Students curious about how the world works will find that the physics curriculum offers them the opportunity to learn not only about the principal phenomena of the physical world but also how physical theory helps us understand these phenomena. The curriculum emphasizes laboratory work in which students become independent workers formulating and solving their own problems. Students gain the intellectual skill of moving freely to and from the concrete and the abstract. Students assess evidence, follow complex arguments to their logical conclusions, and practice speaking and writing clearly and effectively. The major program may serve as a basis for further study in physics and allied sciences and in engineering and for study leading to professions in education, health sciences and law.

Many careers are open to those who understand some physics. Graduates work as astronomers, engineers, material scientists and physicists in government, industry and universities as well as in geophysics, oceanography, computer science, medical and health physics and in patent law.

The physics department is located in Collins Hall. Individual research space is available and all laboratories are equipped with a wide variety of instrumentation. Students at all levels use computers with sophisticated data acquisition and analysis software. A set of spectrometers are available for studies from the ultraviolet to the far infrared. An X-ray diffractometer is available for materials studies.

8 credits in Physics, 2 in Mathematics, 1 in Computer Science

- PHYS 215 (QA; NW) Introductory Physics I (1)

- One course in Computer Science
- Two additional courses in Physics

PHYS 496, Research Seminar, satisfies the senior year experience which must be completed by all resident seniors. Students intending to do graduate study in Physics should also take PHYS 342 (Wave Phenomena), PHYS 345 (Electromagnetism), and PHYS 453 (Quantum Mechanics). Such students should also consider further mathematical study in linear algebra and complex variables.

Students preparing for careers in engineering or applied science should also take Wave Phenomena and Electromagnetism plus one other course beyond the basic five. Students with other goals in mind may choose their additional three courses from among any of the other physics courses outside the basic five.

- PHYS 215 (QA; NW) Introductory Physics I (1)
- PHYS 236 (QA; NW) Introductory Physics II (1)
- Three additional Physics courses at 300- or 400-level (3)
