Perfectly smart adults feel intimidated by numbers and aren’t ashamed to say, “I hate math.” The new book “Math Art” could help change that by making the dreaded topic relevant and accessible to naturalists, artsy types, the philosophically inclined, and committed calculators alike. It illuminates an old lesson your math teachers probably tried to convey when you were a kid: Math dominates our lives even while we try with all our might to ignore it. In Math Art, released in April, science writer Ornes examines creative works inspired by math. It’s an aesthetically pleasing book with a delightfully tactile cover and satisfyingly thick and glossy pages that make it as fun to flip through as a fashion magazine. Chapters are dedicated to different concepts like pi, the golden ratio, equations in nature, and hyperbolic geometry. All of which may sound scary to the uninitiated but gain appeal when illustrated through sculpture, crochet, and painting. As Ornes explains in the introduction, math art isn’t new. Since ancient times, humans have visualized math in creative works. He argues that what is new is the mutual recognition that mathematicians and artists now show each other, increasingly gathering together at events dedicated to the intersection of aesthetics and numbers. “This is art by way of math and math by way of art, beauty at the crossroads,” Ornes writes.  His exploration begins with pi, the irrational mathematical constant 3.14159, plus some, ad infinitum. Pi, the ratio of the circumference of a circle to its diameter, represents mystery itself. Because the sequence never repeats, pi hints at the vastness of the universe. “It speaks to a world without bounds, since its digits go on forever,” Ornes explains. Pi is used for calculations in math and physics, and employed by math artist John Sims to make music, videos, drawings, paintings, quilts, clothing, and stories. Sims created and taught a math curriculum for students at the Ringling College of Art and Design in Sarasota, Florida, and has spent much of his career at the intersection of math and creativity. In Ornes’ book, he explains how he’s also used this fascination to connect with other people he might not otherwise meet, such as the Amish quilters who joined him to make pi quilts with each colored panel representing a number in the mathematical sequence.

English teenagers are to receive compulsory cooking lessons in schools. The idea is to encourage healthy eating to fight the country’s increasing obesity rate. It’s feared that basic cooking and food preparation skills are being lost as parents turn to pre-prepared convenience foods. Cooking was once regarded as an important part of education in England – even if it was mainly aimed at girls. In recent decades cooking has progressively become a minor activity in schools. In many cases the schools themselves have given up cooking meals in kitchens in the schools. But the rising level of obesity has led to a rethink about the food that children are given and the skills they should be taught. “What I want is to teach young people how to do basic, simple recipes like a tomato sauce, a bolognaise, a simple curry, a stir-fry – which they can use now at home and then in their later life”, said Ed Balls, the minister responsible for schools. The new lessons are due to start in September, but some school without kitchens will be given longer to adapt. There is also likely to be a shortage of teachers with the right skills, since the trend has been to teach food technology rather than practical cooking. Also the compulsory lessons for hands on cooking will only be one hour a week for one term. But the well-known cookery writer, Pru Leith, believes it will be worth it. “If we’d done this thirty years ago we might not have the crisis we have got now about obesity and lack of knowledge about food and so on. Every child should know how to cook, not just so that they’ll be healthy, but because it’s a life skill which a real pleasure”. The renewed interest in cooking is primarily a response to the level obesity in Britain which is among the highest in Europe, and according to government figures half of all Britons will be obese in 25 years if current trends are not stopped

