Who was the inventor of the telegraph and why did he invent it?
First, let's learn what a telegram is. Telegraph is the earliest communication method of transmitting information by electricity. It breaks people's spatial distance and transmits information through special communication methods. With the invention of the telegraph, it broke the old long-distance communication methods, such as homing pigeons, believing in dogs, sealing cigarettes and so on. It has brought great changes and convenience to people's lives.
Inventing the telegraph is the general trend. After Hertz invented electromagnetic wave, for a long time, electromagnetic wave was just a simple engineering equation and had no other function. But with Marconi's continuous exploration of electromagnetic waves, he finally invented an upgraded version of the telegraph, that is, wireless telegraph. In 1896, he applied for the commercial patent of his own radio in Britain, and in 1897, he established the radio telegraph Jishun Co., Ltd., and because of this invention in 1909, Marconi won the Nobel Prize in physics.
Why is it the general trend to invent the telegraph? Because the old communication method is very inconvenient. For example, the above-mentioned carrier pigeons, dogs and other long-distance communication methods. They are bound by the conditions of homing pigeons and dogs. If there is an accident in the process of communication, then the communication letter will not reach the people we want, and for a long time, the sender will not know that his letter has an accident. This is very inconvenient for people who have something urgent to contact. Moreover, this traditional communication transmission mode will also be affected by weather conditions. It is impossible to carry out such a long-distance communication transmission under the condition of unsatisfactory weather conditions. Therefore, the invention of the telegraph is the general trend, in order to meet people's needs. It is the symbol of civilization development and the embodiment of scientific and technological progress.
