Cell Phones have demonstrated themselves to be one of the greatest inventions to
mankind. They have come to be an essential part of our lives. Cell Phones are relevant in the
culture of communication as it allows inter connectivity from anywhere in the world, and
immediate access to information. Cell phones impacted my life since middle school because it
never left my pocket. I have the constant ability to communicate from anywhere in the world; I
can easily stay in contact with those most important to me. The communication possibilities are
endless. Cell phones made it possible.(Need More Info.)
Communication has certainly changed a lot over the past one hundred fifty years. Long
before cell phone and telephones were discovered,

The
smoke signals must be used in an area where they will be visible to the receiver and is usually
transmitted on top of a hill or mountain (Smoke Signals). As time progressed, communication
progressed alongside it.
Communication evolved with American scientist, Alexander Graham Bell. History
defines him as the inventor of the telephone. The idea of telephones started when Bell was trying
to modify a method to carry several messages on a single wire. As he was perfecting it, “he heard
the sound of a plucked spring along 60 feet of wire in a Boston electrical shop” (PBS). Upon
having heard the sound, Bell attempted to invent a machine that would transmit sound through
wires by electricity, which was later known as the telephone (Gordon). The telephone gave
people the ability to talk and trade messages with one another from the comfort of their homes.
Also telephones were built in vehicles, which allowed calls to be made and received in the car
using a rotary dial (Wikipedia). Back then people needed the help of operators to connect their
line to their desired destination. It was not until later in the future that telephones
To begin with, the Invention that Alexander Graham Bell is most remembered for is the telephone. I will explain the idea, how it works, and the story behind it. First, the harmonic telephone was just an idea till about the year 1874 when Mr. Bell started work on the phone to send multiple telegraph messages at one time. This device would take a telegraph line to transfer the human voice from one place to another. For this job he hired a man named Thomas A. Watson, electrical designer. Second, the way this machine works is that the transmitter was in one room with metal strings attached to the device. Which looked like a cone connected to metal strings. Those strings would stretch out of the room to a different room. In the other room the receiver was there this looked like an 8 ounce cup of water. These two things were the transmitter and receiver of the first telephone from 1876. Thirdly, the story behind the telephone made it even more special that Mr. Bell actually made the telephone in Canada and was never an American citizen yet got the protection of invention by the United States of America. This story all started when Alexander was in his room working on the phone and his partner...
The world’s first mobile phone call was made on April 3, 1973, when Martin Cooper, a senior engineer at Motorola, called a rival telecommunications company and informed them he was speaking via a mobile phone. The phone Cooper used, if you could call it that, weighed a staggering 1.1kg and measured in at 228.6x127x44.4mm. With this prototype device, you got 30 minutes of talk-time and it took around 10 hours to charge.”(knowyourmobile). Back then cell phones weren’t as flashy but everyone was just as excited for them as they are now. “Many of the early cell phones were considered to be “car phones,” as they were too large and cumbersome to carry around in a pocket or purse. However, in 1983, the Motorola DynaTAC 8000x arrived on the market. Though huge by today’s standards, it was considered the first truly mobile phone because it was small enough to carry.”(artinstitutes).
What is a cell phone? When did the cell phone come out? Cell phones are electronic devices used for communicating. Engineer Martin Cooper was the first individual who made the first public cell phone in 1973 (Browning). Later on, the cell phone became the most important tool for our daily life in the modern world. Today society is a cell phone-controlled world, to some degree. Even though it is true that cell phones bring countless conveniences to people, the use of cell phones should be restricted. Despite their advantages as mapping and communication tools, they can cause accidents when used while driving, restrict driver’s attention which can cause safety concerns, and even lead to health problems.
Automobiles were beginning to appear on the dirt roads, telephone service was starting to make
Cell phones have made a big impact on the world, for example, people are using them daily, and they have influenced science, politics, and many more fields.
..., extensive researching and experimenting lead to what no one else could seem to figure out. While facing many setbacks and failed experiments over the two years, they still managed to successfully transmit human speech simultaneously on one wire. With great triumph with the telephone, Bell began to showcase his invention across Massachusetts and conventions, colleges, and meetings. He became a well respected, known inventor (Bell Invents the Telephone). People were amazed at Bell’s invention and were astonished when they were able to instantly hear someone talking miles away. Bell’s invention would create the basis f communication and allow other inventors to make advancements to the telephone for future generations. Bell used his fascination and knowledge with human speech to successfully invent the telephone, which transformed the lives of everyone in the world.
Christmas time, when the weather changes, family visits, memories are made and Christmas list are filled, at least that is how it used to be. Each decade brings about a new generation that will repeat trends, transform and also innovative new ways and uses of the basics. Children often make request to love ones during the holidays, ranging from the must have toy to the latest fashion trends. While adults have outgrown list, wishes are never few as desires for lavish vacations, cars or visit from distant family or friends. In life there are wants and needs which create a desire and keep us pushing, connecting and evolving.
At a young age, Bell started to recreate the sound of the human voice, “At the age of 16, he built a talking machine from rubber and strips of tin. He could make the device’s tin strips vibrate and produce bl...
The cylinder phonograph proved to be successful, but the problem with the machine was that the tin foil only allowed a few uses. With the help of another great inventor, new advances could be made to improve this invention. The inventor of the telephone, Alexander Graham Bell, had set up a laboratory for his cousin, Chichester Bell and Charles Tainter. Bell a...

As long as I’ve lived there has always been some form of a mobile phone. Before the invention of cell phones I imagine that the world was a lot more mystery in the world. Now we can find all information on our phones. We have phone addicts who have to have their phone ...
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.
-Due to the era of technology, people can communicate virtually no matter how far they are located for instance using emails the way I had done.
The definition of a cell phone is a portable telephone that uses wireless cellular energy to send or receive messages or voice calls. The first people who were able to correctly demonstrate the usage of the first cell phone were two men by the names of John F. Mitchell and Martin Cooper. It had been named “The Jitterbug” . It looked like a big house phone. It also weighed about 2.3 pounds (or 1 kg) Only thing was, it had finally been able to be used in a different place than home. In the year 1983, the next cell phone that had become available was the DynaTac 8000x. It also looked like a big house phone, but that was the first phone to be publicly released.
Alexander’s most popular and most well-known invention was the telephone. It was an upgrade from form of communication at the time, the telegraph, which was a clicking machine that had different patterns for each ladder of the alphabet. “The telephone was able send telegraph transmissions that could be sent on the same wire if they were transmitted on different harmonic frequencies.”(Alexander Graham Bell Bio) The telephone had an end where you speak into it and the other end played the noises from the other telephone. “He was the first to realize electrical currents could exactly duplicate sound waves transmitting multiple sounds by vibrating the air in a series of frequencies” (Alexander Graham Bell) Bell believed his invention of the photophone was even greater than the telephone. The photophone was a device that enabled sound to be transmitted on a beam of light. He developed it using a sensitive selenium crystal and a mirror that would vibrate in respond to sound. He was able to successfully send a photophone message over 200 yards from one building to another. He used the help of his assistant Charles Sumner Tainter on this invention.
