Did you know that any straight-line drawing on paper can be folded so that the complete drawing can be cut out with one straight scissors cut? That there is a planar linkage that can trace out any algebraic curve, or even 'sign your name'? Or that a 'Latin cross' unfolding of a cube can be refolded to 23 different convex polyhedra? Over the past decade, there has been a surge of interest in such problems, with applications ranging from robotics to protein folding. With an emphasis on algorithmic or computational aspects, this treatment gives hundreds of results and over 60 unsolved 'open problems' to inspire further research. The authors cover one-dimensional (1D) objects (linkages), 2D objects (paper), and 3D objects (polyhedra). Aimed at advanced undergraduate and graduate students in mathematics or computer science, this lavishly illustrated book will fascinate a broad audience, from school students to researchers.

Within these covers are stories about a group of risk-takers and adrenaline junkies who lived a life of stimulating and challenging activity. It is a rollicking adventure account of men who chose awilderness avocation and lifestyle in lieu of comfort and leisure for their relaxation. This is also a travelogue about much of the backcountry of this nation. Their journeys into these wilderness areas lasted over twenty years comprising some seventy expeditions into places like the Everglades, Okefenokee Swamp, Appalachian Trail, Pesidential Range, and the desert of Joshua Tree. Learn about these locations and other backwoods areas, primarily in the mountain states of Colorado, Idaho, New Mexico, Montana, Utah, and Wyoming. Read about these unusual people and the physical trials they put their aging bodies through as they pursued their passion, searching for refuge from their work, and adventure in their lives to help calm their craving for fun and new experiences. Importantly, they wanted to be explorers and to see what was over the horizon. Their interest level had no valley and no summit. It was limitless. They were not purists in the sense of following the conventional standards of "roughing it" in the wilderness. Instead, they did it their way. They were the real thing and enjoyed living on the edge. Not many people do. There is humor, philosophy, lessons on field-craft, and dubious judgment noted in their journeys. These should appeal to all readers with similar inclinations despite age or gender. I am thankful to have been a member of this group, and wish we could do it again. We would try, if we had the stamina.

Liminality has become a key concept within the social sciences, with a growing number of publications devoted to it in recent years. The concept is needed to address those aspects of human experience and social life that fall outside of ordered structures. In contrast to the clearly defined roles and routines that define so much of industrial work and economic life, it highlights spaces of transition, indefiniteness, ambiguity, play and creativity. Thus, it is an indispensable concept and a necessary counterweight to the overemphasis on structural influences on human behavior. This book aims to use the concept of liminality to develop a culturally and experientially sensitive psychology. This is accomplished by first setting out an original theoretical framework focused on understanding the ‘liminal sources of cultural experience,’ and second an application of concept to a number of different domains, such as tourism, pilgrimage, aesthetics, children’s play, art therapy, and medical diagnosis. Finally, all these domains are then brought together in a concluding commentary chapter that puts them in relation to an overarching theoretical framework. This book will be useful for graduate students and researchers in cultural psychology, critical psychology, psychosocial psychology, developmental psychology, health psychology, anthropology and the social sciences, cultural studies among others.
