Physics

Classical physics is generally concerned with matter and energy on the normal scale of observation, whereas modern physics is concerned with the behaviour of matter and energy under extreme conditions or on the very large or very small scale. In classical physics, time and space are absolute and independent, so time and space can be treated distinctly. However, in case of modern physics, time and space are relative and dependent. Between the Branches of classical and modern physics we can highlight acoustics, optics or mechanics in the most aboriginal field, and cosmology, quantum mechanics or relativity in the most current applications.
