### Major

A physics major consists of a minimum of eleven 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 two 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 Advanced Laboratory Capstone sequence 491, 492 *OR *two semesters of Independent Research (PHYS 550) with senior status and permission of the instructor. The introductory courses intended primarily for non-science majors, Life in the Universe (ASTR 105), Mysteries of the Solar System (ASTR 109), and Stars, Galaxies, and Beyond! (ASTR 110) may not be applied towards a physics major.

### 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: ASTR 109, PHYS 131, PHYS 132, ASTR/PHYS 208, PHYS 212, and ASTR/PHYS 306 *OR* one other astronomy-related course offered in the Physics and Astronomy Department, which may include an independent study, independent research, or internship credit 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. *Note that there are mathematics prerequisites for PHYS 131, 132 and 212.*

We will focus on the standards of the physics and astronomy communities on how research is done. These standards are expressed in statements about Responsible Conduct of Research (such as data acquisition, health and safety in research, mentoring, conflict of interest, and issues of bias). In addition, we will discuss concerns seemingly external to the research, including questions such as how does this research affect the community? Why are we doing this research? How can we deal with unforeseen consequences? Furthermore, we will look at ethics in physics and astronomy outside research, including in education and in business.
