Disadvantages of science Essay Example for Free

Disadvantages of science Essay How Science and Technology Affects Humans Life Science and technology are two things related to each other. Science is a systematic knowledge base, where a series of steps is followed in order to reliably predict the type of outcome. It is all about theories and focused on analysis. Science is the key by which man go anywhere at any time in the space. It has brought about several outstanding advantages to mankind. Technology, on the other hand, is more of an applied science. It is where tools and knowledge are used for the study of a particular science. It is all about process. What is life without science and technology? Nowadays, people can’t imagine their lives without technology. Anywhere they go and whatever they do, there are many things related to science. These are humans inventions and innovations or various technologies surround them that provide their needs. Even in their daily activities or simple tasks, they are already using those technologies. Refrigerators, microwaves, televisions, cellular phones, laptops, digital cameras, cars, computers and lights are some technologies that human uses in their daily lives. These technologies really provide them many advantages. It is easy to think about the advantages however, for your information technology has also disadvantages. Science and Technology helps human beings make their lives easier in such a way that it helps them in every sector. Like in transportation, through cars, airplanes or trains, they can travel faster to their desired places. From inventions and innovations of great minds, robots and machines are made to help people make lesser mistakes. Because of technology, man can save his time, efforts and give him a quality to his works. Moreover, technology increases production. People can create multiple materials in a short period of time because of modern machines. Most of all, one of the most important advantages of technology is through the field of medical science or human health. Because of the inventions of technology for surgical operations and discoveries of many medicines, human’s life span will be lengthened and will save innocent lives. Science and Technology also changed human’s way of communicating. From telephones to cellular phones, then came the computers and Internets which gave them information. Through these, now they can do video conferences to their love ones at abroad or chatting their friends. Satellite communication is another important dimension of technology. Satellite TV s and satellite radios have eased the broadcasting of events across the globe. Computers can store, organize and manage huge amounts of data. They can process large amounts of information. Computers have given rise to the software industry, one of the most progressive industries of the world. Gadgets can give entertainment not only to teenagers but to everyone. In addition technology also gives assurance or for emergency use. On the other hand, with the advancement in the field of latest technology, people face many disadvantages out of the benefit of modern technology. It can harm our environment. New transportation technology causes pollution by the smoke or gas from factories and cars. Most people lost their job because companies took up automatic machines to improve their production with accuracy. Yet, the answers or discoveries that technology gave may not be always correct. These machines look inexpensive and its good to use but once there are technical problems occur in machines, it took much time to fix it and also it can be more expensive. There are also side effects of technology in our health. This can cause growth of eye disease, increase of body weight and can cause cancer because of radiation of specific technology. Science and Technology can cause peoples communication poor. According to Lauren Nelson, when communicating face to face, nonverbal behaviors provide context clues for the words we use. Unfortunately, the Wall Street Journal found that technologies like email, texting and instant messaging remove these important context clues, and can lead to misunderstandings. Sarcasm and jokes without nonverbal context cues can cause frustration. Though smiley faces with different expressions called emoticons are sometimes used to substitute traditional nonverbal cues, they fall far short of what face-to-face communication can provide. He also states that as more students buy cell phones, iPods, and gaming systems, technologys impact on effective communication is becoming more pronounced. As the District Chronicles reports, teachers attempting to convey messages about lessons and textbooks find students are texting, playing, or listening to music. Not only does this mitigate the teachers ability to communicate lessons, but it hurts future communicative interaction between the teacher and student because of the lack of respect it conveys. The youth has also been very much addicted to gadgets that they get to spend too much time with it and creates their own world. Technology can make people lazy. Many people are already dependent and embrace this technology. Like students playing computer games instead of going to school or study. Technology also brings us privacy issues. From cell phone signal interceptions to email hacking, people are now worried about their once private information becoming public knowledge and making profit out of video scandals. Advanced technology has also created thousands of cases of cyber crimes, cheating and fraud. And most of all because of the new technology, the world may be facing terrorists threat and all of us are afraid of nuclear war. If people of the world use these inventions and innovations in a right way, we are all going to be benefited out of these but if the motive of a human being is not positive, surely they will face the technologys disadvantages.

