Little-known? Who doesn’t know what a faraday cage is?
“Who doesn’t know what a faraday cage is?”
You know what it is. And I know what it is. And likely most folks reading this thread know what it is. But if Jay Leno were standing on Hollywood Blvd with a microphone and interviewing random tourists as they walked by, how many could explain what a Faraday Cage is? Ten percent? Twenty percent? I’d be surprised if it were much more than that. There’s a lot of ignorance out there.
