At the core of all science, physics helps us understand chemical reactions, cell transport, the Earth's interior and the life cycle of stars. Among much else, physicists invented the semiconductor, the laser and the electron microscope. They play key roles in the design and operation of spacecraft and in the development of electronic and optical instrumentation. The Department of Physics and Astronomy offers an MS degree in physics and three undergraduate degrees: a BS that prepares students for professional careers in applied physics or graduate study, a BA that combines a strong foundation in physics with a second area of concentration, such as computer science or math, and a BA Preparation for Teaching, for students planning a careers in education. Undergraduates also have the opportunity to minor in physics or astronomy. Our faculty, experts in lasers and optics, computational physics, condensed matter, astronomy and physics education, receive on average $1.8 million annually in external funding for sponsored research.
