The Victorian Internet by Tom Standage provides a comprehensive history of the invention and development of the telegraph, beginning with the communication devices that set the stage for the “modern” telegraph and ending the with its demise. The changes that were introduced the telegraph were disruptive in nature to society, and had similar impacts that we experience from the internet today (though on a much smaller scale). However, these changes did not occur all at once, they were slowly realized through technological innovations and culture change. The message of the telegraph as a new medium for communication took decades to come to full fruition and innovators had to fight hard to advance scientific knowledge and overcome societal issues …show more content…
Up until this point, there was simply no way in which to communicate more quickly than the fastest horse or boat. The device relied on mechanical arms atop a tower on a hill that were positioned in a specific manner and a codebook for the corresponding messages. The system required a line of sight between transmission towers and there was a finite limit on the variety of messages that could be sent. At first it was used almost solely for military communication. This primitive method caught on quickly and transmission towers started popping up all over France and Europe.
It wasn’t until the mid-19th century that Samuel Morse demonstrated the capability of his electric telegraph to send messages along a wire via electrical pulses using Morse code. The invention was commercialized in the US and a similar method sprung up in the UK. However, public employment of the telegraph was rough at the start. People were unable to understand the device, much less comprehend the implications associated with it. Once the full utility was realized, the new medium caught on quickly and telegraph lines were expanded exponentially as public use sky

Wireless is a methodical account of the early development of wireless telegraphy and the inventors who made it possible. Sungook Hong examines several early significant inventions, including Hertzian waves and optics, the galvanometer, transatlantic signaling, Marconi's secret-box, Fleming's air-blast key and double transformation system, Lodge's syntonic transmitter and receiver, the Edison effect, the thermionic valve, and the audion and continuous wave. Wireless fills the gap created by Hugh Aitken, who described at length the early development of wireless communication, but who did not attempt "to probe the substance and context of scientific and engineering practice in the early years of wireless" (p. x). Sungook Hong seeks to fill this gap by offering an exhaustive analysis of the theoretical and experimental engineering and scientific practices of the early days of wireless; by examining the borderland between science and technology; depicting the transformation of scientific effects into technological artifacts; and showing how the race for scientific and engineering accomplishment fuels the politic of the corporate institution. While the author succeeds in fulfilling these goals, the thesis, it seems, is to affirm Guglielmo Marconi's place in history as the father of wireless telegraphy.
The urgency of communication was never much felt until the beginning and use of telegraphy. It was much easier to transmit and receive messages over long distances that no longer needed physical transport of letters.
He used a comparison pattern to describe telegraph invention with the internet, and how was more important to invent this device similar to the internet invention. Reading through the book gives a different criterion of the implementation and evolution of the telegraph device in Europe and United States. Although Standage’s book lacks deep technical aspects, he tells the story of telegraph invention in simple and interesting chronical way. In fact, he started his first chapter by mentioning the rumors of inventing a magical device to transfer letter between people mile apart in the late of the sixteen century. By 1791 two French scientist brothers Claude and Rene Chappe invented the first version of the Telegraph. The working principle of this device was mechanical and optical, which had failed in the dark. The Chappe brothers continued their trials until 1793 they succeeded to invent the first dependable device to transmit messages over long distances. At this time, the telegraph first named tachygraph from the Greek word tachy which means fast, then they changed to telegraph. The new invention became fully operational by 1794, where it played an important role to send a report of the capture of town from the Austrians and Prussians. The success of using the telegraph in civilian and military matter encouraged Napoleon to build wider telegraph network by 1804. During the nineteen century, the telegraph machine evolved to a wider global communication network to cross the continents especially in England and the United States, where Samuel Morse developed a newer version of the telegraph by
Samuel Morse contributed many things to American society. In 1832 when returning from Europe from a period of art study on the ship Sully, Samuel overheard a conversation about the newly discovered electromagnets and came up with the idea of an electric telegraph. By 1835 he had his first telegraph model working in the New York University building. In 1837, he acquired two partners to help him develop his telegraph. Leonard Gale and Alfred Vail were the two men that he chose. They applied for a patent in 1837 for the telegraph, which included the dot and dash code.
Morse was a very friendly guy. Being a natural leader, he was a founder and the first president of the National Academy of Design, but was lost his campaigns to become mayor of New York or a Congressman. In 1832, while returning on the ship from another period of studying art in Europe, Morse heard a conversation about the newly discovered electromagnet and got the idea of an electric telegraph. He mistakenly thought that the idea of such a telegraph was new, helping to give him the go ahead and push the idea forward. By 1835 he probably had his first telegraph model working in the New York University building where he taught art. Being poor, Morse used materials like an old artist's canvas stretcher to hold his invention, a home-made battery and an old clock-work to move the paper on which dots and dashes were to be recorded.
