Quantum mechanics - Wikipedia
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 physics cannot.
The quantum world: A concise guide to the particles that make …
Apr 5, 2023 · What you’ll find below is a concise, clear-eyed guide to the known particles and forces – from electrons, quarks, and neutrinos to photons and the Higgs boson – as well as the quantum laws and...
Discovery of new class of particles could take quantum …
2 days ago · Fundamental particles typically fall into two categories. Bosons are particles that can share the same quantum state, meaning many of them can exist together without restrictions. Fermions, on the other hand, follow what’s known as the Pauli exclusion principle, which says no two fermions can occupy the same quantum state.
What is Quantum Entanglement? NASA Science
Learn how particles engage in a mind-boggling phenomenon that forms the backbone of quantum mechanics. The fascinating science of quantum entanglement proposes that particles of the same origin are always connected.
What Is Quantum Physics? - Caltech Science Exchange
Quantum 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.
Quantum mechanics: Definitions, axioms, and key concepts of quantum …
Apr 29, 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.
Quantum mechanics | Definition, Development, & Equations
5 days ago · 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.
Physics - Quantum Mechanics, Particles, Waves | Britannica
Dec 9, 2024 · The four basic forces of nature, in order of increasing strength, are thought to be: (1) the gravitational force between particles with mass; (2) the electromagnetic force between particles with charge or magnetism or both; (3) the colour force, or strong force, between quarks; and (4) the weak force by which, for example, quarks can change ...
DOE Explains...Quantum Mechanics | Department of Energy
Quantum mechanics is the field of physics that explains how extremely small objects simultaneously have the characteristics of both particles (tiny pieces of matter) and waves (a disturbance or variation that transfers energy). Physicists call this the “wave-particle duality.”
