Reading bank 4 © Oxford University Press Reading bank Electronic money We’ve used home computers and the Internet for banking since the 1990s. Is the ‘mobile wallet’ going to replace cash? It’s now possible to pay for things in a shop by standing near the till and tapping an app on your mobile phone. ‘Wave-and-pay’ technology allows electronic devices to communicate when they are near each other. Shoppers can add money to their phones electronically, and shopkeepers’ devices can take money in exchange for goods. Soon, some experts say, all mobile phones will have this technology. Imagine the convenience. Most of us carry a mobile phone, and with electronic money, we would never worry about having enough cash. We could top up the phone’s ‘wallet’ online, from a bank account, and never think about having the correct change for the bus. Using the phone’s software, parents could give their kids money that could be spent only on certain things – books and pencils, for example, but not sweets or soft drinks. But don’t give up on cash yet. Very few phones have the wave-and-pay computer chip, and most shops don’t have wave-and-pay readers. Security is also an issue. Some experts warn that thieves may be able to steal your money simply by standing near you. Wave-and-pay doesn’t always use a personal identification number (PIN). A hidden reader in a thief ’s pocket might be able to take your money without you knowing. We won’t give up cash this year or next, but some experts believe that by 2030, all money will be electronic. 1 Digital technology 1 How often do you use each method of payment (in shops, to pay rent or bills, to pay for services)? 1 Cash 2 Cheque 3 Credit or debit card 4 Electronic bank transfer 2 Read the text. Mark each statement T (true) or F (false). 1 Wave-and-pay is a way for shoppers to buy things. 2 Wave-and-pay uses technology that already exists in all mobile phones. 3 Shoppers can use wave-and-pay to transfer money directly from their bank to the shop’s till. 4 The technology might easily allow parents to control their kids’ spending. 5 Wave-and-pay is even safer than cash because no one can steal it. 6 Paper money and coins probably won’t be used five years from now. 3 Answer the questions. 1 Do you use wave-and-pay now?

It’s important to work out the best routes for the pipes, ducts, and cables involved as this can affect the cost of the work considerably. I like being out and about, not stuck in an office, and this job involves a lot of travelling. I also like the contact with customers. I work for a company which installs central heating and air- conditioning systems. We do everything: planning, installing, testing, and commissioning. Get the highest qualifications you can when you’re at college. It’s better to do it at that stage in life than try to catch up later. Keep up your professional training when you’re in the job. Move to a company large enough to offer good promotion prospects. When you switch on and it all works perfectly. Working in confined spaces, for example under floors or in roof spaces where there isn’t a lot of headroom. Five years. Reading bank 6 © Oxford University Press How bioengineers apply biology, physics, chemistry, and mathematics to real-world problems Biological engineering (usually shortened to bioengineering) is the practice of working with, and sometimes changing, the natural world. But what does that mean? Here are some projects bioengineers are working on today. Smart medicine We usually take medicine after we realize we’re ill. Bioengineers are working on tiny ‘intelligent’ capsules (small containers) that can be placed inside the human body. At the first sign of illness – usually a small chemical change – a capsule could release drugs into the human body and fight the illness. At the moment, this is very specialized technology for astronauts. But one day, smart medicine may be available to everyone. Carbon capture Climate change is a big issue, and most experts agree that carbon dioxide (CO2) in the atmosphere is a major problem. While governments argue about the best ways to control CO2 production, bioengineers are working on technological solutions. One solution is to remove CO2 from emissions as they’re being produced by cars and factories. This could be done by mixing the CO2 with other chemicals. Another possibility is to create huge carbon capture stations. They would look like nuclear power plants, but they would remove large amounts of CO2 from the surrounding air. Super wheat The world’s population has reached seven billion people and is still growing. Agriculture – growing plants and animals to feed people – requires huge amounts of land, water, and other resources. Experts believe that as the population grows, it will become more difficult to feed everyone. Bioengineers are working on ways to improve basic food plants such as wheat. How? They believe they can improve the efficiency of photosynthesis – the process of plants turning the Sun’s energy into food for the plant. This increases the grain yield – the amount of edible wheat produced – without increasing the area of land needed. If they can do this, farmers will be able to provide more food without using more resources. 3 Biology 1 Answer the questions. 1 What do you think are the world’s top three problems today? 2 Can you think of possible solutions to any of the problems? 3 Can you guess what a bioengineer does? 2 Compare your answers with the information given in the text. 3 Now read the text again and choose the best phrase to complete each sentence. 1 Smart medicine . a improves the function of the brain b detects and treats illness c improves skin appearance 2 Carbon capture may . a help governments catch criminals b become a useful energy source c help reduce global warming 3 Super wheat will . a make agriculture more efficient b help reduce global population c turn plants into a clean fuel source for cars Reading bank 7 © Oxford University Press 4 Chemistry 1 Make a list of three materials that you think are very important in the modern world. List ways they are used. Example paper – used for books, newspapers, magazines, and shopping bags. 2 Read the text and find the answers to these questions. 1 What everyday item uses graphite? 2 In addition to graphite, what other two substances does the text name that are made entirely from carbon atoms? 3 Who gave graphene its name? 4 What everyday item helped two physicists win a Nobel Prize? 5 What two materials does graphene perform better than? 6 What three products might use graphene? 3 When it was first invented, glass must also have been a ‘miracle material’. How many everyday things can you think of that include glass? Graphene – a miracle material Graphite has been used in pencils for hundreds ofyears. But could it be the source of the next big breakthrough in materials science? Graphite is made entirely of carbon atoms – just as diamonds are. In diamonds, the atoms are arranged in a crystal structure that makes the material incredibly hard – the hardest substance in the world. By contrast, carbon atoms in graphite are arranged in flat layers. This makes graphite relatively soft. It also means that graphite can form very thin layers, such as when you make a mark on paper with a pencil. Hanns-Peter Boehm, a German chemist, first observed layers of graphite that were only one-atom thick in the 1960s. He named his discovery graphene. Other scientists studied and tried to produce graphene throughout the 1970s, 80s, 90s, and into the 2000s. A breakthrough finally came in 2004, when two physicists at Manchester University removed a single-atom-thick layer of graphene from a piece of graphite – using a piece of ordinary sticky tape. They received a Nobel Prize for their work. What’s so great about graphene? • Graphene sheets are 200 times harder than steel. • Graphene conducts electricity better than silicon. • It’s extremely thin and lightweight. What will we do with it? Here are some of the experts’ ideas: • Graphene could be used to replace silicon in computers’ logic circuits. • Incredibly strong fabrics or ‘smart clothing’ could be made with graphene. • Screens of gadgets such as smartphones could be made much stronger with graphene. Reading bank 8 © Oxford University Press What can you do with a degree in Mathematics? You probably know about accounting and teaching, but here are some maths jobs you may not have heard of … Computer security Computers are everywhere, and they contain our bank account information, credit card details, medical records, and other data we want to keep secret. How can we keep hackers from stealing this data? Cryptography is a field of mathematics that involves writing codes and finding ways to keep secrets. Governments and private companies employ cryptographers to keep computer data safe and secure. Atmospheric science and meteorology Global warming has become a big concern. Scientists use mathematical models to help them understand how the Earth’s complex environment systems might behave in the future. Meteorologists (weather experts) also use mathematical models when they’re predicting the weather for the next weekend or trying to understand what huge storm systems might do next. Biomathematics Doctors and medical researchers rely on experiments and observation to understand medication. They also use complex mathematics to understand drug data and to predict possible responses to medicines. Biomathematicians also apply mathematics to the understanding of the interaction of living things in biological systems. Business analysis Businesses usually want to improve their efficiency. But particularly in larger, more complicated businesses, it isn’t always easy to understand how systems really work. Mathematical analysis can be applied to many aspects of business (production processes, transportation and storage of products, worker efficiency) to help identify places where improvements can be made. Petroleum production From exploration to transport, use and environmental impact, mathematics is an incredibly useful tool in the energy industry. In addition to understanding the financial side of the business, mathematics is used by geologists (experts in rocks, soil, and other features of land) to predict where oil might be located, how much there is, and how long it will last. Mathematics is also used to predict what may happen as oil becomes more difficult to find. 5 Mathematics 1 Answer the questions. 1 How often do you use mathematics? 2 What do you use mathematics for? 3 Can you name any jobs that require very strong mathematical ability? 2 Read the text.

