Explore the study of matter, energy and the interactions between the two. Physics is the most fundamental of all sciences, involving the study of matter, energy and the interactions between the two. Physicists seek to understand and control new forms of energy, develop materials for the next generation of computers and improving medical imaging methods, alongside many other areas of study. About half of graduates immediately begin careers. Careers in performing basic research and careers in teaching at universities, however, generally require the additional training obtained with advanced degrees. Therefore, the other half of the students choose to continue their studies in graduate schools
