The Chaotic Years

At this time, while nations are making efforts, mobilize their various resources to develop, Congo is driven to sink into indescribable misery. Contemporary life in Congo contrast with the potential found in this country. Indeed, there is a huge contrast between the potential in men, natural resources, basements, soil, climate, hydrography, flora fauna etc . . . , in Congo, and the life of the majority of Congolese living in the country. And in the words of MKANDAWIRE T., quoted by Professor Andr Mbata B. MANGO and MPRARISENI BUDELI, lecturer at the University of South Africa since its independence June 30, 1960, the history of the Democratic Republic of Congo has been a succession of coups, attempted secessions, attacks by foreign troops, civil wars, rebellions, plundering, authoritarian regimes, interventions of the United Nations (UN) and national conferences or dialogues. (1) Given the above, it is necessary to ask questions: Why this paradox? What constitutes the obstacle to achieve the well-being of the Congolese? In response to these questions, several answers have been proposed: the economic disintegration, lack of capital, lack of developmental political structures, etc . . . In this regard, we believe that the lack of developmental political structures would be the main cause of the chaotic situation in the Congo (DRC).Came then the major issues: how to change the policy in the Congo (DRC)? What to do to get the legitimate aspirations of the people?

Alexander's mom keeps putting stuff in her pocket and it's driving him crazy! A young kangaroo called Alexander lives in his mom, Nancy's pocket. Alexander loves his mom, but there's one thing she does that really drives him nuts. She is always putting stuff in her pocket. Alexander tries to keep things neat, but the more he tidies, the more stuff she shoves in there. When he complains, his sister calls him a baby - it's time to leave the pouch anyway. But Alexander loves it in there - it's warm and cosy and smells of mom. Then one day, it gets really bad. Twelve bobby pins, a tube of toothpaste, a bottle of water, a packet of chewing gum, two bus tickets, some keys, a toy car and a cookbook all find their way into Nancy's pouch. And that's just for starters. Finally, Alexander's had enough. 'I can't take it any more!' he shouts. 'I'm moving out!' So Alexander moves into the room next to his sister's. They make it all cosy, with a furry blanket and shelves for all his stuff. So it's just like his mom's pouch. Almost. The penultimate spread is Alexander sleeping with all his stuff strewn around him. The final spread is Nancy clearing out her pocket with a wink. It was time for Alexander to go. This is a heartwarming tale about the connection between a son and mother and a journey towards independence.

A guide to the fascinating new concept of chaotic sychronization.

This book offers an overview of solar physics with a focus on solar activity, particularly the activity cycle. It is known that solar activity varies periodically, but there are also phases of intermittency, such as the Maunder minimum, during which solar activity is very low or high over several decades. The book provides a brief introduction to chaos theory and investigates solar activity in terms of its chaotic behavior. It also discusses how intermittent phases of solar activity have affected and can affect Earth’s climate and long-term space weather, and reviews the underlying theories relating to the solar dynamo mechanism. Furthermore, each chapter includes references to scientific literature (review articles and papers) so that readers can delve deeper into the subjects covered. This richly illustrated book will appeal to a wide readership, and is also useful as a textbook for courses in solar physics and astrophysics.

