Superconductivity
According to the prominent scientist in this country V.L. Ginz-burg the latest world achievements in the field of superconductivity mean a revolution in technology and industry. Recent spectacular breakthroughs1 in superconductors may be compared with the physics discoveries that led to electronics and nuclear power. They
are likely to bring the mankind to the threshold of a new technological age. Prestige, economic and military benefits could well come to the nation that first will master this new field of physics. Superconductors were once thought to be physically impossible. But in 1911 superconductivity was discovered by a Dutch physicist K. Onnes, who was awarded the Nobel Prize in 1913 for his low-temperature research. He found the electrical resistivity of a mercury wire to disappear suddenly when cooled below a temperature of 4 Kelvin (-269 °C). Absolute zero is known to be 0 K. This discovery was a completely unexpected phenomenon. He also discovered that a superconducting material can be returned to the normal state either by passing a sufficiently large current through it or by applying a sufficiently strong magnetic field to it. But at that time there was no theory to explain this.
For almost 50 years after K. Onnes' discovery theorists were unable to develop a fundamental theory of superconductivity. In 1950 physicists Landau and Ginzburg made a great contribution to the development of superconductivity theory. They introduced a model which proved to be useful in understanding electromagnetic properties of superconductors. Finally, in 1957 a satisfactory theory was presented by American physicists, which won for them in 1972 the Nobel Prize in physics. Research in superconductors became especially active since a discovery made in 1986 by IBM2 scientists in Zurich. They found a metallic ceramic compound to become a superconductor at a temperature well above3 the previously achieved record of 23 K.
It was difficult to believe it. However, in 1987 American physicist Paul Chu informed about a much more sensational discovery: he and his colleagues produced superconductivity at an unbelievable before temperature 98 К in a special ceramic material. At once in all leading laboratories throughout the world superconductors of critical temperature 100 К and higher (that is, above the boiling temperature of liquid nitrogen) were obtained. Thus, potential technical uses of high temperature superconductivity seemed to be possible and practical. Scientists have found a ceramic material that works at room temperature. But getting superconductors from the laboratory into production will be no easy task. While the new superconductors are easily made, their quality is often uneven. Some tend to break when produced, others lose their superconductivity within minutes or hours. All are extremely difficult to fabricate into wires. Moreover, scientists lack a full understanding of how ceramics become superconductors. This fact makes develop-
ing new substances largely a random process. This is likely to continue until theorists give a fuller explanation of how superconductivity is produced in new materials.

How Did It All Begin?
Do you ever wonder why people do or wear, or say certain things? Why do they shake hands when they meet? Many things you say and do could have reasons that date back thousands of years.
For example, it is very strange to think that shaking hands — a friendly custom (обычай) today — was originally a means of keeping a stranger's (незнакомец) weapon hand where it could do no harm.
In primitive times, man never went about without some weapon of defence — usually a club (дубинка). Upon meeting a stranger a man could either stand and fight or turn away before discovering if the stranger was a friend or an enemy, or greet the stranger and possibly become friends.
But how could he be sure the stranger would be friendly and how could the stranger trust in return? There was only one way to show friendly intentions and that was for both men to lay down their weapons and hold out empty hands. For added insurance, each would reach for the other's right hand. As long as both men's hands were safely clasped, neither could harm the other. Therefore, a handshake originally was a means of self-defence.

The ancient Greeks are known to have been great watchers of the sky and also great thinkers. As they watched the sky night after night, it was natural for them to think that the Earth stood and the stars, planets, sun and moon were moving round the earth in space. They thought the sun to be between Venus and Mars. To explain the movement of the planets, however, was very difficult. Then one day a young scientist named Copernicus at Krakow University in Poland supposed that the sun and not the Earth should be the centre of everything. He was the first to explain properly our solar system. The ancient Greeks had made the mistake of thinking that because the stars and planets seemed to move as they looked at the sky, the Earth must stand. If you sat in a train and looked out at the trees, it would be easy to understand their mistake. The trees seem to be moving backwards, but really it is the train that is moving forwards.