Chances are that your next CEO will be a she and your next congressman will be a congresswoman. After thousands of years of oppression, women across the world are occupying key positions in all spheres of society. The ever-evolving human desire drives the development of men and women alike. Over the past 60 years, we have witnessed a conspicuous change in women’s desire. Women wish to be less and less involved in household management and child care, and are increasingly expanding their involvement in other areas of society. At the same time, the world is pushing towards greater equality, and women assume roles and responsibilities previously only filled by men. Technology also plays a significant role in helping free up women’s time. Just as diapers and baby formula were a tremendous help for mothers, emerging robotics and artificial intelligence solutions will reduce the burden of household management to a level we have never seen. As the world becomes more interdependent, it demands the intervention of women, as though it were asking them to put their unique qualities into practice. A woman’s character is much more responsible, stable and consistent. She is capable of absorbing many changes and coping with long-term challenges — a quality that comes from her natural ability to carry an embryo and develop life within her. A man, on the other hand, is better at short-term moves. A woman is capable of holding onto a large number of tasks as well as carry them out successfully. A man, on the other hand, is more successful in linear processes aimed at a narrow goal. This is why most scientific breakthroughs, for example, manifest through the male brain. Men and women are also different in their attitude to failure in life. Figuratively speaking, a man can be as strong as iron — and yet one blow can break him. The woman is easier to bend — but like a flexible tree branch, she is much harder to break. The mutual completion of each other’s qualities is the key to building a healthy society in the new era. The integration of women in the leadership of society and other systems of human life is becoming necessary. The maternal qualities are expanding from the personal home to the global home. The female nature and drive to create a supportive and embracing environment will be expressed in society in creating healthy and proper conditions for bonding between people.

Facebook users spend an average of more than 15 hours a month on the social  networking site. While there are plenty who caution against such intensive use — and there are a number of studies detailing the harm Facebook could potentially cause — there also are lots of reports extolling the site’s virtues. As the social media giant prepares for its upcoming initial public offering, here are some ways Facebook just might be good for you.  Spending time on Facebook can help people relax, slow down their heart rate and decrease stress levels, according to researchers from the Massachusetts Institute of Technology and the University of Milan. In a study published earlier this year, researchers studied 30 students and found that a natural high was sparked when they were on the social media network that led to the relaxed heart rates and lower levels of stress and tension. In the study, the students were monitored in three situations: looking at panoramic landscapes, performing complicated mathematical equations and using Facebook. While the first situation was the most relaxing to students and the math problems were the most stressful, the time on Facebook uncovered high levels of attractiveness and arousal. The findings support the researchers’ hypothesis that Facebook’s success, as well as that of other social media networks, correlates to the specific positive mental and physical state users experience.  While many may argue that social media networks only distract employees, research shows the opposite may be true. Research from Keas.com found that a 10-minute Facebook break makes employees happier, healthier and more productive. The study examined workers in three groups: one that was allowed no breaks, one that was allowed to do anything but use the Internet and one that was allowed 10 minutes to use the Internet and Facebook. The Facebook group was found to be 16 percent more productive than the group that was not allowed to use the Internet and nearly 40 percent more productive than the group that was allowed no breaks. “Short and unobtrusive breaks, such as a quick surf on the Internet, enables the mind to rest itself, leading to a higher net total concentration for a day’s work, and as a result, increased productivity,” said Brent Coker of the department of management and marketing at the University of Melbourne in Australia.  Facebook is also in the business of matchmaking. Research shows that nearly 60 percent of singles will friend someone new on Facebook after meeting them in person. If they like what they see, 25 percent are likely to contact their new love interest via Facebook. Once the courting is over, nearly 40 percent of those social networking adults will update their relationship status on Facebook, with just 24 percent telling their friends first. Facebook use between couples will continue through the dating process, the research shows. Throughout the day, 79 percent of couples said they send partners Facebook messages or chat on the social network. In addition, more than 60 percent would post romantic messages on their significant other’s Facebook wall. When the relationship ends, more than half of those surveyed immediately update their status to single, which automatically sends out a notification to their friend list to start the dating cycle over again
8. Which of the following could best describe the tone of the passage?

