Natural Quasicrystals: The Solar System’s Hidden Secrets (SpringerBriefs in Crystallography)

by Luca Bindi

This book describes the discovery of quasicrystals (icosahedral and decagonal) in an extraterrestrial rock from the Koryak Mountains of Far Eastern Russia. After a decade-long search for a natural quasicrystal, this discovery opened a new avenue in mineralogy and crystallography that could lead to further discoveries in geoscience, astronomy, condensed matter physics, and materials engineering. For the first time, minerals have been discovered that violate the symmetry restrictions of conventional crystallography. The natural occurrence of such crystals was unexpected, involving previously unknown processes. The fact that the quasicrystals were found in a meteorite formed in the earliest moments of the solar system means these processes have been active for over 4.5 billion years and have influenced the composition of the first objects to condense around the Sun. Finding quasicrystals formed in these extreme environments also informed the longstanding debate concerning the stability and robustness of quasicrystals. Recent shock experiments lend support to the hypothesis that the extraterrestrial quasicrystals formed as a result of hypervelocity impacts between objects in the early Solar system, and that they are probably less rare in the Milky Way.

Natural Questions

by Lucius Annaeus Seneca

Lucius Annaeus Seneca (4 BCE-65 CE) was a Roman Stoic philosopher, dramatist, statesman, and adviser to the emperor Nero, all during the Silver Age of Latin literature. The Complete Works of Lucius Annaeus Seneca is a fresh and compelling series of new English-language translations of his works in eight accessible volumes. Edited by world-renowned classicists Elizabeth Asmis, Shadi Bartsch, and Martha C. Nussbaum, this engaging collection restores Seneca--whose works have been highly praised by modern authors from Desiderius Erasmus to Ralph Waldo Emerson--to his rightful place among the classical writers most widely studied in the humanities. Written near the end of Seneca’s life, Natural Questions is a work in which Seneca expounds and comments on the natural sciences of his day--rivers and earthquakes, wind and snow, meteors and comets--offering us a valuable look at the ancient scientific mind at work. The modern reader will find fascinating insights into ancient philosophical and scientific approaches to the physical world and also vivid evocations of the grandeur, beauty, and terror of nature.

Natural Reflections: Human Cognition at the Nexus of Science and Religion

by Barbara Herrnstein Smith

In this important and original book, eminent scholar Barbara Herrnstein Smith describes, assesses, and reflects upon a set of contemporary intellectual projects involving science, religion, and human cognition. One, which Smith calls "the New Naturalism," is the effort to explain religion on the basis of cognitive science. Another, which she calls "the New Natural Theology," is the attempt to reconcile natural-scientific accounts of the world with traditional religious belief. These two projects, she suggests, are in many ways mirror images--or "natural reflections"--of each other. Examining these and related efforts from the perspective of a constructivist-pragmatist epistemology, Smith argues that crucial aspects of belief--religious and other--that remain elusive or invisible under dominant rationalist and computational models are illuminated by views of human cognition that stress its dynamic, embodied, and interactive features. She also demonstrates how constructivist understandings of the formation and stabilization of knowledge--scientific and other--alert us to similarities in the springs of science and religion that are elsewhere seen largely in terms of difference and contrast. InNatural Reflections,Smith develops a sophisticated approach to issues often framed only polemically. Recognizing science and religion as complex, distinct domains of human practice, she also insists on their significant historical connections and cognitive continuities and offers important new modes of engagement with each of them.

Natural Regulation of Animal Populations

by Ian A. McLaren

Surveying an area dense with conflicting observations and ideas, this volume vividly depicts the current state of knowledge as well as the great diversity of opinion in the field of population ecology.

