- Quantum mechanics - Wikipedia
Quantum mechanics allows the calculation of properties and behaviour of physical systems It is typically applied to microscopic systems: molecules, atoms and subatomic particles
- Introduction to quantum mechanics - Wikipedia
Quantum mechanics is the study of matter and its interactions with energy on the scale of atomic and subatomic particles By contrast, classical physics explains matter and energy only on a scale familiar to human experience, including the behavior of astronomical bodies such as the Moon
- History of quantum mechanics - Wikipedia
So, quantum mechanics is the part of mechanics that deals with objects for which particular properties are quantized The discoveries of the 19th century, both the successes and failures, set the stage for the emergence of quantum mechanics
- Quantum mechanics - Simple English Wikipedia, the free encyclopedia
Quantum mechanics explains how the universe works with things that are even smaller than atoms It is also called quantum physics or quantum theory Mechanics is the part of physics that explains how things move and quantum is the Latin word for 'how much'
- Interpretations of quantum mechanics - Wikipedia
An interpretation of quantum mechanics is an attempt to explain how the mathematical theory of quantum mechanics might correspond to experienced reality Quantum mechanics has held up to rigorous and extremely precise tests in an extraordinarily broad range of experiments
- Measurement in quantum mechanics - Wikipedia
In quantum mechanics, each physical system is associated with a Hilbert space, each element of which represents a possible state of the physical system The approach codified by John von Neumann represents a measurement upon a physical system by a self-adjoint operator on that Hilbert space termed an "observable" [1]: 17 These observables play the role of measurable quantities familiar from
- Quantum mechanics | Definition, Development, Equations | Britannica
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
- Quantum Mechanics | Brilliant Math Science Wiki
Quantum mechanics [QM] is a branch of physics which describes physical systems so that properties like the energy or angular momentum are discrete quantities that are multiples of a smallest unit or quantum
