The Department of Physics and Astronomy offers two majors: Physics and Astrophysics.
Physics is the study of how objects interact, move and change. It covers objects as small as sub-atomic particles, such as quarks, to as large as the universe. It is inherently an experimental endeavour. The starting and ending points are the data and observations. From experiments and observations we develop fundamental theories that allow us to explain phenomena as commonplace as the flight of a baseball to as exotic as an electron travelling at a speed close to the speed of light.
Courses within the department seek to help students develop a deep understanding of fundamental concepts, problem-solving skills, oral and written communication skills, experimental skills and the ability to work independently as well as with others. The skills learned in studying physics translate well to many fields and careers.
Recent physics majors have gone on to graduate school in physics, astrophysics and engineering, to medical and law school and to careers ranging from teaching to working on Wall Street.
The department participates in dual-degree programs, in which students receive a B.A. from the College and a B.S. in engineering from the partner institution, with Case Western Reserve, Columbia University, Pennsylvania State University, Rensselaer Polytechnic Institute, and Washington University. Students interested in any of these programs are urged to discuss them with the department chair and the Engineering Professions Adviser in the Office of Student & Post-Graduate Development early in the planning of their academic programs.
Students considering a major in physics or astrophysics would normally take Physics 111 and Mathematics 109 or 110 in their first semester, and Physics 112 and Mathematics 110 or 111 in their second semester. However, students have successfully completed these majors following other paths.
To be considered for departmental honors, in addition to meeting the College’s general requirements, a graduating senior must have an excellent record in required courses and complete a two-semester independent study project.
A major in Physics consists of 14 courses:
PHY 111, 112, 223, 226, 331, 333, 344, 421, 432; and either PHY 222 or 224
MAT 109, 110, 111, and 229.
A minor in Physics consists of six courses in the department:
Physics 111, 112, 223 or an approved substitute; 226; 333; and one additional Physics course above the 100-level.
The astrophysics major focuses on physical principles as they are applied to the study of the cosmos. The goal is to promote an understanding of a diverse array of extraterrestrial phenomena in terms of the fundamental physics principles on which this understanding is based. These phenomena range from the very small, such as the reactions between sub-atomic particles that power stars, to the very large, including the expansion and evolution of the universe itself. The astrophysics major emphasizes the same understanding of fundamental physical concepts and skills as the physics major and both majors provide the necessary grounding and background for advanced study in the sciences.
Students interested in a career in astronomy should complete an astrophysics major, or a physics major with a 100-level and at least one 300-level astronomy course as electives.
A major in Astrophysics consists of 15 courses:
PHY 111, 112, 223, 226, 333, 331; and either PHY 222 or 224;
AST 121, 421; and two of AST 312, 322, 332;
MAT 109, 110, 111 and 229.
Majors and minors in the Department of Physics and Astronomy have studied abroad in the following programs in recent years: Institute for Study Abroad, Butler University programs in Scotland, Australia, England, Ireland and New Zealand; TASSEP (Trans-Atlantic Science Student Exchange Program). See the International Programs section of the Catalog for further information.
