This article demonstrates the value and practical application of the theory of the hydrogen atom, as the historical importance of this theory. At the same time, questions of quantum mechanics and its connection with the theory of the hydrogen atom.
Written for a two-semester graduate course in Quantum Mechanics, this comprehensive text helps develop the tools and formalism of Quantum Mechanics and its applications to physical systems. It suits students who have taken some introductory Quantum Mechanics and Modern Physics courses at undergraduate level, but it is self-contained and does not assume any specific background knowledge beyond appropriate fluency in mathematics. The text takes a modern logical approach rather than a historical one and it covers standard material, such as the hydrogen atom and the harmonic oscillator, the WKB approximations and Bohr-Sommerfeld quantization. Important modern topics and examples are also described, including Berry phase, quantum information, complexity and chaos, decoherence and thermalization, nonstandard statistics, as well as more advanced material such as path integrals, scattering theory, multiparticles and Fock space. Readers will gain a broad overview of Quantum Mechanics, as solid preparation for further study or research.
The purpose of this work is to retrace the steps that were made by scientists of XX century, like Bohr, Schrodinger, Heisenberg, Pauli, Dirac, for the formulation of what today represents the modern quantum mechanics and that, within two decades, put in question the classical physics. In this context, the study of the electronic structure of hydrogen atom has been the main starting point for the formulation of the theory and, till now, remains the only real case for which the quantum equation of motion can be solved exactly. The results obtained by each theory will be discussed critically, highlighting limits and potentials that allowed the further development of the quantum theory.

The purpose of this theory is to explain the physical meaning of such quantum mechanical phenomenon as stochastic behavior of elementary particles and other quantum objects. With this aim the given theory introduces the concept of natural quantum selection, which includes phenomena described by quantum mechanics, quantum field theory and quantum cosmology. This theory partially unites the fields of study of the above mentioned theories. This theory explains why there is such a magnitude of particle masses and coupling constants of a standard model of a standard model obtained experimentally but not predicted by a model. Предлагается теория естественного квантового отбора, целью которой является объяснение физического смысла такого квантовомеханического явления, как вероятностное поведение элементарных частиц и других квантовых объектов; и одновременно описание динамического механизма тонкой настройки Вселенной, показывающего необязательность для установления и поддержания равновесия между силами взаимодействия и веществом Вселенной конкретных значений произвольных констант стандартной модели физики элементарных частиц, которые получены экспериментально, но не предсказываются моделью.
