"But then he did something which mathematicians can do... [i.e.,] what-if experiments. You can say... what if these equations have other solutions, and he found... waves with the same speed as light, but a different and than light... and we now call them radio waves. ...Maxwell discovered radio by pure mathematics alone. It was later... that... Hertz found them experimentally, and... later... Marconi and others took the theory and turned it into practical means of communication."
