Classical mechanics and quantum mechanics are subfields of the branch of physics
called mechanics, that deal with two realms of size, the big and the small, respectively. The
border between big and small has not be scientifically defined yet, but almost every object we
deal with can be assigned to a respective group (i.e. galaxies, stars, planets, people, ants, and dust
particles are all big. Atoms, quarks, photons and electrons are all small). Classical mechanics is a
set of physical laws and their corresponding equations that describe/govern the motion and
interaction of big bodies within the universe. These equations are Galilean invariant which
means they do not apply to non-inertial reference frames. Classical mechanics is sometimes still
called Newtonian mechanics because it\'s basis is on the work of Isaac Newton. Classical
mechanics is an approximation of General Relativity in a weak gravitational field. Quantum
Mechanics is a set of physical laws and their corresponding equations that describe/govern the
motion and interaction of small bodies within the universe. Quantum mechanics as we know it is
the Copenhagen Interpretation which has a set of several main principles . There are two widely
taught formulations of QM, the wave formulation (Schrodinger), and the matrix formulation
(Heisenberg). In the most general sense, the equations that describe a baseball being thrown
cannot describe an electron in an accelerator. Likewise, the equations for the electron cannot
describe the baseball. There is a small caveat here though, the quantum statistical expectation
value of the position and momentum obey Newton\'s laws on average.
