### Major

A physics major consists of a minimum of 11 courses, usually five core courses, at least four electives, and two courses of research during the senior year. Students should be aware that most physics courses have mathematics corequisites and/or prerequisites, as listed in the course description. Courses above the 200-level typically require a facility with multivariate calculus (normally requiring completion of three courses in mathematics). Each student majoring in physics is expected to acquire a basic knowledge of classical and modern physics by taking a core sequence consisting of two semesters of workshop physics (131, 132 or 141, 142) followed by 211, 212 and 282. Students will then select at least four elective courses tailored to their preparation, interests, and goals. At least two of these must be at the 300-level or above. All physics majors not enrolled in a 3-2 engineering program must complete the senior research sequence 491, 492. In general the introductory courses intended primarily for non-science majors, Life in the Universe (105) and Introductory Astronomy (109, 110) may not be applied towards a physics major.

**Physics-Engineering Track:**

13 courses

PHYS 131, 132, 211, 212, 213, 282, 311, 312, 331 OR 314, 491 and 492

### Minor

**Minor in Physics**

A physics minor is expected to acquire a basic knowledge of classical and modern physics by taking six of the department's course offerings, including a two semester workshop physics sequence (131, 132 or 141, 142) and 212. The remaining three courses required for the minor must be at or above the 200-level. A student may not apply courses used to fulfill the requirements of a minor in physics to fulfill the requirements of a minor in astronomy.

**Minor in Astronomy**

Options are available for students who wish to add an astronomical perspective to a major in any field. The minor consists of the following: 109; 110 OR 208; an astrophysics course at the 300 level or above; three regularly offered courses, independent study, independent research, or internship credits offered by the Department of Physics and Astronomy. One of these courses/experiences may, upon prior approval by the Department, be offered by another department or be an external experience such as a summer Research Experience for Undergraduates. No more than three of these courses or experiences may count toward both the physics major and the astronomy minor.
