Briefly defined, physics is the science that tries to understand the laws of nature and the relationship between energy and matter.
It might be more appropriate, however, to define physics as a way of thinking rather than as a profession. The field of physics trains students to take a logical, problem-solving approach in whatever situations they might find themselves. Physics students explore concepts and methods of science that can be applied in many different professional areas and research topics.
Some of the better-known careers for physics majors include academic and industrial research, electronics, alternative energy development, communications or the vital area of medical physics. Physicists are in demand for their analytical skills in many financial, fund management and research roles, in law, as weather forecasters, computer programmers, and as physics and science teachers.
