Biographical note

Roger A. Freedman is a Lecturer in Physics at the University of California, Santa Barbara. He was an undergraduate at the University of California campuses in San Diego and Los Angeles, and he did his doctoral research in nuclear theory at Stanford University under the direction of Professor J. Dirk Walecka. Dr Freedman came to UCSB in 1981 after three years of teaching and research at the University of Washington. At UCSB, Dr Freedman has taught 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 published research in nuclear physics, elementary particle physics, and laser physics. In recent years, he has done extensive work on making physics lectures a more interactive experience by using classroom response systems and pre-lecture videos. In the 1970s Dr. Freedman worked as a comic book letterer and helped organise the San Diego Comic-Con (now the world's largest popular culture convention) during its first few years. Today, 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 with his wife, Caroline, cheering on the rowers of UCSB Men's and Women's Crew. In Memoriam: Hugh Young (1930? 2013) Hugh D. Young was an Emeritus Professor of Physics at Carnegie Mellon University. He earned both his undergraduate and graduate degrees from that university. He earned his PhD in fundamental particle theory under the direction of the late Richard Cutkosky. Dr. Young joined the faculty of Carnegie Mellon in 1956 and retired in 2004. He also had two visiting professorships at the University of California, Berkeley. Dr Young's career was centred entirely on undergraduate education. He wrote several undergraduate-level textbooks, and in 1973 he became a co-author with Francis Sears and Mark Zemansky for their well-known introductory textbooks. In addition to his role in Sears and Zemansky's University Physics,he was the author of Sears and Zemansky's College Physics. Lewis Ford is a Professor of Physics at Texas A&M University. He received a B.A. from Rice University in 1968 and a Ph.D. in chemical physics from the University of Texas at Austin in 1972. After a one-year postdoctoral at Harvard University, he joined the Texas A&M physics faculty in 1973 and has been there ever since. Professor Ford has specialised in theoretical atomic physics ? atomic collisions in particular. At Texas AM he has taught a variety of undergraduate and graduate courses, but primarily introductory physics.
