whether we realize it or not, tv plays a very important part in our lives. it's the main source of information and a cheap form of entertainment for millions of people. it's the window on the world which gives us an opportunity to "travel" all over the world, to "meet" different people and learn about their customs and traditions. it has the power to educate and broaden our minds. it helps us to relax after a hard day's work and escape from reality as there's always a great variety of programmes on tv: news and sports programmes, talk shows and tv games, documentaries and feature films, concerts and theatre but at the same tame we become more and more addicted to the tv.
today it’s not a secret that there is at least one tv set in 98% of american households, and many have two or three. and of course, television influences people’s mental picture of the world, especially their perceptions of distant events. this is particularly true for younger viewers, who rely heavily on television for their understanding of the world beyond their neighborhood. as the predominant mass medium, television is greatly criticized for failing to provide a complete, unbiased picture of reality. some individuals and citizens' groups have expressed concern about the level of violence in television programmes, particularly in action-adventure series and cartoons. they argue that viewers, especially children, may learn to see violence as the only way to resolve conflicts. and this is partially confirmed by researches.
some argue that parents are responsible for supervising their children's tv viewing. but how? children are often watching television when their parents are either not in the room or even at home. many parents think they can use the help in monitoring what their children see. the reality is that one in four families is headed by a single parent, and in two-thirds of two-parent families, both parents are working. furthermore, nearly 50 percent of children between the ages of 6 and 17 have their own tv sets in their bedrooms. on the one hand tv became an indication of both material wealth and the individual freedom (the us), on the other hand it became a trap for children. not noticing how they are becoming “couch potatoes” and tv maniacs. children are reading less today, they just do not know how wonderful and interesting it is to read. instead they spend hours in front of the "box" watching whatever's on — from second-rate mexican soap operas to silly commercials. the situation is that they rather watch a baseball game on tv than go play softball in the park with friends or even go to a movie. the irony is that although american television seems to promote images of slender, physically fit people, the more people watch tv, the less likely they are to exercise. some people spend much of their free time lying on the couch watching tv and eating junk food. as a result, eating disorders such as anorexia and bulimia are now common among young women. many teenage girls have become insecure about their bodies and obsessed with losing weight.
the trick is to learn to control television and use it intelligently. the ideal is to turn on the tv-set only when there's a really interesting programme. if you don't like a certain programme, why watch it? why should you waste your free time on it if you can enjoy yourself in a more proper way? from all these we come to the conclusion that the impact of tv is great and we should not watch one and all but filter the useful information so that television would be not a dead but helpful hand.
Sir Isaac Newton is an English scientist and mathematician. He was born in 1642, on the 25th of December in the little village of Woolsthorpe in England. His father was a wealthy farmer but he had died before Isaac was born.
Newton published his discoveries in two books which contain his three laws of motion and the universal gravitation law. The scientist used these laws to predict the motion of the planets around the Sun, the stars and comets motion. Isaac Newton studied optics and developed the theory of colour: he discovered that a prism could decompose white light into a multicoloured spectrum. He was also the constructor of the first practical reflecting telescope in the world. As for mathematics he and Leibniz developed the fundamental theorem of infinitesimal calculus.
Moreover Isaac Newton devoted his time to studying theology and practicing alchemical experiments. It is known that he published some of his theological researches. He made an attempt to predict the end of the world and he estimated it would happen after the year of 2060.
Newton studied at Trinity College in Cambridge University. His incredible aptitude was recognized early. It was there that he discovered the generalized binomial theorem. Then he moved to London in 1969 where he lived until his death in 1727. The scientist was also a member of the Parliament of England. Newton died in his sleep at the age of 84 and was buried in Westminster Abbey. He was never married and died intestate.
Isaac Newton is considered to be the most influential scientist in the history of mankind. His discoveries on physics, astronomy and mathematics provided a basis for modern science and his ideas changed our world.
Перевод
Сэр Исаак Ньютон – английский ученый и математик. Он родился в 1642 году, 25 декабря в маленькой деревушке Вулсторп в Англии. Его отец был зажиточным фермером, однако он умер до того, как родился Исаак.
Ньютон опубликовал свои открытия в двух книгах, содержащих три закона механики и закон всемирного тяготения. Ученый применил эти законы для вычисления движения планет вокруг солнца, движения звезд и комет. Исаак Ньютон изучал оптику и разработал теорию цвета: он обнаружил, что призма разлагать луч белого света на многоцветный спектр. Он также стал создателем первого практического зеркального телескопа в мире. Что касается математики, он и Лейбниц разработали фундаментальную теорему бесконечно малых величин.
Кроме того, Исаак Ньютон посвящал свое время изучению теологии и проведению алхимических экспериментов. Известно, что он опубликовал некоторые из своих теологических исследований. Он предпринял попытку предсказать конец света и рассчитал, что это произойдет после 2060 года.
Ньютон учился в Тринити Колледж в Университете Кэмбридж. Его невероятные были рано замечены. Именно там он открыл универсальную теорему бинома. Затем он переехал в Лондон в 1969 году, где прожил вплоть до своей смерти в 1727 году. Ученый также являлся членом английского Парламента. Ньютон скончался во сне в возрасте 84 лет и был похоронен в Вестминстерском аббатстве. Он никогда не был женат и умер без завещания.
Исаак Ньютон считается наиболее значимым ученым в истории человечества. Его открытия в области физики, астрономии и математики сформировали основу для современной науки, а его идеи изменили наш мир.
