Ex.5: Text A. Before discussing Synergetics - the main topic of the unit - it’s worth learning the term Synergy and its basic characteristics. Read the text and present your own examples of synergy effect in our life, in other words, prove that 1+1=3! Synergy The Greek word "synergy" means, literally, "working together." In medicine, it has long been used to denote the working together of two or more drugs, or of two or more muscles acting as a joint. Applied to the human mind, "synergy" denotes the working together of the enormous variety of functions that comprise the mind, producing a new whole that is greater than the mere sum of its parts. An early pioneer in synergy was , whose concepts of anticipatory design for Spaceship Earth have inspired generations of students. Fuller emphasized the key role of synergy in producing a whole that is greater than the sum of its parts. Something new emerges - something that can exist only at the higher level of organization made possible by synergy. Indeed, synergy is of universal applicability. It can be applied not only to the human mind, but also to human groups, to organizations of all kinds, to industrial enterprises, to entire economic , to international relations, to any functioning system. Its basic characteristics of improving effectiveness by mutual aid, and of producing emergent wholes, can be recognized in every system to which it is applied.

Ex.10: Text B. Read the Text and select the appropriate heading for each part. Synergetics HEADINGS: From strict science to the philosophy of life (IV); New science of complexity (III); Various scientific schools (II); Synergetics as a field of scientific research (I).

I. The term «synergetics» was introduced by Hermann Haken, a German scholar. It has existed for over forty years already and it is widely used, but still not generally accepted. Instead, «theory of self-organization» is used as a more traditional term. Recently two other terms «studies in complexity» and «theory of chaos» have become widely used. Synergetics can be considered as a current stage of development within the traditions of cybernetics promoted by N.Wiener & W.R.Ashby. Cybernetics investigates the functioning of complex systems using an abstract model of «black box», synergetics studies some physical mechanisms of the complex structures formation, i.e. it tries to look into the «black box». Cybernetics elaborates

4 algorithms and methods of systems’ control; synergetics investigates the processes of self-control and self-organization of complex systems in the world. II. The focus of synergetic research program is to reveal general laws of self- organization and evolution which are common to processes of quite different nature: physical, chemical, biological, psychological, social. The whole history of development of the theory of self-organization shows that significant theoretical generalizations appeared from rather narrow, but fundamental scientific results. The non-equilibrium thermodynamics and the theory of dissipative structures developed by the Brussels school of the Nobel Prize winner Ilya Prigogine started with the investigation of processes in physical chemistry. The theory of cooperative behavior, developed by H.Haken, originated from the investigations of the coherent radiation of lasers. Lasers became an example of synergetics. Another example of natural science starting point for further generalizations up to a worldview one can mention the investigation of nonlinear auto-waves as early as in the 1930′s by the Russian school of L.I.Mandelshtam and A.Andronov. It’s worth mentioning the Polish-born French-American mathematician B. Mandelbrot who elaborated the so-called theory of deterministic chaos, various scenarios of transition to chaos and back. All these trends are colored in specific tones of the original disciplines, e.g. mathematics, physics, chemistry or biology. III. «Complexity» is one of the key notions in the field of synergetics. The theory deals with such questions as: 1) how does a complex structure arise; 2) what are the trends of a complex structure development; 3) how can a complex evolutionary whole be constructed? Synergetics reveals the creative role of chaos in the process of origin of complex structures and their evolution. Chaos and fluctuations on the micro-level play an essential role in determining processes at the macro-level. Complexity is closely connected with the speed (tempo) of evolution. A complex structure is an integration of structures of «different ages», i.e. structures at different evolutionary stages of development. Structures of «different ages» start to co-exist in one and the same ‘tempo-world’. The principles of integration of such «different ages» structures into an evolutionary whole structure are revealed in synergetics. IV. Synergetics goes beyond the framework of strict mathematical models and narrow applications. In the current situation of accelerated and unstable development of the world, synergetics brings us new hopes. It is an optimistic attempt to understand the principles of co-evolution of the complex social systems, to reveal causes of evolutionary crises, instability and chaos. How to manage a without harsh management is the major problem. How can we push the system in a favorable (for the subject) evolutionary path with a small influence? Synergetics can serve as a heuristic instrument in searches of answers to the questions. Text B Analysis.

