Sears and Zemansky's University Physics

Roger A. Freedman is a Lecturer in Physics at the University of California, Santa Barbara. Dr. Freedman was an undergraduate at the University of California campuses in San Diego and Los Angeles, and did his doctoral research in nuclear theory at Stanford University under the direction of Professor J. Dirk Walecka. He came to UCSB in 1981 after three years teaching and doing research at the University of Washington.

At UCSB, Dr. Freedman teaches in both the Department of Physics and the College of Creative Studies, a branch of the university intended for highly gifted and motivated undergraduates. He has publishes research in nuclear physics, elementary particle physics, and laser physics. In recent years, he has helped to develop computer-based tools for learning introductory physics and astronomy.

When not in the classroom or slaving over a computer, Dr. Freedman can be found either flying (he holds a commercial pilot's license) or driving with his wife Caroline in their 1955 Nash Metropolitan.

T.R. Sandin is Professor of Physics at North Carolina A&T State University. He received his B.S. in physics from Santa Clara University and his M.S. and Ph.D from Purdue University. He has received awards for excellence in teaching from both Purdue University and NC A&T. He has published research articles in low-temperature solid state physics, the Mossbauer effect, ferromagnetic anisotropy, and physics teaching.
