Physicists are scientists who investigate motion and gravity, the behavior of gases, the structure and behavior of matter, the generation and transfer of energy, and the interaction between matter and energy. They identify basic forces and laws of nature. Theoretical physicists investigate these areas without thought to practical application, concerning themselves with concepts such as the nature of time and the origin of the universe. Other physicists apply their knowledge of physics to practical matters, such as the development of computers, transistors, laser beams, microwave appliances, communications satellites, and a wide variety of other devices. They solve problems in industry, medicine, defense, and other fields. Read more: Physicist