Natural Resource Degradation and Human-Nature Wellbeing: Cases of Biodiversity Resources, Water Resources, and Climate Change

by Rashed Al Titumir Tanjila Afrin Mohammad Saeed Islam

The book addresses the gaps in the body of knowledge from two grounds. Firstly, it adds value through explaining the dynamics of natural resource governance by focusing on the particular arenas of biodiversity resources, water resources and climate change in developing country context. Secondly, it critically scrutinizes the market-centric perspectives on one hand and combines political economy questions that are generally overlooked in discussions of current resource governance framework, on the other. It develops a new framework to examine the reasons behind the degradations of natural resources to offer sustainable solutions to the problems. It shows that the natural resources have been exploited beyond sustainable limits due to the structural rigidities, embedded in, and reproduced by, fragile institutions and unequal power-sharing arrangements under the market-centric economic system. The book formulates a new understanding of sustainability in case of usage and management of natural resources by incorporating the idea of human sociality. It highlights the importance of the well-being of nature, and human beings must go side by side; one without the other is not a sustainable option. The book contains key learnings for scholars and researchers working in the field of development studies who wish to gain a deeper understanding on the sustainable natural resource governance specifically in the contexts of developing countries. For policymakers and policy advocates, the book serves as the groundwork on policies regarding biodiversity resources, water resources, and climate change, specific to the context of developing countries, providing more relevant contents in terms of laying out justification for policy objectives.

Natural Resources Deterioration in MENA Region: Land Degradation, Soil Erosion, and Desertification (Earth and Environmental Sciences Library)

by Ayad M. Fadhil Al-Quraishi Yaseen T. Mustafa

Land deterioration, drought, desertification, and water resources shrinkage threaten natural resources, negatively impacting environmental, economic, and political stability. The increasing occurrence of climate change (extremes) impacts land degradation processes, soil erosion by water and wind, and salinization. The researchers have invested several years of scientific research in natural resources deterioration, including soil degradation and erosion, land degradation, desertification, and climate changes, which are interesting enough. However, the link between science and policymaking appears to be less active as serious actions do not take fast. The eighteen chapters of this book focus more on topics related to natural resources deterioration, such as land degradation, desertification, drought, climate change, and analysis of numerous case studies. This book presents experts' overviews, study results, experiences, and knowledge of natural resources deterioration in MENA countries. It attracts researchers, experts, scholars, scientists, academics, students, practitioners, graduates, or anybody interested in land degradation, desertification, climate change, and natural hazards that fall within natural resources deterioration. Therefore, researchers keep continuing to do their investigations and produce results that convince stakeholders and policymaking to act immediately towards protecting natural resources and their sustainability.

Natural Resources Management and Sustainable Livelihoods in the Mountainous Region: Evidence, Gap and Future Strategies (Advances in Geographical and Environmental Sciences)

by Praveen Kumar Rai Ashutosh Singh Suraj Kumar Singh Bobby Beingachhi

This book explores the relationships between natural resources management, sustainable livelihoods, and integrated watershed management in the context of the mountainous region, especially in the northeastern region of India. The book also sheds light on the current state of regional issues, identifies gaps in the existing practices and proposes future policies for effective conservation and sustainable development.The environmental degradation in the northeastern region of India is basically attributed to the increasing biotic pressure on the fragile ecosystems in the absence of suitable investments and proper management practices to enhance and conserve the natural resources. Population growth and poverty on the one hand and the pressure of rising demand from wealth and consumerism on the other hand, have been exerting powerful pressure on the ecosystems. Natural resources planning and management and sustainable livelihoods through integrated watershed management is not just a technical challenge; it is also a social challenge. The book is a valuable resource for policymakers, researchers, practitioners and stakeholders involved in natural resource management, sustainable development and watershed management in the Himalayan region.

Natural Resources, Sustainability and Humanity: A Comprehensive View

by Ana Cunha Angela Mendonca Ranjan Chakrabarti

Shortly, this book is the written up-graded version of the topics discussed during the Small Meeting of the 2nd International School Congress: Natural Resources, Sustainability and Humanity, held in Braga, Portugal, 5-8 May 2010 with the diverse participation of scientists, educators and governmental representatives. The Earth hosts an immense ecosystem, colonized by millions of species for billions of years but only for a few tens of thousands of years by humans. Environmental history tells though that it was humankind that shaped the environment as no other species. History, geography, religion and politics among other reasons have differentiated populations with respect to access to safe food and water, education, health, and to space and natural resource utilization. The globalization era of trade, information and communication is shortening distances and increasing overall wealth, but, as is pointed out in this book, it is also contributing to the propagation of diseases, and to the modification or even destruction of native ecosystems by exotic invasive species. Man is the only species that has the perception of its history, evolution, of the consequences of its decisions, and that there is a future ahead. It is also the only species that has the potential to change it. This awareness can be a source of anxiety and contradictory behaviours, but it is also the key to changing attitudes towards the construction of a common sustainable home, by committed education, interdisciplinary approaches, mobilization and empowerment of people and political consonant actions.