Professor Brown: Hello, glad to meet you, prof. Smith, haven't seen
you for ages, since I left the University.
Prof. Smith: How do you do, prof. Brown, I haven't expected to
see you here. Are you interested in superconductivity problems? By the way, how are you making your living? I haven't heard anything about your work lately. I spent the last two years in Geneva as a member of a special UN committee.
Pr. В.: I am with Bell Telephone company. It is a global
leader in electrical engineering. And I deal with new technologies.
Рг. S.: Oh, your work is so important nowadays. Mankind needs energy for producing light, heat and transportation. This is the basis of our civilization.
Рг. В.: Sure, that's so. And as the population grows, so does the demand for better quality of life. Energy consumption increases daily.
Pr. S.: But with it the threat to clean air, pure water and soil increases too. These natural resources are not inexhaustible.
Pr. В.: Of course. We are developing new industrial systems to improve productivity, reducing the amount of raw materials and energy required. Our new advanced systems help to conserve energy too.
Pr. S.: In Geneva one of the problems I studied was the problem to generate, transmit and distribute energy with great efficiency. I think Doctor Carter's work in this field is the most promising. From the Agenda (повестка дня) we have all just received you can see that Dr.Carter will speak on his work tomorrow.
Pr.B.: I have already seen this paper on the program. I won't miss (пропустить) it. Have you attended the morning session?
Pr. S.: The most interesting was the discussion on the problems of the balance between the needs of mankind and the conservation of the natural resources.
Pr. В.: Have you taken part in it?
Pr. S.: Certainly. I've spoken about clean and efficient technology in the field of electrical engineering.
Exercise 4. Comment on the following statement.
The teaching routine procedures (заведенный порядок, общеизвестная и установившаяся практика) ought to be the main aim of education.
One point of view: Routine makes life and experiments easier, it saves energy; experience of past generations takes on the form of routine; routine helps us to avoid risks; thanks to routine we don't have to rediscover things; routine ensures efficiency while experimenting, it enables us to achieve a high level of predictability.
A contrary point of view: Routine kills invention and discovery, it is opposite to creativity; it is necessary to avoid routine so that the world can be changed for the better; young people ought to develop their imagination, but not learn routine; routine is the exact opposite of youthfulness; routine is boring; the best idea would be to combine routine with improvisation.
Exercise 5. Conduct a round-table discussion on «Superconductivity Research».
Use texts 11 А, В, С as a basis for the preparation of oral talks and discussion. Useful words and phrases of scientific communication are given in exercise 5 (see Lesson 10 «Conversation»).

For a long time Edison's visitors wondered (удивлялись) why the gate (калитка) to his garden was so difficult to open.
Once his friend said: «The gate to your garden is so heavy. I have to use all my strength to open it. I cannot understand this. You are such a brilliant man. You can invent something better». «The gate seems to be all right», Edison answered with a smile. «The fact is that it is a brilliant invention.» «You are laughing at me, sir!» «No, I am not. The gate is connected to a pump. Everybody who comes in pumps twenty litres of water out of the well (колодец).»
An absent-minded (рассеянный) professor was once travelling by electric train, and when the conductor came the professor couldn't find his ticket.
«It's all right, sir», said the conductor who knew the professor very well, «I'll come at the next station».
But at the next station there was the same difficulty, the professor couldn't find his ticket anywhere.
«It's all right, sir, it doesn't matter (не имеет значения)», said the conductor. «No, no I must find the ticket, I must know where I'm going to!»
Text 11B Прочитайте текст и озаглавьте его.
Superconductivity is a state of matter that chemical elements, compounds and alloys assume on being cooled to temperatures near to absolute zero. Hence, a superconductor is a solid material that abruptly loses all resistance to the flow of electric current when cooled below a characteristic temperature. This temperature differs for different materials but generally is within the absolute zero (-273 °C). Superconductors have thermal, electric and magnetic properties that differ from their properties at higher temperatures and from properties of nonsuperconductive materials.
Now hundreds of materials are known to become superconductors at low temperature. Approximately 26 of the chemical elements are superconductors. Among these are commonly known metals such as aluminium, tin, lead and mercury and several less common ones.
Most of the known superconductors are alloys or compounds. It is possible for a compound to be superconducting even if the chemical elements constituting it are not.

New Hope for Energy
Recently some ceramic materials have been found to be superconductors. Superconducting ceramics are substances which can transmit electric currents with no loss of energy at temperatures much higher than conventional superconductors (that is, at the temperature of liquid nitrogen).
One use for the new superconductors would be to replace those that need the extreme cold of liquid helium — huge superconducting electromagnets used in nuclear magnetic resonance research, atomic particle acceleration and research reactors.
Other types of electromagnets made with superconductors could be used to lower the cost of electric generation and storage. Such uses may take 10 years of research, a quicker use will probably be in electronics.
Researchers now estimate that tiny but immensely powerful highspeed computers using superconductors may be three to five years away. Further off are 300 m.p.h. trains that float on magnetic cushions which now exist as prototypes but may take at least a decade to perfect. Power lines that can meet a city's electric needs with superconductor cables may be even further in the future.
Meanwhile, scientists around the world are trying to turn the new materials into useful products. Among the most notable is a micron-thin film to transmit useful amounts of electric current without losing superconductivity. The film could be used in the microscopic circuitry of advanced computers as high-speed pathway (маршрут, соединение) between computer chips.
Several nations are known to be very active in superconductor research. For example, the United States is spending millions of
dollars on such research, much of it for military uses: projectile accelerators, lasers, ship and submarine propulsion.

