Упражнение 31.Прочитайте ипереведите без словаря:

Let's look at the progress the computers have made in their development. Besides the great changes in size and speed, we now have machines which change numbers into pictures, words and sounds. The next big change will be when we get computers that will understand human language. But now if you want to programme your own computer, you must learn it's language. It does not understand yours. For example you talk with an Englishman. You make one small grammar mistake „have“ instead of „has“. The man understands what you mean and the talk goes on. But if you make even a smallest mistake in computer language the talk breaks down and you must go back to the beginning.

Andrew Jackson's Poor Health

After his wife died Andrew Jackson, former President of the United States, became increasingly irritable (раздражительный). Не also worried (.беспокоиться) more and more about his health. Several members of his family had died after a paralytic stroke (паралич) and Jackson was sure he was going to die in the same way. He therefore lived in daily fear (страх) of getting such a stroke. One day, during a party at his home, he was playing chess with a young woman. Suddenly Jackson's hands dropped to his side, his face became white. Several friends run to him. «At last it has come», Jackson said weakly." I have had a stroke. My whole right side is completely paralyzed". «How do you know»? someone asked. «Because», Jackson said, «in the last few minutes I have pinched (ущипнуть) my leg several times and there is absolutely no sensation in it». «Oh, I beg your pardon, sir,» said the young woman he played with, «but it was my leg you were pinching.»

Computers Concern You

When Ch. Babbage, a professor of mathematics at Cambridge University, invented the first calculating machine in 1812 he could hardly have imagined the situations we find ourselves in today. Almost everything in modern world is done with the help of computers — the complicated descendants (потомки) of his simple machine. Computers are being used more and more extensively in the world today, for the simple reason that they are far more efficient than human beings. They have much better memories and can store (запоминать) great amount of information and they can do calculations in a fraction of the time required by a human

mathematician. No man alive can do 500,000 sums in one second, but a modern computer can.

In fact, computers can do many things we do, but faster and better. They can control machines at factories, work out tomorrow's weather and even play chess.write poetry or compose music. Let's look now at some of the ways in which computers concern people in their daily lives and work.

Many people associate computers with the world of science and mathematics, but they are also a great help to scholars in other subjects: in history, literature and so on. It is now possible for a scholar to find a book or an article he needs very quickly, which nowadays when a million or more new books are published each year is quite an advantage. You tell the computer which subject you are interested in and it produces any microfiche (микрофише, диамикрокарта) you need in seconds.

There are also systems which are being developed to translate articles from foreign magazines by computer and to make up many lists of information which are needed in a modern library. So, computer can help us to deal with the knowledge explosion in many ways. One can imagine a time when libraries will be run by computers, without human beings at all.

Or, let's take another example. When a man drives a car for long distances he has two problems: to keep the carat a constant speed and watch that he does not run into the car in front of him. Engineers are now experimenting with a system which has a computer control of these two problems. The car's computer keeps the speed constant. At the same time the distance between the car and any other car in front of it is measured by a beam of light transmitted forwards. The beam meets the rear reflectors of the car in front and it is reflected back, which enables to measure the distance. This information is fed to the computer which adjusts (регули­ровать) its speed control accordingly.


Прочитайте текст и озаглавьте его. Кратко изложите основное содержание текста по-английски:

Sir Isaac Newton was a supergenius of science who among other things invented calculus (исчисление) stated the laws of gravity and optics. But it turned out (оказываться) Newton also made mistakes. The University of Chicago announced recently that R.Garusto, 23, a physicist, had discovered in one of Newton's calculations an error that had been undetected for three centuries.

The young scientist discovered it while he was studying Newton's masterpiece (шедевр) of physics «Principia» (1687). Newton had derived (выводить) a figure for the Earth's mass based on his new theory that a single force — gravity — governed (управлять) falling bodies on the Earth and the motion of planets around the Sun. The calculation depended on the angle (угол) between two lines from the Earth to the Sun, but because that angle was not exactly known at the time, Newton used slightly different


figures in «Principia». It was that mistake that the young scientist found, a discovery that was soon confirmed (подтвердить) by other physicists. The mistake has no influence on Newton's theory, but its discovery was enough to get him a prize from the University of Chicago.


Прочитайте текст и расскажите по-английски, из каких зданий состоит комплекс Библиотеки Конгресса и каким известным деятелям посвящено каждое из них. Найдите предложения со словами houses и numbers, переведите и запомните их значения.

The Library of Congress

The Library of Congress is the Nation's library in the USA. It serves not only to members and committees of the Congress, but to libraries throughout the USA and the world and to the scholars, researchers and scientists who use it.

Its foundation was laid in 1815 when President Thomas Gefferson offered his personal library accumulated for 50 years and considered one of the best in the United States at that time as the basis for a great national library.

Now the Library of Congress complex on Capital Hill includes three buildings. The Thomas Gefferson Building, which has been buill in Italian Renaissance style, is the oldest of them. It was the largest and costliest (роскошный) library building in the world when it was completed in 1897. It is decorated with splendid sculpture, murals (фрески) created by 50 American artists. Its Main Reading Room is 160 feet high.

