It's nothing much . . .

Today is the birthday of Heinrich Rudolf Hertz (February 22, 1857 – January 1, 1894), physicist, renowned for the discovery of radio waves.  James Maxwell had mathematically predicted their existence in 1864; however, Heinrich Hertz was the first to send and receive radio waves.

Heinrich Hertz's experiments proved that electricity can be transmitted in electromagnetic waves, which travel at the speed of light and which possess many other properties of light. 

His experiments with electromagnetic waves led to the development of the wireless telegraph, radio, television, radar and many of the wireless devices we take for granted today. 

In recognition of his discovery, his name is the term used for radio and electrical frequencies: hertz (Hz), as in kilohertz (kHz) or megahertz (MHz).

“I do not think that the wireless waves I have discovered will have any practical application.” - Heinrich Hertz
