For centuries, astronomers have been interested in the motions of the planets and in methods to calculate their orbits. Since Newton, mathematicians have been fascinated by the related N-body problem. They seek to find solutions to the equations of motion for N masspoints interacting with an inverse-square-law force and to determine whether there are quasi-periodic orbits or not. Attempts to answer such questions have led to the techniques of nonlinear dynamics and chaos theory. In this book, a classic work of modern applied mathematics, Jürgen Moser presents a succinct account of two pillars of the theory: stable and chaotic behavior. He discusses cases in which N-body motions are stable, covering topics such as Hamiltonian systems, the (Moser) twist theorem, and aspects of Kolmogorov-Arnold-Moser theory. He then explores chaotic orbits, exemplified in a restricted three-body problem, and describes the existence and importance of homoclinic points. This book is indispensable for mathematicians, physicists, and astronomers interested in the dynamics of few- and many-body systems and in fundamental ideas and methods for their analysis. After thirty years, Moser's lectures are still one of the best entrées to the fascinating worlds of order and chaos in dynamics.
Personal accounts of the Great War experiences of British soldiers are well known and plentiful, but similar accounts from the German side of no man's land are rare. This highly original book vividly describes the wartime lives and ultimate fates of ten Saxon soldiers facing the British in Flanders, revealed through their intimate diaries and correspondence. The stories of these men, from front-line trench fighters to a brigade commander, are in turn used to illustrate the wider story of thousands more who fought and died in Flanders 'for King and Country, Kaiser and Reich' with the Royal Saxon Army. This ground-breaking work is illustrated with over 300 mostly unseen wartime photographs and other images, recording the German experience of the war in human detail and giving a rounded picture of how the Saxons lived and died in Flanders.
This book presents the extended Lagrange and Hamilton formalisms of point mechanics and field theory in the usual tensor language of standard textbooks on classical dynamics. The notion 'extended' signifies that the physical time of point dynamics as well as the space-time in field theories are treated as dynamical variables. It thus elaborates on some important questions including: How do we convert the canonical formalisms of Lagrange and Hamilton that are built upon Newton's concept of an absolute time into the appropriate form of the post-Einstein era? How do we devise a Hamiltonian field theory with space-time as a dynamical variable in order to also cover General Relativity?In this book, the authors demonstrate how the canonical transformation formalism enables us to systematically devise gauge theories. With the extended canonical transformation formalism that allows to map the space-time geometry, it is possible to formulate a generalized theory of gauge transformations. For a system that is form-invariant under both a local gauge transformation of the fields and under local variations of the space-time geometry, we will find a formulation of General Relativity to emerge naturally from basic principles rather than being postulated.
Cell and Tissue Destruction: Mechanisms, Protection, and Disorders provides an overview of the main mechanisms responsible for degradation in human beings and summarizes important strategies to counter these mechanisms. This book details the properties and limits of protective mechanisms, along with disturbances to systematic physiological functions. It provides examples of disease states resulting from the limits of protective systems. Three sections consider the physical and chemical reasons for destruction in living systems, protection against cytotoxic components, and the development of pathologic states. This book provides neuroscientists, cancer researchers and physicians with robust, overall coverage of the interrelated processes involved in cell and tissue destruction in living structures, and concomitant protective mechanisms and their limitations. - Describes the destruction of biological material as a consequence of the highly ordered nature of living structures - Specifies the main strategies used by cells to overcome destruction, including antioxidative systems, self-repair and growth - Highlights basic mechanisms of immune regulation - Considers the development of selected disease scenarios, from the perspective of destructive processes in cells and tissues - Details organ damage by cytotoxic components as well as septic conditions and multiple organ failure
When The Impact of Global Warming on Texas was first published in 1995, it discussed climate change as a likely future phenomenon, predicted by scientific studies. This entirely rewritten second edition presents evidence that early climate change impacts can now be observed and identifies the threats climate change will pose to Texas through the year 2050. It also offers the hopeful message that corrective action, if taken now, can avert unmanageable consequences. The book begins with a discussion of climate science and modeling and the information that can be derived from these sources for Texas. The authors follow this with an analysis of actual climate trends in the various Texas climate regions, including a predicted rise in temperatures of 5.4 degrees F (plus or minus 1.8 F) by the end of the century. This could lead to less rainfall and higher evaporation, especially in regions that are already dry. Other important effects include possible changes in El Niño (climate variability) patterns and hurricane behaviors. Taking into account projected population growth, subsequent chapters explore likely trends with respect to water availability, coastal impacts, and biodiversity. The authors then look at the issues from a policy perspective, focusing on Texas's importance to the national economy as an energy producer, particularly of oil and gas. They recommend that Texas develop its own climate change policy to serve the goals of reducing greenhouse gas emissions, increasing energy independence, ensuring regional security, and improving management of water, air, land, and wildlife.
