Applied topology is a modern subject which emerged in recent years at a crossroads of many methods, all of them topological in nature, which were used in a wide variety of applications in classical mathematics and beyond. Within applied topology, discrete Morse theory came into light as one of the main tools to understand cell complexes arising in different contexts, as well as to reduce the complexity of homology calculations. The present book provides a gentle introduction into this beautiful theory. Using a combinatorial approach—the author emphasizes acyclic matchings as the central object of study. The first two parts of the book can be used as a stand-alone introduction to homology, the last two parts delve into the core of discrete Morse theory. The presentation is broad, ranging from abstract topics, such as formulation of the entire theory using poset maps with small fibers, to heavily computational aspects, providing, for example, a specific algorithm of finding an explicit homology basis starting from an acyclic matching. The book will be appreciated by graduate students in applied topology, students and specialists in computer science and engineering, as well as research mathematicians interested in learning about the subject and applying it in context of their fields.

Updated to include a new chapter about the influence of social media and the Internet—the 20th anniversary edition of Bowling Alone remains a seminal work of social analysis, and its examination of what happened to our sense of community remains more relevant than ever in today’s fractured America. Twenty years, ago, Robert D. Putnam made a seemingly simple observation: once we bowled in leagues, usually after work; but no longer. This seemingly small phenomenon symbolized a significant social change that became the basis of the acclaimed bestseller, Bowling Alone, which The Washington Post called “a very important book” and Putnam, “the de Tocqueville of our generation.” Bowling Alone surveyed in detail Americans’ changing behavior over the decades, showing how we had become increasingly disconnected from family, friends, neighbors, and social structures, whether it’s with the PTA, church, clubs, political parties, or bowling leagues. In the revised edition of his classic work, Putnam shows how our shrinking access to the “social capital” that is the reward of communal activity and community sharing still poses a serious threat to our civic and personal health, and how these consequences have a new resonance for our divided country today. He includes critical new material on the pervasive influence of social media and the internet, which has introduced previously unthinkable opportunities for social connection—as well as unprecedented levels of alienation and isolation. At the time of its publication, Putnam’s then-groundbreaking work showed how social bonds are the most powerful predictor of life satisfaction, and how the loss of social capital is felt in critical ways, acting as a strong predictor of crime rates and other measures of neighborhood quality of life, and affecting our health in other ways. While the ways in which we connect, or become disconnected, have changed over the decades, his central argument remains as powerful and urgent as ever: mending our frayed social capital is key to preserving the very fabric of our society.

The book that inspired the movie Collapse. The world is running short of energy-especially cheap, easy-to-find oil. Shortages, along with resulting price increases, threaten industrialized civilization, the global economy, and our entire way of life. In Confronting Collapse, author Michael C. Ruppert, a former LAPD narcotics officer turned investigative journalist, details the intricate connections between money and energy, including the ways in which oil shortages and price spikes triggered the economic crash that began in September 2008. Given the 96 percent correlation between economic growth and greenhouse gas emissions and the unlikelihood of economic growth without a spike in energy use, Ruppert argues that we are not, in fact, on the verge of economic recovery, but on the verge of complete collapse. Ruppert's truth is not merely inconvenient. It is utterly devastating. But there is still hope. Ruppert outlines a 25-point plan of action, including the creation of a second strategic petroleum reserve for the use of state and local governments, the immediate implementation of a national Feed-in Tariff mandating that electric utilities pay 3 percent above market rates for all surplus electricity generated from renewable sources, a thorough assessment of soil conditions nationwide, and an emergency action plan for soil restoration and sustainable agriculture.

From the author of Guns, Germs and Steel, Jared Diamond's Collapse: How Societies Choose to Fail or Survive is a visionary study of the mysterious downfall of past civilizations. Now in a revised edition with a new afterword, Jared Diamond's Collapse uncovers the secret behind why some societies flourish, while others founder - and what this means for our future. What happened to the people who made the forlorn long-abandoned statues of Easter Island? What happened to the architects of the crumbling Maya pyramids? Will we go the same way, our skyscrapers one day standing derelict and overgrown like the temples at Angkor Wat? Bringing together new evidence from a startling range of sources and piecing together the myriad influences, from climate to culture, that make societies self-destruct, Jared Diamond's Collapse also shows how - unlike our ancestors - we can benefit from our knowledge of the past and learn to be survivors. 'A grand sweep from a master storyteller of the human race' - Daily Mail 'Riveting, superb, terrifying' - Observer 'Gripping ... the book fulfils its huge ambition, and Diamond is the only man who could have written it' - Economis 'This book shines like all Diamond's work' - Sunday Times

