Novosibirsk (Unit 8)

Natural science is the main characteristic feature distinguishing the present civilization from the other civilizations in the past. From its early beginning in the sixteenth century the developments of science have influenced the course of western civilization more and more until today it plays a most dominant role. It is not much of exaggeration to say that we live in a world that materially and intellectually has been created by science.

The point is easy to illustrate on the material level. One merely needs to mention the telephone, the radio, the television, the automobile, and the airplane, or any of the countless devices invented by the application of science. There is hardly an article used in the homes, in the places of work, or in the places of enjoyment that has not been modified by technology based on science. The means of communication that bind the continents into a single community depend on scientific know-how, without modern sanitation it would be impossible to have large centres of population; without modern industry and agriculture, it would be impossible to feed, to clothe and to provide the "abundant life" to this large population.

There is, however, another part of the story less obvious and less well known, but far more important. It is a story of expanding intellectual horizons - the impact of science on the mind of a man. Fundamentally, science is an intellectual enterprise, an attempt to understand the world in a particular way. All the developments mentioned are but the results, the outcomes of this intellectual activity.

Over the past 150 years the range of human knowledge has been doubled every 12 or 15 years. In 1930 man knew 4 times as much as he did in 1900; by 1960 his knowledge had grown sixteenfold, and by the year 2000 it can be expected to be a hundred times what it had been a century previously.

The second part of the twentieth century has brought a number of technical innovations which are still very young but which are taken so much for granted that it is as if they have always existed.

In the 50-ies of the running century hardly anyone would probably have believed that we should be able to sit at home and watch astronauts walking in space or that people could be kept alive by the heart of a dead man.

The transistor was not invented until 1948. This piece of electronic equipment found wide use in space technology, computers, transistor radios, medical instruments, television sets - in fact, wherever precise control and modulation of electrical signals was required, however, the invention of ICs (integrated circuits) in 1958 brought in a new era of change in the field so fundamental, that it already has the characteristics of a second industrial revolution.

A mere 12 years separated the launching of the satellite Sputnik I in 1957 and man's first landing on the Moon in 1969. The first long-term orbital station Salyut launched in 1971 opened a new era in space research, providing the possibility of conducting investigations in the field of astrophysics, space technology, medicine, biology, etc under conditions inconceivable on the earth. Another period of 10 years and in 1981 we could witness the launching of a typically new cosmic vehicle - the Shuttle.

It is not difficult to continue with other examples but the point is clear. Events such as these are characteristic of the rate of technological development in the second half of the 20th century. They suggest that the technological innovations we are to experience during the next 20 years to come may well surpass our wildest fantasies and today's tomorrow may well become tomorrow's the day before yesterday. Science occupies a central position in modern society. It dominates man's whole existence. Research and innovations in technology should improve society's living and working conditions and remedy the negative effects of technical and social changes.

Recent developments of nuclear weapons, satellites, space platforms and intercontinental ballistic missies have attracted and rightly so, public attention throughout the world. They make wars of annihilation possible and forcily thrust upon the necessity of coming to an understanding with the other nations. It is not merely a matter of peace, but, rather, poses the question of the very survival of the human race.

Pure science - considered only for its own nature as a skill or exercise of the mind;

Physical sciencies: physics, mechanics, chemistry, pharmacology, geology, meteorology;

Master's Degree (M. A.; M. Sc.) - there has been an increasing tendency to make the Master's Degree an advanced examination degree, awarded after a year's postgraduate study, rather than a degree by thesis. This degree doesn't correspond to any Russian degree.

Doctorate. This degree is called in full Doctor of Philosophy, but is usually shortened to Ph. D. The name is the same for all faculties, and one may have a Ph. D. in English, Mathematics, or Geography. A Ph. D. is awarded on acceptance of a thesis which must be an original contribution to knowledge, that is, contain new information on scientific problems. Research for this degree usually takes about 3 years.

Senior Doctorate - these degrees are much higher than the Ph. D. However, they differ from the latter in that they do not involve (do not require) the writing of a thesis. A person wishing to apply for such a degree submits his published works to a board, or committee, who then decide if these works justify (deserve) the award of the degree.

