Science: Heinrich Hertz; electricity et al.

This geezer was The Man! In his day, he was feted & lived a glutinous, drunken life, before finding his masterpiece which we all associate within or without. Take a magnet, the fix a couple of meters that are fixed to some ferrous metal balls with caterpillar tracks that move the balls back & forward. This made arc lighting & such. So nowadays we register the voltage of electric magnetisms in hertz. Keep'emPeeled
