The new mechanics of the atom introduced by Heisenberg may be based on the assumption that the variables that describe a dynamical system do not obey the commutative law of multiplication, but satisfy instead certain quantum conditions. One can build up a theory without knowing anything about the dynamical variables except the algebraic laws that they are subject to, and can show that they may be represented by matrices whenever a set of uniformising variables for the dynamical system exists… 
To Principles of Quantum Mechanics Development
New insight to the principles of the quantum physics development is given. The correct ways for the construction of new versions of quantum mechanics on the second main postulate base are discussed.
Quantization and Quantum-Like Phenomena: A Number Amplitude Approach
Historically, quantization has meant turning the dynamical variables of classical mechanics that are represented by numbers into their corresponding operators. Thus the relationships between
Time and the Foundations of Quantum Mechanics
Quantum mechanics has provided philosophers of science with many counterintuitive insights and interpretive puzzles, but little has been written about the role that time plays in the theory. One
Exclusion Principle And Quantum Mechanics
The history of the discovery of the exclusion principle, for which I have received the honor of the Nobel Prize award in the year 1945, goes back to my student days in Munich. While, in school in
The Dirac equation, the concept of quanta, and the description of interactions in quantum electrodynamics
In this article the Dirac equation is used as a guideline to the historical emergence of the concept of quanta, associated with the quantum field. In Pascual Jordan’s approach, electrons as quanta
Informational approach to the quantum symmetrization postulate
A remarkable feature of quantum theory is that particles with identical intrinsic properties must be treated as indistinguishable if the theory is to give valid predictions in all cases. In the
A formulation for spinless particles, that holds true the formal equivalency of spatial and time particle’s coordinates achieved through the introduction of an auxiliary parameter of evolution, has
Identical Particles in Quantum Mechanics: Operational and Topological Considerations
This dissertation reports our investigation into the existence of anyons, which interpolate between bosons and fermions, in light of the Symmetrization Postulate, which states that only the two
The Compton Effect in Wave Mechanics
The problem of the scattering of radiation by a free electron has been treated by the author on the basis of Heisenberg's matrix mechanics, which was first modified to be in agreement with the
