What is fundamentally quantum? We argue that most of the features, problems, and paradoxes – such as the measurement problem, the Wigner's friend paradox and its proposed solutions, single particle nonlocality, and no-cloning – allegedly attributed to quantum physics have a classical analogue if one is to interpret classical physics as fundamentally indeterministic. What really characterizes non-classical effects are incompatible physical quantities, which, in quantum quantum theory are associated to the fundamental constant ℏ .

The report analyzes the weak absorption problem of the quantum mechanics fundamental laws by the students of the Polytechnic schools and teaching. The problem is that in the famous courses of General physics (including lectures Feynman) emphasizes the exotic nature of quantum mechanics. This section of General physics is presented as a tool for solving only problems in atomic and nuclear physics. This is largely due to the lack of research results of quantum regularities at the macro-processes. The aim of presented study was to search for previously unknown quantum effects in the macro-processes. A positive outcome of these studies would present to students the fundamental and unique features of the quantum approach. In the research the author of this paper was able to establish previously unknown manifestations of quantum regularities in the wind gusts formation. The fundamental nature of these manifestations was obtained for a representative set of geographic points of the Earth. Along with this were used representative data of meteorological observations for the period of over 35 years.

We systematically analyze the conceptual structure of modern physics, i.e., the theory of relativity and quantum mechanics and quantum field theory, from the perspective of Leibniz’s three basic principles of identity, sufficient reason and continuity. We find that Leibniz’s way of thinking can still provide insight into fundamental problems of physics, such as the nature of physical constants, the relation between physical invariances and covariant coordinate representations, the role of the Planck scale and quantum mechanical indeterminism and the measurement problem. Leibniz himself could not possess all those insights, simply because physics was not yet sufficiently developed then, but he had already forged some conceptual tools with which some fundamental problems of modern physics can be addressed.
