Electrical Engineering
I earned an Extra Class Amateur Radio License, which I have kept current; spent 6 years in the Navy as a Radio, Radar, and Security Technician, being promoted to 1st Class (E6) before my honorable discharge; and spent my spare time during the summer between my 2nd and 3rd undergraduate years reading all 3 volumes of "The Feynman Lectures on Physics". The professor supervising my Master's thesis was a big fan of Richard P. Feynman, too.
Then I spent a few decades in various R&D and production jobs until retirement.
