The word physician often leads to confusion because of its spelling. It has to be remembered, however, that a physician is someone who practices medicine - a qualified doctor - while a physicist is one who carries out scientific research in the field of physics, which deals with the theory of gravity, quantum mechanics, and so on. The term physician is one that is found in common use across the United States, although most other countries prefer to use the term doctor, which is more direct and less misleading. To reiterate, a physician is a person who has been trained to carry out a medical check up of a patient, announce the diagnosis of an ailment, and prescribe suitable remedial measures as a form of cure.
