Editing Schrödinger's cat (section)

===Bohr's interpretation===
Analysis of the work of  [[Niels Bohr]], one of the main scientists associated with the Copenhagen interpretation, suggests he viewed the state of the cat before the box is opened as indeterminate. The superposition itself had no physical meaning to Bohr: Schrödinger's cat would be either dead or alive long before the box is opened but the cat and box form a inseparable combination.<ref name="Faye2008">{{cite encyclopedia | url = http://plato.stanford.edu/entries/qm-copenhagen/ | title = Copenhagen Interpretation of Quantum Mechanics | access-date = 2010-09-19 | last = Faye | first = J | date = 2008-01-24 | encyclopedia = [[Stanford Encyclopedia of Philosophy]] | publisher = The Metaphysics Research Lab Center for the Study of Language and Information, [[Stanford University]]}}</ref>

Bohr emphasized the classical nature of measurement results.
An "irreversible" or effectively irreversible process imparts the classical behavior of "observation" or "measurement".<ref>{{cite book |author=[[Niels Bohr]] |orig-date=May 16, 1947 |date=1985 |series=Niels Bohr: Collected Works |volume=6 |title=Foundations of Quantum Physics I (1926-1932) |editor=Jørgen Kalckar |pages=451–454 |url=https://www.nbarchive.dk/publications/bcw/}}</ref><ref>{{cite book |chapter=To fathom space and time |pages=121 |author=Stig Stenholm | title=Quantum Optics, Experimental Gravitation, and Measurement Theory|editor1-link=Pierre Meystre |editor=Pierre Meystre |publisher=Plenum Press |year=1983 |quote=The role of irreversibility in the theory of measurement has been emphasized by many. Only this way can a permanent record be obtained. The fact that separate pointer positions must be of the asymptotic nature usually associated with irreversibility has been utilized in the measurement theory of Daneri, Loinger and Prosperi (1962). It has been accepted as a formal representation of Bohr's ideas by Rosenfeld (1966).}}</ref><ref>{{cite journal |title=Classical motion of meter variables in the quantum theory of measurement |author=Fritz Haake |date= April 1, 1993 |journal=[[Physical Review A]] |doi=10.1103/PhysRevA.47.2506 |volume=47 |issue=4 |pages=2506–2517 |pmid=9909217 |bibcode=1993PhRvA..47.2506H }}</ref>
