en.wikipedia.org/wiki/Quantum_mechanicsQuantum mechanics (QM; also known as quantum physics, quantum theory, the wave mechanical model and matrix mechanics), part of quantum field theory, is a fundamental theory in physics.It describes physical properties of nature on an atomic scale.. Classical physics, the description of physics that existed before the theory of relativity and quantum mechanics, describes many aspects of nature ...
www.britannica.com/science/quantum-mechanics-physicsQuantum 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.
en.wikipedia.org/wiki/Introduction_to_quantum_mechanicsQuantum mechanics is the science of the very small. It explains the behavior 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 science and ...
www.livescience.com/33816-quantum-mechanics-explanation.htmlQuantum mechanics is the branch of physics relating to the very small. It results in what may appear to be some very strange conclusions about the physical world.
plato.stanford.edu/entries/qmQuantum mechanics is, at least at first glance and at least in part, a mathematical machine for predicting the behaviors of microscopic particles — or, at least, of the measuring instruments we use to explore those behaviors — and in that capacity, it is spectacularly successful: in terms of power and precision, head and shoulders above any theory we have ever had.
www.pbs.org/transistor/science/info/quantum.htmlThese were the laws of quantum mechanics, and they got their name from the work of Max Planck. "An Act of Desperation" In 1900, Max Planck was a physicist in Berlin studying something called the ...

He was guided by a mathematical formulation of optics, in which the straight-line propagation of light rays can be ...

www.thoughtco.com/quantum-physics-overview-2699370Quantum physics is the study of the behavior of matter and energy at the molecular, atomic, nuclear, and even smaller microscopic levels. In the early 20th century, scientists discovered that the laws governing macroscopic objects do not function the same in such small realms.