Experts say that we need to make the best use of technology to make these cities good places to live. So … fast forward to 2050, and what do we see? Green roofs Most buildings in the smart city of 2050 have plants on the roof. Plants help keep the air clean, and they reduce flooding problems when heavy rain falls. They also absorb heat, which keeps cities in warm climates cooler. Some people grow fruit and vegetables for themselves, too. Grey water The smart city of 2050 wastes nothing. Rainwater is collected and used on gardens. Grey water – water from showers and from washing up – is recycled for rooftop plants and is also used for flushing toilets. Purifying water uses a lot of energy, so using grey water saves both water and energy. Clever waste management There are no lorries collecting rubbish in the smart city. This helps reduce traffic on the roads. All waste travels from homes and businesses in a system of pressurised pipes. Some of the waste is used to produce methane gas, which is used for energy production. Green power In addition to the power generated using methane gas, wind and solar generation also powers the smart city. Computers monitor power use in the entire city and the electric power grid can respond to the need for power at any moment. When a lot of power is needed, the system can supply it, but when little power is needed, parts of the system shut down. This reduces energy waste. Intelligent traffic management Every car in the smart city of 2050 has a ‘smart tag’ number plate. Sensors in the road track every vehicle and control the flow of traffic. If a road is completely empty, the traffic signals are turned off to conserve energy. Smart homes Research shows that when people can see how much energy they’re using, they limit their energy use. The smart home of 2050 has an energy control panel. People can monitor their energy use and control heating and lighting. 6 Technology and society 1 Answer the questions. 1 What are the biggest problems in cities today? Think of things that make them difficult or uncomfortable to live in, or ways in which cities harm the environment. 2 What rules or arrangements has your town or city made to help the environment? 3 Can you think of things that cities – or people living in cities – could do to use energy more wisely? 2 Read the text. Underline the correct answer. 1 The article is about cities of today / the future. 2 Most buildings have solar panels / plants on the roof. 3 Water / Plastic is reused and recycled. 4 Some waste is used to produce energy / feed plants. 5 The electric power grid / waste management system is controlled by computers. 6 Cars aren’t allowed / are carefully monitored in the smart city of 2050. 7 People are / aren’t allowed to control their own energy use, because this tends to save energy. 3 Is your city like the smart city of 2050 in any way? Do you think that by 2050, it will be a smart city?

