Professor & Chair of the Department of Physics & Engineering, Southern Adventist University, Collegedale, TN, USA. Visit us! https://www.southern.edu/academics/physics/faculty.html. Love teaching physics, and learning languages (native in English, comfortable in French and Esperanto, adequate in German, functional in Spanish and Russian, dabbler in several more). I've taught physics (and occasionally math) at the university level for 35 years, first in Rwanda, then in the USA, in Texas and now Tennessee, with intervals acting as visiting professor/lecturer in Ukraine, Germany, Argentina. I've also lived in India, Austria, France, Canada, and several U.S. states. Connect with me here: https://www.linkedin.com/in/kenneth-caviness-aa2521a0/.
