In contrast to the Copenhagen interpretation we consider quantum mechanics as universally valid and query whether classical physics is really intuitive and plausible.-We discuss these problems within the quantum logic approach to quantum mechanics where the classical ontology is relaxed by reducing metaphysical hypotheses. On the basis of this weak ontology a formal logic of quantum physics can...

Aims: Patients with bipolar disorder often experience disability in terms of cognitive impairments and activity limitations even in remission. However, knowledge is sparse concerning the ability to perform Activities of Daily Living (ADL) during remission. The aim of this study was to (1) investigate the observed and self-reported ability to perform ADL tasks and (2) examine the association bet...

In this work we analyse critically Griffiths’s example of the classical superluminal motion of a bug shadow. Griffiths considers that this example is conceptually very close to quantum nonlocality or superluminality,i.e. quantum breaking of the famous Bell inequality. Or, generally, he suggests implicitly an absolute asymmetric duality (subluminality vs. superluminality) principle in any fundam...

The famous gedanken experiments of quantum mechanics have historically played crucial roles in trying to understand quantum mechanics and in developing the Copenhagen interpretation. They are re-examined here from the perspective of standard quantum mechanics, without a mix of any ontological interpretation. It is shown that, in most of these gedanken experiments, entanglement plays a crucial r...

We report the results of a double-slit-like experiment in the infrared range, which confirm those of a previous one by evidencing an anomalous behaviour of photon systems under particular (energy and space) constraints. These outcomes (independently confirmed by crossing photon beam experiments in both the optical and the microwave range) apparently rule out the Copenhagen interpretation of the...

Karl Popper, though not trained as a physicist and embarrassed early in his career by a physics error pointed out by Einstein and Bohr, ultimately made substantial contributions to the interpretation of quantum mechanics. As was often the case, Popper initially formulated his position by criticizing the views of others—in this case Niels Bohr and Werner Heisenberg. Underlying Popper’s criticism...

Schrödinger’s cat puzzle is resolved. The reason why we do not see a macroscopic superposition of states is cleared in the light of Everett’s formulation of quantum mechanics. 03.65.Bz Typeset using REVTEX 1 Schrödinger argued [1,2] incompleteness of the Copenhagen interpretation of quantum mechanics by showing a paradoxical thought experiment known as “Schrödinger’s cat”: A cat is placed in a ...

The cardinal differences in the theoretical description of classical and quantum particles, contradictions probabilistic (Copenhagen School) deterministic (De Broglie - Bohm theory) interpretation mechanics, features entangled states are briefly discussed. It is assumed that strange properties pair can be explained by localization particles not 3D physical space, but domain a fractal space aris...