Read the following passage and choose the best answer (A, B, C, D):
There are many types of family systems around the world. In North America and  northern Europe, the nuclear family (with two generations - a father, a mother and one or more children) is often seen as the most typical. In contrast, in most other parts of the world, extended families, which include other family members such as grandparents, aunts, uncles and cousins, are seen as the norm.  The common view is that the nuclear family has become the norm in many Western societies as a result of industrialization and urbanization. This trend began in the late eighteenth and nineteenth centuries, when people were forced to move to cities to find work in the factories that sprang up during the Industrial Revolution. In the twentieth century, greater industrialization resulted in even more people leaving their large extended families. Urbanization also meant that people lived in much smaller houses, which were not big enough for an extended family.  The trend towards nuclear families meant that many of the duties and responsibilities of a family, such as providing food and shelter, cleaning the home, preparing the food, caring for children and their education, and caring for the sick and elderly are no longer shared among the members of the extended family. The parents (or parent) now have to do this, with some help from the state. However, this is the price that people pay for the higher standard of living that may come from living in a city.  We may think we know what we mean by a ‘nuclear’ family and an extended family, but reality is more complicated than most people believe. Most nuclear families are part of extended families: children have grandparents and, in many cases, aunts, uncles and cousins as well. Part of what makes them ‘nuclear’ is that they live in their own separate household, but it is not the whole story. In Greece or Italy, for example, a nuclear family may live in its own flat, but the extended family may live in the same apartment block or in the same street and family members see each other and even eat together every day. There is at least one more factor to consider. Family members may be separated from each other by geographical distance, but they may have close emotional ties. Even in North America and northern Europe, grandparents usually have close bonds with their grandchildren, and families often travel long distances so that they can see each other. Grandparents often help their adult children, for example, by cooking and looking after their children in emergencies. In the same way, when their parents become too old to live on their own, adult children may take them into their own homes. As a result, they turn their nuclear family into an extended family.  The structure of families changes over time. The effects of urbanization and industrialization are enormous, but they are not the only reasons for the changes. People marry, have children, become widowed, divorce and die. Children grow up and adults grow old. Nuclear families become extended families and extended families become nuclear families. Family ties stay strong or become weak. One thing is certain: in a changing world, the family will continue to change, but ultimately, it is likely to continue to be the basic unit of society

Sophia is a humanoid robot developed by Hong Kong-based company Hanson Robotics. She has been designed to learn and adapt to human behavior and work with humans, and has been interviewed around the world. In October 2017, she became a Saudi Arabian citizen, the first robot to receive citizenship of a country. According to herself, Sophia was activated on April 19, 2015. She is modeled after actress Audrey Hepbum,and is known for her human-like appearance and behavior compared to previous robotic variants. According to manufacturer, David Hanson, Sophia has artificial intelligence, visual data processing and facial recognition. Sophia also imitates human gestures and facial expressions and is able to answer certain questions and to make simple conversations on predefined topics (e.g. on the weather). The robot uses voice recognition technology from Alphabet Inc. (parent company of Google) and is designed to get smarter over time. Sophia’s intelligence software is designed by SingularityNET. The AI program analyses conversations and extracts data that allows her to improve responses in the future. It is conceptually similar to the computer program ELIZA, which was one of the first attempts at simulating a human conversation. Hanson designed Sophia to be a suitable companion for the elderly at nursing homes, or to help crowds at large events or parks. He hopes that she can ultimately interact with other humans sufficiently to gain social skills. Sophia has been interviewed in the same manner as a human, striking up conversations with hosts. Some replies have been nonsensical, while others have been impressive, such as lengthy discussions with Charlie Rose on 60 Minutes. In a piece for CNBC, when the interviewer expressed concerns about robot behavior, Sophia joked that he had “been reading too much Elon Musk, and watching too many Hollywood movies”. Musk tweeted that Sophia could watch The Godfather and suggested “What’s the worst that could happen?”. On October 11, 2017, Sophia was introduced to the United Nations with a brief conversation with the United Nations Deputy Secretary-General, Amina J. Mohammed. On October 25, at the Future Investment Summit in Riyadh, she was granted Saudi Arabian citizenship, becoming the first robot ever to have a nationality. This attracted controversy as some commentators wondered if this implied that Sophia could vote or marry, or whether a deliberate system shutdown could be considered murder. Social media users used Sophia’s citizenship to criticize Saudi Arabia’s human rights record.

