You’ll be able to purchase high-quality emotions online. Emotion-sharing experiences  are the latest fad in 2045. Imagine your friend at Glastonbury can post a photo on Instagram and with it comes bundled a faint twinkling of what she was feeling right there in that moment, so you too can share emotionally in her social experience.  Recently, techniques for direct brain stimulation, like opt genetics, have made it possible to not only read but also write information into single neurons. At the moment data transfer rates are still very slow, the best we can do is a few bits per second, but this could well increase to kilobits or maybe reach broadband speeds by 2045. This means the range of human perception could expand beyond its current design limitations. One could foresee a new and extraordinary world where there is a virtual marketplace for trading high quality emotions – where artists looking for a particularly high strength brew of melancholy, or actors needing to channel regret or compassion for their next play, could purchase emotions online.  Our cities will be made from living, dynamic materials that respond to the environment. In 30 years, tall buildings made of glass and twisted steel will be seen as relics from a bygone era, in the same way we think now of 1970s concrete tower blocks: ugly, outdated and unfit for contemporary purpose. The urban environment of 2045 blends architecture with living materials that are mouldable, adaptable, responsive and disposable.  Entirely new synthetic life forms, or biological machines, made of engineered living cells from bacteria, fungi and algae will grow and evolve with the changing needs of a building’s inhabitants. They breathe in pollutants, clean wastewater, and use sunlight to make useful chemicals, energy, heat and vibrant vertical gardens. We will start to see a convergence between biology and technology, to the point where there is no longer a perceptible difference between the two. Today, synthetic biology labs are looking at the full diversity of what nature has to offer and using this to mix, match and edit genomes to design synthetic life forms. Right now, this field is just getting started and the science of synthetic biology is going to be tougher than most will admit.  We will use invisibility cloaks to “disappear” ugly objects. Invisibility has forever been a tantalizing prospect. The key to cloaking lies in the way the electromagnetic spectrum  (including visible light) interacts with objects. The human eye picks up electromagnetic radiation that falls and scatters from objects and we perceive this as light. In recent decades, scientists figured out using mathematics that it might just be possible to imagine a new class of artificial materials made of intricate tiny features with light bending properties. They named them metamaterials.  Using nanotechnology engineering, scientists have since shown cloaking actually works – in principle at least, for a narrow range of colours and only from certain viewing angles. The future applications of cloaking are highly uncertain and will likely be determined by the fads and social contagion of the time. They may be used in everything from novelty gimmicks to making unsightly construction sites and power stations seemingly ‘disappear’.

With exams approaching, you should be thinking about how to get better at time management and organize your days so you can strike the right balance between home, work and university life. You should also try and eat some brain food - and no, we don’t mean crisps and energy drinks! By taking the time to arrange your priorities, you can give yourself the best chance of staying on track and being organized during the exam period, which in turn can help reduce stress levels, something that can be the difference between success and failure at university. Take a look at our top time management tips, so that you can do your best at university and also find moments to relax and even earn some money on the side. First and foremost, allow time for planning to avoid repetition. Taking the time to research, plan and think about your work is crucial for good time management. Allow yourself the time to process new information and plan how you are going to use it, as this can help you to avoid having to re-read and repeat any research. One way of effectively planning before researching is to make a list of everything you want to find out, so that you can make notes below each subheading as you go Secondly, avoid procrastination and distraction. One way to avoid procrastination is to think about the different places you have been when studying - where were you the most focused? Where were you most distracted? Is there anything you can do to make studying actually somewhat enjoyable? Remember, what works for one person might not necessarily work for you. For some, studying with friends can limit their productivity. But for others, studying in groups can help to increase motivation and avoid procrastination. Next, exercise to clear your head in between study sessions. Believe it or not, exercise works in the same way sleep does. It can focus your state of mind, helping you to clear your head and boost your brain power in between study sessions. If you’re new to exercise, aim to fit in a 10-minute run here and there, steadily increasing the amount you do as you go on. Finally, ask yourself the question, “Has your organization been effective?” Constantly reviewing and reassessing your schedule can help you to recognize whether you need to make any changes in order to help you complete any university tasks and also have time to relax and spend time with friends and family.

