Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical ...
A classic monograph by Paul Dirac on quantum mechanics, first published in 1930 and revised several times. It covers the basic principles, methods, applications, and history of the subject, using a logical and concise style.

The author argues that quantum mechanics should follow from a correct and complete mathematics, not vice versa. He presents a new formulation of quantum mechanics based on wave functions, functionals, and quantum elds, and applies it to various physical systems and problems.

A comprehensive and accessible introduction to quantum mechanics, covering mathematical foundations, postulates, symmetries, perturbation theory, and scattering. The book also includes exercises, solutions, and references for advanced undergraduate and graduate students.
Sep 17, 2024 · Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.

The complete theory of quantum mechanics which we now use to describe atoms and, in fact, all matter, depends on the correctness of the uncertainty principle. Since quantum mechanics is such a successful theory, our belief in the uncertainty principle is reinforced.
