Copenhagen interpretation of quantum

The answer to this question depends on the chosen, underlying theory. According to the Copenhagen interpretation of quantum physics, the wavefunc-... 

In the Copenhagen interpretation of quantum theory, this standard (see Fig. 21) for the measurement cannot be changed at will since it is composed of sinus waves infinite in length. 

The orthodox or Copenhagen interpretation of quantum theory originated with three seminal papers published in 1925-26 by Heisenberg, Born and Jordan and an independent paper by Dirac (1926) all of these are available in English (translation) in a single volume [13]. A detailed summary was published by Heisenberg [9]. The primary aim of these studies was to formulate a mathematical system for the mechanics of atomic and electronic motion, based entirely on relations between experimentally observable quantities. An immediate consequence of this stipulation was that the motion of electrons could no longer be described in terms of the familiar concepts of space and time, but rather in terms of state functions constructed from matrix elements that relate to the Fourier sums over observed spectroscopic frequencies. The procedure became known as matrix mechanics. 

It is interesting to note that the Gottingen school, who later developed matrix mechanics, followed the mathematical route, while Schrodinger linked his wave mechanics to a physical picture. Despite their mathematical equivalence as Sturm-Liouville problems, the two approaches have never been reconciled. It will be argued that Schrodinger s physical model had no room for classical particles, as later assumed in the Copenhagen interpretation of quantum mechanics. Rather than contemplate the wave alternative the Copenhagen orthodoxy preferred to disperse their point particles in a probability density and to dress up their interpretation with the uncertainty principle and a quantum measurement problem to avoid any wave structure. 

What we perceive to be physical reality is actually our cognitive construction of it. This cognitive construction may appear to be substantive, but the Copenhagen Interpretation of Quantum Mechanics leads directly to the conclusion that the physical world itself is not.9... 

The linear superposition principle plays a central role in the theory presented here. It should be noted, however, that the standard Copenhagen interpretation of quantum mechanics is not well adapted to discuss the notion of state amplitudes and measurements in the context required by the GED scheme. A more appropriate theoretical framework for quantum measurement is found in the ideas proposed by Fidder and Tapia [16]. 

However, the problem of A in particle physics remains. It can be traced back to the concept of massive indivisible point particles with infinite self-energy and self-field - the basic premise of field theories based on the Copenhagen interpretation of quantum mechanics. As recollected by one pioneer... 

The months which followed [... ] were a time of the most intensive work in Copenhagen, from which there finally emerged what is called the "Copenhagen interpretation of quantum theory," [... ] BOHR intended to work the new simple pictures, obtained by wave mechanics, into the interpretation of the theory, while I for my part attempted to extend the physical significance. ... 

The Copenhagen interpretation of quantum mechanics looks like an exception, but part of a claim like Papineau s may be the plausible bet that nothing like the Copenhagen interpretation of quantum mechanics will appear in a completed physics.
