Book Description
A comprehensive look at the entirety of Native American history, focusing particularly on native peoples within the geographic boundaries of the United States. The history of American Indians is an integral part of American history overall—a part that is often overlooked. History of American Indians: Exploring Diverse Roots provides a broad chronological overview of Native American history that challenges readers to grapple with the elemental themes of adaptation, continuity, and persistence. The book enables a deeper understanding of the origins and early history of American Indians and presents new scholarship based on the latest research. Readers will learn a wealth of American Indian history as well as appreciate the key role American Indians played in certain significant stages of American history as a whole. The direct connections between the events in the past and many current hot-button topics—such as race, climate change, water use, and other issues—are clearly identified. The book's straightforward, chronological presentation makes it a helpful and easy-to-read scholarly work appropriate for advanced high school and undergraduate college students.

Book Description
Where would a Cuckoo and a Lobster be found in the proximity of Cancers and Rainbows? Where would bread, unleavened or puffed up, shed light on life and sincerity in religious practice? They meet within the pages of this latest book by Teddy Donobauer. What appears natural in some aspects carries spiritual significance in many other. A butterfly not only flutters by, but cries to the soul, learn from me. The almost universal concern for the environment is on the lips of every man. And we are blamed for virtually every evil. What is not on the lips of all, is the fact that our natural environment depends on the spiritual environment which precedes it, and out of which it came. Our sins against creation started as sins against the larger environment of the Creator. It is our loss of correspondence with the Creator which has led to our disastrous behaviour in His world. Creation and the Uncreated cannot be separated from each other as that which is visible is entirely dependent on invisible realities. Creation and God cannot be separated, and every physical thing is under Spiritual laws. There are therefore two books to read. The Bible and the Creation of which the Bible speaks in a multitude of ways. What is true in the world is also true in the Spiritual world. This book explores this double message in a few chosen areas. The one-eyed visions of the naturalist must be complemented with a spiritual second eye. A stereo vision of the visible and the invisible together. Seeing with two eyes, and looking with eyes wide open on the world while it is still ours to live in. It’s salvation will still be the Creator’s business

Book Description
About the Book: It is necessary that a subject like physics is studied, learnt and taught with full comprehension of the various topics of the subject, understanding their numerous facets not only humans but also plants and functions of even bodies all around. This may require not only studying just “theoretical: aspect of physics, but learning these in practice by, for example, conducting relevant experiments where possible. When viewed in this respect, most physics books at school level, including the ones published as “text books”, fail to do full justice to the requirements of learning and teaching physics in class rooms. Many a books are obtained to ‘cover’ the prescribed syllabus under any of the well known streams such as ICSE, CBSE, SSC etc. with too cluttered contents and a horde of solved examples and exercises numbering into dozens at the end of a given chapter which make the students pore over for hours at end with the sole purpose of doing well in the board exams, obtaining marks in nineties, without fully mastering the topics. The present book whilst doing away with many drawbacks as above, has been written by describing all relevant topics of physics at high-school and board level in perspective, relating the topics to their importance in daily life, whilst conforming to various syllabi on physics and enlarging the scope where necessary. The book is structured especially for those students and teachers who have innovative mindset and who would really like to learn physics conceptually, not just to pass board exams with good ‘grades’. The book is enriched with a good number of solved numerical problems with clear step-by-step solution of each and numerous exercises at the end chapter, most question having been derived from the ICSE board exams over the past ten years or so. Contents: 1. Force, Work, Power and Energy 2. Light 3. Sound 4. Electricity and Magnetism 5. Heat 6. Modern Physics

Book Description
The near disappearance of the American bison in the nineteenth century is commonly understood to be the result of over-hunting, capitalist greed, and all but genocidal military policy. This interpretation remains seductive because of its simplicity; there are villains and victims in this familiar cautionary tale of the American frontier. But as this volume of groundbreaking scholarship shows, the story of the bison’s demise is actually quite nuanced. Bison and People on the North American Great Plains brings together voices from several disciplines to offer new insights on the relationship between humans and animals that approached extinction. The essays here transcend the border between the United States and Canada to provide a continental context. Contributors include historians, archaeologists, anthropologists, paleontologists, and Native American perspectives. This book explores the deep past and examines the latest knowledge on bison anatomy and physiology, how bison responded to climate change (especially drought), and early bison hunters and pre-contact trade. It also focuses on the era of European contact, in particular the arrival of the horse, and some of the first known instances of over-hunting. By the nineteenth century bison reached a “tipping point” as a result of new tanning practices, an early attempt at protective legislation, and ventures to introducing cattle as a replacement stock. The book concludes with a Lakota perspective featuring new ethnohistorical research. Bison and People on the North American Great Plains is a major contribution to environmental history, western history, and the growing field of transnational history.

Book Description
Using case studies from around the globe—including Mesoamerica, North and South America, Africa, China, and the Greco-Roman world—and across multiple time periods, the authors in this volume make the case that abundance provides an essential explanatory perspective on ancient peoples’ choices and activities. Economists frequently focus on scarcity as a driving principle in the development of social and economic hierarchies, yet focusing on plenitude enables the understanding of a range of cohesive behaviors that were equally important for the development of social complexity. Our earliest human ancestors were highly mobile hunter-gatherers who sought out places that provided ample food, water, and raw materials. Over time, humans accumulated and displayed an increasing quantity and variety of goods. In households, shrines, tombs, caches, and dumps, archaeologists have discovered large masses of materials that were deliberately gathered, curated, distributed, and discarded by ancient peoples. The volume’s authors draw upon new economic theories to consider the social, ideological, and political implications of human engagement with abundant quantities of resources and physical objects and consider how individual and household engagements with material culture were conditioned by the quest for abundance. Abundance shows that the human propensity for mass consumption is not just the result of modern production capacities but fulfills a longstanding focus on plenitude as both the assurance of well-being and a buffer against uncertainty. This book will be of great interest to scholars and students in economics, anthropology, and cultural studies.
