Book Description
The theory of plate tectonics transformed earth science. The hypothesis that the earth’s outermost layers consist of mostly rigid plates that move over an inner surface helped describe the growth of new seafloor, confirm continental drift, and explain why earthquakes and volcanoes occur in some places and not others. Lynn R. Sykes played a key role in the birth of plate tectonics, conducting revelatory research on earthquakes. In this book, he gives an invaluable insider’s perspective on the theory’s development and its implications. Sykes combines lucid explanation of how plate tectonics revolutionized geology with unparalleled personal reflections. He entered the field when it was on the cusp of radical discoveries. Studying the distribution and mechanisms of earthquakes, Sykes pioneered the identification of seismic gaps—regions that have not ruptured in great earthquakes for a long time—and methods to estimate the possibility of quake recurrence. He recounts the various phases of his career, including his antinuclear activism, and the stories of colleagues around the world who took part in changing the paradigm. Sykes delves into the controversies over earthquake prediction and their importance, especially in the wake of the giant 2011 Japanese earthquake and the accompanying Fukushima disaster. He highlights geology’s lessons for nuclear safety, explaining why historic earthquake patterns are crucial to understanding the risks to power plants. Plate Tectonics and Great Earthquakes is the story of a scientist witnessing a revolution and playing an essential role in making it.

Book Description
This innovative history of the Okefenokee Swamp reveals it as a place where harsh realities clashed with optimism, shaping the borderland culture of southern Georgia and northern Florida for over two hundred years. From the formation of the Georgia colony in 1732 to the end of the Great Depression, the Okefenokee Swamp was a site of conflict between divergent local communities. Coining the term “ecolocalism” to describe how local cultures form out of ecosystems and in relation to other communities, Megan Kate Nelson offers a new view of the Okefenokee, its inhabitants, and its rich and telling record of thwarted ambitions, unintended consequences, and unresolved questions. The Okefenokee is simultaneously terrestrial and aquatic, beautiful and terrifying, fertile and barren. This peculiar ecology created discord as human groups attempted to overlay firm lines of race, gender, and class on an area of inherent ambiguity and blurred margins. Rice planters, slaves, fugitive slaves, Seminoles, surveyors, timber barons, Swampers, and scientists came to the swamp with dreams of wealth, freedom, and status that conflicted in varied and complex ways. Ecolocalism emerged out of these conflicts between communities within the Okefenokee and other borderland swamps. Nelson narrates the fluctuations, disconnections, and confrontations embedded in the muck of the swamp and the mire of its disorderly history, and she reminds us that it is out of such places of intermingling and uncertainty that cultures are forged.

Book Description
Physical Geology is a vast subject and it is not possible to cover all aspects in one book. This book does not invent the wheel but merely put together sets of updated but concise material on Physical Geology with lots of illustrations. All illustrations are created by hand and give a real classroom feel to the book. Students or readers can easily reproduce them by hand. This is a book, where a diagram says it all. The book is divided into four parts. The first part “The Solar System and Cosmic Bodies” deals with elements of our Solar System and the cosmic bodies around it (like meteorites, asteroids, etc.). The second part “The Earth Materials” deals with Earth and its internal structure. The third part “The Hydrologic System” is more exhaustive and deals with the hydrological system of the Earth including Weathering and Mass Wasting, Streams, Groundwater, Karst, Glaciers, Oceans and Aeolian Processes and Landforms. The fourth and the final part “The Tectonic System” deals with different aspects of Plate Tectonics, Earthquakes and Volcanoes.

Book Description
From December 1811 to February 1812, massive earthquakes shook the middle Mississippi Valley, collapsing homes, snapping large trees midtrunk, and briefly but dramatically reversing the flow of the continent’s mightiest river. For decades, people puzzled over the causes of the quakes, but by the time the nation began to recover from the Civil War, the New Madrid earthquakes had been essentially forgotten. In The Lost History of the New Madrid Earthquakes, Conevery Bolton Valencius remembers this major environmental disaster, demonstrating how events that have been long forgotten, even denied and ridiculed as tall tales, were in fact enormously important at the time of their occurrence, and continue to affect us today. Valencius weaves together scientific and historical evidence to demonstrate the vast role the New Madrid earthquakes played in the United States in the early nineteenth century, shaping the settlement patterns of early western Cherokees and other Indians, heightening the credibility of Tecumseh and Tenskwatawa for their Indian League in the War of 1812, giving force to frontier religious revival, and spreading scientific inquiry. Moving into the present, Valencius explores the intertwined reasons—environmental, scientific, social, and economic—why something as consequential as major earthquakes can be lost from public knowledge, offering a cautionary tale in a world struggling to respond to global climate change amid widespread willful denial. Engagingly written and ambitiously researched—both in the scientific literature and the writings of the time—The Lost History of the New Madrid Earthquakes will be an important resource in environmental history, geology, and seismology, as well as history of science and medicine and early American and Native American history.

Book Description
In the past decades, work has changed dramatically. Yet we are still sent into the new world of work with old, outdated tools, expectations, and strategies. This leaves us ill-equipped in our pursuit of meaningful work that will impact our communities and change the world. The result? Unmet expectations and unfulfilled longings. Not to mention curiosity about how to do the work we sense God calling us to. Make Work Matter provides a blueprint for a better future. Filled with stories and insights from faithful entrepreneurs and built on solid research, this book will help you - discover what God is calling you to do in a changing world - define where you are in this season of work - embrace what the Bible says (and doesn't say) about calling - develop a mindset and habits suited for the new world of work - reflect on and work out ways that sustain you on the journey It's time to close the gap between what you're doing now and the meaningful work you desire to accomplish. This book will help you chart your own way forward.
