verlag |year=1994 |page=43 |translator=Robert Schlapp |isbn=3-540-56859-X |access-date=2018-02-10 |archive-date=2020-08-19 |archive-url=https://web.archive.org/web/20200819235529/https://books.google.com/books?id=ueTd4g7pc5MC&pg=PA43 |url-status=live }}</ref>}}
