Definition To Quantum Mechanics

It is the foundation of all quantum physics including quantum chemistry quantum field theory quantum technology and quantum information science.

Definition to quantum mechanics. A theory of matter that is based on the concept of the possession of wave properties by elementary particles that affords a mathematical interpretation of the structure and interactions of matter on the basis of these properties and that incorporates within it quantum theory and the uncertainty principle. Mechanics is the part of physics that explains how things move and quantum is the latin word for how much. At this level energy mass momentum and other quantities do not vary continuously as they do in the large scale world but come in discrete units or quanta. Classical physics explains matter and energy at the macroscopic level of the scale familiar to human experience including the behavior of astronomical bodies.

Quantum mechanics the branch of physics that deals with the behavior of matter at the level of the atom the nucleus and the elementary particle. Quantum mechanics science dealing with the behavior of matter and light on the atomic and subatomic scale. Quantum mechanics explains how the universe works at a scale smaller than atoms. Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.

It is also called quantum physics or quantum theory. A theory that explains the behaviour of elementary particles both separately and in groups 2. Atoms used to be considered the smallest building blocks of matter but modern science has shown that there are even smaller particles like. A quantum of energy is the least amount possible and quantum mechanics describes how that energy moves or interacts.
