Theory and Applications of the Poincaré Group

Young S. Kim came to the United States from South Korea in 1954 after high school graduation to become a freshman at the Carnegie Institute of Technology (now called Carnegie Mellon University) in Pittsburgh. In 1958, he went to Princeton University for graduate study in physics and received his PhD degree in 1961. In 1962, he became an assistant professor at the University of Maryland at College Park near Washington, DC. After going through the academic ranks of associate and full professors, Dr. Kim became a professor emeritus in 2007. This is still his position at the University of Maryland.

Dr. Kim's thesis advisor at Princeton was Sam Treiman, but he had to go to Eugene Wigner whenever he had to face fundamental problems in physics. During this process, he became interested in Wigner's 1939 paper on internal space-time symmetries particles in Einstein's Lorentz-covariant world. Since 1973, his publications have been based primarily on constructing mathematical formulae for understanding Wigner's paper. In 1988, Dr. Kim noted that the same set of mathematical devices are applicable to squeezed states in quantum optics. Since then, he has been publishing papers also on optical and information sciences. These days, Dr. Kim publishes articles on the question of whether quantum mechanics and special relativity can be derived from the same basket of equations.

Sibel Baskal is Professor Emerita of Physics at the Middle East Technical University. She is particularly interested in the manifestations of the Poincare and little groups, and of group contractions in physical sciences. Her research interests extend to current problems in classical field theories, mostly on alternative approaches to Einstein's gravity. She has published more than 30 peer-reviewed papers and is the co-author of three books with Y.S.Kim and M.E.Noz.

Marilyn E. Noz is Professor Emerita in the Department of Radiology at NYU School of Medicine. Over the last more than 40 years, she has collaborated with Professor Kim on relativistic quantum mechanics using two-by-two matrices, harmonics oscillators, and the Lorentz group. She has contributed to over 50 peer-reviewed journal articles in elementary particle physics and optics. She has written three books with Professor Kim and three books with Professors Kim and Bas kal. She continues to do research in elementary particle physics and quantum optics. Professor Noz taught physics at Marymount College, Tarrytown, NY for five years, where she instituted a major in Physics. She then went to Indiana University of Pennsylvania where she taught physics for five years, rotating through most of the graduate and undergraduate courses. In 1974 she went to the New York University School of Medicine where she taught physics to radiology residents and students training to be ultrasound or nuclear medicine technologists. She has about one hundred refereed journal articles in medical related journals, where she used her physics background. Together with her co-author, Professor Gerald Q. Maguire Jr, she has published four books concerning radiation protection in the radiologic and health sciences.
