`Welcome to the Department of Physics and Astronomy website. We carry out research activities in a broad area, covering the range from constituents of matter at the subatomic and nuclear levels to the formation and evolution of active galaxies. Our CHARA Array is the largest optical/IR interferometer in the world and can be remotely controlled from Atlanta.

In their pursuit of original research, departmental faculty (with postdoctoral fellows, visiting scholars, graduate and undergraduate students) have collaborations and joint programs with scientists in over 15 countries. We take great pride in teaching our undergraduate and graduate students. Our faculty developed an instructional Physics website (Hyperphysics) which receives about 50 million hits per year!