Natural Satellites: The Book of Moons

by Ron Miller

For centuries, astronomers have placed a special interest on the other planets of the solar system. But with the advent of spacecraft and the tremendous missions undertaken by the Voyager and Cassini probes, astronomers have discovered that the natural satellites of the planets—the solar system's moons—are some of the most extraordinary places imaginable. There are moons with towering geysers, erupting volcanoes, and subterranean oceans of warm, mineral-rich water. Some of the highest mountains and deepest canyons can be found on the moons. There are moons that have shattered into pieces and then reassembled. There is even a moon where it rains rocket fuel. Recently, scientists have turned to the moons for answers in their investigations of the origins of the solar system and the evolution of life on our own planet. Featuring full-color, scientifically accurate illustrations by NASA artist Ron Miller, Natural Satellites: The Book of Moons chronicles these investigations and the questions we have yet to answer in our exploration of the solar system's moons.

Natural Science

by Immanuel Kant Eric Watkins

Though Kant is best known for his strictly philosophical works in the 1780s, many of his early publications in particular were devoted to what we would call 'natural science'. Kant's Universal Natural History and Theory of the Heavens (1755) made a significant advance in cosmology, and he was also instrumental in establishing the newly emerging discipline of physical geography, lecturing on it for almost his entire career. In this volume Eric Watkins brings together new English translations of Kant's first publication, Thoughts on the True Estimation of Living Forces (1746-1749), the entirety of Physical Geography (1802), a series of shorter essays, along with many of Kant's most important publications in natural science. The volume is rich in material for the student and the scholar, with extensive linguistic and explanatory notes, editorial introductions and a glossary of key terms.

Natural Science and Indigenous Knowledge: The Americas Experience

by Edward A. Johnson Susan M. Arlidge

How do we combine the areas of intersection between science and indigenous knowledge, but without losing the totality of both? This book's objective is to consider how Indigenous populations have lived and managed the landscape. Specifically, how their footprint was a result of the combination of their empirical knowledge and their culture. The chapters are divided into four groups: The first deals with reintegrating cultures and natural landscapes and the role of kinship and oral tradition. The second group approaches the landscape as a living university of learning and managing, discussing the ethnobotany of how to grow more responsibly, and assess and project the harvest. The third group deals with the managing of fire in an anthropogenic plant community and how to integrate indigenous agriculture in hydrology and dry regions. The fourth group consists of studies of how science and indigenous knowledge can be taught in schools using land-based studies.

Natural Secondary Metabolites: From Nature, Through Science, to Industry

by Márcio Carocho Sandrina A. Heleno Lillian Barros

This book focuses on the different compounds (polyphenols, sterols, alkaloids terpenes) that arise from the secondary metabolism of plants and fungi and their importance for research and industry. These compounds have been the backbone and inspiration of various industries like the food, pharmaceutical and others to produce synthetic counterparts. Furthermore, many of these compounds are still widely used to carry out specific functions in all these industries. This book offers a compilation of different texts from world leading scientists in the areas of chemistry, biochemistry, plant science, biotechnology which compile information on each group of secondary metabolism compounds, and their most important applications in the food, pharmaceutical, cosmetic and textile industry. By showcasing the best uses of these compounds, the chemistry behind their production in plants and fungi, this book is a valuable resource and a "go to" artifact for various audiences. The new approach this book offers, by linking research and the application of these compounds, makes it interesting as an inspiration for new research or as a hallmark of what has been done in the secondary metabolism of plants and fungi in recent years. Although this book may be technical, it is also enjoyable as an integral reading experience due to a structured and integrated flow, from the origins of secondary metabolism in organisms, to the discovery of their effects, their high intensity research in recent years and translation into various industries. Beyond learning more on their chemistry, synthesis, metabolic pathway, readers will understand their importance to different research and industry.
