Vor 3 Tagen · The first complete quantum field theory, quantum electrodynamics, provides a fully quantum description of the electromagnetic interaction. Quantum electrodynamics is, along with general relativity , one of the most accurate physical theories ever devised.
19. 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.
29. 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.
Vor 4 Tagen · Although quantum mechanics is primarily applicable on the scale of atomic interactions, its effects and related phenomena are visible in a wide range of physical systems. An array of plots of the probability density for the electron in its lowest-energy states of the hydrogen atom [5].
Vor 5 Tagen · The uncertainty principle, also known as Heisenberg's indeterminacy principle, is a fundamental concept in quantum mechanics. It states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum, can be simultaneously known.
Vor 6 Tagen · Essentially a wave equation, the Schrödinger equation describes the form of the probability waves (or wave functions [ see de Broglie wave ]) that govern the motion of small particles, and it specifies how these waves are altered by external influences.
23. Apr. 2024 · This paper analyzes the effective field theory perspective on modern physics through the lens of the quantum theory of gravitational interaction. The historical part argues that the search for a theory of quantum gravity stimulated the change in outlook that characterizes the modern approach to the standard model of particle physics ...