Прочитайте текст и расскажите по-английски о Массачусетском Технологическом Институте.
Massachusetts Institute of Technology
MIT is an independent university located in Boston area. It was founded in 1861 by William Barton Rogers, a distinguished natural scientist, who believed professional competence to be best fostered (воспитывать) by the combining of teaching, research, and the application of knowledge to real-world problems. MIT held its first classes in 1865 after having delayed opening because of the Civil War. There were approximately 15 students enroled at that time.
Today MIT has about 9,700 students, a faculty (профессорско-преподавательский состав) of approximately 1,000 and several thousand research staff. The total teaching staff numbers more that 1,800. The institute is broadly organized into five academic Schools — Architecture and Planning, Engineering, Humanities and Social Science, Management and Science — and a large number of interdisciplinary programs, laboratories, and centers, including the Whitaker College of Health Science, Technology and Management. A unique feature of MIT is that undergraduates join with graduate students, faculty, and staff to work on research projects throughout the institute.
Most academic activities take place in a group of interconnected buildings designed to permit easy communication among the Schools and their 22 departments. Across the street from this set of buildings there are athletic fields, the student center, and many of the dormitories.
The main purpose of the academic program at MIT is to give students a sound command (прочное усвоение) of basic principles, the habit of continued learning and the confidence that comes from a thorough and systematic approach to learning. This results in continued professional and personal growth, especially in today's rapidly changing world.
The two essential parts of all MIT educational programs are teaching and research. Both of these activities carried on together have greater potential than either performed alone. They provide experience in theory and experiment for both students and teaching staff.
Each student pursues a degree (стремиться получить степень) in one of the departments.. Undergraduate courses at MIT lead to the degree of Bachelor of Science (S.B.). The academic programs require four years of full-time study for the Bachelor of Science. Degrees are awarded on the basis of satisfactory completion of general institute and departmental requirements (общеинститутские и кафедральные требования) in each program.
There is enough flexibility (гибкость), however, to allow each student, in collaboration with the adviser, to develop an individual program in accordance with his or her own interests and preparation.

The practical applications of superconductivity are limited because of the very low temperatures required. Some materials, for example lead, become almost perfect conductors at very low temperatures at the absolute zero (-273 °C). However, a number of uses have been proposed.
If a current is induced by a magnetic field in a ring of superconducting material, it will continue to circulate when the magnetic field is removed. In theory this could be made use of in the memory cells of computers. Memory cells made of superconducting material could store information indefinitely. Because of the zero resistivity of the cells, the information could be retrieved quickly, as fast as 10~8 seconds.
90 per cent of the total losses in modern transformers is due to the resistance of the windings. Transformers could be made with windings cooled to the low temperature at which superconductivity occurs. The resistance would be zero and the transformer would be almost ideal. Similarly, a 100 % efficient electric motor has been proposed using the magnetic field of superconducting coils.

The International Space Station
The International Space Station (ISS), the most complex and expensive structure that has ever been launched and built in space, is expected to be a permanent off-planet extension1 of human civilization. When completed, it will be a multi-room hotel and research facility orbiting the Earth every 90 minutes. By that time, resupply and assembly flight by shuttles or rockets will have become routine.
The Russians and Americans are partners in this international enterprise. The three-person multi-national crews will be alternately composed of two Americans and one Russian followed by a Russian majority. Later a six or seven-person crew will occupy the station. Some astronauts may stay on the ISS up to 187 days, but there are no plans yet for longer missions. The official life expectancy of the station itself is 10 years, but it should last much longer.
Five times the size of the Russian space station Mir, the ISS will be one of the biggest objects in the night sky, looking like a supersize Lego set2, almost as long as a football field. Only the Moon and Venus will be bigger and more visible.
The fifth-generation station's complexity is as awesome3 as its size. Built by a partnership of 16 nations, the ISS will consist of 36 modules and hundreds of individual elements that come from all over the world. The station involves the most technologically advanced nations — Russia, the United States, Canada, Japan, Brazil, and 11 European nations. There will be many interconnected parts from so many countries that it would be impossible to predict how they would interact.
Hence, it is very important that all of these elements made by different suppliers should fit together properly and work exactly as planned. But even if all the parts fitted perfectly, the assembly process itself in orbit would be risky. The space station is flown while it is being constructed and each new building block added might change the way the station behaves in flight, which could result in serious trouble.
The ISS may be the world's most ambitious engineering project in history, but it could not have been realized without previous extensive experience in operating the Russian Mir space station. Mir
was a great achievement. Russia learned how to build and maintain complex structures in space. Mir also gave citizens of more than a dozen countries their first opportunity to explore space. It should be noted that Mir has proved to be the perfect training ground for the ISS. For more than a decade, at least two humans were always in low Earth orbit. That is why it was planned that Russia would supply and deliver 12 modules for the future station, each being a key module among its 36 ones. They are: the basic power module, the control, the life support, the service modules and others.
What is the purpose of the ISS? It is a political program as well as a science program. This program is no longer only about conducting scientific investigations in the absence of gravity, or about learning how to build a massive project weighing 400 tons in orbit, or about establishing the base for a future trip to Mars. The ISS is more than merely the next great adventure of the space age. It is also about promoting international cooperation and creating thousands of peacetime jobs for highly skilled workers and engineers.
The implementation of the broad international program would require more than $40 billion. Some space experts would like to attract commercial users such as, e.g., biotechnology companies in order that the cost of the station should be lowered. And some specialists have even suggested that the station be used for advertising and Hollywood filmmaking.

