The achievements of great mathematical thinkers from ancient times to the modern age are examined through engaging, accessible text. Fascinating profiles of time-measurers like the Mayans and Huygens, arithmeticians like Pythagoras and al-Khwarizmi, logicians like Aristotle and Russell, and many more. Readers can follow along on these thinkers quests to explain the patterns in the world around them and to solve a wide range of theoretical and practical problems.
Over the millennia, the drainageway we now call the Santa Cruz River has seen many ebbs, flows, and floods. Throughout its long history, the river has meandered. It has flowed on the surface. It has carved deep fissures, and it has widened and narrowed.As readers of Requiem for the Santa Cruz learn, these are events that also have taken place in historic times. Authored by an esteemed group of scientists, Requiem for the Santa Cruz thoroughly documents this river, which flows through Tucson, Arizona, as a prime example of arroyo cutting, a process where heavy rains cut down through rock to create deep channeling. Each chapter provides a unique opportunity to chronicle the arroyo legacy, evaluate its causes, and consider its aftermath. Using more than a century of observations and collections, the authors reconstruct the physical, biological, and cultural circumstances of the river's entrenchment, widening, and subsequent partial filling. Today, communities everywhere face this conundrum: do we manageephemeral rivers through urban areas for flood control, or do we attempt to restore them to some previous state of naturalness? Requiem for the Santa Cruz carefully explores the channel-change legacy, the efficacy of attempts to stabilize it, and the nascent attempts at river restoration to give a long-term perspective on management of rivers in arid lands. Tied together by authors who have committed their life's work to the study of arid-land rivers, this book offers a touching and scientifically grounded requiem for the Santa Cruz and every southwestern river"--
From five authors with over two decades of experience teaching origins together in the classroom, this is the first textbook to offer a full-fledged discussion of the scientific narrative of origins from the Big Bang through humankind, from biblical and theological perspectives. This work gives the reader a detailed picture of mainstream scientific theories of origins along with how they fit into the story of God's creative and redemptive action.
Woody wetlands constitute a relatively small but extremely important part of the landscape in the southwestern United States. These riparian habitats support more than one-third of the regionÕs vascular plant species, are home to a variety of wildlife, and provide essential havens for dozens of migratory animals. Because of their limited size and disproportionately high biological value, the goal of protecting wetland environments frequently takes priority over nearly all other habitat types. In The Ribbon of Green, hydrologists Robert H. Webb, and Stanley A. Leake and botanist Raymond M. Turner examine the factors that affect the stability of woody riparian vegetation, one of the largest components of riparian areas. Such factors include the diversion of surface water, flood control, and the excessive use of groundwater. Combining repeat photography with historical context and information on species composition, they document more than 140 years of change. Contrary to the common assumption of widespread losses of this type of ecosystem, the authors show that vegetation has increased on many river reaches as a result of flood control, favorable climatic conditions, and large winter floods that encourage ecosystem disturbance, germination, and the establishment of species in newly generated openings. Bringing well-documented and accessible insights to the ecological study of wetlands, this book will influence our perception of change in riparian ecosystems and how riparian restoration is practiced in the Southwest, and it will serve as an important reference in courses on plant ecology, riparian ecology, and ecosystem management.
In this book, a team of scholars from five universities shows how new experiments in growth management can reinvigorate land use planning and help local governments find new solutions to the problems caused by growth and change. Drawing on evidence from five states and scores of cities and counties, the authors show why the benefits of growth are not automatic. Much depends on how well states craft growth management legislation, how amply programs are funded, and how dedicated state officials are to working with localities. By building on these findings, they conclude, states and localities can improve their chances for coping successfully with land use change.
This excellent book remaps the limits and possibilities of change, clearly shifting the focus from outmoded debates on agency and structure to new practice-based discourses on agency and change. Offering readers a selective and critical review of key literature and empirical research, it will help students contextualize this complex subject area and independently evaluate future prospects for effective change agent roles in organizations Presenting an interdisciplinary exploration of competing discourses, the book uses two overarching conceptual continua: centred agency-decentred agency and systems-processes, thereby allowing a more intensive focus on agency and change. Well-written with challenging content, this book is essential reading for those interested in the origins, development and future prospects for change agency in an organizational world characterized by increasing complexity, risk and uncertainty.
In this book, the author has looked at and studied during his lifetime the many theories and beliefs of the creation of earth, our solar system, the universe, and everything in it--including all the organics, plants, animals, humans, extraterrestrials, spiritual, and other realms of existence. Included in this book are the studies of extraterrestrials that have been listed in five different categories and their influence on earth throughout history from the ancient past to the present day. The author speaks at length on the prevailing beliefs and theories of evolution, religious and ancient histories, and the ancient astronaut theorists. Included is a study of the laws of creation and life, which is truth and reality throughout the entire universe. He also speaks of the beliefs of other sects in the world today and throughout all of world history. He tells of the four different tragedies that happened in the world and our solar system in the last six thousand years--the who, how, why, and when of them. He lists the interpretations of history and prophecies that came to light and were reported in the 1950s and 1960s that seem to have been pretty much forgotten. He brings to light the misinterpretations and mistranslations of biblical history and the great many histories of the world, including the many histories of the Americas.
