Is Innovation always good?(Telegraphs/Telephones)
When was the first invention of telephone?
The Italian innovator Antonio Meucci was the first one who were credited for the first ever invention of basic phones in 1849. After that, Frenchman Charles Bourseul devised a phone in 1854, and Alexander Graham Bell won the first ever US patent for his invention at 1876.
How did the first telephone look like?
It's name was the Sound Telegraph. It had a round cone on the front attached to a metal material. Behind there was a hose-looking black metal on the back. If you attach your lips to the cone, you would be able to pass messages from people to another. It looks very different from our phones we have today.
How did it work?
It works by transmitting electrical signals through the wire laid between the stations of the telegraph. They are used to receive Morse code messages. The messages travels as a series of electrical pulses through a wire. The arm of the telegraph will make a "Click!" noise when it strikes a crossbar and the operator will translate the pattern of sounds into the original language
Improve businesses
The telephone offers a more personal touch, allowing businesses the opportunity to communicate with customers. It cut down on the amount of time it took to send messages to each other. As the telephone network grew, it also expanded the area that a business could reach.
Connect with people
Telephones have ability to allow one to contact another person at any time any place with confidence that the call would be completed. The less time it took to communicate was a big draw for society because messages could be sent instantly.
Colleges or people far from home could call and communicate with their families at the other side of the world
Telephones has also changed our attitudes and expectations. If people are late to a meeting, they are expected to notify others by calling on their telephones.
easier communication in wars
Communicating with your allies while knowing where your enemies are is one
of the most crucial parts in war.
During WWI, on the Western Front, telephones were used to communicate between the front line Marines and Soldiers and their commanders
Advantages in using Sound Telegraphs
The telegraph allowed communications over long and short distances. The technology connect different cultures, areas and religions, and geographical movement was not required to send or receive messages. It allowed for the interconnection of towns, which served as stations, and enabled the system to cover a wider area.
Collaborations between countries. Because it connected different traditions, cultures and religions, it made different continents to collaborate in things in developing each other's countries. Countries also got to improve on their economies since customers who would buy it's product increased.
Disadvantages in using Sound Telegraphs/ how it harmed humans
Slow speed. Because each letter had to be converted into Morse Code and keyed by hand, humans that day had struggles in transferring messages. Telegraph transmission took much longer than electronic communication methods used today.
Message length and access. Due to the conversion time of a message, the length of telegraphs needed to be relatively short, making them useful only for very short and concise messages. Access to telegraphs was another issue. Some towns had them, and some didn’t. Unlike the telephones that are commonplace today, telegraphs were rarely used outside of government, business and other large institutions.
Telephones use radiation (RF) to send signals. RF is different from other types of radiation (like x-rays) that we know can be harmful. There are chances it could cause health problems years later. The radiation could make the cells in blood vessel walls shrink, allowing potentially harmful substances in the blood to leak into the brain.
Who invented the first telephone
Alexander Graham Bell was the first to have ever created a telephone. Alexander Graham Bell was born on March 3, 1847. Graham Bell’s father was a professor of speech elocution at the University of Edinburgh and his mother was an accomplished pianist.
Young Alexander was an very curious child who studied piano and began inventing stuff at an very early age. Both of his brothers passed away by the time Bell was in his twenties.
About his education
Initially, Bell’s education was mostly homeschooled. Bell do very well academically, but he was a good problem solver from an early age. When he was around 12, he invented a machine that could quickly remove husks from wheat grain to help farming process. At 16, Bell began studying the mechanics of speech. He attended Royal High School and the University of Edinburgh. In 1870, they moved to Canada.
The next year, he settled in the United States. While in the U.S., Bell implemented a system his father developed to teach the children that are deaf called “visible speech” it is like a set of symbols that represent speech sounds.
Telephone
In 1871, Bell started working on the Sound telegraph(Telephone), a device that allowed more than one messages to be transmitted over a wire at the same time. While he was trying to perfect this technology, which was backed by a lot of investors, Bell became preoccupied with finding a way to send our voice over wires.
By 1875, Bell, with his partner Thomas Watson, had come up with a simple receiver that could turn electricity into sound.