The Room houses a collection of 45,000 reference books (справочни­ки), a part of the extensive main catalog of more than 23 million cards and desks for 212 readers. The Computer Catalog Center provides public access (доступ) to the Library's automated catalog.

The simply designed John Adams Building faced with white marble (мрамор), was opened in 1939. Sculptures on its large bronze doors repre­sent 12 famous writers.

The white marble James Madison Memorial Building opened in 1980 more than doubled the Library's available Capitol Hill space. The building which is the official memorial to the Nation's fourth President contains the James Madison Memorial Hall, exhibition areas, eight reading rooms, offices and storage areas for collections which number over 50 million items (предметов).

Made in Space

^ This label «Made in Space» for industrial materials will probably surprise no one in the not so distant future. They may include superconductors, new kinds of alloys, substances with peculiar magnetic properties,supertransparent laser glass, polymers, plastics, and so on. Numerous experiments carried out at the Russian orbital space stations have paved the way to the development of methods and means of industrial production of new materials of better quality on board3 a spacecraft. Experts estimate that within a few coming years industrial production of various materials will be started in space.

v Conditions on board a space vehicle orbiting the Earth greatly differ from those on its surface. However all of these conditions can be simulated on Earth, except for one — prolonged weightlessness. Weightlessness can be created on Earth, but only for a few seconds. A space flight is another matter: a satellite orbiting the Earth is in a dynamic zero-gravity stale, i.e., when gravity is cancelled out by inertia.

->>What can weightlessness be used for? Many well-known processes go on differently due to the absence of weight. The Archimedes principle is no longer valid and, consequently, stable-stale6 liquid mixtures can be obtained, the components of which would immediately separate on Earth because of different density. In case of melts7 of metals, glasses or semiconductors, they can be cooled down to the solidification point even in space and then brought back to Earth. Such materials will possess quite unusual qualities.

tlIn space there is no gravitational convection, i.e., movements of gases or liquids caused by difference of temperatures. It is well-known that various defects in semiconductors occur because of convection. Biochemists also have to deal with the worst aspects of convection, for example, in the production of superpure biologically active substances. Convection makes it very difficult on Earth.

'i Following the launch of the first orbital stations the specialists started experiments aimed at proving the advantages of the zero-gravity state for the production of certain materials. In this country all orbital stations from Salyut 5 onwards were used for that purpose, as well as rockets. Since 1976 over 600 technological experiments have been carried out on board manned and unmanned space vehicles.

<* The experiments proved that many of the properties of the materials obtained under the zero-gravity condition were much better than those produced on Earth. Besides, it has been established that it is necessary to develop a new science — physics of the weightless state — which forms the theoretical basis for space industry and space materials study. This science has basically been developed.The methods of mathematical modelling of the hydromechanical process under the zero-gravity condition have been created with the help of computers.

\ Special space vehicles will also be needed for industrial production of new-generation materials. Research has shown that the acceleration rate on board these vehicles must be reduced to the minimum. It was found that space platforms in independent flight carrying the equipment were most suitable for producing materials. These vehicles will have to use their own propulsion systems to approach their base orbital station after a certain period of time. The cosmonauts on board the station can replace the specimens. Many new and very interesting projects are planned for orbital stations. Here is one of them. Convection does not allow to grow large protein crystals on Earth. But it is possible to grow such crystals under the zero-gravity condition and to study their structure. The data obtained during the experiments can be useful for the work of laboratories on Earth in using the methods of gene engineering. Thus, it may be possible to make new materials in space and also to obtain valuable scientific data for new highly efficient technologies on Earth.

\ь Preparatory work for industrial production in space at a larger scale is being carried out in Russia, the USA, Western Europe and Japan. It should be said that according to the estimates of American experts production of materials in space is to bring 60-billion dollars by the year 2000.

The first step in any industrialization project, for example, on the Moon should be preparation for plant construction. It is economically desirable to use local materials for this. It is well-known that metals form the most important group of engineering materials. One must know that they possess necessary mechanical and physical properties. They can be easily fabricated into various forms by a variety of techniques. They are hard, tough (пластичный), strong and temperature- resistant, a combination of properties not available in any other materials. The properties of metals can be changed by heat treatment so that the fabrication is much easier since the work pieces can have properties quite different from those needed in the final product. -

A Trick on a President

W.H.Harrison was the ninth President of the United States. Like so many other early American presidents he was born in a small town. As a boy, he was extremely quiet. In fact, he was so quiet that he had the reputation of being very stupid (глупый). The town people therefore often used to play tricks (шутка) on him. For example, they would put a nickel and a dime (монеты в 5 и 10 центов) in front of him and tell him to take whichever one he wanted. He would always choose the nickel and they would laugh at him.

One day, a woman took pity (пожалеть) on him. She said: «William, why do you always choose the nickel instead (вместо) of a dime? Don't you know that a dime, though smaller in size than a nickel, is worth (стоить) much more than a nickel?» «Certainly I know it», William answered. «But if I chose the dime they wouldn't play the trick on me any more.»
