Cardwell Hall houses the Department of Physics, Department of Math and a math and physics library. Unusual features of this building include the James R. McDonald Laboratory, which houses a Tandem van de Graff accelerator, atomic superconducting linear accelerator, an EBIS source of highly ionized atoms, and equipment for studying atomic collisions. Students can view the location and movement of celestial bodies from the fully equipped planetarium and the rooftop astronomical observatory.