Ex.15: Render the following text into English in writing, paying attention to the terms from the exercises above: Синергетика – междисциплинарное научное направление, изучающее закономерности самоорганизации открытых систем в неустойчивом необратимом состоянии. Синергетика претендует на открытие некоего универсального механизма, с помощью которого осуществляется самоорганизация как в живой, так и в неживой природе. Поэтому объектом синергетики могут быть только системы, которые удовлетворяют двум условиям: - они должны быть открытыми, т.е. обмениваться веществом и/или энергией с внешней средой; - они должны быть существенно неравновесны, т.е. находиться в состоянии, далеком от термодинамического равновесия. Важнейшим свойством самоорганизующейся системы является бифуркация. Бифуркация – это состояние системы, когда она находится перед выбором возможных вариантов функционирования и малейшие, случайные обстоятельства могут кардинально изменить направление ее дальнейшего развития закрывая возможные альтернативные пути ее изменения. (Наглядно-образное представление о точке бифуркации дает картина В.М. Васнецова «Рыцарь на распутье»))). То множество траекторий, по которым возможно развитие системы после точки бифуркации, и которые отличаются относительной устойчивостью, называются аттракторами. Синергетика определяет хаос как многоликое материальное начало, которое не только разрушает и само является продуктом разрушения, но и способствует созданию нового. Во-первых, хаос необходим для исходного структурирования нелинейной среды. Во-вторых, он способствует резонансному объединению простых структур в единую сложную структуру, согласованию темпов их эволюции, объединению «темпомиров». В-третьих, хаос может выступать как механизм переключения, смены различных режимов развития системы, переходов от одной относительно устойчивой структуры к другой.

Ex.16: You have learned that synergetics is an interdisciplinary science explaining the formation and self-organization of structures in open systems far from thermodynamic equilibrium. So, we can discuss the main characteristics of self-organizing systems: openness, nonlinearity, fluctuations, bifurcation points, of order, dissipation, attractors and chaos. Below there are eight definitions determining each term, identify the appropriate term for each definition: 1. ______Property of chaotic systems, characterized by approximation, random behavior, and unpredictability. It is the feature of a system which cannot be decomposed into parts and reassembled into the same thing.

8

2. ______In a critical phase new qualities of a self-organizing system emerge; this principle is also called order from chaos or order through fluctuation. Interactions between the components result in new properties of the system that cannot be fully predicted and cannot be found in the qualities of the components, therefore we say that a self-organizing system is more than the sum of its parts. 3. ______Small disturbances from inside the system intensify themselves and initiate the formation of order. 4. ______An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transferred into or out of the system boundary. 5. ______Once a fluctuation intensifies itself, the system enters a critical phase where its development is open, certain possible paths of development emerge, and the system has to make a choice. It’s a transitional phase from stability to instability.

6. ______Sometimes it looks like an exclusively destructive element of the world, but it’s a necessary condition for self-organization and a way of evolutionary switching.

7. ______The loss of energy from a physical system, most often in the form of .

8. ______A set of states of a nonlinear dynamic system toward which that system tends to evolve, regardless of the starting conditions of the system. They may appear, disappear or change stability through different bifurcations.

Ex.17: Now watch the video https://www.youtube.com/watch?v=3ypBqxv_tz8 and present your personal point of view towards synergetics in a written form. Ex.18: Read the text below, fill in the gaps with the words from the box and make up a summary: essential reveals self-organization destructive leads chaos creative opens up regime

Up to now many people are afraid of chaos. It did resemble a gaping abyss1 as far back as in the ancient mythology. Chaos looks like an exclusively ______element of the world. It seems that chaos ______to nowhere.

