History of the phone

"Forgot your phone at home" sounds like a death sentence today. Our entire life is concentrated in our smartphones. Call a taxi, pay in a store, listen to your favorite music, read the news and, of course, arrange a meeting - all this can be done with the press of a couple of buttons. It's hard to believe, but the phone was not always like this. Just twenty years ago, you could only talk and exchange short messages on a mobile phone. Fifty years ago, a home (landline) phone was the only means of communication, but even that was not in every apartment, and you had to run to a payphone in the next block. And there was a time when people lived without a phone at all. How did they communicate with each other then? And who invented devices that transmit sound?
This book is a history of communications from Ancient Rome to the present day. It poses many interesting questions to readers, thanks to which one can observe how science and technology developed in a dialogue between scientists from different countries and eras. What inventions of the past underlie modern technology? How did "dots" and "dashes" help the telegraph? Why does a telephone receiver need carbon powder? What has changed thanks to radio? And how did it become possible to switch from analog to digital? And from "The History of the Telephone" you will also learn about Napoleon's secret semaphore, the radio on board the Titanic, a cable on the ocean floor, and hacking a telephone network with a whistle.
The publication is accompanied by expressive and bright illustrations by the artist Liza Kazinskaya. Here you will find detailed devices and mechanisms, portraits of inventors, and funny genre scenes.
