The Department of Physics in its curriculum endeavors to provide a unified presentation of all the major areas in physics to fulfill the needs and interests of a variety of students. This presentation is set in a liberal arts context such that, in addition to the ideas, experiments, and theories, the philosophical and cultural implications of physics are considered.

The department offers a comprehensive major designed to prepare students for graduate study in physics, engineering, or related fields. The Physics curriculum also provides for majors in teaching and interdisciplinary programs, as well as the physics component of pre-engineering and other preprofessional programs.

Through its offerings in Curriculum I and II, the department provides distinct courses for the general education of students who are not engaged in science, but who would like to explore physics and astronomy.

It is important that students considering a major in Physics begin their studies with PHY-200/201 in the fall of their first year. The normal sequence of courses through the first two years of the major would then proceed through PHY-220/221, PHY-240/241, PHY-260, and PHY-270/271.

Students preparing for graduate studies in physics or engineering are encouraged to take the following courses in addition to those required for the major: PHY-300, PHY-350, PHY-360, PHY-370, PHY-380, PHY-390, and PHY-399. Also recommended are CHE-107 and MCS-321.

Sequential courses and courses with prerequisites require that prior courses have been completed with a grade of C– or better.

- 9.75 courses in physics, including: PHY-200, PHY-201, PHY-220, PHY-221, PHY-230, PHY-240, PHY-241, PHY-260, PHY-270, PHY-271, PHY-305, and PHY-365.
- One course from another laboratory science (biology, chemistry or geology).

No course graded below C– shall count toward the Physics major.
