Scenario about the history of the phone
April 3, 1973. It's a bit cloudy. A well-dressed, middle-aged man was
walking down a street in Manhattan, New York, carrying a small suitcase.

where am i yes me I'm standing in front of your window, Joel.' First, a man
cursed in pain, and then the short sounds of the phone were heard.
The first call from a mobile phone in the history of the world was made in this

As you can see, in this short video we talk about the history of the
telephone.
The person carrying the suitcase was Martin Cooper, head of the
Motorola Corporation's mobile communications department. On the phone, he
spoke with Joel Engel, head of research at AT&T Bell Labs. The two
companies battled for 10 years to create the first mobile phone, with Motorola
winning the battle.

mechanical energy of sound into the energy of electrical signals, transmitting
it over a distance, and converting it back into sound.
Nowadays, we cannot imagine our life without phones. It is most
important to use this miraculous discovery that brings us closer