Pick any day in the Piazza del Duomo in the Italian city of Pisa, and you will  undoubtedly spot a bunch of tourists posing for the same photo: hands outstretched towards the cathedral’s conspicuously tilting bell tower, as if they are supporting it with their sheer strength. The so-called Leaning Tower of Pisa is one of the most famous buildings in the world, although maybe not for the reasons its original architects would have wanted.  In 1173, construction began on a white marble bell tower for the cathedral complex in Pisa, located between the Arno and Serchio rivers in Tuscany, central Italy. By the time builders had finished the third of eight planned stories about five years later, the tower’s foundation had begun to settle unevenly on the ground beneath it, a dense mixture of clay, sand and shells. As a result, the structure had begun to tilt visibly toward the south. Shortly after that, war broke out between Pisa and Genoa, another Italian city-state, halting construction for nearly a century. This delay allowed the foundation to settle further, likely prevented the bell tower’s premature collapse.  When construction resumed, chief engineer Giovanni di Simone tried to compensate for the lean by adding extra masonry to the short side, but the additional weight caused the structure to tilt even further. The tower was officially completed around 1370, but its lean only increased over the next six centuries, becoming an integral part of the monument’s quirky appeal. Despite various attempts to reinforce it, Pisa’s tower continued to subside at a rate of some 0.05 inches per year, placing it in increasing danger of collapse. By 1990, it was leaning 5.5 degrees (or some 15 feet) from the perpendicular–the most extreme angle yet. That year, the monument was closed to visitors and the bells removed as engineers started extensive reparations to stabilize it. By siphoning earth from beneath and adding counterweights to the tower’s north end, they were able to reduce the lean to 13.5 feet, or 4.0 degrees from perpendicular. The straightening continued after the tower reopened in 2001, and in 2008 sensors showed the subsiding motion had stopped, after a total improvement of some 19 inches. Engineers now believe the Leaning Tower of Pisa will remain stable for some 200 years, barring an earthquake or other unpredictable disaster.

Read the following passage and choose the best answer (A, B, C, D):
According to the report, we can expect some pretty remarkable changes to our homes  and our personal spaces, overlooked things that make up so much of our daily routine. As human populations soar, our cities and homes will have to adapt; interior living spaces will change as a cloud changes, easily reconfigured and rearranged to suit our fickle tastes, or accommodate different purposes.  Imagine walls and floors made of a malleable “skin,” and embedded with tiny sensors and actuators so that the shape and size of living spaces can quickly change, or even be divided into smaller rooms; imagine fully programmable “smart homes” that can be controlled remotely, and provide feedback to their owners - yes, there’ll even be an app for that.  Virtual decorations will alter with changing tastes, moods and whims; and the entire interior surface of the home will be implanted with LED technology - television screens and computer displays will form and unform in any room, as needed. Even our furniture will be adaptable, molding to custom fit our bodies, responding to changes in posture, or disappearing altogether when not needed.  It will be the ultimate evolution of the “Internet of Things.” Misplaced something? Can’t find your keys? No problem. Just use an online search function to find it. Hate the color of that accent wall? Delete it. Need more storage space? Watch new shelves appear, as if by magic. And the amenities are fantastic. Every home will come standard with a 3D printer; they’ll be able to churn out just about anything you could wish, using downloadable patterns, probably including even complex electronic devices. They may even print out your meals, designed and programmed by the world’s master chefs.  Walk-in “medical pods,” meanwhile, will contribute to the decentralization of healthcare - their imaging sensors will diagnose your ills and, for the more easily treatable maladies, dispense drugs, inject antibiotics, and recommend health regimens. It may even be possible to undergo remote, robot-mediated surgery, in the comfort of your own home.  This barely scratches the surface. Imagine homes whose very building material is salted with dormant limestone-producing bacteria, which awaken upon contact with moisture and repair any cracks or structural damage.  There will be “digestion tanks” full of anaerobic bacteria, to dispose of our waste; and our homes will produce, store, and reuse their own energy, using “microbial fuel cell stacks” and more efficient solar panels to generate electricity, and power-banks like the Tesla power wall to store it against future use. Personal homes will be almost fully independent of a dangerously overtaxed energy grid.  One hundred years in the future, our houses will be, in almost all respects, semiliving, artificial organisms - closed systems with a metabolism, sensory apparatus, immune response, and an approximation to a nervous system. We’ll be living in homes that are practically alive.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.