The Underground Railroad ran through many states starting in the south and running through the North. The railroad helped many slaves escape slavery and start a new life with new found freedom. Since the Underground Railroad is an important part of history, and it helped lead to the ending of slavery it has a immense impact on society as it is today. Society was impacted vastly by the use of the Underground Railroad.
Samuel Morse was born on April 27, 1791 in America. His father was a Calvinist preacher. When Morse was young he went to Yale University to study philosophy and mathematics. In 1811 Samuel traveled to England to study painting. While he was there he became a skilled artist. One hobby Morse had was creating helpful inventions. He became so interested in his inventions that he put off painting, which was his life long carer, to work on them. One thing he wanted to accomplish was to be able to send messages over long distances at lighting speed. After a long time, Morse finally invented a device that would send a message over a long distance. The way it worked was when you tapped a button on the machine electricity was sent through a wire to a
Communication was largely relegated to envoys, land mail, and letters carried on ships before the development of the telegraph. These methods of communication took as "little" time as a few weeks, or as much time as a few months to reach their intended recipient. This is less than ideal because it does not allow vital information, such as political and military occurrences, to be relayed in time for government officials to provide feedback and advice on the matters at hand. The delayed delivery also makes it so that leaders may not have an accurate understanding of the current status of the party that is sending the message. In an area that was as unknown as Africa, being knowledgeable about the current status of the colonies was paramount. The telegraph, couples with the undersea cable, made it so information, such as "commercial and military requirements, administrative decisions, and news" could be relayed in the span of a few hours. In conjunction with the addition of transportation infrastructure, particularly railroads, goods and troops could be relocated to areas of higher need in far less time than before the Industrial
Cell phones have immensely changed the way people communicate today. A cell phone can be all a person need for interaction. From a cell phone, a person can make calls, send text messages, emails, and send and also receive directions, buy things online, do online banking, listen to music and much more. Since someone can do everything with one device, there is no longer a need to go around with multiple devices about. Greek hydraulic semaphore systems were used as early as the 4th century. The hydraulic semaphores, which functioned with water filled containers and visual signals, functioned as optical telegraphs. However, they could only apply a very limited range of pre-determined messages, and as with all such visual telegraphs could only be deployed during good visibility conditions. Experiments on communication using electricity was carried out in 1729 but was not successful. The experiment was proposed by William Fothergill Cooke. In 1837, William invented a practical electric telegraph which entered commercial use in 1838 (J. B. Calvert, May 2004). The first telephone was invented in 1878 by Alexander Graham Bell. He experimented with a ‘phonautograph’, it is a machine shaped like a pen that can draw shapes of sound waves on smoked glass by tracing vibrations.
On March 10th, 1876, a revolutionary invention was created by Alexander Graham Bell. The telephone was invented to send vibrations from one receiver to another electrically (History.com ‘Speech Transmitted by Telephone’ accessed on March 11, 2014), and due to Alexander Graham Bell accidentally discovering that he could hear the sound of a ‘clock spring twanging’ (Marry Bellis, ‘The History of the Telephone’ accessed on March 11, 2014), that was possible. The invention of the telephone permitted new levels of communication, allowed families connect around the world, and improved military systems, but also served negative consequences, such as breached privacy. If two people wanted to have a conversation, they would have to write letters back and forth, but with the telephone they were able to pick up the receiver, dial the number, and be connected in a matter of minutes. Telephones enabled long-distance communication, which allowed families to converse despite their location. Military officials and soldiers were also able to stay in touch through field telephones as well as keep contact with the president. Although telephones were originally placed in general stores or other major city locations and homes/neighborhoods that were wired (Elon.edu ‘World Changes Due to the Telephone’ accessed on April 2, 2014), telephones became commonly used in homes in the early twentieth century when telephones began to connect internationally.
Technology is unavoidable in our modern lifestyle. You wake up, you use technology; you use technology while cooking, while eating, while driving. While you’re lying in bed before you fall asleep, you use technology, technology wakes you up in the morning. Is all the technology around you good for you, or is it harmful to your health? Was our society healthier or safer before all the advancements? So many questions and concerns about all of the technology we crave, but there are very few people who know the answers. Technology affects all parts of human life. It can create jobs, motivate people to get active, and assist people in learning, but this does not balance out that there are dangers that follow the use of technology.
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
The first area where technology and society relates most is communication. People in a society must pass information from one person to another to maintain order. Traditionally, information dissemination was done using inefficient methods such as the messengers and would take long time before it reached to the intended recipient depending on the distance. Technological advancement that resulted in introduction of more efficient means of communication such as mobile phones and computers led to contextualization of the Information and Communications Technology (ICT). This had a direct impact on the society as now information could be disseminated amongst a larger group and in the contemporary wo...
The only means of communication was writing a letter or sending a telegram. The number of people one knew of was limited. At that time, one might not know the person living on the other side of the globe, but they did know who their neighbors were. They talked and interacted with each other and knew what others were going through. They communicated less, but communicated more.
