Any list of the greatest thinkers in history contains the name of the brilliant German physicist Albert Einstein. His theories of relativity led to entirely new ways of thinking about time, space, matter, energy, and gravity. Einstein's work led to such scientific advances as the control of atomic energy, even television as a practical application of Einstein's work. In 1902 Einstein became an examiner in the Swiss patent office at Bern. In 1905, at age 26, he published the first of five major research papers. The first one provided a theory explaining Brownian movement, the zig-zag motion of microscopic particles in suspension. The second paper laid the foundation for the photon, or quantum, theory of light. In it he proposed that light is composed of separate packets of energy, called quanta or photons, that have some of the properties of particles and some of the properties of waves. A third paper contained the "special theory of relativity" which showed that time and motion are relative to the observer, if the speed of light is constant and the natural laws are the same everywhere in the universe. The fourth paper was a mathematical addition to the special theory of relativity. Here Einstein presented his famous formula, E = m(cc), known as the energy mass equivalence. In 1916, Einstein published his general theory of relativity. In it he proposed that gravity is not a force, but a curve in the space-time continuum, created by the presence of mass. Einstein spoke out frequently against nationalism, the exalting of one nation above all others. He opposed war and violence and supported Zionism, the movement to establish a Jewish homeland in Palestine. When the Nazis came to power in 1933, they denounced his ideas. He then moved to the United States. In 1939 Einstein learned that two German chemists had split the uranium atom. Einstein wrote to President Franklin D. Roosevelt warning him that this scientific knowledge could lead to Germany developing an atomic bomb. He suggested the United States begin its own atomic bomb research.

The goal of Internet-based encyclopedia Wikipedia (www.wikipedia.org) is to give everyone on the planet access to information. Like other encyclopedias, Wikipedia contains lots of information: more than 2.5 million articles in 200 different languages covering just about every subject. Unlike other encyclopedias, however, Wikipedia is not written by experts, but by ordinary people. These writers are not paid and their names are not published. They contribute to Wikipedia simply because they want to share their knowledge.

Encyclopedias began in ancient times as collections of writings about all aspects of human knowledge. The word itself comes from ancient Greek, and means "a complete general education". Real popularity for encyclopedias came in the nineteenth century in Europe and the United States, with the publication of encyclopedias written for ordinary readers. With the invention of the CD- ROM, the same amount of information could be put on a few computer discs. Then with the Internet, it became possible to create an online encyclopedia that could be constantly updated, like Microsoft's Encarta. However, even Internet-based encyclopedias like Encarta were written by paid experts. At first, Wikipedia, the brainchild of Jimmy Wales, a businessman in Chicago, was not so different from these. In 2001, he had the idea for an Internet-based encyclopedia that would provide information quickly and easily to everyone. Furthermore, that information would be available free, unlike other Internet encyclopedias at that time.

But Wales, like everyone else, believed that people with special knowledge were needed to write the articles, and so he began by hiring experts. He soon changed his approach, however, as it took them a long time to finish their work. He decided to open up the encyclopedia in a radical new way, so that everyone would have access not only to the information, but also to the process of putting this information online. To do this, he used what is known as "Wiki" software (from the Hawaiian word for "fast"), which allows users to create or alter content on web page. The system is very simple: When you open the web site, you can simply search for information or you can log on to become a writer or editor of articles. If you find an article that interests you - about your hometown, for example - you can correct it or expand it. This process goes on until no one is interested in making any more changes.

Until the 19th century, the denial of equal rights to women met with only occasional protest and drew little attention from most people. Because most women lacked the educational and economic resources that would enable them to challenge the prevailing social order, women generally accepted their inferior status as their only option. At this time, women shared these disadvantages with the majority of working class men, as many social, economic, and political rights were restricted to the wealthy elite.In the 19th century, as governments in Europe and North America began to draft new laws guaranteeing equality among men, significant numbers of women – and some men – began to demand that women be accorded equal rights as well.
At the same time, the Industrial Revolution in Europe and North America further divided the roles of men and women. Before the Industrial Revolution most people worked in farming or crafts-making, both of which took place in or near the home. Men and women usually divided the numerous tasks among themselves and their children. Industrialization led male workers to seek employment outside of the home in factories and other large-scale enterprises. The growing split between home and work reinforced the idea that women’s “rightful place” was in the home, while men belonged in the public world of employment and politics.
Organized efforts by women to achieve greater rights occurred in two major waves. The first wave began around the mid-19th century, when women in the United States and elsewhere campaigned to gain suffrage that is, the right to vote. This wave lasted until the 1920s, when several countries granted women suffrage

Until the 19th century, what was the status of the working class men in the society?

