The Evolution of Cell Phones
The cellular telephone, as many other current technological products, started off in the military and eventually made its way to the common consumer as a result of the high demands for such communications technologies. The concept for cellular technology was often thought to be limited to science fiction or futuristic communities. Well the future is now, and computerized technology with the help of transmitters and satellites brings nearly unlimited contact to anyone in the world. The transition of the cell phone from thought to reality was made possible by military technologies and a stress towards communications advancement. Cellular technology evolved from its early development to commercial use sometime in the late seventies as the first cell phones were expensive, appeared bulky, and was fairly inconvenient and inefficient. Currently, cell phones have become efficient, useful, and relatively inexpensive. Into the future, cell phones can only become smaller, more efficient, and globally renowned. Cellular phones are widely used and accepted into modern culture as one of the most popular forms of media communication.
Cellular technology was actually originated in the military two years after the end of the Second World War, in 1947 (about.com). Despite many who believe that the cell phone is a relatively new product on the market, the first usage of any cellular component was very large and strictly for the use and development of the United States military. Actually, the cell phone derives from a two-way radio that uses a mobile phone type of communication of signals. Basically, the first cell phones were simply glorified mobile phones, in essence, that is what all cell phones are. The system uses many stations to divide an area into many cells. As a user moves from cell to cell, calls are transferred from base to base. Around 1968, the Federal Communications Commission, that had haltered the development of cellular broadcasts, now freed up necessary airwaves to allocate the usage of the first cell towers that acted as base stations for phone calls (about.com). This was certainly a start, but these towers only broadcasted a couple miles in radius and there was still no device comparable to today’s cellular technology.
The seventies saw the first working cellular phone components to reach the common market, although bulky, expensive, and inefficient. At a time when disco was lying in its death bed and spandex became popular as a wave of workout videos and aerobics struck the land like a pestilent plague, the demand curve met the supply curve for the commercial development of cellular technology.
1920’s Harlem was a time of contrast and contradiction, on one hand it was a hotbed of crime and vice and on the other it was a time of creativity and rebirth of literature and at this movement’s head was Langston Hughes. Hughes was a torchbearer for the Harlem Renaissance, a literary and musical movement that began in Harlem during the Roaring 20’s that promoted not only African-American culture in the mainstream, but gave African-Americans a sense of identity and pride.

The article begins by stating that the tumor suppressor p53 has great importance in the prevention of cancer growth and expansion. Although cancer is the most spoken about topic and p53’s significance against it, p53 also has a hand in ischemia, neurodegeneration, and ageing. While this tumor suppressor seems to be very busy it also regulates the repair of DNA and death of the cell, just to name a few. The activity of p53 can be seen when binding to the DNA at target sequences for transcription. It was pointed out that the doings of p53 are not designated to the nucleus such as other transcription factors as determined over time. Further mentioned in the introduction is a statement that lists this as the most studied mechanism while also related to the material covered in class is apoptosis. P53 inducts apoptosis in the by intrinsic mitochondria-mediated pathway, also transcriptionally through pro-apoptotic parts of the pathway, and in a transcription–independent way which has been recently been looked further into. As if the roles above were not plentiful enough cytoplasmic p53 is also thought to influence autophagy, movement of vesicles, signal transduction, cell metabolism and possibly stem cell expansion, but all are truly determined. Towards the end of the introductory section the authors state that there are still many mechanisms of cytoplasmic p53’s activation leading to apoptosis that are uncertain as well as some p53 missense mutants that lead to oncogenesis. The authors express that the article mainly will speak about the proper or improper activities performed by p53 on the mechanism in the cytoplasm while also looking for areas where beneficial treatments may be used.
The four poems by Langston Hughes, “Negro,” “Harlem,” “The Negro Speaks of Rivers,” and “Theme for English B” are all powerful poems and moving poems! Taken all together they speak to the very founding of relations of whites and blacks all the way down through history. The speaker in the poem the, “Negro” and also, “The Negro Speaks of Rivers,” tells the tale of freedom and enslavement that his people have endured, and it heralds their wisdom and strength. The poems “Harlem” and “Theme for English B” speaks to the continuous unfair treatment that the blacks have received at the hands of white people throughout the years.
Langston Hughes was probably the most well-known literary force during the Harlem Renaissance. He was one of the first known black artists to stress a need for his contemporaries to embrace the black jazz culture of the 1920s, as well as the cultural roots in Africa and not-so-distant memory of enslavement in the United States. In formal aspects, Hughes was innovative in that other writers of the Harlem Renaissance stuck with existing literary conventions, while Hughes wrote several poems and stories inspired by the improvised, oral traditions of black culture (Baym, 2221). Proud of his cultural identity, but saddened and angry about racial injustice, the content of much of Hughes’ work is filled with conflict between simply doing as one is told as a black member of society and standing up for injustice and being proud of one’s identity. This relates to a common theme in many of Hughes’ poems that dignity is something that has to be fought for by those who are held back by segregation, poverty, and racial bigotry. The poems “Visitors to the Black Belt”, “Note on Commercial Theatre”, “Democracy”, and “Theme for English B” by Hughes all illustrate the theme of staying true to one’s cultural identity and refusing to compromise it despite the constant daily struggle it meant to be black in an Anglo centric society.