A First Course in Chaotic Dynamical Systems: Theory and Experiment, Second Edition The long-anticipated revision of this well-liked textbook offers many new additions. In the twenty-five years since the original version of this book was published, much has happened in dynamical systems. Mandelbrot and Julia sets were barely ten years old when the first edition appeared, and most of the research involving these objects then centered around iterations of quadratic functions. This research has expanded to include all sorts of different types of functions, including higher-degree polynomials, rational maps, exponential and trigonometric functions, and many others. Several new sections in this edition are devoted to these topics. The area of dynamical systems covered in A First Course in Chaotic Dynamical Systems: Theory and Experiment, Second Edition is quite accessible to students and also offers a wide variety of interesting open questions for students at the undergraduate level to pursue. The only prerequisite for students is a one-year calculus course (no differential equations required); students will easily be exposed to many interesting areas of current research. This course can also serve as a bridge between the low-level, often non-rigorous calculus courses, and the more demanding higher-level mathematics courses. Features More extensive coverage of fractals, including objects like the Sierpinski carpet and others that appear as Julia sets in the later sections on complex dynamics, as well as an actual chaos "game." More detailed coverage of complex dynamical systems like the quadratic family and the exponential maps. New sections on other complex dynamical systems like rational maps. A number of new and expanded computer experiments for students to perform. About the Author Robert L. Devaney is currently professor of mathematics at Boston University. He received his PhD from the University of California at Berkeley under the direction of Stephen Smale. He taught at Northwestern University and Tufts University before coming to Boston University in 1980. His main area of research is dynamical systems, primarily complex analytic dynamics, but also including more general ideas about chaotic dynamical systems. Lately, he has become intrigued with the incredibly rich topological aspects of dynamics, including such things as indecomposable continua, Sierpinski curves, and Cantor bouquets.

There is an explosion of interest in dynamical systems in the mathematical community as well as in many areas of science. The results have been truly exciting: systems which once seemed completely intractable from an analytic point of view can now be understood in a geometric or qualitative sense rather easily. Scientists and engineers realize the power and the beauty of the geometric and qualitative techniques. These techniques apply to a number of important nonlinear problems ranging from physics and chemistry to ecology and economics. Computer graphics have allowed us to view the dynamical behavior geometrically. The appearance of incredibly beautiful and intricate objects such as the Mandelbrot set, the Julia set, and other fractals have really piqued interest in the field. This is text is aimed primarily at advanced undergraduate and beginning graduate students. Throughout, the author emphasizes the mathematical aspects of the theory of discrete dynamical systems, not the many and diverse applications of this theory. The field of dynamical systems and especially the study of chaotic systems has been hailed as one of the important breakthroughs in science in the past century and its importance continues to expand. There is no question that the field is becoming more and more important in a variety of scientific disciplines. New to this edition: •Greatly expanded coverage complex dynamics now in Chapter 2 •The third chapter is now devoted to higher dimensional dynamical systems. •Chapters 2 and 3 are independent of one another. •New exercises have been added throughout.

This book is a compilation of the review papers, expositions and some of the technical works of Leo Kadanoff, a theoretical physicist. The objective is to put together a group of not-too-technical writing in which he discusses some issues in condensed matter physics, hydrodynamics, applied mathematics and national policy. The volume is divided into four sections. The first section contains review papers on hydrodynamics, condensed matter physics and field theory. Next is a selection of papers on scaling and universality, particularly as applied to phase changes. A change of pace is provided by a series of papers on the critical analysis of simulation models of urban economic and social development. The book concludes with a series of recent papers on turbulence and chaos. Each major section has an introduction designed to tie the work together and to provide perspective on the subject matter. Contents:Fundamental Issues in Hydrodynamics, Condensed Matter and Field TheoryScaling and Phase TransitionsSimulations, Urban Studies and Social SystemsTurbulence and Chaos Readership: Condensed matter physicists, applied mathematicians and computer scientists. keywords:Order;Chaos;Critical;Statistical Mechanics;Phase Transition;Scaling;Universality;Dynamics;Turbulence;Renormalization “World Scientific has made available a collection of Leo's reviews, essays columns and commentaries which is a feast in several senses: the strategy and tactics of science, the science itself, the history of several important developments in science, and as a bonus a beautifully illustrated collection of essays on computational science. The average reader may find this, the final section of the book, most interesting, but for me the account of his discovery of scaling, for which, inexplicably, he did not receive the Nobel prize, is most intriguing. Leo's combination of verve, frankness and insight makes this a very good read.” P W Anderson Princeton Univ. “Publication of this volume will be very useful, especially for young readers. The papers disseminated over many journals acquire a new quality by being collected together. Readers not only can see a result in its final form, but also can trace its evolution.” J Fluid Mechanics “The book is an invaluable source of information and inspiration on a variety of important problems in modern physics.”EMS
