My name is Mark. I am retired from a career in Electronics, Engineering and Technology Management in Higher Education, and related fields. I have spent my entire life wrenching, maintaining and building stuff in a wide variety of technical environments. I'd like to share some of the things I've learned in my lifetime at the elbows of the many brilliant scientists, engineers and skilled tradesmen with whom I've been fortunate to work. I'll also try to cover the Incidental facts that tie together the physics, chemistry, electro-magnetics and history in these fields which we enjoy. Video focus will be largely project oriented and liberally spattered with anecdotes, technical facts or history (maybe a story now and then) about the subject at hand. Hence the name "Incidental Information". These videos are intended to be informative and thought provoking, not entertaining. We hope you enjoy.
