'''Physics''' is the branch of [[physical science]] that traditionally deals with [[matter]], [[energy]], [[force]], and [[motion]].  These concepts can be applied to virtually any area of the physical sciences; therefore, physics is often considered to be the most fundamental branch of science.  Indeed, according to [[reductionism|reductionist]] thought, all other branches of science are specialized subdivisions of physics.

Physics can be broadly divided into two major categories:  [[Classical Physics]] and [[Modern Physics]].

Physics can be broadly divided into two major categories:  [[classical physics]] and [[modern physics]]. Physicists generally take one of two approaches to their research: they either practice [[experimental physics]] or [[theoretical physics]].
