Hello all. I'm a retired Electrical Engineer graduated from University of MO-Rolla many years ago, with 8 credit hours short of a second degree in Physics and 4 hours short of another degree in Mathematics, following 4 yrs of US Navy Avionics Technician. I much preferred Electrical Engineering and particularly the applications of Physics and Electromagnetism. I've worked in aircraft applications, communications, industrial computerized and control systems research and development, mining, metals manufacturing, oil & gas refining, the lumber and paper industries, electrical generation and distribution, research and developmental projects and a few tangential areas such as a short term College teaching position in Introductory Physics and Electromagnetism Basics and development of 4 yr Electrical/Electronic Technician Apprenticeship-Training Programs. At the time of my graduation, the half-life of an Electrical Engineering degree was approximately 2 yrs which has led me to a permanent addiction to continued education. This Forum entices me to participate in order to continue feeding that need. Thank you for allowing me to participate.