VI. Read the text and find some more pictures of Academgorodok. Describe the picture.

In a very short time modern laboratories and attractive housing estates with all modern conveniences had sprung up in a picturesque birch wood. Siberian scientists are working on a vast variety of problems from genetics to archaeology, from permafrost to trapping, from cybernetics to economics. They have many important discoveries to their credit in nuclear physics, mathematics, mechanics and experimental medicine.

1. Technological progress has brought great changes in our social and economic organization.

2. Men of intelligence and good will are deeply concerned about the problem of directing the power of science.

4. The curiosity of scientists is directed to find relationships and connections between all kinds of things that occur in nature.

THE MEETING OF THE PRESIDIUM OF SIBERIAN DIVISION OP THE USSR ACADEMY OF SCIENCES.

4. We know exactly that there is biological life in our universe besides the earth.

5. The greatest achievements of medical knowledge and care have improved human happiness.

Today we can name many new devices which substitute manual methods of writing, calculating, even carpet beating or washing the linen. The great role is played today by computers. Can you prove that fact?

Imagine you have received the task to make an open lecture entitled "Science and Society". What problems can you discuss in it?

Many people all over the world are interested in the processes which are taking place in this country and they are eager to know about the development of Russian science. You are correspondents of BBC. What questions would you ask Russian scientists?

A great deal impresses the visitors, but perhaps nothing so much as the magnificent group of scientific institutes founded by the Siberian Branch of the U.S.S.R. Academy of Sciences near Novosibirsk.

A trip by bus from Novosibirsk to Akademgorodok is indicative of concentration of scientific institutions. The driver announcing the stops will call out: «Thermophysics», which means that the bus has arrived at the institute conducting research on heat and mass transfer and new problems of energetics. The next stop is «Chemistry», that is, one of the five chemical institutes of the center, then come «The computer centre», "Nuclear physics", «Hydrodynamics» and "Economics and industrial organization". One doesn't see much from the window of a bus. That's why we invite you to have a walk around the township and see for yourself what is going on in the Town of Science. Akademgorodok has one more specific feature — it is one of the few towns in the world built right in the middle of the forest. The closeness of the town to Novosibirsk, a large cultural centre, is an additional blessing. Actors of the best Siberian theatres often visit the town and scientists see the plays, operas, ballets and other performances, and stars on tour also rarely miss the town.

There are cinemas, clubs, shops and cafes like in every other town. The difference is that you can walk in age-old forest just a few steps away from your home. Scientific conferences and symposiums are held in the halls of the Scientists' House, heated debates often take place in its cosy rooms. Exhibitions of scientific literature, devices and equipment both Russian and foreign are often organised here. In the evenings there are soires, shows, films. The house has a collection of paintings numbering over 3.000 canvases.

Next to the residential districts is the Golden Sandy Beach of the Ob Sea with yachts ploughing its waters. The children are playing in creches and kindergartens, are studying at schools while their parents are working in numerous laboratories, research institutes, cultural establishments. Akademgorodok's club of young technicians repeatedly won prizes in Regional and Republican competitions.

Every summer Akademgorodok is visited by a noisy crowd of schoolchildren — the winners of the All-Siberia mathematics contests.

«No scientists without pupils» — such is the motto the Siberian Branch of Academy of Sciences has adopted.

II. Collect ideas to help people to change their attitude and behaviour. Discuss what you should use for school work, what you could get for a party/barbecue, how to save energy at home, how to avoid producing too much rubbish. Some of your ideas can be crazy. Remember that inventors were often considered to be crazy when they developed their ideas and explained them to others.

The Royal Swedish Academy of Sciences has decided to award the 1978 Nobel Prize for Physics in two equal parts:

one to Professor Pyotr Leonidovich Kapitsa, Institute of Physical Problems, USSR Academy of Sciences, Moscow, for his basic inventions and discoveries in the area of low-temperature physics;

and the other, to be shared equally between Dr Arno A. Penzias and Dr Robert W. Wilson, Bell Telephone Laboratories, Holmdel, New Jersey, USA, for their discovery of cosmic microwave background radiation.

