Between the 1920s and the 1950s, the mathematical results of quantum mechanics were interpreted according to what is often referred to as “the standard interpretation” or the “copenhagen interpretation.
Quantum mechanics is the most well-corroborated theory in physics. The formalism of quantum mechanics does, however, not lend itself easily to interpretation. The bohr-einstein debates highlight some of the di culties in accepting quantum mechanics, and in the recent past it seems as if the attention to the questions concerning the foundations have.
The statistical interpretation of quantum theory is formulated for the purpose of providing a sound interpretation using a minimum of assumptions. Several arguments are advanced in favor of considering the quantum state description to apply only to an ensemble of similarily prepared systems, rather than supposing, as is often done, that it exhaustively represents an individual physical system.
In a nutshell, quantum mechanics tells us that particles like electrons or protons do not have particular properties like position. An electron, for example, has no fixed and definite position.
A fundamental concept in quantum mechanics is that of randomness, or indeterminacy. In general, the theory predicts only the probability of a certain result. Imagine a box of atoms with identical nuclei that can undergo decay with the emission of an alpha particle.
If this is true, quantum mechanics may be a permanent part of physics. Indeed, quantum mechanics may survive not merely as an approximation to a deeper truth, in the way that newton’s theory of gravitation survives as an approximation to einstein’s general theory of relativity, but as a precisely valid feature of the final theory” [37].

Statistical mechanics from quantum mechanics using collisons of microscopic systems to create density matrices that are diagonal in the energy representation. This is very much the same as the classical treatment and boltzmann's h-theorem. In a way these notes extend far beyond interpretation issues, but that is how they started to evolve.
Is it possible to approach quantum theory in a 'therapeutic' vein that sees its foundational problems as arising from mistaken conceptual presuppositions?.
In the beginning there was continuous flow, and then max planck came along and proposed quantization.
Klee irwin, marcelo amaral, and david chester (2020) we modify the simulation hypothesis to a self–simulation hypothesis, where the physical universe, as a strange loop, is a mental self–simulation that might exist as one of a broad class of possible code theoretic quantum gravity models of reality obeying the principle of efficient language axiom.
Recently d’espagnat discussed the philosophical inadequacy of the current interpretations of quantum mechanics (including the standard copenhagen interpretation) in dealing with the paradoxes of quantum measurement (such as schroedinger’s cat and epr-bohm) without, however, suggesting any immediate remedy.
I think none of the current interpretations of quantum mechanics is satisfactory (which seems in line with the fact that no single interpretation dominates all others), though in my view the copenhagen interpretation comes closest.
Lorentz’ answer to larmor’s question surely does not solve all of the problems relating to the interpretation of the electron as a current ring, but it sure answers that very basic question which proponents of modern quantum mechanics usually advance when talking about the so-called failure of classical physics: electrons in some electron.

Nov 1, 2011 “the copenhagen interpretation is like a religious text,” says mit physicist max tegmark.
The most well-accepted interpretation of quantum mechanics is the idea called copenhagen interpretation. This interpretation builds upon the probability-wave notion, but brings in a radical new idea called the superposition principle. The best way to explain this principle is by showing it mathematically.
Asking for a “derivation” of this interpretation as you do is asking for a hidden variables description, which is impossible — for an “alternative” to bohmian mechanics that seems less well known (and fails for different reasons), you might want to look at wetterich’s work on “quantum mechanics from classical statistics.

Quantum suicide is a thought experiment in quantum mechanics and the philosophy of physics. Purportedly, it can distinguish between the copenhagen interpretation of quantum mechanics and the many-worlds interpretation by means of a variation of the schrödinger's cat thought experiment, from the cat's point of view.
Alas, that’s quantum mechanics, and we should probably start getting used to it eventually! the startup.
Exam-ples are displayed of models that are classical in essence, but can be analysed by the use of quantum techniques, and we argue that even the standard model, together with gravitational interactions, might be viewed as a quantum mechanical approach.
Modal-hamiltonian interpretation of quantum mechanics 37 our work on decoherence from a closed-system perspective taught us that the 38 decomposition of the total hamiltonian has to be studied in detail in each case, in 39 order to know whether the system of interest resulting from the partition decoheres 40 or not under the action of its self.
Quantum physics, proposes a new interpretation of quantum mechanics based on chaos theory. A fundamental postulate in the proposed interpretation is the equivalence between the superposed state and a chaotic signal. Though chaotic signals are deterministic, the impracticality of knowing completely and accurately all the initial conditions.
In §4, i show that this way of understanding quantum mechanics is not in conflict with a consistent “single-world” interpretation of the theory.

Quantum mechanics is unlike any other theory in physics in having several plausible interpretations, but no single agreed interpretation.
Interpretation of quantum mechanics even though quantum mechanics has been around for more than a century, there is still considerable dispute about exactly what it means.
The complementarity principle was certainly one of bohr's main tenets of quantum mechanics, so in this sense the copenhagen interpretation is disproved. However, nobody nowadays argues that quantum mechanics predicts anything but the actual outcome of the afshar experiment, so in that sense these are all interpretations of the same theory.
An interpretation of quantum mechanics is an attempt to explain how the mathematical theory of quantum mechanics corresponds to reality.
And so, quantum reality is, as many of baggott’s earlier books, an attempt to bring order to a confounding subject.