Read the following passage and choose the best answer (A, B, C, D):
Diseases are a natural part of life on earth. If there were no diseases, the population would grow too quickly, and there would not be enough food or other resources, so in a way, diseases are natural ways of keeping the Earth in balance. But sometimes they spread very quickly and kill large numbers of people. For example, in 1918, an outbreak of the flu across the world, killing over 25 million people only in six months. Such terrible outbreaks of a diseases are called pandemics. Pandemics happen when a disease changes in a way that our bodies are not prepared to fiht. In 1918, a new type of fl virus appeared. Our bodies had no way to fiht this new flu virus, and so it spread very quickly and killed large numbers of people. While there have been many different pandemic diseases throughout history, all of them have a new thing in common. First, all pandemic diseases spread from one person to another very easily. Second, while they may kill many people, they generally do not kill people very quickly. A good example of this would be the Marburg virus. The Marburg virus is an extremely infectious disease. In addition, it is deadly. About 70%-80% of all people who get the Marburg virus died from the disease. However, the Marburg virus has not become a pandemics because most people die within three days of getting the disease. This means that the virus does not have enough time to spread a large number of people. The flu virus of 1918, on the other hand, generally took about a week to ten days to kill its victims, so it had more time to spread. While we may never be able to completely stop pandemics, we can make them less common. Doctors carefully monitor new disease that they fear could become pandemics. For example, in 2002, and 2003, doctors carefully watched SARS. Their health warming may have prevented SARS from becoming a pandemic.

Accustomed though we are to speaking of the films made before 1927 as “silent”, the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment; when the Lumiere films were shown at the first public film exhibition in the United States in February 1896, they were accompanied by piano improvisations on popular tunes. At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient. Within a very short time, however, the incongruity of playing lively music to a solemn film became apparent, and film pianists began to take some care in matching their pieces to the mood of the film.
As movie theaters grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain cases, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program rested entirely in the hands of the conductor or leader of the orchestra, and very often the principal qualification for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before the y were to be shown (if, indeed, the conductor was lucky enough to see them then), the musical arrangement was normally improvised in the greatest hurry.
To help meet this difficulty, film distributing companies started the practice of publishing suggestions for musical accompaniments. In 1909, for example, the Edison Company began issuing with their films such indications of mood as “pleasant’, “sad”, “lively”. The suggestions became more explicit, and so emerged the musical cue sheet containing indications of mood, the titles of suitable pieces of music, and precise directions to show where one piece led into the next.

Certain films had music especially composed for them. The most famous of these early special scores was that composed and arranged for D. w. Griffith’s film Birth of a Nation, which was released in 1915.

It can be inferred that orchestra conductors who worked in movie theaters needed to............

It’s probably the most painstaking, heart wrenching, and stress inducing test of dedication a marriage can face. But the reward at the end is pretty sweet. At the annual Wife Carrying World Championships in Sonkajärvi, Finland, male competitors race around a track hauling their female partners on their backs. Winner takes home his wife’s weight in beer. It’s no ordinary racetrack, either. Competitors must wade through a neck-deep pool of water, climb over hurdles, and run through pits of sand before crossing the finish line. While some participants don crazy costumes for the pre-race, the actual event is pretty straightlaced. Wives must weigh at least 49 kilograms (108 pounds). Any woman lighter than that is required to carry a heavy rucksack until she reaches this minimum. A participant who drops his wife will be penalized 15 seconds. But there is one catch: contestants don’t have to carry their own wives. A friend’s wife, stranger’s wife, or even a random grandmother will do – as long as she’s over 17. Contestants flock from 47 countries across the globe to show their stuff in this epic display of brute strength. This year, Finnish couple Taisto Miettinen and Kristiina Haapanen captured the title for the fourth consecutive year. The 46-year-old lawyer and his wife completed the 235-meter course in one minute and four seconds. Like any dedicated athlete, Miettinen reported that he’d been training for a while. “In last autumn, I started running in the track, one hundred, two hundred and four hundred meters,” Miettinen said in a post-race interview. He also practiced the course in ski boots to build leg strength. The competition, which began in 1992, is supposedly rooted in the legend of Ronkainen the Robber — a hardnosed gang leader who hazed potential members by making them lug sacks of grain or live pigs over a similar course. He and his comrades also made a habit of stealing women from neighboring villages as a nod to this practice, many men “steal” friends’ wives for the competition. If you want to compete but can’t make it to Finland, there’s a North American version of the contest held in October at Sunday River Resort in Maine. With 100-plus pounds of brewski on the line, you might want to tell your significant other to start shaping up.