Pyotr Leonidovich Kapitza was born in Kronstadt, Russia, in 1894. He graduated from the Polytechnical Institute, Petrograd in 1919, and had taught electrical engineering at the Physicotechnical Institute in Petrograd for two years when he was selected to join a scientific commission to the University of Cambridge, England.

In 1921 Kapitsa was sent to England on Lenin's instructions to renew scientific contacts. There he worked in the famous Cavendish Laboratory headed by Rutherford. In 1929 Kapitsa was elected a member of the Royal Society for his outstanding scientific work in the production of large magnetic fields.

In 1934 he returned to Moscow where he organized the Institute for Physical Problems at which he continued his research on strong magnetic fields, low temperature physics and cryogenics.

During World War II Kapitsa was engaged in applied research on the production and use of oxygen, and he found an efficient way to produce large quantities of liquid oxygen that proved crucial to the wartime soviet steel industry.

Kapitsa's research on high-power microwave generators in the late 1950s turned his interests to controlled thermonuclear fusion, about which he published a series of papers beginning in 1969.

He was one of the founders of the Moscow Physico-Technical Institute (MFTI), and the editor-in-chief of the Journal of Experimental and Theoretical Physics.

In the 1960s Kapitsa was one of the Soviet scientists who campaigned to preserve Lake Baikal from industrial pollution. He was a member of the Soviet National Committee of the Pugwash movement of scientists for peace and disarmament.

All objects and matter consist of small particles - atoms and molecules - that are in constant motion. The temperature of the matter or body is dependent on the intensity of this so-called heat movement. When the movement is halted, the temperature of the body drops to absolute zero.

Absolute zero, the lowest temperature theoretically possible, is characterized by complete absence of heat, at approximately -273.16° C, or zero degree on the Kelvin scale (0 K). At this temperature matter would possess zero entropy and maximum molecular order, the volume of an ideal gas would vanish, and a thermodynamic heat engine would operate at 100 percent efficiency. Absolute zero cannot be reached experimentally, although it can be closely approached. Special procedures are needed to reach very low, or cryogenic, temperatures.

Low-temperature physics is called cryogenics. The word is derived from the Greek kryos, meaning "icy cold." Cryogenics deals with the properties of materials at temperatures immediately above the absolute zero point. It has been shown that at these temperatures many kinds of materials acquire radically different properties. Many metals and alloys, for instance, become what is known as superconductive.

The first Nobel Prize in the area of low-temperature physics was given in 1913 to Kamerling-Onnes for his investigations on the properties of matter at low temperatures, which led to the production of liquid helium. This substance has since become one of the most useful means for attaining low temperatures.

In 1934, Kapitsa constructed a new device for producing liquid helium, which cooled the gas by periodic expansions. For the first time, a machine had been made which could produce liquid helium in large quantities without previous cooling with liquid hydrogen. This heralded a new epoch in the field of low-temperature physics.

In the 1920s, it had been found that when liquid helium was exposed to a temperature of less than 2.3 degrees above absolute zero, it was changed into an unusual form, which was named He II, or helium two. By 1938, Kapitsa was able to show that He II had such great internal mobility and negligible or vanishing viscosity, that it could better be characterized as a superfluid. During the next few years, Kapitsa's experiments on the properties of He II indicated that it is in a macroscopic quantum state, and that He II is therefore a quantum fluid with zero entropy, i.e., that it has a perfect atomic order.

As a result of his remarkable experimental and technical abilities, Kapitsa has played a leading role in low-temperature physics for a number of decades. He has also shown an amazing capacity to organize and to lead work: he established laboratories for the study of low temperatures in both Cambridge, United Kingdom and Moscow. Kapitsa's discoveries, ideas and new techniques have been basic to the modern expansion of the science of low-temperature physics.

Cryogenics has several practical applications. Among the many important industrial applications of cryogenics are the large-scale production of oxygen and nitrogen from air. The oxygen can be used in a variety of ways, for example, in rocket engines, for cutting and welding torches, for supporting life in space and deep-sea vehicles, and for blast furnace operation. The nitrogen goes into the making of ammonia for fertilizers, and it is used to prepare frozen foods by cooling them rapidly enough to prevent destruction of cell tissues. It can also serve as a refrigerant for transporting frozen foods. Cryogenics has also made possible the commercial transportation of liquefied natural gas.

