     Dogs are extremely useful as companions for blind people. When a dog has been properly trained, he will always lead his blind master in the right direction and keep him out of danger. For example, seeing-eye dogs learn never to cross a busy road when cars are coming, even if their masters command them to do so.
     Horses are also able to learn many things too. Horses that are used for guard or police duty must learn never to be frightened of noises, traffic, and other disturbance. Racing horses are able to run much faster than other horses, but they are also quite high strung. Therefore, it is necessary for people who train them to be very patient and understanding.
     Pigeons have a natural instinct to return home, even if they are very far away and the trip is hard or dangerous. Men utilize this homing instinct to send messages on small pieces of paper that are fastened to the pigeon’s back or legs. In wartime, pigeons have been known to fly as fast as 75 miles an hour and to cover distances of 500 to 600 miles. These homing pigeons begin their training when they are about four weeks old. After a few weeks they can begin flying and carrying messages. If all goes well, their flying career lasts about four years.
     Animals can learn to do many things that, while not necessarily useful, are very amusing to watch. In circuses, animals are taught to do the tricks that are most compatible with their physical and temperamental make-up. Lions and tigers can be taught to spring gracefully when told to do so, or to stay in place on command. Elephants learn to walk in line, to stand on their hind legs, to lie on their sides, and to stand on their head. They can also learn to dance.

     In the laboratories where astronauts are trained for their journeys, they are subjected to conditions that resemble those of flight. It takes time for them to prepare for the great changes that occur in space. When the spaceship leaves the earth at tremendous speed, the astronauts feel as if they are being crushed against the spaceship floor. Later, when they leave the zone of the earth's gravitation, they are unable to stay in one place. Simple actions, such as eating and drinking, become very difficult to perform. You may get an inkling of what the astronauts have to deal with if you try to drink a glass of water while standing on your head or while just lying down.
     The beginnings of man's conquest of space took place in 1958, seven years before Leonov's trip. The first successful launching of "Sputnik" demonstrated that it was indeed possible to send objects far enough out of range of earth's gravity so that they would not fall back to earth. Rather, such objects could be forced to revolve about the earth, just as the moon does. However, while the moon is so far from earth that it takes it a month to revolve around the earth, man-made satellites, which are closer to earth, can make a complete revolution in a few hours.
     It was three years after the first satellite launching that a spaceship containing a man made a successful flight. The flight lasted less than two hours, but it pointed the way to future developments.
     Other planets are so far away that spaceships must attain tremendous speeds to reach them in a reasonable time. If spaceships were launched from space or from the moon, the absence of weight would permit the ships to be launched with great speed at reduced pressures. A relatively small explosion would be enough to send a ship off at a very fast rate. And since there is no atmosphere in space as there is on earth, the spaceship would meet with no resistance.

       About three hundred years ago, there were approximately half a billion people in the world. In the two centuries that followed the population doubled, and, by 1850, there were more than a billion people in the world. It took only 75 years for the figure to double once more, so that now the population figure stands at approximately six and one half billion. Each day the population of the world increases by about 150,000. 

       In former centuries the population grew slowly. Famines, wars, and epidemics, such as the plague and cholera, killed many people. Today, although the birth rate has not changed significantly, the death rate has been lowered considerably by various kinds of progress.
       Machinery has made it possible to produce more and more food in vast areas, such as the plains of America and Russia. Crops have increased almost everywhere and people are growing more and more food. New forms of food preservation have also been developed so that food need not be eaten as soon as it has grown. Meat, fish, fruit and vegetables can be dried, tinned or frozen, then stored for later use.
       Improvement in communications and transportation has made it possible to send more food from the place where it is produced to other places where it is needed. This has helped reduce the number of famines.
       Generally speaking, people live in conditions of greater security. Practices such as the slave trade, which caused many useless deaths, have been stopped.
       Progress in medicine and hygiene has made it possible for people to live longer. People in Europe and North America live, on the average, twice as long as they did a hundred years ago. In other countries, too, people generally live much longer than they once did. Babies, especially, have a far better chance of growing up because of increased protection against infant disease. However, all countries do not benefit to the same degree from this program in medicine and hygiene.