Read the following passage and choose the best answer (A, B, C, D):
Whether a species is endangered—meaning at risk of extinction—depends on which definition you use. The International Union for Conservation of Nature’s Red List of Threatened Species classifies an animal as endangered when its numbers in the wild have dropped so low that it’s at “extremely high risk” of extinction. Meanwhile, the United States’ Endangered Species Act of 1973 takes into consideration any destruction to a species’ habitat, whether it has been over-consumed, any disease or predation that threaten it, whether any other man-made factors put it in danger, and what policies currently exist to protect it. When members of the public or a state agency propose to the U.S. Fish & Wildlife Service or the National Marine Fisheries Service that a species be listed as endangered under the law, research and management plans are formed to help those species survive. It is illegal under the Endangered Species Act to capture, hunt, shoot, or otherwise harm an animal that’s listed as endangered. Sometimes, federal agencies decide that although a species could be considered endangered, other species are higher priorities. In those cases, the animal or plant gets limited protections. One animal whose numbers have increased through conservation is the bald eagle. There were only about 500 bald eagles in the continental United States in the 1960s because of pesticides that damaged the shells of their eggs. Conservation efforts including captive breeding programs, habitat protection, and a ban on the insecticide DDT helped the bald eagle’s numbers soar back into the thousands. Another is the giant panda, which was declared no longer endangered in 2016 thanks to 50 years of efforts to save it. U.S. Rep. John Dingell, who wrote the Endangered Species Act, argued that “only natural extinction is part of natural order.” Scientists believe that 227 species - including the grizzly bear, the peregrine falcon and the gray wolf - were saved from extinction in the first 33 years of the law’s existence. Still, critics argue that the act is expensive and ineffective because it protects so many species. Several federal courts have heard and rejected arguments that the Endangered Species Act is unconstitutional, and members of Congress have tried to weaken the law in small ways.

If you were going to choose a job that involves travel, what would be your first choice? There are many jobs available today that give people opportunities to travel. Although may traveling careers sound fantastic, they also have disadvantages.
Being an au pair is an excellent way to not only go to different countries, but to live in different places around the world and really get a feel for the culture. Au pairs lives with the families they are placed with and take of children. Many parents include au pairs in family events and vacations, so they experience many aspects of the new culture while on the job. However, many of the activities are centered around the children, so they may not get to experience many things that interest adults.
For people who want a bit more freedom working abroad, being an English teacher maybe a good choice. There are English teaching jobs in almost countries in the world. People teaching English in other countries often have a chance to travel on the weekends around the country. One drawback is that many teachers often wind up hanging out with other English teachers, and they don’t have time to learn the country’s language.
The nickname “roadie” implies that this job involves life on the road. Roadies are people who work and travel with bands and provide technical support. Roadies can be lighting and stage crew who set up the stage and break it down before and after events. They can also be technicians helping band members with their instruments. International tours take a band’s crew to cities around the world, often requiring air travel. However, the crew doesn’t get much time off, so they may travel to several countries without seeing much besides concert venues and hotels.
Similarly, flight attendants often travel to cities around the world, but they don’t see much besides the inside of airplanes and hotels. However, when they do have time off, they can often fly at no cost, and family member can sometimes fly free as well. Its is widely thought that a flight attendant job is
glamorous, but flight attendants must deal with travel hassles, as well as security issues.
All jobs gave advantages and disadvantages whether or not you travel for work, so if you have the travel bug, keep these jobs in mind for the future.

"Most young couples have meals regularly in their parents’ home with little or no pay, and give their children to the care of old couple free of charge. Investigations have shown that parents of many young couples don’t mind providing meals and caring for their children. However, this practice should not become an accepted social custom. The old couples’ expense on food has already increased while young couples spend more on clothing and furnishing and less on food. If this trend continues, many young couples might take these privileges for granted and become more dependent. It is not the right for young people to make use of the old couples’ love, not only because our nation is well-known for its special respect paid to the elderly, but also because the young must become independent What young people should do is to become more considerate towards their old parents.