Langston Hughes, a renowned poet from the early 1900s, has written numerous poems that have various themes and meanings. Although a lot of his poetry has to do with the struggles of African Americans during the time of slavery or during the early 1900s, Langston Hughes’ themes differ from poem to poem. One theme that appears in multiple poems of his is the theme of race, Langston Hughes uses the theme of race in his poems as a way to challenge the racial barriers that are placed on society. The theme of race is discussed in a plethora of his poems and it is important to examine a few of these poems which include, “I too, sing America”, “Theme for English b”, and “Let America be America Again”, to point out that Hughes tries to implement the sense of hope into African Americans of the time, also he uses race as a way to provide a focus on the oppression of slaves.
Near Death Experiences is a controversial phenomenon that has been debated among researchers, physicians, and the general public. The debate is whether or not what people think they experience is real or if it can to be explained by science. There are twelve characteristics of these experiences that are frequently experienced across the board including out of body experiences which lead to the questions: Does the conscious require the brain, or is it a separate entity that can exist and function on its own? Is there really life after death? Skeptics will answer in the negative and offer many possible explanations, but I can find no good explanation that can account for many of the experiences people have during an NDE.
Langston Hughes, born in February 1st, 1902, grew up in segregated America. His own ancestry was as mixed as that described in the poem. Both his great-grandmothers were enslaved African Americans and both his grandparents were white slave owners. Both of Hughes’ parents were of mixed race descent. Many of his family members were key figures in the elevation of blacks in society, and they impressed upon him the nobility of black people. Hughes had a rootless and often lonely upbringing, moving back and forth between family members’ homes. Hughes was a prominent leader of the Harlem Renaissance and referred to it as the period when “the negro was in vogue”.
Approximately three percent of the population of the U.S has said they have, in fact experienced a near death experience or NDE. While being involved in a near death experience there are reports that consist of involving one or more of the following: having an awareness of being dead, having an out of body experiences, feelings of euphoria, seeing a tunnel of light, and meeting deceased people.
Back in the late 70s and early 80s phones did not have cameras or web browsing or anything like that. They were basically just plastic boxes with wiring inside unlike today’s smartphones with glass touchscreens HD camcorders, video calling, and web capability, but if not for the first cellphone we would not have come so far since then. In 1973 the founder of Motorola Martin Cooper made it easier to call and chat with people and made the worlds first mobile phone. However, it was not approved by the FCC until September 21, 1983, when it became the first commercial portable cellphone. At a cost of $3,995 people thought of this as the future of communication and everyone wanted to get their hands on one though looking back on it now they might have been a little over priced compared to todays modern cellphone prices. We have come a long way since the 70s phones have become more compacted easier to take on the go and today mankind is still coming up with ever newer ways to stay close to ...
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.
When phones became available to the public they were not considered to be mobile in today’s sense of the word. They were available to have installed in an automobile, they were big and bulky, and they needed and consumed a lot of power to use. The phone networks would only support a few simultaneous conversations. Cell phones since then have made vast improvements in their efficiency, abilities, and size. The first handheld mobile phone wasn’t produce until 1973. The origin...
Despite the short amount of time since the introduction of the smartphone, the rapid development of the software and technology has had a tremendous effect on the everyday life in society today. The concept of communicating through a telephone was developed in the 1870s. Devices to transmit speech electrically were designed by Elisha Gray and Alexander Graham Bell, but Bell's design was patented first. On March 10, 1876, Alexander Graham Bell achieved one of his greatest successes in the making of the telephone. This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come (Bellis, 2013b). During the 20th century there were many innovations regarding the telephone. In 1973, the first call from a portable phone was made Martin Cooper, who was a Motorola researcher and executive at the time. Since its inception, the advancement of cell phones has been exponential (Bellis, 2013a). As a result, cell phones have changed how society works in today's world. Many people lack the insight of how cell phones, or in this case, smart phones, affect the people that use them. So the question is, how is the evolution of smart phones impacting our society?
Cell phones represent a type of technology that has been around for more than over fifty years; it has only been recently that many people began to use cell phones as a major part of their everyday life. In the past cell phones were for business people to conduct their business, but in today’s society every one owns a cell phone. Cell phones are interesting, useful and also play a major role in our life’s bringing people closer and keeping in touch with one another. Most people do not know and understand the physics of a cell phone. Cell phones are also known as cellular phone, hand phone, and commonly known as a mobile phone. A cell phone is an electric device that can make and receive calls, over and automatic repeat request (radio link petrol -RLP) used over wireless air interdace.it us a portable telephone that uses and receive phone signals.it also divides that earth into small regional called cells.in the resent estimates there are over 190 million people using mobile phone. One of the primary health concerns is the impact of cell phone radiation, by radio waves by which it operates.
