Noun
the branch of mechanics based on Newton's laws of motion
Source: WordNetPeople get a lot of confusion, because they keep trying to think of quantum mechanics as classical mechanics. Sidney Coleman
The laws of classical mechanics represent a mathematical idealization and should not be assumed to correspond to the real laws of nature. ... We now have to realize that errors are inevitable (..) a discovery that makes strict determinism impossible. Léon Brillouin
Many authors say that classical mechanics stand in opposition to the relativity postulate, which is taken to be the basic of the new Electro-dynamics. Hermann Minkowski
...experimental physics was particularly interested in the processes taking place inside the atom, and in this field the classical mechanics was failing conspicuously and completely. Perhaps its most spectacular failure was with the fundamental problem with the structure of the atom. James Jeans
Arnold Sommerfeld identified this adiabatic invariant as the action variable of classical mechanics. Source: Internet
At the base of classical mechanics is the notion that a body 's motion can be described as a combination of free (or inertial ) motion, and deviations from this free motion. Source: Internet
