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.

Graduate schools often require students take courses similar to PHYS 335 (Thermal Physics), PHYS 345 (Electromagnetism), and PHYS 453 (Quantum Mechanics). Students intending to do graduate study in Physics should consider further mathematical study in linear algebra and complex variables. Students preparing for careers in engineering or applied science should consider taking Wave Phenomena and Electromagnetism plus one other course beyond the basic six. Students with other goals in mind should consult the faculty concerning their choice of elective courses beyond the basic six.

- PHYS 221 (QA; NW) Introductory Physics I (1)
- PHYS 222 (QA; NW) Introductory Physics II (1)
- PHYS 223 (W) Modern Physics (1)
- Two additional Physics courses at 300- or 400-level (2)

The department seeks to meet its program mission through a curriculum that emphasizes the four skill sets.

- Theoretical and computational skills
- Six of the required physics classes provide a broad theoretical foundation for understanding a physical description of the natural world. In addition, one of these classes (thermal physics) has a focus on using computer-based data-acquisition systems, while one of the elective physics classes (Wave phenomena) has a focus on mathematical methods used in physics. The math and computer programming classes provide the students with further theoretical and computational background.

- Laboratory skills
- Three of the required physics classes (intro I, intro II, and modern) consist of both a classroom component and a complementary laboratory component. This allows students to supplement their theoretical knowledge with experience-based learning. In addition, students learn both how to use lab equipment to collect data and how to appropriately analyze and present the data. Two of the upper-level required physics classes (ATEP and SYE) are research based classes, and have been described in detail above.

- Writing and presentation skills
- For all physics classes that contain a lab component, students are required to turn in a lab report in which they describe their methods of collecting data and analyze their results. In addition, two of the required upper-level physics classes (ATEP and SYE) are research based classes that culminate in both a written thesis and an oral presentation. In ATEP, students learn to present their results in writing of various styles, from a technical paper, to a publication-style paper and a thesis. They also learn how to effectively write proposals.

- General research skills
- These skills are emphasized in all of our laboratory components due to the open-ended nature of most of our labs. However, the strongest exposure to research-like projects happens in ATEP and SYE as both courses mimic the full arc of research from the writing of a proposal, to the design and assembly of an experiment, the data taking and analysis, and the final report in form a paper or presentation. Students learn how to pose and solve physical problems on their own. Research skills are also acquired during summer research participation as part of SCRP or an external REU.
