Social science is a major category of academic disciplines, concerned with society and the relationships among individuals within a society.
Continue reading... Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated, Classical mechanics can still be used for many everyday problems with bigger and slower moving objects.
1 Quantum mechanics: a subset of physics explaining the physical behaviours at the molecular, atomic and sub-atomic levels. 2  Old quantum theory under the Bohr model or a theory. 3  Quantum field theory, a generic type of relativistic quantum theory, which includes:
