Sibel Başkal is a physics professor at the Middle East Technical University. 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 two books with Young S Kim and Marilyn E Noz. Young S Kim graduated from Princeton University in 1961 and has been a faculty member of the University of Maryland since 1962. As a well-respected and learned physicist, he has published numerous works throughout his extensive career and continues to work closely with pupils and colleagues as well as continuing his own research in particle theory, quantum mechanics and further contents of Einstein’s work. Marilyn E Noz is a professor emerita in the Department of Radiology at the NYU School of Medicine. Over more than 40 years, she has collaborated with Kim on relativistic quantum mechanics using two-by-two matrices, harmonics oscillators and the Lorentz group. She has contributed to more than 40 peer-reviewed journal articles in elementary particle physics and optics. She has also written three books with Kim and two books with Kim and Başkal, and continues to do research in elementary particle physics and quantum optics.
