Description of the Major. Physicists seek a fundamental understanding of the physical universe. The skills and knowledge gained in studying physics can be applied not just in research but in several applied disciplines as well. The major includes courses in mathematics (the foundation of science) chemistry (for scientific breadth) and physics. In addition to theory courses, both laboratory classes and hands-on research provide the practical training that is relevant to both graduate school or professional work in science and engineering. For students desiring greater breadth (or a double major) there is also the B.A. degree track that allows greater flexibility.

Distinctive Features. Beyond coursework the opportunity to participate in research is available to students in the department. Current research opportunities include thin film superconductivity, astronomy and experimental nuclear/atomic physics. Internships and summer research programs (both on campus and NSF sponsored programs at other institutions) are both available and encouraged. Students are encouraged to participate in an off-campus program during the junior or senior year.

Career Choices. A physics degree provides a solid foundation for a great many careers besides that of research physicist including: science writing, patent law, software development, materials research, nuclear medical science, forensic science, museum education, engineering (mechanical, electrical, process, civil, aeronautical, etc.), medicine, technician, teaching (high school or college).