Why is it that flying to New York from London will leave you feeling less tired than flying to London from New York? The answer may be a clear case of biology not being able to keep up with technology.
Deep inside the brain there is a "clock" that governs every aspect of the body's functioning: sleep and wake cycles, levels of alertness, performance, mood, hormone levels, digestion, body temperature and so on. It regulates all of these functions on a 24-hour basis and is called the circadian clock (from the Latin, circa "about" + dies "day"). This body clock programmes us to be sleepy twice a day, between 3-5 a.m and again between 3-5 p.m.
Afternoon tea and siesta times are all cultural responses to our natural biological sleepiness in the afternoon.
One of the major causes of the travelers' malady known as jet lag is the non-alignment of a person's internal body clock with clocks in the external world. Crossing different time zones confuses the circadian clock, which then has to adjust to the new time and patterns of light and activity. To make matters more complex, not all internal body functions adjust at the same rate. So your sleep/wake may adjust to a new time zone at one rate, while your temperature adjusts at a different pace. Your digestion may be on a different schedule altogether.
Though we live in a 24-hour day, the natural tendency of the body clock is to extend our day beyond 24 hours. It is contrary to our biological programming to shrink our day. That is why traveling in a westward direction is more body-clock friendly than flying east. NASA studies of long haul pilots showed that westward travel was associated with significantly better sleep quantity and quality than eastward flights.
When flying west, you are "extending" your day, thus traveling in the natural direction of your internal clock. Flying eastward will involve "shrinking" or reducing your day and is in direct opposition to your internal clock's natural tendency. One of the more common complaints of travelers is that their sleep becomes disrupted. There are many reasons for this: Changing time zones and schedules, changing light and activity levels, trying to sleep when your body clock is programmed to be awake, disruption of the internal circadian clock and working longer hours.
Sleep loss, jet lag and fatigue can seriously affect our ability to function well. Judgment and decision-making can be reduced by 50%, attention by 75 percent, memory by 20 percent and communication by 30 percent.
It is often suggested that you adjust your watch as soon as you board a plane, supposedly to try to help you adjust to your destination's schedule as soon as you arrive. But it can take the body clock several days to several weeks to fully adjust to a new time zone.

According to the author, which of the following reasons disrupt travelers' sleep?

Leonardo da Vinci was born on April 15,1452, in the small Tuscan town ofVinci, near Florence. He was the son of a wealthy Florentine public official and a peasant woman. In the mid-1460s, the family settled in Florence, where Leonardo was given the best education that Florence could offer. He rapidly advanced socially and intellectually. He was handsome, persuasive in conversation, and a fine musician and improviser. About in 1466 he apprenticed as a studio boy to Andrea Del Verrocchio. In Verrocchio's workshop, Leonardo was introduced to many activities, from the painting of altarpieces and panel pictures to the creation of large sculptural projects. In 1472, he was entered in the painter's guild of Florence, and in 1476, he was still mentioned as Verrocchio's assistant. In Verrocchio's Baptism of Christ, the kneeling angel at the left of the painting is by Leonardo.
In 1478, Leonardo became an independent master. His first commission, to paint an altarpiece for the chapel of the Palazzo Vecchino, the Florentine town hall, was never executed. His first large painting, The Adoration of the Magi, left unfinished, was ordered in 1481 for the Monastery of San Donato a Scopeto, Florence. Other works ascribed to his youth are the so-called Benois Madonna, the portrait Ginerva de' Bend, and the unfinished Saint Jerome.
In 1482, Leonardo's career moved into high gear when he entered the service of the duke of Milan, Ludovico Sforza, having written the duke an astonishing letter in which he stated that he could build portable bridges; that he knew the techniques of constructing bombardments and of making cannons; that he could build ships as well as armored vehicles, catapults, and other war machines; and that he could execute sculpture in marble, bronze, and clay. He served as a principal engineer in the duke’s numerous military enterprises and was so active also as an architect. In addition, he assisted the Italian mathematician Luca Pacioli in the celebrated work Divina Proportione.

   Over the past 600 years, English has grown from a language of few speakers to become the dominant language of international communication. English as we know it today emerged around 1350, after having incorporated many elements of French that were introduced following the Norman invasion of 1066. Until the 1600s, English was, for the most part, spoken only in England and had not extended even as far as two centuries, English began to spread around the globe as a result of exploration, trade (including slave trade), colonization, and missionary work. Thus, small enclaves of English speakers became established and grew in various parts of the world. As these communities proliferated, English gradually became the primary language of international business, banking and diplomacy.

   Currently, about 80 percent of the information stored on computer systems worldwide is English. Two thirds of the world’s science writing is in English, and English is the main language of technology, advertising, media, international airports, and air traffic controllers. Today there are more than 700 million English users in the world, and over half of these are nonnative speakers, constituting the largest number of non-native users than any other language in the world..

