There are several pages of technical description to go along with this simple illustration. It's a work of genius, a new way of encoding information, a giant leap called FM radio. Which will be used to sell us stuff, but in stereo! keep on the sunny side, here .
My brain can only interpret the lower half of this as a uterus and ovaries diagram
I'm not sure if you're being sarcastic, maybe halfway, but it really is a work of genius. New encoding methods? Radio actually (can be) a tool of the people, and sound really good now too.
No, totally straight, this was an incredible insight- or maybe application of known science in a new way. I understand just enough of the principles involved to appreciate it. Of course it's old technology now. Still works.