         Today, there’s scarcely an aspect of our life that isn’t being upended by the torrent of information available on the hundreds of millions of sites crowding the Internet, not to mention its ability to keep us in constant touch with each other via electronic mail. “If the automobile and aerospace technology had exploded at the same pace as computer and information technology,” says Microsoft, “a new car would cost about $2 and go 600 miles on a thimbleful of gas. And you could buy a Boeing 747 for the cost of a pizza.”
          Probably the biggest payoff, however, is the billions of dollars the Internet is saving companies in producing goods and serving for the needs of their customers. Nothing like it has been seen since the beginning of the Industrial Revolution, when power-driven machines began producing more in a day than men could turn out in nearly a year. “We view the growth of the Internet and e-commerce as a global megatrend,” says Merrill Lynch, “along the lines of printing press, the telephone, the computer, and electricity.”
          You would be hard pressed to name something that isn’t available on the Internet Consider: books, health care, movie tickets, construction materials, baby clothes, stocks, cattle feed, music, electronics, antiques, tools, real estate, toys, autographs of famous people, wine and airline tickets. And even after you’ve moved on to your final resting place, there’s no reason those you love can’t keep in touch. A company called FinalThoughta. com offers a place for you to store “afterlife e-mails” you can send to Heaven with the help of a “guardian angel”.
          Kids today are so computer savvy that it virtually ensures the United States will remain the unchallenged leader in cyberspace for the foreseeable future. Nearly all children in families with incomes of more than $75,000 a year have home computers, according to a study by the David and Lucile Packard Foundation. Youngsters from ages 2 to 17 at all income levels have computers, with 52% of those connected to the Internet.

     The over-60 population growing faster than any other age group. Between 1950 and 2050 it is expected to increase from 200 million to 2 billion. As the number of older persons increases, so will the need to ensure their social inclusion, based on an income from decent work or retirement and a chance to participate in community life through employment, volunteer work or other activities. Decent work treats men and women equally, without discrimination or harassment. Finally, decent work provides social security and is carried out in conditions of freedom and human dignity.
     In most developing countries retirement is a luxury few older people can afford. Even in developed countries some hard working people will not have enough to live on retirement. Many women—paid less than men, working more at home than men, and working more informally than men—may not be ready or able to rest at 65.
     By tradition, at least in developed countries, there is a change in roles as one moves from active middle years into “gentle” and “enjoyable” retirement. This change in roles has been viewed by the public, by government and by business, as a transition from a productive time of life to one that is unproductive and dependent. But today more than ever, this is not true. Most older people do not withdraw from society. Instead, they continue to contribute to their households, to their descendants and to their communities, although their contribution may not be paid employment.

     Pollution is a “dirty” word. To pollute means to contaminate —to spoil something by introducing impurities, which make it unfit or unclean to use. Pollution comes in many forms. We see it, smell it, taste it, drink it, and stumble through it. We literally live in and breathe pollution, and, not surprisingly, it is beginning to threaten our health, our happiness, and our very civilization.
     Once we thought of pollution as meaning simply smog — the choking, stinging, dirty air that hovers over cities. But air pollution, while it is still the most dangerous, is only one type of contamination among several which attack the most basic life functions.
     Through the uncontrolled use of insecticides, man has polluted the land, killing the wildlife. By dumping sewage and chemicals into rivers and lakes, we have contaminated our drinking water. We are polluting the ocean, too, killing the fish and thereby depriving ourselves of an invaluable food supply.
     Part of the problem is our exploding population. More and more people produce more wastes. But this problem is intensified by our “throw-away” technology. Each year Americans dispose of 7 million autos, 20 million tons of waste paper plates. It is easier and cheaper to buy a new one and discard the old, even though 95 percent of its parts may still be functioning. Baby’s diapers, which used to be made of reusable cloth, are now paper throwaways. Soon we will wear clothing made of paper: “Wear it once and throw it away” will be the slogan of the fashion conscious.
     Where is this all to end? Are we turning the world into a gigantic dump, or is there hope that we can solve the pollution problem? Fortunately, solutions are in sight. A few of them are positively ingenious.

