Television

The television set is evidently the most important and popular electronic product of all time. All homes in developed countries have one or more TV sets. But in 1939 at the World’s Fair in New York a tiny 9-by-12 inch box was the center of attention for hundreds of people. They were the first to see a television set in action. Within a few days the news of television spread throughout the world. A lot of people wanted to have a look at the new invention. Everyone was interested in it. But only few people owned television sets in the next few years. When World War II broke out electronic factories that began the TV production stopped, when the war was over, TV sets began coming off factory assembly lines. At present TV communication is provided with the help of a system of artificial earth satellites so that people living in different parts of the country and all over the world and in different time zones are able to watch the central TV programs. Nowadays many countries also have a cable TV, a system using wires for the transmission of TV programs. A new technical invention, colour TV, was rapidly replacing black-and-white TV. A few years ago it became evident that the next major advance for would be digital TV. In a digital system a signal is replaced by a digital code. By the end of 1980s TV has moved to a new and the most important stage in its development since the appearance of colour TV. Technically it is called high-definition TV or Hi-Vision. This is the much higher resolution TV of the 21st century. The engineering problem that has exited almost since the first days of TV may be solved now.

Electricity

It is impossible to imagine our civilization without electricity: economic and social progress will be turned to the past and our daily lives completely. Electrical power has become universal. Thousands of applications of electricity such as lighting, electrochemistry and electrometallurgy are longstanding and unquestionable. Other devices are based on specific properties of electricity: electrostatics in the case of photocopying machine and electromagnetism in the case of radar and television. The first industrial application was in the silver workshops in Paris. The generator-a new and compact source of electricity-was also developed there. The generator replaced the batteries and other devices that had been used before. Since the beginning of the 20th century the successful development of electricity has begun throughout the world. The consumption of electricity has doubled every ten years. One of the greatest advantages of electricity is that it is clean, easily-regulated and generates no by-product. Applications of electricity now cover all fields of human activity from house washing machines to the latest laser devices. Truly electricity provides mankind with the energy of the future.

Environment Protection Must Be Global

That the problem of pollution and ecology has become the most important one for mankind is evident to all. Air and water pollution by industry is now reaching tremendous proportions. In our era it is changing from a national to an interna­tional problem. However, our scientific knowledge and technological advance­ment make it possible to eliminate it if people use good will1 and make considerable investments for that purpose. At present scientists in industrially developed countries are working on the theory of interaction of all the atmospheric and oceanic global. Increasing growth of population, industrialization and the use of resources are slowly but surely changing the global climate and water balance. It is the joint efforts of many scien­tists and special public organizations that can deal with the prob­lem and take necessary measures to protect the environment. It is still a big job and much remains to be done.

Higher Education in Russia

Higher education plays an important part in the life of any country as it provides the country with highly-qualified specialists for future development and progress. It trains people to become teachers, engineers, doctors and other professional workers. Besides, knowledge and information which comes through the mass media must also be taken into consideration. The increase of information requires new methods and new approaches to students' training and instruction. At present a new system of education is introduced in this country — a distance education system. This computer system of learning helps working professionals to continue their education while remaining at their jobs. The academic year usually lasts 9 months and is divided into two terms (semesters). The first- and second-year students obtain thorough instructions in the fundamental sciences of mathematics, physics, chemistry and drawing as well as computer engineering and a number of others. At the third year students get more advanced knowledge and begin to concentrate on their special interests, so to say, their «ma-jor» subject and take many courses in this subject. After four years students will get a bachelor's degree. About 75 percent of students receive state grants and 15 percent are sponsored by enterprises. Universities have their own students' hostels and some of them have large and excellent sport centers. Education is the way to success.

Made in space

This label «Made in Space» for industrial materials will proba­bly surprise no one in the not so distant future. Experts estimate that within a few coming years industrial production of various materials will be started in space. Conditions on board a space vehicle orbiting Earth greatly dif­fer from those on its surface. Many well-known pro­cesses go on differently due to the absence of weight. 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. Special space vehicles will also be needed for industrial produc­tion of new-generation materials. Many new and very interesting projects are planned for orbital stations. It should be said that according to the estimates of Ameri­can experts production of materials in space is to bring 60 billion dollars in the future.

Is there an End to the Computer Race?

Today the word “electronics” is in the general usage. Millions of people have electron watches. There are a lot of various radio and TV sets, video cassette recorders and CD players in our houses. In factories and plants we are surrounded with electronically controlled machines and instruments, we are carried by airplanes, ships, trains and cars with built-in electronic devices, and satellites circle the globe. In other words we are lives in an electronic world. And the center of this world is a tiny silicon plate of a few square millimeters, or a chip, as it is more commonly known. It is in the heart of every electronic device and the more cassette recorders, TV sets and computer we need. When we speak about a further developments of comps we mean not only quantity, but also higher technology and higher speed. A continuous search is going in laboratories throughout the world for more perfect, reliable and higher speed electronic circuits. At present comps capable of performing billions of operations a second are required. SC different from ordinary comp. The ordinary comp does the computations operation by operation, while the SC operates like a brain: all operations are being done simultaneously. In the next few years engineers will complete the work on comps of above 2 billion operations a second. It will take a few more years to produce a 10 billion operations comp. According to some researchers, we are close to what can be regarded as a true physical limit. But other specialists think that photons will make the operation a thousand times faster. The race is going on.
