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 Buckminster Fuller, 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 systems, 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.

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
5
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
complex system 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.

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, emergence 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.
https://www.revolvy.com/topic/Self-organization&item_type=topichttps://www.revolvy.com/topic/Open%20system%20(systems%20theory)&item_type=topichttps://www.revolvy.com/topic/Thermodynamic%20equilibrium&item_type=topichttps://www.revolvy.com/topic/Thermodynamic%20equilibrium&item_type=topic
9
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 heat.
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.
11
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…)

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 𝟑𝒙+𝟐
𝒙−𝟏+ 𝟑 = 𝟒 must be read as "solve the equation 3 x plus 2, all over, x minus 1,
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. 𝟓
𝟐𝟓 numerator over denominator 5 over 25.
𝟏
𝟐 should always be read as one half. If the denominator is between 2 and 10 then it
may be read in its colloquial form: 1
4,
2
4,
3
6, 3
2
15 one quarter, two quarters, three
sixths, 3 and two over fifteen.

𝟑 one seventh times two thirds.
Complex fractions should be read as [numerator] all over [denominator]
Simplify 𝒙𝟐+𝟓
𝒙+𝟐 x squared + 5 all over x + 2.
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.

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: √𝟏𝟒𝟒𝟒
= √𝟐𝟖𝟖𝒙
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
F (x) = 𝟐
𝒙𝟐 − 𝟑𝒙 f of x equals, 2 over x squared, minus 3 x.
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.

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.
IV. Translate the following table «System Analysis versus Synergetics» in writing to show your understanding of the Unit I and Unit II.

развития и разрушения систем.
2. Придает большое значение
упорядоченности, равновесию.
2. Считает, что хаос играет важную роль в
процессах движения систем, причем не только
деструктивную.
3. Изучает процессы организации систем. 3. Исследует процессы самоорганизации.
4. Чаще останавливается на анализе
структуры систем, абстрагируется от
кооперативных систем.
4. Подчеркивает кооперативность процессов,
лежащих в основе самоорганизации и
развития систем.
