As I laid my curious, four year-old eyes upon a mysterious button, I could hear it calling to me. “Press me. Come on. Do it.” Unable to resist the temptation, I pressed it to find a little compartment slide out of the side of my walkie talkie with a tiny man inside. He smiled, waved, and then slid back into my toy in order to operate it. Completely taken by surprise, I was unable to react. Immediately afterwards, I scrambled to press the button again. I had so many questions to ask the strange man. How does he live in my walkie talkie? Does he ever come out? Are there 2-inch tall men in each of my toys? Before I could find the button again, I woke up. Remembering the dream vividly, I was struck with curiosity. I always assumed that my walkie talkie carried my voice to its twin just because it was in its nature to do so, but after I had that dream, I started to wonder about what really made my toys and other devices function. …show more content…
I found six screws on the back panel and, with the help of my dad and a screwdriver, I opened it up to find, not a little man, but a circuit board. “How does a green rectangle control a walkie talkie?” This raised more questions than answers. I later learned that I was holding a circuit board in my hand and that there were more parts inside the walkie talkie than I had uncovered, but my four year-old self was incredibly confused. I sat on the sofa for hours staring at the device, tracing copper pathways and poking at it to see if it would
Radio waves were first discovered in 1887, but radio itself was initially invented by Italian Guglielmo Marconi in 1895 (1). His biggest mentioned success was in 1901, when he managed to broadcast the letter “S” across the Atlantic Ocean (1). However, he focused primarily on point-to-point transmissions, not large scale broadcasts from one point (F). As such, three American inventors - Lee De Forest, Edwin Howard Armstrong, and David Sarnoff - took credit for making radio as it is today a success (F). De Forest was born and raised in Alabama and he thought of everything in terms of patents and eventually held more than 300, but many claimed that he simply stole the inventions of others (2). In 1900, he patented a device to enhance weak signals and in 1902, he formed the De Forest Wireless Telegraph Company (1). In the same year. Reginald Fessenden, a Canadian, invented the “electrolytic detector”, which later became the spade detector that brought De Forest so much fame (F). In 1904, John Fleming invented the oscillation valve, which later became De Forest’s audion, and De Forest won the gold medal at the St. Louis World’s Fair for his “spade detector” (F). De Forest gained quite a bit of fame by broadcasting music live from the Eiffel Tower and from the Metropolitan Opera; however, many believed that this was a scam and that he had actually had the device broadcasting the signal only a few blocks away (F). In 1906, he envisioned bringing music and voices to all American households, but as it turns out Canadian inventor Fessenden had already broadcasted a Christmas greeting and music to the crew of a ship off the coast of Canada on Christmas Eve a year earlier (F). In 1912, Armstrong became prominent by inventing regeneration, wh...
Ever since time began, Humans have circled the Earth searching for riches, land and to unravel the mysteries of the universe. When Humans see something they desire, they do whatever it takes, by sword, persuasion, or negotiation to achieve it. Moreover every moment of mankind 's existence is spent trying to become stronger than their neighbor and even nature itself. Since its dawning, mankind has always been a war ragging race. Moreover, the smarter this race thinks they get, the more they take for granted of what the beautiful creator has given them. Along with that, every human lives a technology filled life, it is as if the entire race has been disconnected from the natural giving planet around them. Nevertheless, if one mistake stands above all, it is their lack of knowledge of their own history. No matter how many times mankind makes a fatal mistake they never learn from it and within a decade they repeat the process again. Walter Clark 's "the Portable Phonograph" perfectly shows how humans take
Has anyone ever wondered how radio communications changed society during the 1930’s? According to the research done by the Education Foundation, many people believe that the most important development in the radio at that time was entertainment; this is entirely false. In fact, radio communications not only made an impact in the way people received their news, but also brought together a nation that got out of a brutal depression. Together, the nations as one made radio communications the commanding form of media in the 1930’s. As stations and businesses were beginning to establish themselves, companies from across the nation were taking notice in the department of advertisement. This new realm ignited a spark for the nation’s new economy which later boomed and gave rise to an economically and socially powerful country.
Hidden Truths in The Enormous Radio John Cheever’s "The Enormous Radio" represents the enormous amount of hidden truths in American society in the 1940s. The problems with society during this time were hidden behind a facade of goodness; however, this false innocence becomes visible through the radio owned by the Westcotts. The radio causes the Westcotts to evolve from an innocent, naive pair who believe that everything they see is real, into individuals who realize that appearances are deceiving. Cheever develops the motif of innocence by details like Irene’s "wide, fine forehead upon which nothing at all had been written" (817). However, it also includes the fact that Irene "wore a coat of patch skins dyed to resemble mink" (817).