Cryogenic surgery, or cryosurgery, is being used in eye surgery, in which a freezing probe is briefly applied to the outside of the eye to repair a break in the retina. A similar technique has also been employed to destroy brain tumors and to arrest cervical cancer.

Without cryogenics, nuclear research would lack liquid hydrogen and helium for use in particle detectors and for the powerful electromagnets needed in large particle accelerators. Such magnets are also being used in nuclear fusion research. Infrared devices, masers, and lasers can employ cryogenic temperatures as well.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2000 to scientists and inventors whose work has laid the foundation of modern information technology, IT, particularly through their invention of rapid transistors, laser diodes, and integrated circuits (chips).

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2003 "for pioneering contributions to the theory of superconductors and superfluids" jointly to

This year's Nobel Prize in Physics is awarded to three physicists who have made decisive contributions concerning two phenomena in quantum physics: superconductivity and superfluidity. Superconducting material is used, for example, in magnetic resonance imaging for medical examinations and particle accelerators in physics. Knowledge about superfluid liquids can give us deeper insight into the ways in which matter behaves in its lowest and most ordered state.

Graduated from the Physics Faculty of Moscow State University in 1938, defended candidate's (Ph.D.) dissertation in 1940 and doctor's dissertation in 1 942. From 1940 up to the present time - work in P.N. Lebedev Physical Institute of the Russian Academy of Sciences (from 1971 to 1988 - Head of I.E. Tamm Theory Department, at the present time - Adviser of the Russian Academy of Sciences). Since 1945 - part time - professor of Gor'ky State University and from 1 968 to the present day - part time - professor of Moscow Institute for Physics and Technology.

Author of several hundred scientific papers and a dozen of books devoted to physics and astrophysics.

The 2003 Nobel Prize in Physics Laureate.

Superconductivity is a low-temperature phenomenon in which a material loses all electrical resistance when it is cooled to a temperature near absolute zero. This unusual behavior was discovered in 1911 by a Dutch physicist, Heike Kamerlingh Onnes. In experiments to measure the resistance of frozen mercury, he discovered that the resistance vanished completely at a temperature of 4.15 К (-289 degrees C).

Vitaly Ginzburg and Alexei Abrikosov, have made decisive contributions to our understanding of how superconductivity and magnetism can coexist. In the 1950s V. Ginzburg together with Lev Landau formulated a theory that could describe how superconductivity disappears at certain "critical" values of electrical current and magnetic fields, in more detail than before. They introduced a measure for the order among electrons, which they called the superconducting order parameter. Guided by a deep physical intuition they went on to formulate mathematical equations whose solution determines the order in a superconductor. They found a close correspondence with what had been measured for superconductors known at the time. It is worth pointing out that the reasoning behind this Ginzburg-Landau theory was of such general validity that it is used today to gain new knowledge in many of the subfields of physics.

The discovery of better superconducting compounds is a significant step toward a wider spectrum of applications, including faster computers with larger storage capacities, nuclear fusion reactors in which ionized gas is confined by magnetic fields, magnetic suspension of high-speed ("Maglev") trains, and perhaps most important of all, more efficient generation and transmission of electric power over long distances.

Superfluidity is a state of matter characterized by the complete absence of viscosity, or resistance to flow. The term superfluidity is applied primarily to phenomena observed in liquid helium at very low temperatures, but the term is also sometimes used to refer to the frictionless flow of electrons in certain metals and alloys at very low temperatures.

The phenomenon of superfluidity was discovered in 1937 by the Russian physicist Peter Kapitza. He observed that liquid helium, when cooled below 2.17 К (-270.98° С), could flow with no difficulty through extremely small holes, which liquid helium above that temperature cannot do. He also noticed that on the walls of its container superfluid helium formed a thin film (approximately 100 atoms thick) that flowed against gravity up and over the rim of the container.

Superfluidity can be explained using the theory of quantum mechanics. It occurs when large numbers of atoms or molecules are cooled, in a process known as "condensation", so that they occupy the same quantum energy state. The condensed atoms will therefore interact with each other and their surroundings according to exactly the same physical laws, and, when distributed evenly throughout the normal liquid atoms, create unusual properties such as superfluidity.