Why? / Why not? Designing for performance: A high-altitude safety suit How astronauts, pilots, and space tourists dress for success In 1960, US Air Force pilot Joe Kittinger used a balloon to travel more than 31 kilometres above the surface of the Earth. From that altitude, he jumped and fell for four and a half minutes, reaching a speed of 988 kilometres per hour before opening his parachute at 5,500 metres above the Earth. In one day, he set the record for the highest balloon flight, highest parachute jump, longest free fall, and fastest human fall. As humans were approaching the possibility of space flight (the first space flight was on 12 April 1961) aerospace doctors wanted to understand the effects of very high altitudes on the human body, and wanted to know if people could jump out of spacecraft high in the Earth’s atmosphere in case of emergency. Amazingly, Kittinger’s record wasn’t broken until 14 October 2012, when an Austrian skydiver, Felix Baumgartner, made a 39,045 metre jump. What are the design challenges of making a suit that can survive a fall from the edge of space? Pressure In the stratosphere – the part of the atmosphere where Kittinger began his fall – the air pressure is about 1/1,000th of the pressure at sea level and contains very little air. To avoid altitude sickness, the safety suit must have a pressure inside that is similar to the pressure nearer the Earth’s surface. The suit is tightly sealed, and special containers of gas are used to maintain a comfortable pressure. Oxygen supply The suit has two tanks of 100% oxygen (not air, which is about 78% nitrogen). Breathing pure oxygen removes nitrogen gas from the skydiver’s body. This is because during changes in pressure, nitrogen bubbles in the body can cause serious medical problems. Temperature control The temperature outside the suit is between –68 ºC and 38 ºC. The suit is made of a super-insulating material that keeps the inside of the suit comfortable even as the outside temperature changes rapidly. Parachute The main parachute opens automatically, at about 750 metres above the Earth. A sensor detects the atmospheric pressure at that altitude. This means that if the skydiver is injured or unconscious, a safe landing is still possible. Communications In addition to a two-way radio, the suit includes instruments that measure the skydiver’s breathing, heart rate, speed, and angle of the body as it falls. The suit also includes a video camera.

High-tech sportswear Sports companies are always trying to develop new sportswear that will allow athletes to perform more efficiently. Recent developments include: PReCool veST Nike has developed a vest which holds ice packs in its lining. It is designed for athletes who compete in marathons and other long distance races. Wearing it for one hour before the race will reduce the body temperature by 19%, and therefore reduces the risk of heat injury. faSTSkin Speedo has designed a swimsuit which it claims is the world’s fastest. The designers have worked with an expert on sharks – famously fast swimmers of the fish world. The material copies features of Sharkskin and is designed to reduce drag. The makers say it can increase performance by up to 4%. PoWeR SoCkS Adidas produces knee-length socks for runners which are designed to reduce leg fatigue. The socks save energy by compressing the muscles in the legs. This prevents the muscles vibrating each time the runner’s foot hits the ground. The vibration is a waste of energy. SWifT SuiT Adidas has designed an aerodynamic head-to-ankle suit for sprinters, cyclists, rowers, and ice-skaters. It keeps athletes cool and reduces drag. The designer claims it gives a ten-centimetre advantage in a 100-metre sprint. STRaPleSS goggleS For swimmers, Nike has developed featherweight carbon goggles without straps. Each lens is stuck to the eye socket with medicalglue. Having no straps, the goggles produce less drag than ordinary goggles.

It has a very simple design and uses inexpensive parts. The United Nations estimates that 24,000 people die each year because of mines. The Dervish has three wheels. Each wheel has steel teeth to create more pressure. When the teeth pass over a mine, it explodes. The wheels can explode around 1,500 mines before they have to be changed. A motorbike engine powers the Dervish. The device rotates. As each wheel passes a certain point in the rotation, it slows down. This makes the machine advance in tight circles, about 30 mm apart.

The iris is the coloured ring round the central part of your eye. Each one is different, which makes it perfect for security systems such as iris scanning. First, your iris is scanned and the information converted to a digital file which is stored in a database. This process takes about three minutes. When you go to a high-security area, you simply look at a camera which scans your iris. The result is compared with your database entry. It takes just over a second to complete the check. The system is used at airports to speed passengers through passport control and to control entry to restricted areas. Some banks use it at ATM machines instead of PINs. Apart from the speed, the advantage is that users don’t need to remember a password or key. The system can handle users wearing glasses, contact lenses, and also changes to the eye as people age. So far, it’s foolproof. The advanced taser gun is an electric stun gun which allows police to deal with violent people without causing injury or death. It has a laser sight to make sure the suspect is properly targeted. It uses a compressed air cartridge to fire two darts at the suspect. The darts pull behind them fine electric cable. They can penetrate the thickest clothing, up to 5 centimetres, at a range of 6.4 metres. When the darts hit someone, the gun delivers a 50,000 volt shock for five seconds. The shock causes temporary paralysis. Taser waves – electrical signals – cause the suspect’s muscles to contract. The guns contain a microchip which records the date and time of each firing.