Today, population growth largely means urban population growth. UN projections  show the world’s rural population has already stopped growing, but the world can expect to add close to 1.5 billion urbanites in the next 15 years, and 3 billion by 2050. How the world meets the challenge of sustainable development will be intimately tied to this process.  For many people, cities represent a world of new opportunities, including jobs. There is a powerful link between urbanization and economic growth. Around the world, towns and cities are responsible for over 80 per cent of gross national product. While urban poverty is growing around the world, this is largely because many people – including the poor – are moving to urban areas.  The opportunities there extend beyond just jobs. Cities also offer greater opportunities for social mobilization and women’s empowerment. Many young people, especially young women, regard the move to cities as an opportunity to escape traditional patriarchy and experience new freedoms. Urban areas also offer greater access to education and health services, including sexual and reproductive health care, further promoting women’s empowerment and the realization of their reproductive rights. This contributes to significantly reduced fertility in urban areas, changing the trajectory of overall population growth.  The urbanization process – which is particularly pronounced in Africa and Asia, where much of the world’s population growth is taking place – is also an enormous opportunity for sustainability, if the right policies are put in place. Urban living has the potential to use resources more efficiently, to create more sustainable land use and to protect the biodiversity of natural ecosystems. Still, the face of inequality is increasingly an urban one. Too many urban residents grapple with extreme poverty, exclusion, vulnerability and marginalization. Urban land is expanding much faster than urban population, a phenomenon known as urban sprawl. It is driven in part by increasing urban land consumption by the wealthy and the increasing separation of rich and poor communities within cities. Sprawl undermines the efficiencies of urban living, and it marginalizes poor people in remote or peripheral parts of cities, often in dense informal settlements or slums.  This phenomenon can eliminate the very opportunities people seek when they move to cities. Many people in slums lack ready access to health facilities. Others rely on private, unregulated providers for health services that are free in rural areas. In some urban slums, poor women have fertility rates closer to those of rural women. The urban poor also face risky and unhealthy living conditions, such heavy pollution or high vulnerability to disasters.  The total estimated number of slum dwellers is rising – from over 650 million in 1990 to about 863 million in 2012. Almost 62 per cent of the urban population in sub-Saharan Africa lived slums in 2010, the highest proportion of any region. But slum growth is not the same as urbanization. Most evidence suggests that global urbanization is an inevitable trend, while slum growth results from the decisions to limit poor people’s access to cities, through limited service provision to informal settlements or by forced evictions and resettlement of the urban poor to peripheral or under-serviced areas.

Modern civilization is heavily dependent on energy. Without reliable power sources, e coulnt operate machines, use transportation, communicate via Internet, or do many other things. Although everyone recognizes the importance of energy, deciding what kind of energy the world should use in the future is not a simple task. The two leading candidates for this role are green energy and nuclear energy.
Currently, most of the energy we use is derived from fossil fuels. Although this energy source has got us this far, there are several problems with it. For starters, it is a finite resource which is quickly running out. Some analysts have even estimated that the Earth could run out of coal and oil within the next 50 years. Burning fossil fuels also creates large amount of pollution, which is harmful to the environment. Although fossil fuels still provide the majority of our power, governments are seeking better energy sources to use going forward.
Green energy is one option that is becoming increasingly attractive. It includes technologies such as solar, wind, and hydro power. These are seen as clean sources of energy because they cause very little pollution. In addition, they are completely renewable, so there is no danger that it will run out. The major disadvantage with green energy sources is that they are not cheap.
The other alternative is nuclear power. Like green energy, it is also a renewable source of power that will not run out, and it also doesn’t produce air pollution. In addition, nuclear power is more reliable than green energy, as it doesn’t depend on sunshine, rain, or wind to operate. The major issues with nuclear power are safety concerns and nuclear waste. Nuclear power plants create a considerable amount of nuclear waste which is extremely hazardous to people’s health. I they happen to have a meltdown, this could destroy the surrounding area for years to come.
The recent nuclear disaster in Fukushima, Japan brought this reality into the spotlight once again. In response, Germany announced it would close down eight of its nuclear plants immediately, and close the rest by 2022. Meanwhile, other nations refuse to give up on nuclear power, stating that these disasters are rare. The debate of whether to use green or nuclear power will likely continue for some time. In the end, it is quite possible that both energy sources will be used to fuel our planet.

What is the main problem with green energy?

