The Department of Physics and Astronomy provides a variety of stimulating opportunities to learn about the world around us: from everyday phenomena and modern-day technologies, through the vastness of outer space and minuteness of the nano-realm, to the bizarre quantum-relativistic fabric of physical reality. Fueled by curiosity and dedicated to excellence in teaching and research, Sewanee's physics and astronomy faculty often involve like-minded students in their diverse scholarly pursuits, which include hunting for asteroids and extrasolar planets; nuclear and accelerator physics; biophysics; materials characterization; simulation, fabrication, and optical studies of functional nanomaterials.

At The University of the South, a focused physics education fits naturally within the liberal arts and sciences environment that forms the core of the Sewanee experience. Students who take our physics and astronomy courses develop a robust understanding of fundamental physical principles—the essence of “how the world works”—as well as valuable reasoning, problem-solving, and experimentation skills. Our physics majors also delve into advanced theoretical topics, utilize research-grade instrumentation and data analysis tools, participate in faculty-led and independent research projects, both on campus and at other institutions, presenting their findings at department seminars and national conferences.

University Observatory

The Cordell-Lorenz Observatory is an instructional laboratory for astronomy courses offered by the department of physics and astronomy and also for public observations. Programs throughout the year and open hours every Thursday evening from 8 p.m. until 10 p.m. (weather permitting), while classes are in session, encourage both academic and enrichment activities.

The largest telescope for public observations is a ten-inch Schmidt-Newtonian reflector. There are also other ten-inch and one three and one-half-inch telescopes which are often used, as well as large binoculars. The dome houses a classic six-inch refracting telescope crafted by Alvan Clark and Sons in 1897. It has been restored to its original quality and historical appearance by Dr. Francis M. Cordell Sr. of the Barnard Astronomical Society.

For research purposes, one 0.35 and five 0.30 meter (14 and 12 inches) telescopes on computer controlled mounts are housed in several small roll-off sheds on the roof of Carnegie. These telescopes have sensitive CCD detectors which are used to monitor newly discovered asteroids, comets, supernovas, gamma ray bursts, and variable stars.