Insurgent cohesion is central to explaining patterns of violence, the effectiveness of counterinsurgency, and civil war outcomes. Cohesive insurgent groups produce more effective war-fighting forces and are more credible negotiators; organizational cohesion shapes both the duration of wars and their ultimate resolution. In Networks of Rebellion, Paul Staniland explains why insurgent leaders differ so radically in their ability to build strong organizations and why the cohesion of armed groups changes over time during conflicts. He outlines a new way of thinking about the sources and structure of insurgent groups, distinguishing among integrated, vanguard, parochial, and fragmented groups. Staniland compares insurgent groups, their differing social bases, and how the nature of the coalitions and networks within which these armed groups were built has determined their discipline and internal control. He examines insurgent groups in Afghanistan, 1975 to the present day, Kashmir (1988–2003), Sri Lanka from the 1970s to the defeat of the Tamil Tigers in 2009, and several communist uprisings in Southeast Asia during the Cold War. The initial organization of an insurgent group depends on the position of its leaders in prewar political networks. These social bases shape what leaders can and cannot do when they build a new insurgent group. Counterinsurgency, insurgent strategy, and international intervention can cause organizational change. During war, insurgent groups are embedded in social ties that determine they how they organize, fight, and negotiate; as these ties shift, organizational structure changes as well.

The book “Paradigm Shift for Future Tennis” starts with revelations that make obvious the limitations of today’s tennis, which does not use the laws of modern Biomechanics and Neurophysiology. The second part of the book includes a new approach to the quantum mind of a champion. It will reveal the secret weapon of Roger Federer and the blueprint of a future tennis champion. This book will expose the new tennis shot emerging from the field of sports science. It is a real weapon, which can generate a ball-speed similar to that of the first serve: the Power High-Forehand. Its aim is to generate maximal possible racket-head speed while players do not wait for the ball to bounce. This is both a tactical and psychological basis for the future tennis game. This aggressive interceptive psychology will shape the minds of future tennis champions. High racket-head speed can be achieved using the stretch-reflex, without big loops and swings. Weapons of a future tennis game will comprise of whip-like tennis serves and ground strokes, based on the stretch–reflex, and using the whole body in a fluid and integrated manner, thus manifesting a superb combination of speed and strength. Restructure your brain and apply the power of state of the art biomechanical, mathematical, medical, neural, cognitive, and quantum computational intelligence to understand the tennis of today and the future!

KELLOCK PSYCH TEXTBOOKS FOR A LOST GENERATION: MANUAL FOR SUPERIOR MEN. THE FULL COLLECTED WORKS OF KAREN KELLOCK. NEW PSYCH THEORY by Karen Kellock Ph.D., Psychology & Proverb Author. The cause of mental illness is other people: be shocked into a new world view seeing mental illness in a new light. Elite Review: "Koestler [1962] shows all discoveries blend art with science. Vivid poetic images combined with rock-solid psychology show the tyranny of groups vs. the individual: collective insanity, the contagion of lunacy. What does it take to be a champion in a sea of sharks? That’s the essence of this work. The writing is subtle, witty, clever and highly accurate. The therapy: open the book anywhere". Mansell Pattison M.D., Postdoctoral Sponsor at UCI School of Medicine, Dept. of Psychiatry. Karen Kellock received her Ph.D. from University of California, Irvine and was a postdoctoral fellow at the Medical School, Dept. of Psychiatry [NIAAA and NIMH grants] to develop a theory of System Pathology: the Debris Theory of Disease, presented in 120 books and 22 textbooks for the general public. The theory has a general formula: All disease is obstruction, all recovery is elimination, all success is attraction. The three obstructions are people, habit and food. Remove your obstruction and snap to your goals, waiting in the wings. "An integrator and discoverer. As her Ph.D. advisor it's WOW on pathological systems theory, a sudden eye-opener". Doug Chalmers, Ph.D., UCI Dept. of Psychology "Brilliance inspires thinking in new realms by debunking old myths. A true theoretician ties everything together so we can see the whole".
