Review of: "Fundamental Issues and Measurement Problem in Quantum Mechanics"

The author addresses the classic "Measurement Problem" in Quantum Mechanics (QM) by proposing a resolution based on a categorical distinction between the mathematical elements of the theory.The central thesis suggests classifying physical quantities into two distinct types: Type A (Real Quantities): These correspond to observables that result in speci c eigenvalues in a single measurement.According to the author, only these possess ontological reality at the level of the individual event.Type B (Theoretical Quantities): These include the Wave Function ($\psi$) and the State Vector.The author argues that these are not real physical objects associated with an individual particle, but rather statistical tools describing an ensemble of systems.From this perspective, the article argues that the "collapse of the wave function" is a pseudo-problem.Since the wave function was never a real physical entity of an individual system, it does not physically "collapse"; it merely ful lls its role of predicting probability distributions. Original ContributionsThe article attempts to distinguish itself by formalizing an epistemological separation often left implicit in statistical interpretations.The main contributions include: Qeios qeios.
