Today (August 2, 1922) is the Memorial Day of Alexander Graham Bell, who invented the telephone.

 

If we want to know how essential an object is in our life, it is enough for us to imagine a world without that object. For example, can you imagine a world without a phone!! Phones are a monument to their inventor in every home and every office desk. It was Alexander Graham Bell who brought that noble instrument to the world. Alexander Bell was born on March 3, 1847, in Edinburgh, Scotland. He was nicknamed Alexander Graham Bell, along with his family friend Alexander Graham. His father, Alexander Melville Bell, was a professor. The mother is Elisa Grace. His grandfather, who lived in London, his uncle in Dublin, and his father, Alexander Melville Bell, in Edinburgh, all worked as professional elocutions.

 

How do show different sensations by eye movements? How can a deaf person understand what a person is saying with the movement of his lips? Bell's father has written several books on the subject. At the age of eight, Graham became proficient in playing the piano. At the age of ten, he lost the desire to go to school. He devoted his time to reading the piano and researching sound waves rather than studying Latin and Greek. He fell in love with a deaf woman who was engaged in research into converting speech into electrical sounds and married her. Graham Bell's family emigrated to Canada. While living in Boston, Bell set up a school to train deaf school teachers. In which he taught the basics of speech. As his research and knowledge spread, the University of Boston hired him as a professor of speech anatomy.

 

Bell turned on the music on the piano and sent the music a certain distance. Only sounds were transmitted over the telegraph. It seemed to Graham at the age of 18 that he could send talks that way too. So get involved in those efforts. In those days human speech was transmitted by telegrams from one place to another. Those methods were beneficial to his research. In 1875 these efforts were somewhat successful. At first, I was able to send vague speeches. The world's first telephone call in 1876 was made by Bell to his assistant, Watson. The first phrase he spoke on the phone was "Watson, come here, I want to see you". Watson was able to hear these words clearly. But no one cared about the phone that Bell invented so he got very tired.

 

He put his phone in view at an exhibition in Philadelphia. It was only after the King of Brazil took it in stride and used it that the glory of the phone spread everywhere. With the help of his father-in-law in the United States, he received a patent for the phone on March 7, 1876. The word ‘hello’ was first answered by Thomas Edison on the phone. Then it became the standard for answering calls. In 1877 he and his assistant Watson founded a telephone company called the Bell Telephone Company. He set up an organization called the Volta Laboratory with a prize of 50,000 francs from the French government for inventing the telephone.

 

Bell is not limited to the phone. Through the government agency, he invented devices such as photophone, audio meter, metal detector, induction balance, wax recording cylinder, and gramophone. Bell was also involved in trying to find the plane. But it did not win him over. But made some discoveries. Bell was the inventor of the Elyron part of the plane. He later succeeded in reforming the seaplane. Innovated to raise goats. He also planned to create female goats that would give birth to twins each time. He invented a rare tool that could help filter out excess moisture in the air for veterans seeking to roam the desert. He founded the Association for the Development of Speech Training for the Deaf. Bell has done a lot to help Helen Keller, who invented the Braille system for the blind.

 

He was interested in creating world English that was phonologically based. The most important feature of Bell's history is that he holds the patent for 59 discoveries, both privately and with other scientists. When the Second Industrial Revolution blossomed in the nineteenth century, the three great creative geniuses used electricity and radio waves to achieve the development of communication. Thomas Alva Edison, the American genius who refined the telegraph transmitter made by Bell after refining the telegraph transmission system, sent Alex Verraham Bell, the next American genius to invent the telephone, the first American genius to send telegrams over the wire. Marconi was the Italian scientist who created (Wireless Communication). In the twentieth century, telephone, wireless, and television have multiplied, and in the twenty-first century, all forms of communication have become wireless.

 

Edison, Bell, Marconi, and Wright brothers are considered to be the mechanical engineers of the nineteenth-century creation of God. They all explored North American soil and are hailed as the ones who multiplied the mechanical age into the world of alma mater. Alexander Graham Bell, the inventor of the telephone, died in the United States on August 2, 1922, at 75. On the day of his death, all telephones in the United States were stopped for 5 minutes, and tributes were paid. He received the Legion of Honor Award from the French Government, the Volta Prize, the Albert Medal (1902), the Doctorate from the University of Uersberg, and the Edison Medal (1914).
