So close
In an electrical telegraph shop in France, there was a telegraph engineer called Charles Bourseul. He created one of the first known designs for a telephone… but hadn’t worked out how to convert sound back so it could be understood
How would society survive without the telephone? And how did the evolution of the telephone evolve essentially from 2 tins and a piece of wire, to the global mobile phone network we have now?
Rachel & Melanie take you on an exciting journey of discoveries and failures of the evolution of the phone that includes travel into the space, in the journey of how we have telephones today. And in a world where there are more phones than there are people, what sort of strain does that put on our planet?
