Exercise 4. Comment on the following statement.
-
Every student ought to be able to read very fast.
-
One point of view: Reading requires thought; one needs time for thinking, reading ought to be a kind of dialogue with the author — this requires time; quality is more important than quantity.
-
204
-
A contrary point of view : Fast reading does not mean careless reading, nothing is left out, thinking can be very fast, fast reading is reading for meaning, it saves time (экономить) also for thinking, it is very important for a person to get a great deal of information in as little time as possible.

A Story Too Terrible To Tell
-
Three men came to New York for the first time. They took a room in a hotel. In the evening they went sight-seeing and did not come back till nearly three in the morning. The room they had taken was on the 43rd floor. «I am sorry, gentlemen», said the porter, «but the elevator does not work, there is something wrong with it. You will have to walk up to your room». This was too bad, but the men agreed to tell stories on the way up in order to kill the time.
-
By the time the first one had told his story, they had climbed up to the 11th floor. The next story kept them amused till they had reached the 31st floor. At last it was time for the third man to tell his story, but he refused. He said the story he had in mind was too terrible, he simply couldn't tell it. They continued climbing and all the time the two asked him to begin. At last they stopped and refused to go on unless he told them his terrible story. «The story I have to tell you is a short one», he said at last, «we have left the key to our room downstairs with the porter».

Прочитайте текст и найдите информацию о преимуществах применения оптических волокон в технике связи; о том, что послужило основой разработки систем оптической связи, а также о практическом применении оптической технологии. Соотнесите отмеченные в тексте факты со следующими датами: 1960, 1970, 1982 гг. Изложите эту информацию по-английски.
-
Optical Technology
-
One of the most interesting developments in telecommunication is the rapid progress of optical communication where optical
-
207
-
fibers are replacing conventional telephone wires and cables. Just as digital technologies greatly improved the telephone system, optical communication promises a considerable increase in capacity, quality, performance and reliability of the global telecommunication network. New technologies such as optical fibers will increase the speed of telecommunication and provide new, specialized in-information service. Voice, computer data, even video images, will be increasingly integrated into a single digital communication network capable of processing and transmitting virtually any kind of information.
-
It is a result of combining two technologies: the laser, first demonstrated in 1960, and the fabrication 10 years later of ultra-thin silicon fibres which can serve as lightwave conductors. With the further development of very efficient lasers plus continually improved techniques to produce thin silica fibres of incredible transparency, optical systems can transmit pulses of light as far as 135 kilometers without the need for amplification or regeneration.
-
At present high-capacity optical transmission systems are being installed between many major US cities at a rapid rate. The system most widely used now operates at 147 megabits (thousand bits) per second and accommodates 6,000 circuits over a single pair of glass fibres (one for each direction of transmission). This system will soon be improved to operate at 1.7 gigabits (thousand million bits) per second and handle 24,000 telephone channels simultaneously.
-
A revolution in information storage is underway with optical disk technology.
-
The first digital optical disks were produced in 1982 as compact disks for music. They were further developed as a storage medium for computers. The disks are made of plastics coated with aluminium. The information is recorded by using a powerful laser to imprint bubbles on the surface of the disk. A less powerful laser reads back the pictures, sound or information. An optical disk is almost indestructible and can store about 1000 times more information than a plastic disk of the same size.
-
One CD-ROM disk (650 MB) can replace 300,000 pages of text (about 500 floppies), which represents a lot of savings in databases.
-
The future of optical storage is called DVD (digital versatile disk). A DVD-ROM can hold up to 17 GB, about 25 times an ordinary CD-ROM. For this reason, it can store a large amount of multimedia software and complete full-screen Hollywood movies in different languages. However, DVD-ROMs are «read-only» devices. To avoid this limitation, companies also produce DVD rewritable drives.
-
208
-
Besides, it is reported that an optical equivalent of a transistor has been produced and intensive research on optical electronic computers is underway at a number of US companies as well as in countries around the world.
-
It is found that optical technology is cost-effective and versatile. It finds new applications every day — from connecting communication equipment or computers within the same building or room to long-distance transcontinental, transoceanic and space communications.

An Encyclopedia on a Tiny Crystal
-
Scientists have discovered that a laser beam can be effectively used to record alphanumeric data and sound on crystals. According to Russian researchers a method for recording information on crystals by means of a laser has already been developed, but advanced technologies are needed to make it commercially applicable.
-
At present researchers are looking for the most suitable chemical compounds to be used as data storages and trying to determine optimum recording conditions. Theoretically, the entire «Great Soviet Encyclopedia» can be recorded on a single tiny crystal.
-
As far back as 1845, Michael Faradey discovered that a light beam reverses its polarization as it passes through a magnetized crystal. Scientists of our day have used this phenomenon to identify crystalline materials capable of storing information. Lasers have been successfully employed to record information on and read it off.
-
No ideal data storage crystal has yet been found, but it is obvious now that the future of computer engineering lies in lasers and optoelectronics.

fact, it is becoming more and more evident that many of the problems that affect the world today cannot be solved without joining scientific efforts and material resources on a wo rid-wide scale. The exploration of space, world finance, global environment protection problems and the development of new sources of power are the examples of areas of scientific research which are so costly and complicated that it is difficult for a single country to solve them efficiently and in a short period of time. The renewal of international scientific cooperation was demonstrated in the sharing of data which were obtained by Russian, Japanese and European space probes in 1986 on Halley's comet.
-
Many countries were successfully cooperating on a programme called Intercosmos in launching a large number of vertical geophysical rockets and satellites. Space exploration programmes were being conducted between Russia and Austria, India, France, Sweden and other countries. Joint manned flights by Russian and foreign cosmonauts included citizens from numerous countries. Many international crews have worked on orbit and carried out a lot of scientific experiments,

Russian and the U.S. engineers are now working side by side on the International Space Station, the largest peacetime engineering project in history.
-
Launched from opposite sides of the world, the first International Space Station components Zarya and Unity have begun a new era of exploration as 16 nations joined their scientific and technological resources in the first truly international space program to improve life on Earth. Even before its launch, the International Space Station has opened new spheres of research on Earth by overcoming barriers of language, culture and technological differences worldwide.
-
Indeed, it represents unprecedented (беспрецедентный, беспримерный) global cooperation and trust. There is no doubt that it is the first step towards a unified «planetary civilization» that will explore space as citizens of Earth, not of individual nations.

Laser Propulsion
-
Another approach is to absorb laser light in a plasma «flame» sustained by laser light focused in the center of a flowing stream of propellant gas. Thrust levels as high as 10,000 N with a specific impulse (удельный импульс) of 1,000 sec appear achievable using hydrogen as the propellant gas. Laser power as low as 1 MW would be useful for low Earth orbit launching without relay optics. 10-100 MW lasers can launch small payloads from the ground. With up to 100 launches a day, a 20 MW launcher weighing 20 kg could place several hundred tons in orbit per year. Low-gigawatt lasers could launch multi-ton spacecraft with the same ease that present multi-gigawatt chemical rockets do. Laser rockets will have much better payload fraction since the heavy power plant is left on the ground and the higher specific impulse results in lower propellant fraction. Although gigawatt lasers are not off-the-shelf items, there is no doubt they could be built if the need were strong enough.