Hybrid cars A hybrid-electric vehicle (HEV) has both a petrol engine and an electric motor. The petrol engine is the main power source. It is smaller and lighter than the engines of conventional cars. The electric motor provides extra power when needed. In some HEVs, it is connected to the wheels by the same transmission. In addition to a fuel tank, the HEV carries a pack of advanced batteries. There is also a processor which decides when to use the motor and engine. When the car is running at a constant speed – cruising – the petrol engine provides all the power required. For overtaking, hill climbing, and accelerating from a standstill, the electric motor provides extra power. In some cars, the motor also provides power for low-speed cruising, as petrol engines are least efficient in these conditions. HEVs use regenerative braking. When the driver brakes, the resistance of the motor helps to slow down the car. At the same time, the energy from the wheels turns the motor which then functions as a generator, producing electricity to recharge the batteries. When the batteries are low, the petrol engine also drives the generator. HEVs have automatic start / shutoff. The petrol engine shuts off when the car comes to a stop. When the driver presses the accelerator, the motor instantly starts the engine again. No energy is wasted from idling when the car is stopped. HEVs are more efficient and pollute less than cars with only petrol engines. They do not require special fuel like hydrogen cars and, unlike electric cars, they do not need to be plugged in overnight to recharge the batteries. However, they are heavy because of the weight of the batteries. petrol engine battery driving wheels electric motor Reading bank 17 © Oxford University Press 13 High living: skyscrapers 1 You need to be able to travel quickly up and down skyscrapers. Look at the diagram of a lift system on the next page and answer these questions. 1 What is the counterweight for? 2 What are the guide rails for? 3 What are the safety features? 2 Now read the text to check and to add to your answers. 3 Read the text again and find the answers to these questions. 1 What does the microprocessor do? 2 Why is travelling in a lift one of the safest journeys you can take? The development of tall buildings and lifts go together. The first lifts, or ‘elevators’ in American English, consisted of a platform suspended from a rope which passed over a pulley at the top of the building. If the rope broke, the platform fell to the ground. In 1852, Elisha Otis invented the first safety lift. If the rope broke, a brake was applied automatically which locked the platform in place between guide rails. Today the Otis company is the largest supplier of lifts in the world. Most lifts today are roped lifts. The car runs between vertical guide rails which keep it steady and act as a safety device. Steel ropes, or cables, attached to the roof of the car pass over a pulley, called the drive sheave, which is turned by an electric motor. The other endof the cable is attached to a counterweight. This matches the weight of a car with an average load of passengers. The counterweight saves energy. Its weight helps to raise the car. In the same way, the weight of the car when it descends helps to raise the counterweight. For the most part, the motor only has to overcome friction. Lifts are controlled by a microprocessor in the machine room. This logs all passenger calls and monitors the number of passengers travelling from floor to floor, the position of any car in the system, and its speed. It can direct passengers to the car which will get them to their destination fastest, and will prevent any car which is overloaded from moving. Lifts have many safety devices which make it virtually impossible for an accident to happen. The cables consist of up to eight steel ropes wound together. Each one is strong enough to support the car. If the car starts to run too quickly, a ‘governor’, or safety brake, locks the car to the guide rails. Doors on each floor ensure that no one can fall down an open lift shaft. Doors on the car ensure that no passenger can be injured by contact with the shaft. The car cannot move until both sets of doors are closed. Finally, at the bottom of the shaft there are large shock absorbers, or buffers, to cushion the impact of any fall. All these things combined make travelling in a lift one of the safest journeys you can take!

So what’s next for touch screens? Today’s touch screens are made of glass. They’re flat like glass, and a bit cool like glass. If you’re used to typing on a traditional keyboard, you may think touch screen typing isn’t as nice. You don’t feel a click when you press a key (though you can choose to hear one). Many people say this is a small problem compared with the great benefits of touch screen keyboards: they’re lightweight, easy-to-clean, and they disappear when you aren’t using them. Touch screens are here to stay, but researchers at a company called Tactus say that people like to feel things more – that while touch screens are beautiful, real buttons are more user-friendly. These researchers are working to create ‘tactile’ touch screens – flat screens that can create raised buttons that users can temporarily feel. Small areas of the plastic screen ‘inflate’ and then return to a flat surface. This sort of screen is still probably a few years away, but research and development teams are already working hard at producing it. The feeling of buttons may be just the beginning. Another team of researchers has announced a technology called REVEL that can create not only the feeling of a raised area, but also different textures, for example rough wood or smooth cloth. At the moment, this technology works only when the finger is moved across the screen. In this case, the screen itself doesn’t change. It works by attaching a small electrical signal generator to a person’s chair, or perhaps the inside of their shoe. When they touch certain objects, a small electrical signal travels through the body, and a small electrostatic force is created where the finger touches the screen. This creates the illusion of feeling. These two technologies will be useful not only in smartphones and tablets, but also in games, navigation equipment, and controls on electrical appliances. So, what’s the future of the touch screen? It turns out it may be something you can feel, like an old-fashioned keyboard. 14 information technology 1 Do you own or have you used any gadgets with a touch screen?

It was manufactured on 22 September’. With a built-in RFID reader, the fridge knows what’s inside it at all times. You can set the fridge to send you an alert when there’s only one carton of milk left. The smart fridge can also be programmed to keep a list of products that you need, and place an order with the supermarket for delivery when certain products are about to run out. An app on your smartphone allows you to check the contents of your fridge from anywhere. The smart fridge also communicates with the electrical power company. Some companies charge different rates for power at different times of day. The fridge receives signals from the power company when electricity rates are higher, and switches to a low- energy mode for brief periods. It’s easy to see the benefits of an Internet-ready fridge, but what about an Internet-ready washing machine? Korean appliance maker LG already produces one. If there’s a problem with the machine, it sends you a message with a full explanation. If you need to deal with particular stains in clothing, you can download a special wash cycle to solve the problem. The product line also includes an oven that can download recipes and cooking instructions, and will send you a message when a meal is cooked and is ready to be taken out of the oven. 15 Telecommunications 1 Have you heard of an Internet-ready fridge or Internet-ready washing machine?

What do you think these terms mean? a telemedicine b telecare c telesurgery 2 What sort of technology would be needed for each of the services described by these terms? 3 Who might benefit from these services? 2 Read the text to check your answers. Telemedicine is the application of Information Technology to medical care. It’s about providing medical support at a distance to people who have no access to a doctor. Using the Internet, satellite phones, video links, and digital cameras, patients, nurses, doctors, and others can obtain specialist help quickly. If passengers fall ill on an aircraft in flight, cabin crew can use a device called Vital Signs to measure blood pressure and other important signs. The data can then be transmitted to a doctor to interpret and provide advice on treatment. Medical images, such as X-rays or ultrasound scans, can be taken in one country and sent by broadband to a specialist in another for expert advice. Using a video link, nurses in a minor injuries clinic can call a specialist to examine difficult cases remotely. This is much cheaper than having a specialist available in the clinic. Telecare is a way of looking after vulnerable people, such as the elderly, at a distance. Sensors in their homes can detect falls, lack of activity, or even if food is removed from the refrigerator. Lack of movement triggers an alarm which alerts medical staff or relatives. Patients can wear monitors for recording their pulse and other signs. This can be sent via a telephone system to medical staff without the patient leaving home. Telesurgery was used in 2001 to allow a surgeon in New York to operate on a patient in France. The operation was carried out using a high-speed computer link and robotic tools in the French operating theatre. At this stage, such procedures are expensive, and a local surgeon has to be present in case the network link fails. In the future, however, telesurgery could be a life-saver for people living, working, or travelling remote from medical help.