The classical view of chance is still sometimes valid. Chance (randomness) is considered as a secondary and subsidiary factor which is not of principal importance. Chances are being forgotten and washed away; they leave no traces in the course of events in nature, science, culture and society. Synergetics ______the creative role of chaos (random fluctuations) in the evolutionary processes which occur in nonlinear complex systems. There must be a certain degree of chaos and destruction in the world. Chaos and fluctuations on the micro-level play an ______role in determining the actual trends, or “aims”, of processes at the macro-level. Chaos manifests itself as a “force”, as a mechanism underlying an exit to one of several evolutionary structure-attractors. The macro- organization evolves from ______on the micro-level. Order and chaos, organization and disorganization, construction and destruction seem to be well-balanced in the world. Thus, it is senseless to resist chaos, or to tend to completely eliminate the negative, destructive elements from the world. Chaos is a necessary condition for ______. Besides this, chaos serves as a basis for integration of relatively simple evolutionary structures into more complex ones. It is a mechanism of coordinating their tempos of evolution. Chaos and fluctuations on the micro-level, can also be a way of evolutionary switching, allowing a periodical transition from one evolutionary regime to another one. Synergetics reveals the sympathetic, ______face of chaos. Chaos is, ultimately a field producing sparks of social and cultural innovations. Because chaos ______the possibility for the appearance of something completely new, an element of chaos is desirable. Synergetics allows us to understand destruction as a creative principle. “A passion for destruction is creative”, wrote the Russian philosopher M.Bakunin. Thanks to the liberation from the old and to the turn of evolutionary processes to an opposing ______, something new can emerge from the remains of the old. (From “The Complex Nonlinear Thinking” by H. Knyazeva)

Ex.19: Read the paragraphs and arrange them in their logical order: The possibility of synergetics to solve actual problems of oil and gas industry 1. Let's consider the possibility of applying synergetics to the problems of the oil and gas industry, where systems that can be considered as self- organizing, open and nonlinear are involved. 2. Summarizing these arguments, we can conclude that the use of a synergistic approach is promising for solving problems in the petroleum industry. Applying synergetics to these problems will allow looking at them in a new way and, perhaps, will open up innovative ways to solve them.

3. The problem of exploration of new fields and identifying the patterns by which oil «returns» to the mature, already developed deposits can absolutely be considered through the prism of the synergistic method.

10

4. At the moment, the petroleum industry is in a very complicated situation. This is directly related to the decline in prices for hydrocarbon resources on the world market. This is not the only problem, although it is significant. 5. In the course of field development, there are difficulties that are quite difficult to predict (for example, a water or gas breakthrough). Therefore, it is possible to consider the developed deposit as a self-organizing system in the development process, the impact on it at certain points (pumping of hydrocarbons, pumping of water/gas, processing of bottom-hole zones of wells, etc.) – as fluctuations, and the "critical" stages of development as bifurcation mechanisms, will create a clearer and more accurate model of development. This, in turn, will help solve issues related specifically to the development of deposits. 6. The processes of deposits’ formation and migration of oil in the Earth 's crust can be examined as evolution of self-organizing systems, connected with geological structure of the Earth 's crust. The presence of self- organization in the geological structure can be judged from the data of seismic exploration and geochemical analysis of the core. 7. A number of problems related directly to the construction of pipelines and transportation of hydrocarbons cannot be solved with the help of synergetics, since these processes are aimed at interacting with systems that are not self-organizing.

Grammar: Past Participle We use the past participle to make the perfect tenses and for all the passive forms. Perfect tenses (have|/has/had drilled etc.):  The company has drilled the wells. (present perfect)  They were still drilling. They hadn’t left. (past perfect) Passive (is drilled/ had been found etc.):  He was woken up by a loud noise. (past simple passive)  This deposit has just been discovered. (present perfect passive) Past Participle in a sentence has a passive meaning:  Some of the people invited to the party can’t come. (the people have been invited to the party)  Most of the goods made in the factory are exported. (the goods are made…)  When wounded, he was brought to the hospital. (when he was wounded…)

Ex.20: Determine the grammatical past participle functions and give exact Russian equivalents to the following phrases: 11

Applied to the human mind, has long been used, have inspired, can be applied, was introduced, cybernetics promoted by Wiener, is widely used, the theory developed by the Brussels school, could be constructed, when heated, is closely connected, are being revealed, accelerated development, cannot be mapped, are being forgotten and washed away, to be well-balanced, might be fully predicted, had been determined. Ex.21: Translate the sentences into Russian paying attention to Past Participle:

