American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like.

Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard.

Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students’ résumés look better to employers if they list a few extracurricular activities.

Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.

Movies about college life usually have characters that are extreme in some way: super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.

So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you!

Paul Watson is an environmental activist. He is a man who believes that he must do something, not just talk about doing something. Paul believes in protecting endangered animals, and he protects them in controversial ways. Some people think that Watson is a hero and admire him very much. Other people think that he is a criminal.

On July 16th, 1979, Paul Watson and his crew were on his ship, which is called the Sea Shepherd. Watson and the people who work on the Sea Shepherd were hunting on the Atlantic Ocean near Portugal. However, they had a strange prey; instead of hunting for animals, their prey was a ship, the Sierra. The Sea Shepherd found the Sierra, ran into it and sank it. As a result, the Sierra never returned to the sea. The Sea Shepherd, on the other hand, returned to its home in Canada. Paul Watson and his workers thought that they had been successful.

The Sierra had been a whaling ship, which had operated illegally. The captain and crew of the Sierra did not obey any of the international laws that restrict whaling. Instead, they killed as many whales as they could, quickly cut off the meat, and froze it. Later, they sold the whale meat in countries where it is eaten.

Paul Watson tried to persuade the international whaling commission to stop the Sierra. However, the commission did very little, and Paul became impatient. He decided to stop the Sierra and other whaling ships in any way that he could. He offered to pay $25,000 to anyone who sank any illegal whaling ship, and he sank the Sierra. He acted because he believes that the whales must be protected. Still, he acted without the approval of the government; therefore, his actions were controversial.

Paul Watson is not the only environmental activist. Other men and women are also fighting to protect the Earth. Like Watson, they do not always have the approval of their governments, and like Watson, they have become impatient. Yet, because of their concern for the environment, they will act to protect it.

(Adapted from “Eco fighters” by Eric Schwartz, OMNI)

The ocean bottom - a region nearly 2.5 times greater than the total land area of Earth - is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space.

Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation’s Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP’s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor.

The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world.. The Glomar Challenger’s core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger’s voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth.

The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world’s past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change - information that may be used to predict future climates.

It is hard to get any agreement on the precise meaning of the term "social class". In everyday life, people tend to have a different approach to those they consider their equals from which they assume with people they consider higher or lower than themselves in social scale. The criteria we use to 'place' a new acquaintance, however, are a complex mixture of factors. Dress, way of speaking, area of residence in a given city or province, education and manners all play a part.

In ancient civilizations, the Sumerian, for example, which flourished in the lower Euphrates valley from 2000 to 5000 B.C. social differences were based on birth, status or rank, rather than on wealth. Four main classes were recognized. These were the rulers, the priestly administrators, the freemen (such as craftsmen, merchants or farmers) and the slaves.

In Greece, after the sixth-century B.C., there was a growing conflict between the peasants and the aristocrats, and a gradual decrease in the power of the aristocracy when a kind of ‘middle class’ of traders and skilled workers grew up. The population of Athens, for example, was divided into three main classes which were politically and legally distinct. About one-third of the total population was slaves, who did not count politically at all, a fact often forgotten by those who praise Athens as the nursery of democracy. The next main group consisted of resident foreigners, the, ‘metics’ who were freemen, though they too were allowed no share in political life. The third group was the powerful body of ‘citizens”, who were themselves divided into sub-classes.

In the later Middle Ages, however, the development of a money economy and the growth of cities and trade led to the rise of another class, the ‘burghers’ or city merchants and mayors. These were the predecessors of the modern middle classes. Gradually high office and occupation assumed importance in determining social position, as it became more and more possible for a person born to one station in life to move to another. This change affected the towns more than the country areas, where remnants of feudalism lasted much longer.

The National Automobile Show in New York has been one of the top auto shows in the United States since 1900. On November 3 of that year, about 8,000 people looked over the “horseless carriages.” It was the opening day and the first opportunity for the automobile industry to show off its wares to a large crowd; however, the black-tie audience treated the occasion more as a social affair than as a sales extravaganza. It was also on the first day of this show that William McKinley became the first U.S. president to ride in a car.