Dolly Madison was born in South Carolina while her parents were visiting there. She was soon taken to Virginia where she was educated. She was taught by her Quaker parents to say «thee» and «thou» for «you». Dolly was married to John Payne who died a short time afterwards from yellow fever. Several years later she was married to James Madison, a brilliant lawyer. When Thomas Jefferson was elected President of the US, James Madison became Secretary of State. Mr. Jefferson was a widower, so Dolly was often invited to preside at the White House. When James Madison was elected president, Mrs. Madison was the hostess of the White House on all occasions. People from everywhere were impressed with her sincerity and her love for humanity.

Exploration experts suggest that the tiny moon Phobos should be used as a perfect place for gas refilling station. Some scientists think Phobos rocks to contain crystalline ice. If one heats them, it will be possible to produce water. The latter could be divided into hydrogen and oxygen which are necessary components for rocket propulsion. Such a fuel supply would greatly reduce the amount of weight that must be delivered from the Earth for manned missions to Mars. Thus, it might be possible for spacecrafts to leave the Earth for Mars carrying no return fuel. To get home, they should simply fill up at Phobos.

Satellites
Peter: Ann.:

P.
A.
Hello, Ann. How did you happen to come to California?
Hello, Peter. How are you? My father got a job here. It is so exciting to meet you here. I've not seen you since you graduated from the University.
I'm working on a newspaper. I cover the space research problems. Now I study the application of space satellites for scientific purposes.
I think that the best application of satellites is for military purposes.
You are absolutely wrong. The most promising field of application of satellites is the scientific one.
Oh, Yes, I know satellites look down on everything: the clouds, forests and oceans, the winds, ice on the sea. But don't forget spy (шпион) satellites.
P.: Spy and weather satellites gather data for forecasting. The Japanese have a satellite studying the ocean; European and Russian satellites produce radar images of the ground; an American satellite is studying the upper atmosphere.
A.: It seems to me that the era of satellites has passed. You see, the Japanese have already delayed the launch of their earth observing mission.
P.: Yes, they did, because of cost. The most effective way to
gather data is not always with a big satellite. A.: Have you met my elder brother Mike? P.: Of course, I have. We played in the same football team at the
college, though he is about three years older than me. A.: He is five years older than you. He takes part in the research
programme at the Goddard Institute for Space Studies. They
are developing now a small cheap satellite. It would carry
three simple instruments to measure clouds, water vapour and
surface temperature. P.: Oh, really. I think, that such researches make sense, and help
develop a single Global Climate Observing System.
A.: Such a system could change the world or at least see the world changing.
Exercise 4. Comment on the following statement.
Space exploration ought to be abandoned (откладываться) until more important problems of mankind have been solved.
One point of view: Space exploration is very expensive; food production is far more important than Mars studies or Moon walks; it is immoral to spend huge sums of money on space exploration while millions of people suffer hunger (голод); space exploration is useless anyway because we can't colonize other planets; it would be much better to colonize, for example, the Sahara before trying to colonize the Moon or Mars; mankind must not waste its resources.
Л contrary point of view: Space exploration is of great significance for scientific and technological development; space exploration gives man new knowledge that he can use for other purposes; we may find 10,000 things to do on the ISS that nobody has thought of or even imagined.
Exercise 5. Conduct a scientific conference on: «The potential of space exploration for peaceful purposes».
Use texts 12 A, B, C, exercise 3 (Satellites) as a basis for the preparation of oral talks and discussion. Useful words and phrases of scientific communication are given in exercise 5 (see Lesson 10 «Conversation»).
