Physics

Physics is the science of matter and its motion, as well as space and time. It uses concepts such as energy, force, mass, and charge. Physics is an experimental science, creating theories that are tested against observations. Broadly, it is the general scientific analysis of nature, with a goal of understanding how the universe behaves.

Physics is one of the oldest academic disciplines, and through its modern subfield of astronomy, it may be the oldest of all. Experimental physics began in the Middle Ages and eventually emerged as a modern science during the early modern period. Those who work professionally in the field are known as physicists.

Today, physics is a broad and highly developed subject. Research is often divided into four subfields:

  • Condensed matter physics
  • Atomic, molecular, and optical physics
  • High-energy physics
  • Astronomy and astrophysics

Most physicists also specialize in either theoretical or experimental research, the former dealing with the development of new theories, and the latter dealing with the experimental testing of theories and the discovery of new phenomena. Despite important discoveries during the last four centuries, there are a number of unsolved problems in physics, and many areas of active research.