A pioneering study by Donald Appleyard made the astounding discovery that a sudden increase in the volume of traffic through an area affects people in the way that a sudden increase in crime does. Appleyard observed this by finding three blocks of houses in San Francisco that looked much alike and had the same kind of middle-class and working-class residents, with approximately the same ethnic mix. The difference was that only 2,000 cars a day ran down Octavia Street (LIGHT street, in Appleyard’s terminology) while Gough Street (MEDIUM street) was used by 8,000 cars daily, and Franklin Street (HEAVY street) had around 16,000 cars a day. Franklin Street often had as many cars in an hour as Octavia had in a day.
Heavy traffic brought with it danger, noise, fumes and soot, directly, and trash secondarily. That is, the cars didn’t bring in much trash, but when trash accumulated, residents seldom picked it up. The cars, Appleyard determined, reduced the amount of territory residents felt responsible for. Noise was a constant intrusion into their homes. Many Franklin Street residents covered their doors and windows and spent most of their time in the rear of their houses. Most families with children had already left.
Conditions on Octavia Street were much different. Residents picked up trash. They sat on their front steps and chatted with neighbors. They had three times as many friends and twice as many acquaintances as the people on Franklin.
On Gough Street, residents said that the old feeling of community was disappearing as traffic increaseD. People were becoming more and more preoccupied with their own lives. A number of families had recently moved and more were considering. Those who were staying expressed deep regret at the destruction of their community.

In what order does the author present detailed discussions of the three streets?

Until recently, most American entrepreneurs were men. Discrimination against women in business, the demands of caring for families, and lack of business training had kept the number of women entrepreneurs small. Now, however, businesses owned by women account for more than $40 billion in annual revenues, and this figure is likely to continue rising throughout the 1990s. As Carolyn Doppelt Gray, an official of the Small Business Administration, has noted, “The 1970s was the decade of women entering management, and the 1980s turned out to be the decade of the woman entrepreneur". What are some of the factors behind this trend? For one thing, as more women earn advanced degrees in business and enter the corporateworld, they are finding obstacles. Women are still excluded from most executive suites. Charlotte Taylor, a management consultant, had noted, "In the 1970s women believed if they got an MBA and worked hard they could become chairman of the board. Now they've found out that isn't going to happen, so they go out on their own".
In the past, most women entrepreneurs worked in "women's" fields: cosmetics and clothing, for example. But this is changing. Consider ASK Computer Systems, a $22-million-a-year computer software business, it was founded in 1973 by Sandra Kurtzig, who was then a housewife with degrees in math and engineering. When Kurtzig founded the business, her first product was software that let weekly newspapers keep tabs on their newspaper carriers-and her office was a bedroom at home, with a shoebox under the bed to hold the company's cash, After she succeeded with the newspaper software system, she hired several bright computer-science graduates to develop additional programs. When these were marketed and sold, ASK began to grow. It now has 200 employees, and Sandra Kurtzig owns $66.9 million of stock.
Of course, many women who start their own businesses fail, just as men often do. They still face hurdles in the business world, especially problems in raising money; the banking and finance world is still dominated by men, and old attitudes die hard. Most businesses owned by women are still quite small But the situation is changing; there are likely to be many more Sandra Kurtzigs in the years ahead.

What is the main idea of this passage?

In addition to their military role, the forts of the nineteenth century provided numerous other benefits for the American West. The establishment of these posts opened new roads and provided for the protection of daring adventurers and expeditions as well as established settlers. Forts also served as bases where enterprising entrepreneurs could bring commerce to the West, providing supplies and refreshments to soldiers as well as to pioneers. Posts like Fort Laramie provided supplies for wagon trains traveling the natural highways toward new frontiers. Some posts became stations for the pony express; still others, such as Fort Davis, were stagecoach stops for weary travelers. All of these functions, of course, suggest that the contributions of the forts to the civilization and development of the West extended beyond patrol duty.
 Through the establishment of military posts, yet other contributions were made to the development of western culture. Many posts maintained libraries or reading rooms, and some – for example, Fort Davis – had schools. Post chapels provided a setting for religious services and weddings. Throughout the wilderness, post bands provided entertainment and boosted morale. During the last part of the nineteenth century, to reduce expenses, gardening was encouraged at the forts, thus making experimental agriculture another activity of the military. The military stationed at the various forts also played a role in civilian life by assisting in maintaining order, and civilian officials often called on the army for protection.
 Certainly, among other significant contributions the army made to the improvement of the conditions of life was the investigation of the relationships among health, climate, and architecture. From the earliest colonial times throughout the nineteenth century, disease ranked as the foremost problem in defense. It slowed construction of forts and inhibited their military functions. Official documents from many regions contained innumerable reports of sickness that virtually incapacitated entire garrisons. In response to the problems, detailed observations of architecture and climate and their relationships to the frequency of the occurrence of various diseases were recorded at various posts across the nation by military surgeons.

The author organizes the discussion of forts by ________.
