TEXT A.ALBERT EINSTEIN Albert Einstein, a well-known German physicist and mathematician, was born in Germany on March 14, 1879. His unusual ability to mathematics and physics began to show itself at a technical school in Zurich. At the age of 21, after four years of university study, Albert Einstein got a job as a clerk in an office. But already in 1905 he made revolutionary discoveries in science. He published three papers in the field of physics and mathematics.In the first he explained the photoelectric effect by means of Plancks quantum theory.

The second paper developed a mathematical theory of Brownian motion. He presented his third paper on Special Theory of Relativity to a physical journal. Einstein expressed his theory in the equation E mc2, roughly that energy equals mass times the square of the speed of light. All over the world scientists read the work with great surprise.Few physicists understood its importance at that time. Everybody wanted to know as much as possible about the author. In which institute did he teach In what laboratory did he do his research Einsteins fame among scientists grew slowly but surely.

For a few years he lived in Prague where he worked as a professor.When he came to Prague, he often told his students I shall always try to help you. If you have a problem, come to me with it, we shall solve it together. He liked questions and answered them at once, for there were no simple or foolish questions for him. He spoke much with his students about scientific problems and his new ideas.

His advice to students was, Dont take easy problems. In 1921 Einstein got the Nobel Prize in physics not for the theory of relativity but for a logical explanation of the photoelectric effect. After the Great October Socialist Revolution in Russia Einstein became a true friend of the young Socialist Republic. He established scientific contacts with his colleagues in Soviet Russia.In 1922 he became a foreign member of the Russian Academy of Sciences for his outstanding contributions to physics and mathematics.

On March 14, 1979 by UNESCO decision all people throughout the world celebrated the birth centenary of the great 20th century scientist.Текст 1. АЛЬБЕРТ ЭЙНШТЕЙН Альберт Эйнштейн, хорошо известный немецкий физик и математик, родился в Германии 14 марта 1879 года. Свои необыкновенные способности по математике и физике начинал показывать ещ с технической школы в Цюрихе.

В 21 год, после четырех лет обучения в университете, Альберт Эйнштейн получил работу клерком в офисе. Но уже в 1905 году он сделал революционное открытие в науке. Он опубликовал три доклада в области физики и математики. В первом он объяснял фотоэлектрический эффект посредством квантовой теории Планка. Второй доклад развивал математическую теорию броуновского движения. Он представил свой третий доклад Специальная теория Относительности в физическом журнале.Эйнштейн выразил свою теорию уравнением Е mс2, количество энергии приблизительно равняется массе умноженной на квадрат скорости света.

Во всем мире ученые читают работы с большим удивлением. Немногие физики понимали значение этого в то время. Каждый хочет знать столько об авторе В каком институте он преподавал В каких лабораториях проводил свои исследования. Известность Эйнштейна среди учных росла медленно, но верно. В течении нескольких лет он жил в Праге, где работал в качестве профессора.Когда он приезжал в Прагу, он часто говорил своим студентам Я всегда стараюсь помогать вам. Если у вас есть проблемы, обращайтесь ко мне, и мы будем решать их вместе.

Он любил вопросы и давал ответы на них сразу, даже если они непростые и глупые вопросы брался за них. Многие из таких студентов знают о проблемах науки и у них новые идеи. Совет студентов утверждает Нет легких проблем.В 1921 году Эйнштейн получил Нобелевскую Премию по физике не за теорию относительности, а за логическое объяснение фотоэлектрического эффекта.

После Великой Октябрьской Социалистической революции в России Эйнштейн становится верным другом молодой Социалистической Республики. Он установил научные контакты со своими коллегами в Советской России. В 1922 году он становится иностранным членом Российской Академии Наук и вносит выдающийся вклад по физике и математике. 14 марта 1979 года решением ЮНЕСКО люди всего мира праздновали столетие со дня рождения великого в 20 веке учного.TEXT B.INTENSIFIKATION-90 The exhibition Intensifikation-90 which is devoted to economic and social developments of Leningrad region was on in Leningrad.

Its exhibits show the Leningraders efforts to improve the quality and efficiency of the region production. A large section of the exhibition demonstrates electronics The most impressive of the exhibits are robots. They can cut metals, drill holes, compute and teach. All robots are very much things of the present.A multipurpose lathe-robot is specially interesting in that it can ask questions.

An engineer showed how it works. He pressed a key which has the mark Thread cutting. And Thread pitch immediately appeared on the video displey screen. The engineer pressed another key with the mark I. Another question came on Thread length. The robot has to get all the answers to all its questions before it goes to work. Another exhibit was a Sfera robot which was to operate some metallurgical processes.Before it starts working its operator must take him by hand and go through all the programme.