Western Movies Since 1960 Essay -- essays research papers fc

A NOT-SO-ACCURATE prophet once wrote, "As recently as 1972, there were a tremendous number of quality Westerns being made . . . and since there seems to be a ten-year cycle in Western movie making, I'd say we'll see more in about 1982." 1 In 1982 only two Westerns were released, and neither was exactly a major success. Barbarosa, starring Willie Nelson, drew some respectable reviews–and some very damaging ones–but nobody went to see the film. The Ballad of Gregorio Cortez appeared first on PBS television, then later went into general release. Today the Western seems to be deader than the California Med-fly. Critics and aficionados of the form can only hear, as with Arnold's sea of faith, its long receding roar. Everything except fluoride in the water has been blamed for the death of the Western. Even critics themselves have come under attack of late. Stephen Tatum, writing in 1983, called critics such as Brian Garfield and Don Graham "shootists," indicting them for a variety of sins. They are said to hold a "fundamentalist," transcendent conception of the Western. They are "redeemer" critics who wish to stop the clock, deny history, and halt the inevitable evolution of genres. Not only that, Garfield and Graham are moreover accused of being "authoritarian" and suspiciously close to the "moral majority" position.' It seems quite possible, however, that the roots of the Western's decline lie deeper than in the likes and animadversions of benighted critics. The Western has lost its audience. An entire generation of moviegoers has seen one big-screen Western in their lives, and that, sadly, is Blazing Saddles (1974). For this generation, who as children were glutted with television Westerns, such a legacy makes the Western an impossible form. Blazing Saddles is the final debunking of a long tradition and exposes the Western's moral preachiness, its presumed insensitivity to blacks, reds, women, and other minorities, its good-guy-bad-guy schematic oppositions. Blazing Saddles took the Western into the terrain of the scatological, and from that defamation, nothing could be regained for an entire generation. By the early 1980s, the Western seemed hopelessly irrelevant to the largest share of the moviegoing audience–the teen market.

Building Blocks of Life Essay

Part 1: Mitosis and Meiosis Short-Answer Response Use Ch. 5 of BioInquiry and the â€Å"Comparing Mitosis and Meiosis† video as resources for Part 1 of this assignment. Write 75- to 100-word answers to the following questions. Why are the process of mitosis and meiosis both important to a living organism? Both mitosis and meiosis processes are extremely important because they are the division of chromosomes and without this division reproduction would not occur. Cell division plays an important role in the life cycle of a cell allowing the cell to grow, develop and then reproduce. If these processes did not occur then the cells would eventually die out and without the ability to be replaced by new cells then the host would die as well. When would an organism need to undergo the process of mitosis? Meiosis? An organism would need to undergo the process of mitosis in order to repair damaged cells or to start a new cell life cycle through cellular division. All cells need to be replaced on the regular basic within a living organism the cells divide and create new cells. An organism would need to undergo the process of meiosis when it needs to produce cells that are designated for sexual reproduction, such as egg or sperm cells within humans What would happen if meiosis did not occur? If meiosis did not occur then haploid cells would not be made resulting in the cell being unable to reproduce. Meiosis I reduces the number of chromosomes by half so that when fertilization occurs the number of  chromosomes would be reestablished. During meiosis II the daughter cell is a unique variation of its parent cell while still only having one pair of chromosomes. Part 2: Photosynthesis and Cellular Respiration Matrix Complete the matrix. Use the following questions to aid in completion: What is the purpose of this pathway? Reactants: What does this reaction need to proceed? Products: What is produced because of the reaction? The role of ATP: Does it supply energy or store energy?

Analysis Of The Article Problematizing Carceral Tours, By...

Empirical research on prison systems is important in ensuring an accurate understanding of the success of rehabilitation. Prison tours should not occur because the tours are scripted and give an inaccurate depiction of prison life as well they dehumanize the inmates. In the article problematizing carceral tours by Justin Pichà © and Kevin Walby, the ways in which carceral tours are not beneficial for all members is highlighted. They state that some of the tours are scripted, in the hopes of setting a good impression for the public. Tour officials spend a significant amount of time preparing for their tours and deciding on the impression they wish to create. Tour organizers must dress to impress, carefully consider timing of tours, and the location of the tours within the penitentiary. This is to ensure the prisoners and guards are not distracted and to assure their schedules are not interrupted. Institutional operations are put before the needs of the tours. In addition, prison tours are seen as dignity rupturing, which creates dishonourable tours. On the other hand, in response to the previous article, the article written by the Howard Journal of Criminal Justice titled In Praise of the Carceral Tour: Learning from the Grendon Experience by David Wilson, Roy Spina and Joyce E. Canaan. Which outlines the ways in which tours are beneficial for all members. The students speak about how their preconceived perceptions of prison were disproved during their penal institution
