What’s in a wiggle?

I think it’s truly amazing that if you stick a long wire up into the air, and wiggle a voltage along its length, it can send music to people hundreds of miles away. And this isn’t even a modern miracle – it was a miracle way before I was born. Better still, it’s not even a miracle of man’s invention (… and there are zillions of those) – it’s more a miracle of man’s discovery (electromagetic waves have existed since the universe was very young).