The robot memorizes the instructions and then is able to do everything by itself and without any mistakes. Its memory can hold as many as 70 programmes. Practically all the equipment on display serves to improve the equipment on display serves to improve the productivity.Intensifikation-90 progpamme provides for high increase in production of technologically perfect, top-quality and efficient types of machinery for Leningrad region.

TEXT A.MACHINE-TOOLS-A MEASURE OF MANS PROGRESS The variety and combinations of machine tools today are unlimited. Some of them are very small and can be mounted on a work bench but others are so large that we have to construct special buildings to house them. There are some basic operations at any workshop.They are turning, drilling, threading, etc. The main machine-tool a workshop is the multipurpose lathe. What is a lathe It is a power-driven machine with special tools which can cut or form metal parts.

The metal that cuts another metal must be very hard and so tools should be made of very hard steel alloys. The tool itself is very small in comparison with the mechanism that is to direct it. Technological progress improves accuracy of machine tools.Todays equipment can produce parts with very high accuracy. One can find a number of machine tools that can measure and inspect their production themselves machine tools that are to handle the parts mechanically and automatically.

Such machines can hold the parts which are to be measured and be able to indicate precise measurements themselves. A great many of such clever machines can be found today in our industry. Since machine tools become faster and more complex, automatic measurements and inspection ought to be of greater importance. Automation is one of the main factors of engineering progress.Flexible production lines form the basis for automated workshops.

The main principle of such a flexible line is the fact that it can be switched over from one product to another, which has a similar structure but a different outline, almost instantaneously. It is equally efficient in conditions of will serve to increase the productivity. The USSR and other highly industrialized countries begin making use of flexible modules and automated workshops on a broad basis.TEXT A.ASTRONOMICAL CAPITAL OF THE WORLD Two great observatories, Greenwich and Pulkovo, occupy a leading place among the observatories of the world.

Some scientists call Pulkovo the astronomical capital of the world. Pulkovo is situated in a hilly area some kilometers from Leningrad. You cant get to Pulkovo by train when the railway was being built the astronomers specially asked that it should be kept several kilometers away so that there should be no vibration to affect the sensitive instruments.The work started in 1839, when the observatory was opened, is being continued now. This is the eternal work of astronomers to define the precise co-ordinates of the stars, to find out the exact addresses of heavenly bodies.

But today the scientists also conduct a time service, they study activity of the Sun, follow the flights of the Earth sputniks and calculate their orbits. The scientists of the observatory have made a valuable contribution to the study of the cosmos by observing Soviet artificial Earth satellites, man-made moons.The study of their orbits is very important for the flights of manned spaceships.

The Pulkovo observatory has a radio-astronomy department equipped with modern apparatus. The big radio-telescope installed there is stronger than any other telescope in the world. With the help of this powerful devise the scientists of the Pulkovo observatory carry out a number of observations of Venus, Jupiter and other planets.It is necessary that before flying to other planets scientists should get the greatest possible information about the heavenly bodies.

The astronomers have obtained extremely surprising results due to radio- astronomical observation.By means of the radio-telescope some remarkable studies of the surface of the Sun and of solar activity have been made and a method of investigating the movement of planets has been worked out. Astronomical observation and cosmic experiments are spheres of scientific research in which broad co-operation of scientists of various countries would be most effective.

Soviet scientists, workers and technicians have produced and launched space rockets in the direction of the Moon, Venus and Mars and are fulfilling the noble dreams of mankind. May there be peaceful ships flying the space routes and may they serve the interests of all the people of the world TEXT A. TODAYS ASTONISNING COMPUTERS Not long ago computers were not very reliable and comparatively slow in operation.Since then, several generations of complex electronic computing equipment have been developed, each being significantly better than the one before it. Almost every day a new use is found for these astonishing devices to help man. We know a computer to be a complex electronic device that can store and process vast quantities of information.

Following instructions, computing equipment will perform calculations such as addition, subtraction, multiplication and division, and provide the answers to a large variety of problems in a tiny fraction of time. A computer is known to be the heart of an electronic data processing system, other parts of equipment being auxiliary.

There are two main types of computing equipment digital and analogue. They work differently and yield different results. The digital computer is performing a much broader range of functions than the analogue one. The analogue computer, as its name implies, produces analogues or parallels of the process to be described or the problem to be solved.Both the digital and analogue computers must be programmed.

This means they must be set up in such a way that they can produce a result from the information fed into them, and the information itself must be organized so it can be handled by the machines. These devices working by electronic impulses perform at fantastic speed and with great precision. Looking to the future, computer makers see no end to the things they would like to accomplish.The computer of the future seems to be developed by using bionics biological functions of plants and animals as a guide in designing electronic circuits.

Nowadays computer makers are working at the problem of introducing small computers into our everyday life making them personal. They are trying to develop a computer that will understand human language. Each new generation of computers opens up new possibilities for basic and applied research.