1. Considered from the mathematical point of view, nonlinearity signifies a certain type of mathematical equations. These contain unknown quantities in powers more than 1 or coefficients depending on properties of a system. 2. Such events are to be forgotten, they don't leave any traces in nature, science or culture. 3. The processes of simplification of organization and possible transitions to chaos are considered by synergetics only as necessary evolutionary stages. 4. An effect of localization, i.e. the structure formation, and the appearance of extremely complicated structures may be observed in these systems. 5. Certain human actions are doomed to failure. They fail because they are not in step with the inner trends of the complex system development. There are evolutionary prohibition rules which are imposed on some kinds of human action. 6. Numerous conferences and publications have been devoted to the role of synergetics for the last decades. 7. At this level we treat the liquid as being composed of little droplets with certain , density etc. 8. After the variables of the mesoscopic level characterizing the system have been fixed, equations describing their temporal change must be established. 9. Quite clearly a number of analogies between physical and chemical processes on the one hand and processes in sociology and economy on the other can be worked out. 10. “Can we exploit the insights we have gained in synergetics to either construct computers or to program them adequately? …” (by H. Haken / Synergetics and Computers) 11. Having reached specific critical values the system may become unstable and adopt a new macroscopic state.

12

12. The system can be brought by fluctuations to a critical point called ‘bifurcation’. The term ‘bifurcation’ was coined by the French mathematician and philosopher of science Henri Poincare in 1885. 13. Nowadays, systems theory — which is partial to cybernetics and feedback models — seems to have been temporarily eclipsed by “complexity theory”. 14. Working on the theory of percussion drilling, the scientists have designed a drill with a suspended pneumatic percussion. 15. If used in a business application, synergy means that teamwork would produce an overall better result than if each person within the group was working toward the same goal individually.

Ex.22: Prepare to give a 5 minute talk on one of the following topics and discuss these in class:  The history of the concept of « Synergetics»  Modern synergetics  The tasks of synergetics  The principles of the theory of synergetics  The role of synergetics https://libtime.ru/modelirovanie/sut-ponyatiya-sinergetika.html

Skills: How to read off mathematical notation in English https://stemreader.org.uk/guidelines/

Once you start to read maths aloud, you quickly discover that what seems like simple notation results in a long stream of text. For example, solve the equation ퟑ풙+ퟐ + ퟑ = ퟒ must be read as "solve the equation 3 x plus 2, all over, x minus 1, 풙−ퟏ plus 3, equals, 4" where commas have been inserted to indicate places to pause. Often a person would use pauses, stresses and variations in tone to communicate groupings and semantics within maths notation. Fractions are presented graphically with a numerator above a denominator, separated by a horizontal (or occasionally sloping line). When reading aloud a fraction, it is important that the listener understands what is contained within the numerator and denominator. The separator between them is purely a graphical representation and how it is drawn does not alter the structure of the fraction. ퟓ numerator over denominator 5 over 25. ퟐퟓ ퟏ should always be read as one half. If the denominator is between 2 and 10 then it ퟐ 1 2 3 2 may be read in its colloquial form: , , , 3 one quarter, two quarters, three 4 4 6 15 sixths, 3 and two over fifteen. 13

ퟏ ퟐ Work out × one seventh times two thirds. ퟕ ퟑ Complex fractions should be read as [numerator] all over [denominator] 풙ퟐ+ퟓ Simplify x squared + 5 all over x + 2. 풙+ퟐ

A decimal point should be read as "point". Numbers following a decimal point should be read as individual digits. "0" is spoken as zero not "oh". 0.125 zero point one two five.

When a plus sign on top of a minus sign appears between two variables or numbers then it should be read as "plus or minus". Calculate 3±5 Three plus or minus five.

Where the multiplication sign × appears as an operator between two variables or numbers then it should be read aloud as "times". Calculate 26×19 26 times 19

Where two variables or a variable and operator are displayed consecutively as an implicit multiplication, the multiplication should not be read aloud. Find the value of 3a+2b Three a plus two b.

Where the division sign ÷ appears as an operator between two variables or numbers then it should be read aloud as "divided by". It should be noted that division should not be typeset with a slash (e.g. 7/3). Work out 110÷4 110 divided by 4.

Brackets can take different forms. The most common are round brackets or parentheses ( ). It is usual within the UK education system to refer to these as brackets. Brackets can be used to denote a number of mathematical functions. When a bracket is used to group an expression or to represent an implicit multiplication then the brackets should be read aloud as "open bracket"…"close bracket". Where there is a sequence of brackets, it can be useful to pause between the "close bracket" and following "open bracket" to signify they are separate expressions. Simplify 3(x+2) + 5x 3 open bracket x + 2 close bracket + 5 x Expand and simplify (y−2) (y−5) open bracket y minus 2 close bracket, open bracket y minus 5 close bracket.