The automobile was not invented in the United States. That distinction belongs to Germany. Nicolaus Otto built the first practical internal-combustion engine there in 1876. Then, German engineer Karl Benz built what are regarded as the first modern automobiles in the mid-1880s. But the United States pioneered the merchandising of the automobile. The auto show proved to be an effective means of getting the public excited about automotive products.

By happenstance, the number of people at the first New York show equaled the entire car population of the United States at that time. In 1900, 10 million bicycles and an unknown number of horse-drawn carriages provided the prime means of personal transportation. Only about 4,000 cars were assembled in the United States in 1900, and only a quarter of those were gasoline powered. The rest ran on steam or electricity.

After viewing the cars made by forty car makers, the show’s audience favored electric cars because they were quiet. The risk of a boiler explosion turned people away from steamers, and the gasoline-powered cars produced smelly fumes. The Duryea Motor Wagon Company, which launched the American auto industry in 1895, offered a fragrant additive designed to mask the smells of the naphtha that it burned. Many of the 1900 models were cumbersome—the Gasmobile, the Franklin, and the Orient, for example, steered with a tiller like a boat instead of with a steering wheel. None of them was equipped with an automatic starter.

These early model cars were practically handmade and were not very dependable. They were basically toys of the well-to-do. In fact, Woodrow Wilson, then a professor at Princeton University and later President of the United States, predicted that automobiles would cause conflict between the wealthy and the poor. However, among the exhibitors at the 1900 show was a young engineer named Henry Ford. But before the end of the decade, he would revolutionize the automobile industry with his Model T Ford. The Model T, first produced in 1909, featured a standardized design and a streamlined method of production—the assembly line. Its lower costs made it available to the mass market.

Cars at the 1900 show ranged in price from $1,000 to $1,500, or roughly $14,000 to $21,000 in today’s prices. By 1913, the Model T was selling for less than $300, and soon the price would drop even further. “I will build cars for the multitudes,” Ford said, and he kept his promise.

The principle of use and disuse states that those parts of organisms’ bodies that are used grow larger. Those parts that are not tend to wither away. It is an observed fact that when you exercise particular muscles, they grow. Those that are never used diminish. By examining a man’s body, we can tell which muscles he uses and which he does not. We may even be able to guess his profession or his recreation. Enthusiasts of the ‘body-building’ cult make use of the principle of use and disuse to ‘build’ their bodies, almost like a piece of sculpture, into whatever unnatural shape is demanded by fashion in this peculiar minority culture. Muscles are not the only parts of the body that respond to use in this kind of way. Walk barefoot and you acquire harder skin on your soles. It is easy to tell a farmer from a bank teller by looking at their hands alone. The farmer’s hands are horny, hardened by long exposure to rough work. The teller’s hands are relatively soft.

The principle of use and disuse enables animals to become better at the job of surviving in their world, progressively better during their lifetime as a result of living in that world. Humans, through direct exposure to sunlight, or lack of it, develop a skin color which equips them better to survive in the particular local conditions. Too much sunlight is dangerous. Enthusiastic sunbathers with very fair skins are susceptible to skin cancer. Too little sunlight, on the other hand, leads to vitamin-D deficiency. The brown pigment melanin which is synthesized under the influence of sunlight, makes a screen to protect the underlying tissues from the harmful effects of further sunlight. If a suntanned person moves to a less sunny climate, the melanin disappears, and the body is able to benefit from what little sun there is. This can be represented as an instance of the principle of use and disuse: skin goes brown when it is “used’, and fades to white when it is not.

MOBILE PHONES: ARE THEY ABOUT TO TRANSFORM OUR LIVES?

