Wireless everything. Its magic. RF magic.
I notice that my wireless internet still works when I move. The signals my device receives are everywhere.
We're surrounded at all times by invisible porn.
I took graduate courses in RF physics.
It's magic.
I worked with someone that's been designing RF circuits close to 4 decades. They reckon it's only about 50% magic.
They are a wizard and they are lying
They are a wizard, yes. Nobody in their right mind would want to do it for so long.
They also reckon the other 50% is trying to harness the magic by randomly tweaking stuff in the hope it doesn't blow up in their face...
I studied electronics, and today I work in IT, specializing in networking. I have no fucking idea why RF, let alone wifi, works. I mean understand how it works, but the why-part is magic, trust me.
The "how" part gets murkier the deeper you dig.
The "why" is because we like magic things.
Picture a rock getting thrown into a body of water and its ripples. Now just scale that up to 3 dimensions and all materials and you have RF!
