Quantum physics are the laws used to govern the goings on in the realm of the micro because Newtonian physics (the old physics) do not apply to this realm. Quantum mechanics are based on statistics...
Quantum physics looks at the world of physics in terms of 'packages', or particles.Ie, gravity acts the way it does do to the behavior of the 'gravitron', which is a quantized measurement.
Quantum Mechanics is a branch of physics describing the behavior of energy and matter at the atomic and subatomic scales. It explains it itself and Quantum Physics is the same deal. They're just two...
first drawback is when speeds are compared..conceptual physics deals with bodies moving at speeds relatively lower than that of light...but many a basic sub-atomic (elementary) moves with terrestrial...
