Physics

Hello,
Medical physics (also called biomedical physics,medical biophysics or applied physics in medicine) is, generally speaking, the application of physics concepts, theories and methods to medicine or healthcare. Medical physics departments may be found in hospitals or universities.
In the case of hospital work, the term medical physicist is the title of a specific healthcare profession, usually working within a hospital. Medical physicists are often found in the following healthcare specialties: diagnostic and interventional radiology (also known as medical imaging), nuclear medicine,radiation protection and radiation oncology.
University departments are of two types. The first type are mainly concerned with preparing students for a career as a hospital medical physicist and research focuses on improving the practice of the profession. A second type (increasingly called 'biomedical physics') has a much wider scope and may include research in any applications of physics to medicine from the study of biomolecular structure to microscopy and nanomedicine. For example, physicist Richard Feynman theorized about the future of nanomedicine. He wrote about the idea of a medical use for biological machines (see nanobiotechnology). Feynman and Albert Hibbs suggested that certain repair machines might one day be reduced in size to the point that it would be possible to (as Feynman put it) "swallow the doctor". The idea was discussed in Feynman's 1959 essay- There's Plenty of Room at the Bottom.

Private Sector Jobs after M.Sc Physics
There are many opportunities available in IT field for M.Sc Physics graduates. Many IT companies such as Infosys, Wipro and CTS are recruiting M.Sc Physics graduates for software jobs. They can also get jobs in Energy Plants. Another job available for these graduates is Technician in Electronic Industry. They can apply for jobs in many companies in automobile industry. Some of those companies are Maruti Udyog, TATA Motors and Tech Mahindra.
Government Sector Jobs after M.Sc Physics
There are vast opportunities available for M.Sc graduates in Government sector. They can apply for jobs in Scientific Research and Development Organizations such as The Defence Research and Development Organisation (DRDO), Physical Research Laboratory Ahmedabad, Saha Institute of Nuclear Physics Kolkata and Nuclear Science Centre New Delhi. They can also apply for various jobs in government organizations given below.
