Exercise IV. Read the text
Computers.
Many companies have now computerized their accounting procedures because computers can do the work more quickly and more accurately than people. The work the computer does is called data processing. The part of the computer the data are processed with is called CPU (central processing unit). This contains only electronic components, called microchips.
A computer can only do what it is instructed to do. The instructions the computer stores are called the computer program. The people who write these instructions and put them in the computer are called computer programmers The parts of the computer most people use are called terminals. The terminals are usually a keyboard which look like a typewriter, and a VDU (visual display unit) which looks like a television, or a printer. Information put into the computer on the keyboard is called input. When the computer shows the result of the data processing on the VDU, this is called output. When computers go wrong, it is usually because mere is something wrong with the input. In other words, it is a mistake made by a person, not by the computer.

Electric Current and its Uses.
Electric current serves us in a thousand ways. The electric current was born in the year 1800 when Volta constructed the first source of continuous current. Since then both Russian and foreign inventors contributed greatly to its practical application. Nowadays it would be impossible to imagine modern civilization without the electric current. If there were no electric current, there would be no vacuum cleaners, refrigerators, telephones and many other things. People are more familiar with the application of electric current in their everyday life than they are with its numerous industrial applications. However electricity finds its most important use in industry. Would a factory work if there were no electric motors transforming electric energy into mechanical energy? Of course, it wouldn't. Another example of an important industrial use of the electric current is the electrically heated furnace. Great masses of metal meet in such furnaces flow like water. Speaking of the melted metals, we might mention a device working on electricity. Its name is electric pyrometer with the help of which it is possible to measure the temperature of hot flowing metals. Of course it would be impossible to enumerate all the industrial applications of the electric current, but even those examples you have read about in the text can give you the idea of the electric current serving us in a thousand ways.

Exercise VIII. Read and translate text 2.
Scientifically speaking energy is the ability to do work. There are various forms of energy, such as: chemical, heat, mechanical, electrical, nuclear and so on. Mechanical energy is of two forms: kinetic and potential. Potential is energy of position while kinetic is energy of motion. One form of energy can be changed into another. Take waterfall for example. When water falls from its raised position, energy changes from potential to kinetic. In case of hydroelectric station the energy of falling water is used to drive turbines, the latter turn electric generators, these generators produce electric energy. Thus mechanical energy of falling water is turned into electric energy. The electric energy in its turn may be transformed into any other necessary form.

Michael Faraday
Michael Faraday was bom in 1791 in a small village near London. Since childhood he assisted his mother in providing for the family. One time while learning the art of bookbinding Faraday used his spare time by reading some of the books that passed through the shop. He was particularly interested in works on science, and in connection with his reading he began performing simple experiments. In 1812 Humphry Davy helped Faraday to become an assistant at the laboratory at the Royal Institute. Davy encouraged him to begin original investigations initially in chemistry and then in electricity. From 1821 he became interested in electromagnetism and made some unsuccessful experiments. His failure did not cut his interest; on the contrary he decided to study the phenomenon thoroughly by reading what had been done by others and by repeating his own experiments. In the course of these experiments, he observed that, when the magnetic pole was brought near the wire, "the effort of the wire is always to pass off at right angles from the pole". On passing a current through the wire, it revolved around the magnet. In the summer of 1831 after the year of patient experiments he discovered the electromagnetic induction and created the first electric motor. Next Faraday turned his attention to proving that electricity whatever may be its source in identical in its nature. He found that electricity frim a friction machine would deflect a galvanometer and would cause chemical decomposition. Ibis led him into the field of electrolysis. His having found that some substances were conductors, while the others were nonconductors contributed much into the field of electricity science. The world of science also knows of his having investigated the diffusion of gases through solids.

Kepler.
Kepler discovered some remarkable but simple law regarding planetary motion. He found each planet goes around the sun in a curve called an ellipse. An ellipse is not just an oval, but it is a very specific and precise curve that can be obtained by using two tracks, one at each focus. If we want to put it more mathematically it is a focus of all points the sum of whose distances is a constant.
Kepler's second observation was that planets do not go around the Sun at a uniform speed, but move faster when they are nearer the Sun and more slowly when they are father from the Sun, His third law says that orbital periods are proportional to the 3/2 power of the orbit size.

Having been discovered at the end of the 19th century radioactivity became a major step in the development of the science of the atom structure. It was Becquerel who found that the compounds of uranium being placed on a photographic plate covered with black paper emitted radiations. It was discovered that the property of emitting penetrating radiations is not confined to uranium and its compounds. Some other minerals had the same property. Having discovered radium and polonium Marie and Pierre Curie proved they were radioactive elements the radioactivity of which turned out to be several million times higher than that of uranium. Radium and other radioactive substances continuously emit energy. Having discovered the phenomenon of radioactivity they started working at the problem of the nature of radiation in radioactive substances. Ernest Rutherford, the great British physicist, honorary member of the USSR Academy of Sciences, was the first to solve the problem. In 1899 he discovered alpha and beta radiation of radium. He was the first to make an experiment in fissioning an atomic nucleus. Rutherford suggested that radioactivity was the result of atomic decay. He found out that a part of atoms of a radioactive substance disintegrated due to an unknown reason. They exploded with alpha and beta particleis constituting the products of the decay. Having started the phenomenon more profoundly he came to the conclusion that some radioactive substances disintegrate very slowly, others very quickly. While disintegrating certain radioactive substances emit electrons (beta particles). They are produced m the process of atom disintegration. Having yielded an electron some of the nucleus turn into a proton.

