A Short History of the Radio

First the telegraph and, a bit later, the telephone, together with some important discoveries in the field of physiscs contributed, by the end of the 19th century, to the 
birth of the radio as a means of transmitting sound from one place to another. Since 
that time to present day, with all our wireless devices, a long way has been walked! 
Let's explore it a little bit through this brief exhibition. 
It was carried out at I.E.S. de Catabois by late March, 2015.