Robots are very good at doing the same task in the same place over and over again. In factories and nuclear power stations, more than a million robots behave in this way every day. For robots to work with people, for example caring for the elderly, they need to be much more like humans. They need to be able to move like humans and adapt to new places. They also need to be more sensitive to touch and temperature. In humans, it is skin which provides important information on pressure and heat. Engineers at the University of Tokyo have developed an artificial skin for robots which is sensitive to pressure and temperature thanks to a large number of sensors. In addition, because it uses a mesh or net structure it can be stretched by up to 25% and still retain its sensitivity. This means it can be used to cover moving parts like joints. This E-skin opens the way for much more sensitive robots. For example, walking robots could use feedback from their feet to adjust to different surfaces. Robots in the future may be able to grasp different tools and use them as humans do. Domestic robots could pick up and bathe a baby without hurting it. They would also be less likely to damage themselves. A lot remains to be done. E-skin will provide much more information than the robot requires at any one time. Human brains can select only the important information. Before robots can act like humans, they need to have brains like humans.

The winning project is paid for and run by the WSTC and its partners in industry, and the winning applicant given further training and an apprenticeship. Here are three of this year’s entries: 18 Ways in to technology 1 Answer the questions. 1 What science and technology projects do you remember from your school days? 2 Do universities, companies or professional organizations in your country hold science or technology contests? If so, can you say anything about them? 3 If you could do any kind of research project in technology, what area of study would you choose? 2 Read the text. Mark each statement T (true) or F (false). 1 The WSTC is designed to help students pass exams. 2 Abdullah’s project could help make banks or government buildings safer from crime. 3 Lo-Chi’s project is designed to learn more about the bad behaviour of teenage boys. 4 The police might find some of Lo-Chi’s research results useful. 5 Michel’s project may help designers choose better paint for automobiles. 6 Michel’s project could improve the work environment of factory workers. 3 Which of the three projects would you most like to work on? Give reasons for your choice. Name: Abdullah Al Ansari Country: Saudi Arabia Course of study: Computer Science at Saudi Electronic University Research question: Are there connections between the sound of a person’s voice and the appearance of a person’s face? Where the idea came from: Watching TV, I started to wonder if people who look alike also sound the same. In some cases, it seems to be true. For example, my brother looks a lot like a famous newsreader, and their voices are similar. Practical application for this research: Some security systems use face recognition and voice recognition. If there are connections between faces and voices, then the system could detect people who are trying to fool it. Name: Lin Lo-Chi Country: Taiwan Course of study: Biology at National Taiwan University Research question: Why are some noises extremely unpleasant? Where the idea came from: When I hear the loud, squealing sound of the brakes on a lorry in the street, I hate it. It gives me a really bad feeling. But that’s strange, isn’t it? How can a sound cause a feeling – and such a strong feeling? Practical application for this research: If we understand more about the way sounds affect people, sounds could be used to help people have positive feelings. Also, ‘negative’ sounds could be used to break up crowds without hurting anyone. People would want to leave the area just because of the sound. Name: Michel Fabié Country: Belgium Course of study: Industrial Design at Lacambre Visual Arts School Research question: How does the colour of industrial machines affect the people who work with them? Where the idea came from: My brother recently bought a new car. He had a hard time choosing the colour, because he felt it was an expression of his personality. He felt it was an important decision because we have strong feelings about colour. Machines in factories are usually painted for safety– to make them highly visible – and also for protection of the machine, for example against rust. Practical application for this research: We might find that certain colours of machine paint make workers more alert, or perhaps less stressed. This could be a type of safety improvement, and also might improve productivity. Reading bank 24 © Oxford University Press What is permaculture? Permaculture is an approach to growing food. It aims to develop sustainable systems of agriculture. What are its main objectives? To take care of the Earth, to take care of the people, and to share the surplus – the food we grow beyond what we need. How does it meet those objectives? It aims to integrate agricultural systems with natural ecosystems as much as possible. In the world today, mainstream agriculture often requires the transportation of water and fertilizers long distances to make plants grow. Farm produce, in turn, is transported long distances to the consumer. Permaculture uses local resources to grow food for local consumers. Can you give us an example? Sure – Jordan. Jordan is a desert country with very little water. The soil is often poor and requires a lot of chemicals to grow fruits and vegetables. More than half of the available water in Jordan goes to agriculture, but demand for water has increased in the past ten to twenty years. It’s an incredibly tough place to grow food. At one farm in Jordan Valley, in the Kafrin area near the Dead Sea, they’re practising permaculture. The rainfall there is usually less than 150 mm per year, and it falls in two or three big storms. The soil is poor. 19 food and agriculture 1 Answer the questions. 1 Can you name any food plants that grow naturally in your country? 2 Do you know what foods are grown by farmers in your country? 3 Where does your country’s water come from? 2 Read the text.