We love them so much that some of us sleep with them under the pillow, yet we are increasingly concerned that we cannot escape their electronic reach. We use them to convey our most intimate secrets, yet we worry that they are a threat to our privacy. We rely on them more than the Internet to cope with modern life, yet many of us don’t believe advertisements saying we need more advanced services. Sweeping aside the doubts that many people feel about the benefits of new third generation phones and fears over the health effects of phone masts, a recent report claims that the long-term effects of new mobile technologies will be entirely positive so long as the public can be convinced to make use of them. Research about users of mobile phones reveals that the mobile has already moved beyond being a mere practical communications tool to become the backbone of modern social life, from love affairs to friendship to work.

The close relationship between user and phone is most pronounced among teenagers, the report says, who regard their mobiles as an expression of their identity. This is partly because mobiles are seen as being beyond the control of parents. But the researchers suggest that another reason may be that mobiles, especially text messaging, were seen as a way of overcoming shyness. The impact of phones, however, has been local rather than global, supporting existing friendship and networks, rather than opening users to a new broader community. Even the language of texting in one area can be incomprehensible to anybody from another area.

Among the most important benefits of using mobile phones, the report claims, will be a vastly improved mobile infrastructure, providing gains throughout the economy, and the provision of a more sophisticated location-based services for users. The report calls on government to put more effort into the delivery of services by mobile phone, with suggestion including public transport and traffic information and doctors’ text messages to remind patients of appointments. There are many possibilities. At a recent trade fair in Sweden, a mobile navigation product was launched. When the user enters a destination, a route is automatically downloaded to their mobile and presented by voices, pictures and maps as they drive. In future, these devices will also be able to plan around congestion and road works in real time. Third generation phones will also allow for remote monitoring of patients by doctors. In Britain, scientists are developing an asthma management solution using mobiles to detect early signs of an attack.

Mobile phones can be used in education. A group of teachers in Britain use third generation phones to provide fast internet service to children who live beyond the reach of terrestrial broadband services and can have no access to online information. ‘As the new generation of mobile technologies takes off, the social potential will vastly increase,’ the report argues.

Ranked as the number one beverage consumed worldwide, tea takes the lead over coffee in both popularity and production with more than 5 million tons of tea produced annually. Although much of this tea is consumed in Asian, European and African countries, the United States drinks its fair share. According to estimates by the Tea Council of the United States, tea is enjoyed by no less than half of the U.S. population on any given day. Black tea or green tea - iced, spiced, or instant - tea drinking has spurred a billion-dollar business with major tea producers in Africa and South America and throughout Asia.

Tea is made from the leaves of an evergreen plant, Camellia sinensis, which grows tall and lush in tropical regions. On tea plantations, the plant is kept trimmed to approximately four feet high and as new buds called flush appear, they are plucked off by hand.  Even in today’s world of modern agricultural machinery, hand harvesting continues to be the preferred method.  Ideally, only the top two leaves and a bud should be pickeb.  This new growth produces the highest quality tea.

After being harvested, tea leaves are laid out on long drying racks, called withering racks, for 18 to 20 hours. Next, depending on the type of tea being produced, the leaves may be crushed or chopped to release flavor, and then fermented under controlled conditions of heat and humidity. For green tea, the whole leaves are often steamed to retain their green color, and the fermentation process is skipped.  Producing black teas requires fermentation during which the tea leaves begin to darken. After fermentation, black tea is dried in vats to produce its rich brown or black color.

No one knows when or how tea became popular, but legend has it that tea as a beverage, was discovered in 2737 B. C.  by Emperor Shen Nung of China when leaves from a Camellia dropped into his drinking water as it was boiling over a fire. As the story goes, Emperor Shen Nung drank the resulting liquid and proclaimed the drink to be most nourishing and refreshing. Though this account cannot be documented, it is thought that tea drinking probably originated in China and spread to other parts of Asia, then to Europe, and ultimately to America colonies around 1650.

With about half the caffeine content as coffee, tea is often chosen by those who want to reduce, but not necessarily eliminate their caffeine intake. Some people find that tea is less acidic than coffee and therefore easier on the stomach. Others have become interested in tea drinking since the National Cancer Institute published its findings on the antioxidant properties of tea. But whether tea is enjoyed for its perceived health benefits, its flavor, or as a social drink, teacups continue to be filled daily with the world’s most popular beverage.

