[Closed] Help me know things that are unknown to me.

Two cups tied together with string, well wifi just uses fine threads that you can't see.

Radios easy, you turn the wee knob thing till theres a click, then you keep turning until you can hear it. 😀

Edit: sometimes the threads touch and you get a double post

wibbly waves wibble electrons in a receiver that turns the wibbling electrons into electronic signals.

think of an oceanic wave hitting a float thats tied to a pontoon. it lifts and falls as the wave passes, and something turns that into information.

It's all done by magic.

Thanks fellas, I'm having that Steven Hawkins bloke round for tea and now I can answer any question he asks.

He's a gobshite, that fella.

We know there are known knowns: there are things we know we know. We also know there are known unknowns: that is to say we know there are things we know we don't know. But there are also unknown unknowns — the ones we don't know we don't know

Although its a bit of a joke, I can't quite grasp how STW can be sent through the air to my phone by WiFi, I just seem to be unable to get an analogy that I can understand..

You can see? You have a vague concept of how vision works? That's down to electromagnetic waves passing through space. Well radio is just the same as that, but with the waves vibrating a lot slower. The radio waver are passing through space in just the same way light does. Of course one significant difference is that light waves are absorbed by most solids, whilst radio waves can to some extent pass through them (which is due to the difference in frequency).

Do you need simpler than that, or do you want to know how WiFi works given radio waves?