Why? / Why not? Interview: Farming the desert Permaculture expert Karim Benzid talks about farming in a land with no water So first, let’s consider water. On this farm, they’ve set up a system to harvest rainwater when it does fall. They can store the water, and they use it in a way that reduces evaporation. It is fed to the plants in a steady drip. They also use some water from a well on the farm. So it’s local ground water. The plants are arranged so that the ones that need the most water are nearest to the source of the water. This reduces waste. Second, plants. The farm has olive trees and date palms – they both love the dry climate. These help shelter and protect other smaller plants – tomatoes, onions, garlic, and so on – from the Sun. In fact, the variety of plants is really important. In this area, farmers usually grow just one type of plant at a time. Which brings me to my third point, soil. Growing just one type of plant is terrible for the soil. Growing a variety of plants actually helps the soil. Also, the farm has chickens, sheep, ducks, and other animals. Waste from the animals, plus waste from the plants, is used to feed the soil. All of the energy and chemicals that the soil needs come from this waste material. There’s no need to use chemical fertilizers. Finally, consumption. The food grown on this farm is eaten locally. That means they don’t use energy bringing some foods into the area, and they don’t use energy transporting farm produce out of the area. It’s very efficient. Reading bank 25 © Oxford University Press 3-D printing Turning computer images into plastic models Since the 1990s, engineers have used 3-D printing to make models of complex designs. More recently, 3-D printing has been used to make objects for actual use, not just models. For example, doctors have used 3-D printing to make artificial body parts such as bones and joints. The process – called rapid prototyping – is still not widely used. But it’s becoming more common and techniques are being improved constantly. And now, three-dimensional printing at home is a reality. You buy and bring home a 3-D printer, download a design from the Internet, and create plastic objects in your own home. Here’s what you do: 1 Prepare the printer by loading it with plastic wire. The wire comes in ten colours. You also have to spread glue on the print platform. 2 Search the Internet for designs of objects that can be 3-D printed. Printer manufacturer Cubify has a wide selection at cubify.com, and others are available elsewhere. Designs include toys and games, jewellery, cups, lampshades, and many other things. 3 Using the 3-D printer’s software, convert the design to a set of instructions for building the object. The software works out any special supports that might be needed as the object is printed. 4 Press ‘Print’ and watch the printer create your design. 5 Let the plastic cool off, and enjoy your creation. So how does it work? The printer heats the plastic wire until it’s soft. The printer tip is heated to 300 °C, so when the plastic passes through it, it becomes even softer. The software tells the tip of the printer where to move to build up the object line-by-line. The printer tip can move up, down, and sideways, so it can go anywhere the software tells it to. The 3-D printer doesn’t make solid plastic objects. Instead, they are mostly hollow, with a kind of grid structure between the two walls of plastic. This makes the object strong and lightweight, and also reduces the amount of plastic needed to print it. There’s an important difference between 3-D printing in medicine and industry and 3-D printing at home: engineers and doctors use it to create things they really need. But for now, at least, the things you can print in plastic at home aren’t especially useful. 20 Plastics 1 Answer the questions. 1 What plastic objects do you have with you, or can you see around you, right now? 2 Could any of those objects possibly be made of a different material? What material would work? 3 Have you heard anything about 3-D printers? If so, what do you know about them? If not, can you guess what a 3-D printer might do? 2 Read the text.

Reading bank 26 © Oxford University Press This North Atlantic island is giving up fossil fuels El Hierro, an island about 1,400 kilometres off the coast of Africa, is home to 11,000 people. Until recently, their energy supply relied on oil that arrived by ship from the mainland. However, as energy prices increased, it became harder and harder for them to pay for the delivery of fossil fuels. Lucky, then, that the island has over 3,000 hoursper year when the wind blows hard enough to turn large wind turbines. The island’s wind turbines produce about 11 megawatts of power. But the wind doesn’t always blow on El Hierro, and when the wind stops blowing, the electricity stops flowing. The power grid doesn’t store electricity – it needs to be constantly generated, which is one of the big challenges of wind energy. The solution? El Hierro has created a 500,000m3 reservoir at an altitude of 700 metres, inside the dormant volcano at the island’s centre. That means that when the wind is slow, water can be allowed to flow downhill through hydroelectric turbines that generate the electricity the island needs. The water ends up in a smaller reservoir near sea level, where it is purified for drinking. You might imagine that the reservoir would soon drain all of its water downhill. But you’d be wrong. When the wind is blowing and there’s plenty of electricity available, pumps push desalinated seawater back up to the top of the hill, ready for the next drop in wind speed. The winds tend to blow the hardest at night, when people are asleep and energy demand is low, so this is the perfect time to refill the upper reservoir. The system generates enough electricity for two wind-free days. If the wind stops for three days, they’ll have a problem. But so far, that hasn’t happened. The project can generate enough energy to save the 40,000 barrels of oil they were importing each year, at a cost of €2 million at current oil prices. The system also provides drinking water and water for agriculture. 21 alternative energy 1 Imagine you are planning to start a community of about 10,000 people on an island in the middle of the ocean.

Hydrogen fuel cells produce electricity by combining oxygen and hydrogen. A series of fuel cells can provide enough power to drive an electric motor. The only waste product is water. So why aren’t we using it? 22 Mass transportation 1 Answer the questions. 1 What types of transport do you use regularly? 2 If you use mass transportation, what do you like about it?