     Not all kids are cut out for college, despite the expectations of their parents or teachers. And especially in the brave new world of the 21st century, not all kids need to go to college right after high school―or ever―to succeed, says J. Michael Farr, author of America’s Top Jobs for People Without a Four-Year Degree

     And chances are, you will need training after high school through some form of alternative career education. Only four of the fastest growing occupations in the United States require a four-year degree or more, says Unger, author of But What if I Don’t Want to Go to College? But many of the others—home health aides, building maintenance, teaching aides—require post-high-school training.
     Which vocational education and training you’ll need—and the cost—depends upon the vocation you choose. Public community colleges offer some of the best vocational training, often specializing in areas such as the graphic arts, hotel and restaurant management, and building trades, according to Unger. Fulltime tuition averages $1,200 a year, although the range from state-to-state is $600 to $3,500. Vocational training at technical institutes will be costlier. Private junior colleges average $7,000 a year, according to Unger. Tuition for private-for-profit trade schools that usually specialize in one field, such as hair-styling or auto mechanics, varies widely, and Unger warns students to be wary of unethical operators. 

     Not just any vocational education or training will do. The trick is to find reputable, high-quality programs and to avoid con artists and dead-end programs, advises Unger. Look for programs that are accredited, offer in-depth academic and vocational instruction, teach real skills for real jobs, provide hands-on work experience, help students in job-hunting, and are linked to potential employers.
     Too often, Unger argues, parents push their reluctant children to go to college. Many drop out. “We are forcing hundreds of thousands of kids to go to college and they clearly do not want to be there,” he says.
     What about high school graduates who don’t want college and don’t know what to do next? Start by visiting your school guidance office or library to thumb through The Occupational Outlook Handbook published every two years by the U.S. Labor Department. It offers nuts-and-bolts descriptions of jobs and the training required.
     Think about what interests you—sports, music, gardening, whatever—and what jobs let you pursue that interest, advises Unger. Visit people who do these jobs. Ask questions.

     Do pigeons use their biological clocks to help them find directions from the sun? We can keep pigeons in a room lit only by lamps. And we can program the lighting to produce artificial "days", different from the day outside. After a while we have shifted their clocks. Now we take them far away from home and let them go on a sunny day. Most of them start out as if they know just which way to go, but choose a wrong direction. They have picked a direction that would be correct for the position of the sun and the time of day according to their shifted clocks.
     We have talked about one of the more complex experiments that lead to the belief that homing pigeons can tell directions by the sun. But what happens when the sky is darkly overcast by clouds and no one can see where the sun is? Then the pigeons still find their way home. The same experiment has been repeated many times on sunny days and the result was always the same. But on very overcast days clock-shifted pigeons are just as good as normal pigeons in starting out in the right directions. So it seems that pigeons also have some extra sense of direction to use when they cannot see the sun.
     Naturally, people have wondered whether pigeons might have a build-in compass—something that would tell them about the directions of the earth’s magnetic field. One way to test that idea would be to see if a pigeon's sense of direction can be fooled by a magnet attached to its back. With a strong magnet close by, a compass can no longer tell direction.

     Animals perform many useful and entertaining jobs. Dogs are particularly valuable in guiding the blind, protecting property, finding lost people, and hunting down criminals. Horses are used in guarding herds; carrying men in lands where there are no roads, and helping farmers work their land. Pigeons have long been used to carry messages. Wild animals from the jungles, forests and seas are very popular performers in circuses and movies. People realize that, although animals may not have the same intelligence as human beings, they are smart enough to learn certain things.

     Dogs are extremely useful as companions for blind people. When a dog has been properly trained, he will always lead his blind master in the right direction and keep him out of danger.