When a mathematical exponent is written as a superscript number or variable then this should be read as "to the power of". If possible pause at the end of the superscript variable, operator or expression to indicate it has finished. Where the exponent is of value 2 this may be read as «squared» followed by a pause.

14

Calculate (5×103) ÷ (2×10-2) open bracket 5 times 10 to the power of 3 close bracket, divided by, open bracket 2 times 10 to the power of negative 2 close bracket.

Where a variable, operator or expression is displayed as a subscript, then precede this with "subscript". If possible pause at the end of the subscript variable, operator or expression to indicate it has finished. It may be possible to shorten "subscript" to "sub" if the reader is award of this contraction. Given that un=5un-1+1 u subscript n equals 5 u subscript n minus 1, plus 1

Where a root is not preceded by an index, it is assumed to have an implied index of 2 and notate a square root. This should be read aloud as "square root of". Where a root is preceded by an index of 3 this should be read aloud as "cubed root of". For a root with an index with a number greater than 3, the expressions should be read starting with the index as "xth root of". If the radical index is a variable then it should be read as "x root of y". Example: ퟒ√ퟏퟒퟒ = 풙√ퟐퟖퟖ 4th root of 144 equals xth root of 288.

Where brackets are used to differentiate between the input of a function, it should be read aloud as "[function name] of [input]". Example ퟐ F (x) = − ퟑ풙 f of x equals, 2 over x squared, minus 3 x. 풙ퟐ

Where the < symbol is used it should be read as "less than". Where the ≤ symbol is used it should be read as "less than or equal to". Where the > symbol is used it should be read as "greater than". Where the ≥ symbol is used it should be read as "greater than or equal to". When a colon is used between two numbers or variables to represent a ratio it should be read aloud as "colon". Write 25: 55:15 in its simplest form 25 colon 55 colon 15.

Some examples:  x≈y x approximately equals to y.  3+7≠13 3 plus 7 not equal to 13.  Given that O is the centre of the circle and that ∠AOB=75° Angle, capital A, capital O, capital B = 75 degrees  휋5 pi [pai] to the power of five 푏  dx integral [ˈɪntɪgrəl] from a to b of the F of x dx ∫푎 퐹(푥)  52 % fifty-two per cent

Write the formula for each maths transcription: 1. Eight point two three times ten to the power of six 2. Seven over eleven 3. Ten to the power of negative six 15

4. x greater than or equal to 16 5. Square root of 20 equals 2 square root of 5 6. One half open bracket a plus b close bracket, h 7. 4 over 3 pi r to the power of 3 8. One third pi r squared, h 9. Open bracket 1 plus, i over n, close bracket to the power of n, minus 1 10. Pi to the power of three over the fifth root of x 11. Open bracket square root of 2 plus square root of 8 close bracket, squared 12. 3 a to the power of 3 b + 12 a squared b squared + 9 a to the power of 5 b to the power of 3 13. For x equals 5, solve x squared, plus 3 14. Open bracket 7 to the power of 3, times 7 to the power of 5, all over 7 to the power of 10, close bracket to the power of negative 1 15.

The Art of Complex Nonlinear Thinking Some common patterns of the complex systems behavior are revealed in synergetics/synergy. The science makes steps towards a new nonlinear/linear evolutionary worldview as well as towards the stating of the principles of complex nonlinear thinking. The most essential elements/bifurcation points of this thinking are the understanding of: 1. The constructive role of chaos in evolution/degradation, the connection of chaos on a micro-level with evolution of structures on a macro-level; 2. The laws/principles of very fast, avalanche-like processes, blow-up regimes in complex/ simple systems; 3. The existence of changing rhythms and regimes of evolutionary processes, the nonlinear dynamics of evolutionary processes/ deals; 4. The patterns of constructing complex totalities from simpler elements (or subsystems), that is the elaboration of a kind of a new evolutionary holism/interdisciplinary science; The style of thinking of classical science is subjected to radical criticism/ unanimous approval from the synergetic point of view. The style is characterized mostly by patterns of linear thinking. Some of them are not eliminated/ revealed up to the present. That's why it is worthwhile/ obligatory to consider in detail the crucial shift of paradigm/idea from linear to nonlinear thinking.