Underline the correct answer. 1 The exhaust from a hydrogen fuel cell is water / CO2. 2 Hydrogen fuel cell technology has been perfected / is being developed and tested. 3 Hydrogen must be manufactured / is easily collected from the air. 4 The process of obtaining hydrogen produces water / CO2. 5 Hydrogen may be a practical / an impractical fuel source for trains. 6 Hydrogen-powered buses haven’t / have been tested on actual city streets. 7 The challenge of powering a car with a hydrogen fuel cell is the car’s small size / expensive price. 8 Hydrogen fuel cells will probably be useful for powering all / some vehicles in the next ten years or so. 3 Do you think hydrogen fuel cells for cars would be useful technology, or is researching them a waste of time? In fact, we are using it. Wheelchairs, trains, buses, bikes, golf carts, motorcycles, and a few other vehicles can already run on some form of hydrogen power. However, all of these are experimental vehicles. Challenges Hydrogen doesn’t occur naturally on Earth – it must be produced. At the moment, hydrogen is mostly produced by using methane (a powerful greenhouse gas) or other fossil fuels, which produce CO2. Also, the equipment required to produce and safely store hydrogen is large and complex – too big to fit on most vehicles. Researchers working on hydrogen power are trying to develop technology that will make hydrogen power more mobile for use in vehicles. They’re also trying to find practical ways to produce it without fossil fuels. Hydrogen trains Researchers in several countries have independently announced the development of hydrogen-powered trains. Trains are ideal for hydrogen fuel cells because they have a lot of storage space on board, and they also stop routinely at stations. Station stops for hydrogen trains would allow frequent refuelling. This would mean that the large and complex hydrogen-production equipment could remain in fixed locations. The Fuel Cell Bus Club This organization is running a trial using three Mercedes-Benz hydrogen fuel cell buses in eleven cities around the world. Each bus can carry about 70 passengers for a range of 300 kilometres – and costs $1.2 million. The aim of the project is to demonstrate that clean, urban public transport is possible. Fuel cell cars Most of the major automotive manufacturers are carrying out research into how to power cars with fuel cells in order to fight global warming. However, critics say that even twenty years in the future, a fuel cell car may not be possible, and also that fuel cells simply aren’t practical for smaller vehicles. Many believe that fighting global warming with fuel cell car research is a waste of time and money. The road ahead Hydrogen fuel cells have been proven to be effective ways of powering larger vehicles. However, there’s still the serious challenge of creating hydrogen in an environmentally friendly way. Experts are working on using wind, solar and nuclear energy for hydrogen production. H H H H Reading bank 28 © Oxford University Press Shale gas Energy solution or environmental nightmare? ‘Fracking’ could solve a lot of energy problems, but many people say it isn’t safe In April 2011, a small earthquake shook the English seaside resort of Blackpool. The following month, there was another. The earthquakes didn’t do a lot of damage, but they worried people. Geologists said there was a direct connection between the earthquakes and nearby gas exploration. The exploration work was stopped for a year, but has since been allowed to continue. What is shale gas? Natural gas usually comes out of the ground under pressure – it rises to the surface when a well is drilled. However, shale gas is different. It’s trapped inside a type of rock known as shale, and it doesn’t come out, even when a well is drilled directly into the shale. A technique called ‘fracking’ is used to extract shale gas. What is ‘fracking’? Fracking is short for ‘hydraulic fracturing’. Water under pressure is used to create cracks in shale – the rock that contains the gas. The water, containing sand and a mixture of chemicals, is forced into steel pipes that have been placed into the ground. Why do we need shale gas? Because there’s a lot of it. Experts believe that most countries that currently produce natural gas have huge reserves of shale gas. If they can use that shale gas, many of the world’s energy problems would be temporarily solved. What’s the problem with fracking? There are three main worries. First, fracking sometimes causesearthquakes, and earthquakes can hurt or even kill people, as well as damage buildings and other property. Second, the water used in fracking contains chemicals, and they can leak into drinking water under the ground. There are hundreds of chemicals used in gas drilling, and many of them can cause serious health problems for people and animals. Finally, fracking uses a lot of water. In some cases, fracking has used so much water that is has affected local water supplies and taken water that was needed for drinking and farming. Despite the potential problems, fracking continues today all over the world, and shale gas may soon be an important part of the world’s energy supply. 23 Petroleum engineering 1 Answer the questions. 1 The world is facing an energy crisis.

The Earth’s atmosphere – the layer of air around the planet – helps control the Earth’s temperature. CO2 in the atmosphere can cause problems because it allows sunlight to come through, but it tends to trap heat. Since the 1800s, people have added a lot of CO2 to the atmosphere, mostly through industrial activities. This is causing our planet to become warmer. Most experts agree that we should reduce the amount of CO2 in the air to reduce global warming. But some scientists think we may need to do more. Researchers in Britain would like to find a way to cut down the sunlight that passes through the atmosphere. They believe that if we could achieve this, we could stop global warming. They are trying to find a chemical that would reduce the amount of sunlight coming through the atmosphere if sprayed into the air. Researchers have known for years that large volcanic eruptions can cool the planet. The smoke from volcanoes contains sulphur dioxide. Chemical reactions in the atmosphere change the sulphur dioxide into tiny particles of sulphuric acid. The acid particles reflect the Sun’s radiation. This cools the planet. Scientists are not suggesting that we should spray sulphuric acid into the atmosphere – it’s a strong chemical that can damage people, plants, animals, and property. However, they do want to find a chemical that behaves in the same way. Not everyone thinks this is a good solution. If something unexpected happened, placing large amounts of chemicals into the atmosphere could cause serious changes in the weather or create other problems. Even the scientists who are working on the project agree that it might be too dangerous to try. But if global warming becomes a lot worse, we may have to consider it. 24 environmental engineering 1 Answer the questions. 1 What causes global warming? 2 What are people (including companies and governments) doing to address the problem of global warming? 3 Do you think we will be able to save the planet before we have very serious problems? 2 Compare your answers with the information given in the text. 3 Now read the text again.