The poaching crisis wiping out Africa's elephants is costing the continent's economies millions in lost tourism revenue, according to a new study. Researchers looked at visitor and elephant data across 25 countries, and modeled financial losses from fewer visitors in protected areas due to the illegal wildlife trade, which has caused elephant numbers to plummet by more than 100,000 in the last decade. (A)

The study team combined visitor numbers across 164 protected areas in 25 countries in forest and savannah elephants, and elephant population data from 2009 to 2013, to reach a “per elephant" value in terms of tourism income.

They concluded that Africa was most likely losing $26m in tourism revenue a year. (B) Around $9m of that is lost from tourists' direct spending, such as staying at hotels and buying crafts, with the rest through indirect value in the economy such as farmers and other suppliers supporting the tourist industry.

The study, published in the journal Nature Communications, found that in most cases the revenue losses were higher than paying for stronger anti-poaching measures to keep elephant populations stable. (C) Dr. Robin Naidoo, the paper's lead author and , senior conservation wildlife scientist at WWF and his team found. In the case of central Africa's forest elephants, which are harder for tourists to see and therefore attract fewer visitors, the costs of protecting them exceed the benefits from tourism. Demand from south-east Asia has seen the price of ivory triple since 2009 and it is estimated that one elephant is killed every 15 minutes. (D) Corruption, a lack of resources, and, most importantly, increasingly sophisticated poachers have hamstrung African countries' efforts to stem the trade.

Naidoo said that the research was not suggesting economic issues should be the only consideration when protecting elephants, but framing the poaching crisis as a financial one could motivate African governments and communities.

“It gives an additional reason for some groups of people, who may not necessarily be motivated by intrinsic reasons for conversation, to engage with biodiversity conservation. It makes it clear to them that it's not just in the best interests of the world to conserve this stuff, but tangible reasons for a whole different group," he said.

With 13,000 floral species and over 15,000 faunal species, three newly discovered big animal species, and a ratio of country/world species of 6.3%. Vietnam has enormous tourismparticularly ecotourism-potential. In fact, since 1986, when Renovation Reforms began the shift from a centrally planned to a socialist-oriented market, or multi-sectoral, economy, tourism has been an sector of primary concern to the government. In May 1995, the prime minister of Vietnam approved a master plan of tourism development for the period 1995- 2010. In February 1999, the state decree on tourism was part of the socio-economic development strategy for the period 2001-2010 approved at the IX National Congress of the Party: “Tourism development has become a spearhead economic industry indeed. It is necessary to improve the quality and effectiveness of tourism activities, bringing into full play the natural conditions, and cultural and historical tradition to meet the domestic and international demand for tourism and to catch up with tourism development in the region” (Document of the IX National Congress 2001). Tourism has so far brought great benefits to the economy, but it has also contributed to environmental degradation, especially biodiversity deterioration. Thus, the concept of “sustainable development”-development which meets the needs of the present without compromising the ability of future generations to meet their own needs - must be factored into tourism development. This consideration is reflected in the term “ecotourism,” which is referred to variously as ecological or environmental tourism, nature or green tourism, sustainable or responsible tourism. Ecotourism involves travel to relatively undisturbed natural areas with the specific object of studying, admiring, and enjoying scenery, plants, and animals, as well as any cultural features found in these areas. It is distinguished from mass or resort tourism by its lower impact on the environment, lower infrastructure requirements, and its role in educating tourists about natural environments and cultural values. Fully aware of its significance, the government of Vietnam has prioritized ecotourism in its strategy for tourism development to ensure both sustainability and economic benefits. Though ecotourism in Vietnam is at a beginning stage of development, it is expected to grow strongly through support from government and international organizations.

