One of the fundamental tenets of quantum mechanics is that measuring a physical system always disturbs it.
quantum mechanics made fascinating for readers who'd rather skip the mathematical complexities.
Even by the standards of quantum mechanics, this is surprising.
No area of physics stimulates more nonsense in the public arena than quantum mechanics-and with good reason.
Lasers are usually thought of as bright beams of light that rely on quantum mechanics to work.
But in quantum mechanics, you can take all three of these routes simultaneously.

British Dictionary definitions for quantum mechanics
quantum mechanics
noun
1.
(functioning as sing) the branch of mechanics, based on the quantum theory used for interpreting the behaviour of elementary particles and atoms, which do not obey Newtonian mechanics
quantum mechanics A fundamental theory of matter and energy that explains facts that previous physical theories were unable to account for, in particular the fact that energy is absorbed and released in small, discrete quantities (quanta), and that all matter displays both wavelike and particlelike properties, especially when viewed at atomic and subatomic scales. Quantum mechanics suggests that the behavior of matter and energy is inherently probabilistic and that the effect of the observer on the physical system being observed must be understood as a part of that system. Also called quantum physics, quantum theory. Compare classical physics. See also probability wave, quantum, uncertainty principle, wave-particle duality.
