The beauty of the theoretical science is that quite different physical, biological, etc. phenomena can often be described as similar mathematical objects, by similar differential (or other) equations. In the 20th century, the notion of 'theory of oscillations' and later 'theory of waves' as unifying concepts, meaning the application of similar methods and equations to quite different physical problems, came into being. In the variety of applications (quite possibly in most of them), the oscillatory process is characterized by a slow (as compared with the characteristic period) variation of its parameters, such as the amplitude and frequency. The same is true for the wave processes.This book describes a variety of problems associated with oscillations and waves with slowly varying parameters. Among them the nonlinear and parametric resonances, self-synchronization, attenuated and amplified solitons, self-focusing and self-modulation, and reaction-diffusion systems. For oscillators, the physical examples include the van der Pol oscillator and a pendulum, models of a laser. For waves, examples are taken from oceanography, nonlinear optics, acoustics, and biophysics. The last chapter of the book describes more formal asymptotic perturbation schemes for the classes of oscillators and waves considered in all preceding chapters.

This book is written in a lucid and systematic way for advanced postgraduates and researchers studying applied mathematics, plasma physics, nonlinear differential equations, nonlinear optics, and other engineering branches where nonlinear wave phenomena is essential.In sequential order of the book's development, readers will understand basic plasmas with elementary definitions of magnetized and unmagnetized plasmas, plasma modeling, dusty plasma and quantum plasma. Following which, the book describes linear and nonlinear waves, solitons, shocks and other wave phenomena, while solutions to common nonlinear wave equations are derived via standard techniques. Readers are introduced to elementary perturbation and non-perturbation methods. They will discover several evolution equations in different plasma situations as well as the properties of solitons in those environments. Pertaining to those equations, readers will learn about their higher order corrections, as well as their different forms and solutions in non-planar geometry. The book offers further studies on different types of collisions between solitons in plasma environment, phenomena of soliton turbulence as a consequence of multi-soliton interactions, properties of large amplitude solitary waves which are discovered via non-perturbative Sagdeev's Pseudopotential Approach, as well as the speed and shape of solitons. Finally, the book reveals possible future developments of research in this rich field.

Anarchy, Geography, Modernity is the first comprehensive introduction to the thought of Elisée Reclus, the great anarchist geographer and political theorist. It shows him to be an extraordinary figure for his age. Not only an anarchist but also a radical feminist, anti-racist, ecologist, animal rights advocate, cultural radical, nudist, and vegetarian. Not only a major social thinker but also a dedicated revolutionary. The work analyzes Reclus’ greatest achievement, a sweeping historical and theoretical synthesis recounting the story of the earth and humanity as an epochal struggle between freedom and domination. It presents his groundbreaking critique of all forms of domination: not only capitalism, the state, and authoritarian religion, but also patriarchy, racism, technological domination, and the domination of nature. His crucial insights on the interrelation between personal and small-group transformation, broader cultural change, and large-scale social organization are explored. Reclus’ ideas are presented both through detailed exposition and analysis, and in extensive translations of key texts, most appearing in English for the first time.

In this new book, Bauman examines how we have moved away from a 'heavy' and 'solid', hardware-focused modernity to a 'light' and 'liquid', software-based modernity. This passage, he argues, has brought profound change to all aspects of the human condition. The new remoteness and un-reachability of global systemic structure coupled with the unstructured and under-defined, fluid state of the immediate setting of life-politics and human togetherness, call for the rethinking of the concepts and cognitive frames used to narrate human individual experience and their joint history. This book is dedicated to this task. Bauman selects five of the basic concepts which have served to make sense of shared human life - emancipation, individuality, time/space, work and community - and traces their successive incarnations and changes of meaning. Liquid Modernity concludes the analysis undertaken in Bauman's two previous books Globalization: The Human Consequences and In Search of Politics. Together these volumes form a brilliant analysis of the changing conditions of social and political life by one of the most original thinkers writing today.

The essays in Moving Modernisms: Motion, Technology, and Modernity, written by renowned international scholars, open up the many dimensions and arenas of modernist movement and movements: spatial, geographical and political: affective and physiological; temporal and epochal; technological, locomotive and metropolitan; aesthetic and representational. Individual essays explore modernism's complex geographies, focusing on Anglo-European modernisms while also engaging with the debates engendered by recent models of world literatures and global modernisms. From questions of space and place, the volume moves to a focus on movement and motion, with topics ranging from modernity and bodily energies to issues of scale and quantity. The final chapters in the volume examine modernist film and the moving image, and travel and transport in the modern metropolis. 'Movement is reality itself', the philosopher Henri Bergson wrote: the original and illuminating essays in Moving Modernisms point in new ways to the realities, and the fantasies, of movement in modernist culture.

This book tells the story of Germany between the years 1914–1945 through the history of its sounds and noises. From the killing grounds of the Great War, passing through the roaring optimism of the 1920s, and up to the horrifying spectacle of the Nazis and the dreadful apocalypse of the Second World War, sound became the epitaph of an era that was mostly dominated by war and a global sense of crisis. Yaron Jean reconstructs and analyses these moments when sound and its meaning became history, and places them in a single study that provides a unique perspective on the history of modern Germany in one of its most turbulent centuries.

The Feminism of Uncertainty brings together Ann Snitow’s passionate, provocative dispatches from forty years on the front lines of feminist activism and thought. In such celebrated pieces as "A Gender Diary"—which confronts feminism’s need to embrace, while dismantling, the category of "woman"—Snitow is a virtuoso of paradox. Freely mixing genres in vibrant prose, she considers Angela Carter, Doris Lessing, and Dorothy Dinnerstein and offers self-reflexive accounts of her own organizing, writing, and teaching. Her pieces on international activism, sexuality, motherhood, and the waywardness of political memory all engage feminism’s impossible contradictions—and its utopian hopes.
