you mean besides Sex? LOL! I have taught many things over the years, but never physics in a classroom setting. I was a practicing Nuclear Engineer and Physicist for over 18 years before I became a Stock Broker and Registered Investment Adviser. I have taught Communications for many years and am not a bad RF engineer(Self Taught), Taught Marlin Spike, engines and communications for USCGA Safe Boating Classes, Taught Search and Rescue to the State Guard. Reactor Core physics to fellow engineers. Just a few things!