In the last third of the nineteenth century a new housing form was quietly being developed.  In 1869 the Stuyvesant, considered New York’s first apartment house, was built on East Eighteenth Street. The building was financed by the developer Rutherfurd Stuyvesant and designed by Richard Morris Hunt, the first American architect to graduate from the Ecole des Beaux Arts in Paris. Each man had lived in Paris, and each understood the economic and social potential of this Parisian housing form. But the Stuyvesant was at best a limited success. In spite of Hunt’s inviting facade, the living place was awkwardly arranged.  Those who could afford them were quite content to remain in the more sumptuous, single-family homes, leaving the Stuyvesant to young married couple and bachelors.

The fundamental problem with the Stuyvesant and the other early apartment buildings that quickly followed, in the late 1870’s and early 1880’s, was that they were confined to the typical New York building lot. That lot was a rectangular area 25 feet wide by 100 feet deep - a shape perfectly suited for a row house. The lot could also accommodate a rectangular tenement, though it could not yield the square, well-lighted, and logically arranged rooms that great apartment buildings require. But even with the awkward interior configurations of the early apartment buildings, the idea caught on. It met the needs of a large and growing population that wanted something better than tenements but could not afford or did not want row houses.

So while the city’s newly emerging social leadership commissioned their mansions, apartment houses and hotels began to sprout on multiple lots, thus breaking the initial space constraints. In the closing decades of the nineteenth century, large apartment houses began dotting the developed portions of New York City, and by the opening decades of the twentieth century, spacious buildings, such as the Dakota and the Ansonia finally transcended the tight confinement of row house building lots. From there it was only a small step to building luxury apartment houses on the newly created Park Avenue, right next to the fashionable Fifth Avenue shopping area.

They call Jamaica the "Island in the sun" and that is my memory of it. Of sunshine, warmth and abundant fruit that was growing everywhere, and of love. There were two sisters ahead of me in the family, and though of course I didn't know it, there was an exciting talk of emigration, possibly to Canada but more usually to England, the land of opportunity. I guess that plans were already being made when I was born, for a year or so later my Dad left for London. Two years after that my mum went as well and my sisters and I were left in the care of my grandmother.

Emigrating to better yourself was a dream for most Jamaicans, a dream many were determined to fulfill. Families were close and grandmothers were an important part of the family. So, when the mass emigrations began, it seemed perfectly right and natural for them to take over the running of families left behind.

Grandmothers are often strict, but usually also spoil you. She ran the family like a military operation: each of us, no matter how young, had our tasks. Every morning, before we went to school, we all had to take a bucket appropriate to our size and run a relay from the communal tap to the barrels until they are full. My sisters had to sweep the yard before they went to school. My grandmother would give orders to the eldest and these were passed down- as I got older I found this particularly annoying! But I can tell you, no one avoided their duties.

My Dad came over from England to see how we were getting on . He talked to us about the new country, about snow, about the huge city, and we all wanted to know more, to see what it was like. I didn't know it at that time., but he had come to prepare us for the move to England. Six months later my grandmother told me that I was going to join my parents and that she, too, was emigrating.

London was strange and disappointing. There was no gold on the pavements, as the stories in Jaimaica had indicated. The roads were busy, the buildings were grey and dull, with many tall, high-rise blocks. It was totally unlike Jamaica, the houses all small and packed close together. In my grandmother's house I had a big bedroom, here I had to share.

Then came the biggest shock: snow. While flakes came out of the sky and Dad smiled, pointed and said: "That's snow!" I rushed outside, looked up and opened my mouth to let the flakes drop in. The snow settled on my tongue and it was so cold that I cried. My toes lost all feeling. As my shoes and socks got wet and frozen, there came an excruciating pain and I cried with the intensity of it. I didn't know what was happening to me.