    Of all the sports that America has to offer, baseball is considered the pastime of this country. Americans did not always regard baseball and other sports in such a benign manner. Rather, sports during the early colonial times were seen as pagan and devilish things to do. Many elite and wealthy gentry who embodied the Victorian ideals regarded any type of games or sports as ill vices. It was the common people who directly related sports to their religion. On days of religious celebration, early Americans joined together to play games. These folk games were unstructured and unruly; however, the unity that these games brought, created a need for professional sporting games. Folk games provided the foundation of sports. They created a sense of companionship and unison among individuals. These unorganized folk games created the threshold for organized sports and led to the transformation of the players' roles and the role of the audience. Amateurs became professional athletes, and the game an organized business. The game of baseball evolved from the English game of cricket and rounders. It was not until the time of the Civil War that baseball began to be played frequently.
    However with the transformation of the nation, society and technology, folk games too began to evolve into spectator sports. After the Civil War, baseball became a popular sport and no longer an archaic folk game. Structure and organization were introduced gradually into the game and increased public participation. The sport at first excluded the public, but as economic interests infiltrated the game, the need for audiences and spectators arose. The audience of baseball was instrumental in the transformation of baseball. The battling leagues and team rivalries created a sector for the American public to participate in baseball.
    Baseball emerged after the end of Civil War as a popular game.The popularity of rivalries fueled the attraction of the game and caused it to become the national pastime. The sport transformed from being a game of amateurs into a sport played by professionals. With that transformation, the innocence of baseball has been lost. The game of baseball went through many transformations. Once the owners took control, baseball had its ups and downs. The sport experienced a dead ball era in which pitching was well below the standard of today. Also, with new technological advances in the game, the sport reached its pinnacle. With improved balls, bats, and gloves the sport took off and the dead ball era came to a close. The live ball era increased the role of the audience.

     Research in industrialized countries has shown the subtle method used to encourage girls to smoke. The impact of such method is likely to be even greater in developing countries, where young people are generally less knowledgeable about smoking hazards and may be more attracted by glamorous, affluent, desirable images of the female smoker. This is why WHO, together with other national and international health agencies, has repeatedly called for national legislation banning all forms of tobacco promotion, and for an appropriate “high price” policy which would slow down the “enthusiasm” of young women for tobacco consumption.
     Young girls and women have a right to be informed about the damage that smoking can do to their health. They also need to acquire skills to resist pressure to start smoking or to give it up. Several countries have developed integrated school and preschool health education programs which have successfully reduced girls’ smoking rates; but this education should not be restricted to what happens in school. There are many other examples of effective cessation programs in the workplace and primary health centers. Unfortunately, many women do not have the opportunity to be involved in such programs, and programs have generally been less successful with women than men.
     In order for women to become, and remain, non-smokers they need support. Support over these difficult days when the addiction cycle is broken. Support to help them deal in other less damaging ways with the reasons that caused them to smoke. Environments need to be created which enable them to break free of this health damaging behavior, to make the healthy choices the best choices. Smoking amongst women has already reached epidemic proportions and will continue to escalate unless action is taken now. Delays can only cause further suffering and deaths of women; this is why WHO’s new program on tobacco or health is giving high priority to action to protect women and children.

     1. Communication networks are arrangements of hardware and software that allow users to exchange information. This very broad definition will help you begin learning about one of the fastest-growing areas in electrical engineering and computer science. Once we examine some common communication networks, we will develop a more precise definition. We will elaborate on the importance of this field.
     2. The telephone network is the most familiar and ubiquitous communication network. It is designed for voice transmission. An office computer network is a communication network used by organizations to connect personal computers and workstations so they may share programs and data and to link those computers to printers and, possibly, to some other peripherals (e.g., file servers that provide mass storage or plotters). Computer networks also are used in manufacturing plants to connect machine tools, robots, and sensors. The Internet is a network of computer networks that covers most of the world and allows millions of users to exchange messages and computer files and some limited video and audio signals.
     3. Although all these systems are communication networks, they are quite different in the information that they transmit and in the way they are used. Nevertheless, they operate on similar principles. The unifying characteristics of all networks help us develop a definition of communication networks that describes the arrangements of hardware and software that we study in this text. Each system described is designed to exchange information, which may be voice, sounds, graphics, pictures, video, text, or data, among users. Most often the users are humans, but they also can be computer programs or devices. Before the information is transmitted, it is converted into bits (zeros or ones). Then the bits are sent to a receiver as electrical or optical signals (electromagnetic waves, to be more precise). Finally, the information is reconstructed from the received bits. This transmission method, called digital transmission, reduced the transmission errors.

       About three hundred years ago, there were approximately half a billion people in the world. In the two centuries that followed the population doubled, and, by 1850, there were more than a billion people in the world. It took only 75 years for the figure to double once more, so that now the population figure stands at approximately six and one half billion. Each day the population of the world increases by about 150,000.
