Starting from the fact, revealed by the author in recent publications, that the quantum uncertainty relations (UR) have authentic nonquantum analogs, it is shown that the Planck constant h also has such an analog, namely the Boltzmann constant k. Both h and k are shown to be generic indicators for the stochasticity property of the physical systems. Depending on its connection with h and k, the stochasticity can be onefold or twofold, respectively an intrinsic or extrinsic property. Earlier views regarding the questions of h - k similarity, complementarity, and compatibility are reviewed and shown to be unfounded. Finally, based on the new views on the UR and h and on their nonquantum analogs, some remarks with conceptual implications in the interpretation of quantum mechanics are noted.

This survey tries to investigate the truths and deficiencies of prevalent philosophy about Uncertainty Relations (UR) and Quantum Measurements (QMS). The respective philosophy, known as being eclipsed by unfinished controversies, is revealed to be grounded on six basic precepts. But one finds that all the respective precepts are discredited by insurmountable deficiencies. So, in regard to UR, the alluded philosophy discloses oneself to be an unjustified mythology. Then UR appear either as short-lived historical conventions or as simple and limited mathematical formulas, without any essential significance for physics. Such a finding reinforces the Dirac’s prediction that UR “in their present form will not survive in the physics of future”. The noted facets of UR motivate reconsiderations of associated debates on QMS. Mainly one reveals that, properly, UR have not any essential connection with genuine descriptions of QMS. For such descriptions, it is necessary that, mathematically, the quantum observables to be considered as random variables. The measuring scenarios with a single sampling, such are wave function collapse or Schrodinger’s cat thought experiment, are revealed as being useless ¨inventions. We propose to describe QMS as transmission processes for stochastic data. Note that, for existing quantum debates, the above UR–QMS revaluations, offer a few arguments for lucrative parsimony in approaches of matters. The unlucrative aspects of those debates have to be reconsidered too, probably in more or less speculative visions.

It is revealed the invalidity of the idea that famous Schrodinger's cat thought experiment can be a quantum touchstone. The arguments are: (i) the probabilistic incorrectness in the (over)rating of the subject, (ii) the possibility of imagining non-quantum scenarios but completely similar to that experiment (iii) lack of ratified practical tests having genuine essence (i.e., non-counterfeit). So, the aforesaid experiment appears as a simplistic thought exercise without any notable significance for quantum physics.