Human’s avarice for ivory has resulted in thousands of unfathomable elephant atrocities and senseless suffering that has pushed the species to the brink of extinction. In 2015, the U.S. and China announced they will work together to enact a near complete ban on the import and export of ivory. As an industry that has largely been driven by China and, if substantiated, these claims could be a ray of light for one of the most endangered animals in the kingdom. However, as the famous saying goes, “for every action, there is an equal and opposite reaction.” With the worldwide attention on elephant ivory, hippo teeth, which can grow up to three-feet-long, have become the next target. Since the United Nations Convention on International Trade in Endangered Species officially imposed a ban on ivory trading in 1990, about 30,000 pounds per year of hippo teeth have been exported from Africa. On a recent trip to Kenya, I had the unfortunate displeasure of meeting these facts face-to-face. On the banks of the Mara River, the infamous transient point of the great wildebeest migration, I met a Conservancy Ranger, a local Kenyan, named Ivan. He led me along a narrow path above the riverbed to view pods of hippos. They clumped together in the river, every few minutes lifting their heads above the waterline to welcome my arrival. Despite their label as one of the most dangerous animals in Africa, they were playful to watch. Their tiny ears and eyes would appear from the murky river and then, with a splash, they would disappear. The river is everything to the hippo, Ivan explained, it is their lifeline. The only real time they leave the river is during their nightly ritual of traveling to nearby plains to consume grasses. Contrary to their aggressiveness, they are vegetarians. As we neared the end of our trek, we reached the Mara Bridge, spanning the divide between Kenya and Tanzania. An undeniable stench filled the air. Our gaze fell to the water beneath the structure, and as if to mark the metaphorical significance of the passage, lay a poached hippo. It had been killed the previous night, probably as it grazed unsuspectingly under the cover of darkness. They had found spear punctures in its body, and its teeth were missing. It had somehow, in unthinkable pain, made its way back to the river, its home, to die.

Stonehenge, the prehistoric stone circle in southern England, is one of the most distinctive and mysterious monuments in the world. The monument, which attracted more than one and a half million visitors last year, is thought to be up to 5,000 years old, and the heaviest stone weighs 38 tons. No one really knows how the stones got there, or the reason they look the way they do – but a piece removed from one of the stones six decades ago could bring some answers. At first glance, the new “discovery” - a cylinder of rock - might look unremarkable. But for Lewis and Robin Phillips, it meant one thing: their dad, Robert. In 1958, Robert Phillips worked on a major restoration project commissioned by the British government. The goal was to make the monument safer, and help historians better understand what Stonehenge was and why it was there. The team drilled through the largest of the sarsen rocks, removing three stone cores. Robert Phillips was gifted one as a souvenir. At the time, the core sample was considered to be “waste material,” Lewis said. “I think that the standards of the day, in conservation, were a bit different to what they are now,” Robert added. Six decades later, Robert - who’s now in his 90s - asked his sons to return the “waste material.” But what had become a family heirloom for the Phillips’ was “the Holy Grail” of Stonehenge for geologists, according to Susan Greaney, an archaeologist at English Heritage. “When the Phillips family first got in touch with us, we had no idea that this existed,” Greaney said. “We’d just assumed that they’d been thrown away.” In 1958, samples like this couldn’t provide much information - but now, Greaney added, it can help archaeologists understand where the stones were from and how they were transported. It could even provide clues to one of the biggest questions: why move all these rocks to one location? Right now, “we don’t know” is the answer to that, Greaney said. "We think this is a prehistoric temple. It’s aligned with the movements of the sun, so we think it’s some kind of ceremonial space. But exactly what the stones mean, why they built them in this way and set them up in the way we see today, there are lots of mysteries about Stonehenge that we have yet to get to the bottom of.