The robot contains fuel cells that work like a cow’s stomach. The cells contain bacteria that consume the ‘food’. The resulting chemical reaction creates energy that powers the robot. Of course, everything that eats also produces waste – in the case of the Ecobot III, this is CO2. However, scientists point out that this isn’t the same as releasing CO2 by burning fossil fuels. The CO2 produced by the Ecobot III would have been produced by the food biodegrading anyway. In experiments, the Ecobot III has managed to ‘stay alive’ and feed itself for up to seven days. It moves around slowly on small wheels. The robot that runs The cheetah is the fastest land animal in the world. That’s why scientists at robotics firm Boston Dynamics chose it as the model for their four-legged, running robot. By looking closely at how a cheetah’s running body functions, they were able to create a robot that can run. The secret is in the flexibility of the robot’s back. The back bends so that the robot’s back feet can move as far forward as its chin as it sprints. This allows its feet to stay on the ground longer, making it fast – like a real cheetah. Currently, the cheetah robot can move at 45 kilometres per hour. That’s impressive, but at the moment, it can run only on a treadmill in the laboratory, with support. It also requires a power cable to an outside battery. Scientists are working hard to improve the robot’s balance and develop an onboard power source. The robot that looks like a person Earlier robots like ASIMO had a human shape but moved in a mechanical way. The Eccerobot has a body that uses systems and structures that are similar to the human body: artificial bones, muscles, and tendons. Where traditional robots have rigid joints and very mechanical movements, the Eccerobot’s movements are strangely human. Why? The robot’s ‘bones’ are connected by rubber bands and pieces of soft rubber tissue. When the robot moves, motors pull on the rubber bands, which in turn move the bones. The movement of the bones causes other parts to move slightly, rather than creating an isolated, mechanical motion. The robot’s ‘brain’ is, of course, a computer. At the moment, the main function of the computer is to receive information input from the robot’s body and react appropriately. For example, if you hand the robot a ball, it can gently take it from you. At the moment, the Eccerobot only has an upper body – it has no legs, and it can’t move itself. But as scientists perfect the robot’s movement and ‘thinking’ ability, it will be able to perform more and more activities. 25 Robotics 1 Answer the questions. 1 Think of some examples of robots in science fiction books or films (for example, Star Wars).

Why would you like to make it invisible? Invisible clothes Who wouldn’t want an invisibility suit? This isn’t yet possible, but researchers have discovered that they can create a type of ‘optical camouflage’. Here’s how: the person who wants to disappear wears clothing in a solid, light colour. Cameras film the area behind the person, and this background image is projected onto the front of the person. When you look at the person from the front, you can see the background projected on the person, and they becme difficult to see. Hidden submarines Sea creatures such as the octopus and cuttlefish can change the colour of their skin to blend in with the background. Their skin contains chemicals that make this possible. Marine biologists are now working with the military to understand exactly how some fish can change colour in an attempt to figure out how navy submarines could be made to do the same thing. This research is still in the very early stages. Disappearing buildings Architects and town planners often talk about the visual impact of a structure – will a new building make the city more beautiful, or will people complain because it’s ugly? Optical science researchers have discovered that some tiny crystals can bend and reflect light. In theory, if you covered an entire building in these crystals, they could reflect the light in such a way that the building would be very difficult to see. That’s probably not practical for city- centre buildings, but the military is definitely interested. Transparent people Brain scientists have created a chemical that makes brain tissue transparent. Researchers have made small pieces of mouse brain tissue completely see-through, which aids their research. Would it be possible to turn an entire living creature transparent? At the moment, we’re not even close. The chemical used on mouse brains is toxic, and not used on living creatures. However, scientists have already discovered a milder chemical that may have the same effect. Good old-fashioned camouflage Technology can do a lot to help the military hide people and things, but most soldiers still use grease paint on their faces, camouflage clothing, and some leaves when they need to hide. Soldiers are trained to use plants and other natural materials to hide or disguise military equipment, or to create decoys – things used to attract an enemy’s attention away from certain objects.

Rice production Fig. 2 There was a in solar energy production. dramatic rise The graph in Fig. 4 shows how much energy from different sources was used between 1950 and 2005. We can see that over this period the amount of energy used increased sharply, and the largest amount of energy came from petroleum. In 1950, just over 13,000 million billion Joules were used, but this figure rose sharply to reach a peak of roughly 40,000 million billion Joules in 1978. There was a dramatic fall to just over 30,000 million billion in the following five years, before rising rapidly to reach 42,000 million billion Joules by 2005. The second and third largest sources of energy were natural gas and coal, which each accounted for about 25,000 million billion Joules in 2005. The graph shows that insignificant amounts of energy came from renewable sources during this time, but there was a growth in the amount of nuclear electric power after 1970, reaching approximately 8,000 million billion Joules in 2005. The fall in energy consumption in the years around 1980 was probably due to the world oil crisis.

It can be seen that more than half of all passengers choose to travel by road, accounting for 58%, while just under half of all cargo is carried by road. About a third of all passengers use rail transport but only 11% of Croatia’s cargo goes by rail. Croatia has a long coastline, and just under a third of Croatia’s cargo is transported by sea. However, only 9% of passengers use this form of transport. This is probably because sea transport is cheaper for cargo but too slow for passengers. Pipeline and inland water transportation account for 8% and 1% of cargo transportation, respectively.

A B This report compares fourteen different practical measures that can be taken in order to find the most effective way to reduce the costs of heating an average home in Britain and reduce carbon emissions. To achieve this, the research compares the cost of installation, the number of years required to pay back the investment cost, and the amount of carbon saved each year. The study shows that the cost of insulating loft and walls is recovered within three years but saves only a small amount of carbon. Although it takes approximately thirteen years to pay back the cost of installing a ground source heat pump, it saves the maximum amount of carbon and is, therefore, the best long-term solution. Based on the research, we recommend that, where possible, new homes are fitted with ground source heat pumps.
