I have to admit, you electronics guys inhabit a different world for someone whose knowledge of electronics is negligible. My greatest achievement was to build a crystal set that worked when I was about 13, although I had no idea how it actually functioned. It motivated me to look at valve radio circuits in a book my dad had in an effort to build something better, but that went nowhere. To this day I'm amazed that anyone can figure out how those black boxes work, how to track down problems when they don't, and how to design new products. I'm glad someone knows how it all works.
