Quantum mechanics - Wikipedia
WebQuantum mechanics allows the calculation of properties and behaviour of physical systems. It is typically applied to microscopic systems: molecules, atoms and sub-atomic particles.
Quantum mechanics | Definition, Development, & Equations
Web19 Apr 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.
Introduction to quantum mechanics - Wikipedia
WebQuantum 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. Classical physics is still used in much of modern ...

Web29 Apr 2024 · Quantum mechanics, or quantum physics, is the body of scientific laws that describe the wacky behavior of photons, electrons and the other subatomic particles that make up the universe.
Introduction to quantum mechanics - Scholars at Harvard
WebThis chapter gives a brief introduction to quantum mechanics. Quantum mechanics can be thought of roughly as the study of physics on very small length scales, although there are also certain macroscopic systems it directly applies to. The descriptor \quantum" arises because in contrast with classical mechanics, certain quantities take on only ...

Web10 Jan 2021 · My best answer so far is that quantum mechanics is the study of how small particles move and interact. But that’s an incomplete answer, since quantum effects can be important on...
What Is Quantum Physics? - Caltech Science Exchange
WebQuantum physics is the study of matter and energy at the most fundamental level. It aims to uncover the properties and behaviors of the very building blocks of nature. While many quantum experiments examine very small objects, such as electrons and photons, quantum phenomena are all around us, acting on every scale.
