Physical experiments result in measurements, which are compared with the outcome predicted by theory. Its laws are typically expressed with economy and precision in the language of mathematics.īoth experiment, the observation of phenomena under conditions that are controlled as precisely as possible, and theory, the formulation of a unified conceptual framework, play essential and complementary roles in the advancement of physics. Physics can, at base, be defined as the science of matter, motion, and energy. Physics plays an important role in all the natural sciences, however, and all such fields have branches in which physical laws and measurements receive special emphasis, bearing such names as astrophysics, geophysics, biophysics, and even psychophysics. As the modern sciences developed and became increasingly specialized, physics came to denote that part of physical science not included in astronomy, chemistry, geology, and engineering. Until rather recent times physics and natural philosophy were used interchangeably for the science whose aim is the discovery and formulation of the fundamental laws of nature. Its ultimate objective is the formulation of a few comprehensive principles that bring together and explain all such disparate phenomena. Its scope of study encompasses not only the behaviour of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels. Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe.
