2013-2014 Academic Catalog

**Chair:** Dean Langley

**Faculty:** James Crumley, Todd Johnson, Thomas Kirkman, Dean Langley, Adam Whitten, Matthew Wiebold, Sarah Yost

The program of study at Saint Benedict's and Saint John's is planned to keep students abreast of the latest developments in the study of physics. The curriculum covers the basics of classical and modern physics, examining human understanding of nature from elementary particles to the cosmos.

Physics majors choose from a sequence of courses that can give them excellent preparation for graduate school, industrial research, secondary teaching or professional studies such as engineering, law and medicine.

For majors in the other sciences, 105, 106 and 191, 200 and 211 offer an introduction to the principles of physics at different mathematical levels: 105 and 106 make use of high school level algebra, geometry and trigonometry; 191, 200 and 211 require concurrent registration in calculus and linear algebra.

Physics is a valuable study for non-science majors, too. The department offers courses (101-3, 150, and 187) which have been developed specifically to suit the needs of non-science majors. No previous introduction to physics is necessary, and mathematics is used sparingly.

The department's experimental facilities include radon monitors, gamma-ray analyzers, electromagnets, a superconducting magnet, diffusion pump vacuum systems, a variety of lasers, fiber-optics and interferometry equipment, a holography system, cryostats, and many new electronic instruments. Computing facilities include Windows PCs in laboratories and classrooms, a computing lab containing dual screen Linux PCs.

The department also maintains shop facilities for metal and woodworking, a photographic darkroom and an electronics shop. Students are encouraged to work independently. Many select their own experimental projects, build special apparatus and perform original measurements.

The Physics Department takes several steps to ensure that we are doing a good job of preparing our students; seniors take the Major Field Test in physics, for example, and those planning on graduate school take the graduate record exam in physics. Overall, however, we believe that the performance of our students after they leave us is the most telling measure of the effectiveness of our program. Our students go on to engineering schools, graduate schools in physics and engineering, government and industrial laboratories, and the like. We do our best to keep in touch with our former students, find out how well they are doing and how good a job we have done of preparing them. We use this information, among other sources, in periodic reviews of our program.

The physics department offers concentrations in physics and applied physics.