TextB. Alessandro Volta.
The discovery of the electric current was made possible thanks to Alessandro Volta after whom the unit of electric pressure, the Volt, was named. Volta was born in Como, in Italy, February 18, 1745. Being a teacher of physics in his home town, he got interested in many physical phenomena. His works were so important that he was invited to work to the University of Pavia, his great discovery being made there. He was also invited to Paris to lecture on the newly discovered chemical source of continuous current. Having returned to Gomo in 1819 he continued his investigations there for the rest of his life. He took great interest in Galvanr's researches. Being interested in his experiments he began carrying on similar experiments, finding out that electric source was the result of the contact of dissimilar metals. He spent the next few years trying to invent a source of a steady continuous current. The year 1800 is a good date to be remembered: for the first time in the world's history a steady continuous current was generated.

Masers and Lasers.
The devices known as masers and lasers serve as amplifiers and generators of radiation, their common characteristic being conversion of atomic energy to electromagnetic radiation. This is achieved by means of the process known as stimulated emission of radiation. The wavelength of the emitted radiation being 1 cm, we speak of microwave amplifies or masers. Instruments which generate visible radiation are called optical masers or lasers. The history of the evolution of these devices may be divided into some periods. The first period that started in 1916 and ended in 1953 was the period of the discovery of the stimulated emission process. The second period called maser period begins with" the publication of the articles by Basov and Prokhorov, the latter giving a detailed theoretical explanation of the use of molecular beams in microwave spectroscopy. Detailed calculations having been made by these two scientists, the quantative conditions for the operation of a microwave generator were found. So, the maser period extends from 1954 to 1960. During this period many masers were constructed for application in radio astronomy and as components of radar receivers. A lot of scientists being engaged in laser and maser work at this time, many new laser types were discovered, the first ruby laser by Maiman appearing in 1960, opening the laser period. Lasers made possible carrying out experiments in optics. Laser applications having increased, new developments in laser field are in demand. Nowadays laser application can be found in medicine, communications, geophysical exploration, military and metal technology.

The laser (Light Amplification by Stimulated Emission of Radiation) is closely related to the maser. But it is simplier in construction and therefore is more widely used, semiconducter lasers being most notable among many new laser types. In these lasers, electrical energy is directly converted into radiation. Laser application have also increased. Lasers are absolutely necessary for experiments requiring really high intensities in narrow spectral regions. The potential importance of these applications continues to stimulate new developments in the laser field.
The awarding of the 1964 Nobel prize in physics to Basov, Prokhorov and Townes was a recognition of the importance of the achievements in quantum electronics.

History of the Thermometers.
The very first step in the development of heat engineering made it necessary to find a device to indicate temperature and to measure its changes. As is well known the thermometer is the very instrument to serve this purpose. The word comes from two Greek words, namely "thermos" meaning "warm" and "measure" meaning "meter", that is a measuring instrument. As earlier as 1602 Galileo invented an air thermometer. It consisted of a glass bulb containing air and connected to a glass tube; the latter being immersed into a colored liquid. Gallileo's air thermometer was not sensitive to all changes of atmospheric pressure. The type of thermometer familiar to everyone at present was first put into general use as early as 1654. To make these first instruments was not an easy thing at all. The most difficult problem of all was to mark the degrees on the thermometer that is to graduate the scale. At last it was decided to take two fixed points and to divide the interval between them into the same number of degrees. In 1701 Isaak Newton, the famous British scientist, constructed a scale in which the freezing point of water was taken as zero and the temperature of the human body as 12'. Some time later the German physicist Fahrenheit proved that the temperature of boiling water was always the same at the same atmospheric pressure. It might therefore be used as a second fixed point instead of the temperature of the human body. As for the liquid used it was mercury which has been mostly employed since that time.
On the Fahrenheit scale the boiling point of water is taken as 212' and the freezing point as 32'. This scale is mainly used in English-speaking countries. In Europe the Centigrade scale is most popular.

Cooperation in Space.
A little over 70 years ago, when the idea of space flights was considered to be the product of imagination, the great Russian scientist Konstantin Tsiolkovsky published his book "Outside the Earth". It was supposed to be only a science-fiction novel written by someone who lived and taught in a small provincial town of Kaluga. Nobody believed the ideas described in the book to be realized in future. Ears passed and Tsiolkovsky's ideas proved to have been used in studying space and constructing rockets Many pages of his book were devoted to mternationalism. His imaginary spaceship described in the book was inhabited by scientists from all over the world. Each one of them appeared to be highly competent in the particular field, and all of them taken together formed a friendly crew. Now the time has come when this dream was realized. The cosmonauts of different countries exercise mutual scientific programmes in space. Ten countries are known to have b
