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
Planck's 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?
Einstein's 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, 'Don't
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 ещё 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 учёных 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 учёного.
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.
'Интенсификация-90'
Выставка 'Интенсификация-90', которая посвящена для экономического и
социального развития Ленинградской области проходила в Ленинграде. Её
экспонаты, представленные усилиями ленинградцев предназначены для улучшения
качества и производительности областного производства. Большую часть
выставки занимал показ электроники.
Наиболее впечатляющий экспонат был робот. Он может резать металл,
сверлить отверстия, подсчитывать и обучать. Все присутствующие роботы очень
хорошие вещи в подарок. Многоцелевой токарно(станочный) робот особо
интересен тем, что может 'задать вопрос'. Инженер показывал, как он
работает. Он нажимал на кнопку, которая называлась 'Резьбу нарезать'. 'И'
Шаг резки резьбы?' после этого появляется на видео (показывающем) экране.
Инженер нажимает ещё одну кнопку промаркированной 'І'. Ещё один вопрос
появляется: 'Длина резьбы'. После того как робот получит все ответы на
вопросы, приступает к работе.
Ещё один экспонат 'Сфера' – робот, который выполняет операции
некоторых металлургических процессов. До начала работы механик-оператор
должен взять его 'в руки' и пройти через все программы. Робот вспоминает
инструкции и способен делать все что нужно и без всяких ошибок. Его память
может держать около 70 программ.
Практически всё оборудование, выставленное на показ, служит для
улучшения производительности. Программа 'Интенсификация-90' служит для
увеличения роста производства технологически совершенного,
высококачественного и продуктивного, типичного машинного оборудования для
Ленинградской области.
TEXT A.MACHINE-TOOLS-A MEASURE OF
MAN'S 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. Today's
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 can't 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. TODAY'S 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.