"The Enormous Radio" by John Cheever begins with Jim and Irene Westcott who are an average American couple with an average American family. Cheever describes them as middle-aged, having two young children, a pleasant home, and a sufficient income. On the surface they seem to have a perfect life, but underneath this is not the case. In the course of the story, Irene’s imperfections are revealed by a hideous radio. The radio was bought to give the Westcott’s listening pleasure, but then they discover it can hear all the neighbors’ conversations. Irene becomes so obsessed with eavesdropping on her neighbors’ conversations, that it blinds her from her own problems.
Even though the cell phone ownership among teens have been stable since 2011, the ownership of smart phone has grown significantly from 23% in 2011 to 37% in 2012. Figure 4 from a study on teens and technology, which was done in 2013 by the Berkman center for internet and society at Harvard University, shows the percentages of teens’ cell phones and smartphones ownership.
We often take for granted items that we use in our everyday lives. When I was a child, I never once stopped to think about the radio. It had simply always been there. I would record songs on a cassette tape off the radio. I would call into radio stations to wish my friends a ‘Happy Birthday’ on the air. When I started driving the radio was a constant presence. Even today on my daily commute to work I turn the radio on and sing along, not once wondering where it had come from. Empire of the Air: The Men Who Made Radio was the documentary I never knew that I needed. It was interesting to learn not only how the radio we take for granted today came to be, but also the intense drama and fighting that the men who made radio went through.
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.
I have created an instrument that has the power to change the world of sound forever. While trying to improve the telegraph I have created a machine capable of recording sound and playing it back. I have tested the prototype extensively and I have incredible confidence that the machine will be a necessity for many people and it has the possibility of leading to more incredible creations. In order to produce this amazing machine, I am asking for a loan of $15,000.
Cell phones have become a part of mainstream culture. Recently they have become more affordable and accomplish much more than making and receiving calls. Along with the growing popularity there is also growing concerns about safety and health. In this paper we will address cell phone history and how they have evolved. We will discuss health concerns such as tumors and talking while driving. Finally, we will talk about all of the technology that cell phones can accomplish such as receiving Email and buying stocks.
Many inventions have impacted the world throughout history but in my opinion one of the most impactful one’s was the invention of the radio . This invention provided society with many things which include entertainment, communication, and easier access to information. Radio is still a central part of the society today but just like any other invention radio has an interesting history of how it progressed through time.
The year is 2014, the markets are changing constantly, and they always have to meet the needs of new consumers as well as old consumers. Mobile telephones have been in the retail and wholesale business for quite some time, and are only evolving from here on out. There are things that these cell phones can bring us that are major benefits in our everyday lives. Cell phones bring us maps, radios, address books, and even flashlights now. Cell phones have taken shape from a huge portable device to a more convenient thin device that can fit in your pocket. With time in any consumer market, the consumer adapts to the technology that makes their life easier. The constant innovation of cell phones has led us to smart phones, and these smart phones are capable of putting certain businesses out of the market. Businesses that engineered PDAs in the past were met with challenges because smart phones are able to match their productivity. Land lines have become useless since everyone can afford a mobile device now. Listening to music has also switched from a traditional CD Player/MP3 Player to an everyday smart phone.
With Television being the dominate medium, and Computers taking second position, where does that leave Radio? 95 years ago radio was the second language of mass media and it has been around since, making it a great survivor medium. Radio has changed the way we communicate. The first broadcast was in 1916 out of the garage of Frank Conrad who moved his station to Westinghouse factory where he relaunched the station as KDKA on November 2, 19201. Radio has since branched out with each branch growing a new form of media to create a world of new Radio sub-categories. Radio has become a medium of entertainment, education and information giving listeners a form of imagination, relaxation and escape from our daily lives.
The house phone started to ring. “We have a house phone?” I questioned myself rubbing my eyes giving off a weary sigh. When did I fall asleep? I headed downstairs and it stopped. Again it rang and I guessed it was on the bottom shelf hence lack of usage. Pulling off the dusty cloth I grasped the telephone and answered.
What invention has impacted you the most? The invention of the cell phone has impacted me in many ways. It has made a lot of things more convenient, changed the way I interact with people, and changed the way I connect to the world.