Globally we use more energy than ever before, and the demand is rapidly growing. Economic expansion of emerging market economies, population growth and our increasing use of energy-consuming devices are among the most important contributing factors. About one-third of the radiation hitting Earth’s atmosphere is reflected back out into space by clouds, ice, snow, sand and other reflective surfaces. The other two-thirds is absorbed by the Earth’s surface and the atmosphere. As the land, oceans and atmosphere heat up, they re-emit energy as infrared thermal radiation, which passes through the atmosphere. Heat-trapping gases like carbon dioxide (CO2) absorb this infrared radiation and prevent it from dissipating into space, giving rise to what we know as the greenhouse effect. The accumulation of CO2 and other greenhouse gases in the atmosphere is the dominating driver of recent climate change. CO2 is estimated to be responsible for 64 % of man-made global warming. Other greenhouse gases are released in much smaller amounts but still contribute significantly to the overall warming effect, as they are much more potent heat-trapping gases than CO2. The EU is taking action on many levels. One example is on fluorinated gases that are contributing less than CO2 but still a particular point of concern in addressing climate change. They are used in several types of products, such as in refrigeration, air-conditioning and heat pump equipment. While fluorinated gases are released into the atmosphere in smaller quantities than other greenhouse gases, they are extremely potent – they produce a warming effect 23 000 times greater than CO2. For this reason the EU has decided to control their use. The EU’s regulation on fluorinated greenhouse gases aims at cutting the Union’s emissions by two-thirds compared to 2014 levels. Chemicals are not only part of the problem – they are also part of the solution. Sustainable energy sources like solar power rely on chemical innovation using, for example, nanomaterials. One of the main challenges with renewable energy is how to increase its viability with the help of energy storage solutions. For example, solar panels have the best conditions in the desert, but that is not where most people live. Windmills also produce power during the night, which is when our energy consumption is at its lowest. In other words, technologies to improve energy storage and transportation is one of the important areas of research where innovation is needed

It is said that George Washington was one of the first to realize how important tire building of canals would be to the nation’s development. In fact, before he became the President, he headed the first company in the United States to build a canal, which was to connect the Ohio and Potomac rivers. It was never completed, but it showed the nation the feasibility of canals. As the country expanded westward, settlers in western New York, Pennsylvania, and Ohio needed a means to ship goods. Canals linking natural waterways seemed to supply an effective method.
In 1791, engineers commissioned by the state of New York investigated the possibility of a canal between Albany on the Hudson River and Buffalo on Lake Eric to link the Great Lakes area with the Atlantic seacoast. It would avoid the mountains that served as a barrier to canals from the Delaware and Potomac rivers.
The first attempt to dig the canal, to be called the Eric Canal, was made by private companies but only a comparatively small portion was built before the project was halted for lack of funds. The cost of the prospect was estimated $5 million, an enormous amount for those days. There was some on-again-off-again federal funding, but this time the War of 1812 put an end to construction. In 1817, DeWitt Clinton was elected Governor of New York and persuaded the state to finance and build the canal. It was completed in 1825, costing S2 million more than expected.
The canal rapidly lived up to its sponsors’ faith, quickly paying for itself through tolls. It was far more economical than any other form of transportation at the time. It permitted trade between the Great Lake region and the East coast, robbing the Mississippi River of much of its traffic. It allowed New York to supplant Boston, Philadelphia, and other eastern cities as the chief center of both domestic and foreign commerce. Cities sprang up along the canal. It also contributed in a number of ways to the Norths victory over the South in the Civil War.
An expansion of the canal was planned in 1849. Increased traffic would undoubtedly have warranted its construction had it not been for the railroads.

In the mid - nineteenth century, the United States had tremendous natural resources that could be exploited in order to develop heavy industry. Most of the raw materials that are valuable in the manufacture of machinery, transportation facilities, and consumer goods lay ready to be worked into wealth. Iron, coal, and oil - the basic ingredients of industrial growth - were plentiful and needed only the application of technical expertise, organizational skill, and labor.

One crucial development in this movement toward industrialization was the growth of the railroads. The railway network expanded rapidly until the railroad map of the United States looked like a spider's web, with the steel filaments connecting all important sources of raw materials, their places of manufacture, and their centers of distribution. The railroads contributed to the industrial growth not only by connecting these major centers, but also by themselves consuming enormous amounts of fuel, iron, and coal.

Many factors influenced emerging modes of production. For example, machine tools, the tools used to make goods, were steadily improved in the latter part of the nineteenth century - always with an eye to speedier production and lower unit costs. The products of the factories were rapidly absorbed by the growing cities that sheltered the workers and the distributors. The increased urban population was nourished by the increased farm production that, in turn, was made more productive by the use of the new farm machinery. American agricultural production kept up with the urban demand and still had surpluses for sale to the industrial centers of Europe.

The labor that ran the factories and built the railways was recruited in part from American farm areas where people were being displaced by farm machinery, in part from Asia, and in part from Europe. Europe now began to send tides of immigrants from eastern and southern Europe - most of whom were originally poor farmers but who settled in American industrial cities. The money to finance this tremendous expansion of the American economy still came from European financiers for the most part, but the American were approaching the day when their expansion could be financed in their own " money market"
