The following article will be useful if you need the Chemistry help or other subject, such as Physics help. Physics is closely related to mathematics. Mathematics provides the language and the physical tools necessary to provide a precise formulation (quantitative) of physical laws and phenomena they entail. This, in turn, makes it possible to verify (or discard) the results predicted experimentally. Although physical interest on a wide variety of systems, some theories are can only be related to physics as a whole and not one of his fields. For example, the theory of classical mechanics accurately describes the movement of an object, but on condition that (1) their sizes are much larger than an atom, (2) that its speed is much lower than the speed light, (3) it is too near a large mass, and (4) is not electrically charged.
The old theories, like Newtonian mechanics, are still subject of research especially with regard to the study of phenomena complexes such as chaos theory.
