Tunguska, or the End of Nature: A Philosophical Dialogue
by Michael HampeOn June 30, 1908, a mysterious explosion erupted in the skies over a vast woodland area of Siberia. Known as the Tunguska Event, it has been a source of wild conjecture over the past century, attributed to causes ranging from meteors to a small black hole to antimatter. In this imaginative book, Michael Hampe sets four fictional men based on real-life scholars--a physicist (Günter Hasinger and Steven Weinberg), a philosopher (Paul Feyerabend), a biologist (Adolf Portmann), and a mathematician (Alfred North Whitehead)--adrift on the open ocean, in a dense fog, to discuss what they think happened. The result is a playful and highly illuminating exploration of the definition of nature, mankind’s role within it, and what its end might be. Tunguska, Or the End of Nature uses its four-man setup to tackle some of today’s burning issues--such as climate change, environmental destruction, and resource management--from a diverse range of perspectives. With a kind of foreboding, it asks what the world was like, and will be like, without us, whether we are negligible and the universe random, whether nature can truly be explained, whether it is good or evil, or whether nature is simply a thought we think. This is a profoundly unique work, a thrillingly interdisciplinary piece of scholarly literature that probes the mysteries of nature and humans alike.

By proposing different ways to model turbulence effects under these complex conditions, the book will be of considerable interest not only to academic researchers, but also to specialists and junior researchers in the domain of propulsion and power, as well as those whose work involves various applications related to atmospheric, oceanic and planetary physics.
Turkey's Water Policy: National Frameworks and International Cooperation
by Annika Kramer Waltina Scheumann Aysegul KibarogluWater is a strategic natural resource of vital importance to all nations. As such it has been the cause of several international disputes. For Turkey especially, water is crucial to social and economic development. Turkey's current national water regime that emphasises water resources development and management for productive uses, however, faces growing environmental concerns and international criticism regarding transboundary water cooperation. Furthermore, EU accession requires Turkey to adopt an extensive and ambitious body of EU water law. To understand Turkey's position to international water law, the national policies and socio-economic circumstances that impact water resources management need to be considered. This book fills the existing knowledge gap through a broad perspective and analysis of the current state of Turkey's water policy and its management of both national and transboundary waters. It is a unique undertaking that brings together Turkish and international authors, practitioners and academics, covering all aspects of water management

Turning the Tide on Plastic: How Humanity (And You) Can Make Our Globe Clean Again
by Lucy SiegleEnough plastic is thrown away every year to circle the world 4 times More than 8 million tonnes of plastic enter the oceans each year 300 million tonnes of new plastic is produced every year An estimated 15-51 trillion pieces of plastic now litter the world's oceans 38.5 million plastic bottles are used every day in the UK A million plastic bottles are used per minute around the world 500 million plastic straws are used per year Without big action, at the current rate, pieces of plastic will outnumber fish in the ocean by 2050. That is the legacy we are leaving our children and grandchildren. Plastic flows into our lives from every direction and most of it is not recycled. Instead it is incinerated or ends up in landfill, where it will sit for hundreds of years, or enters the world's seas where it fragments into tiny pieces to become microplastics - the environmental scourge of our times. Many of us had assumed that governments, brands and waste authorities were dealing with plastic on our behalf. But the impact of shows such as Blue Planet along with national beach cleans and high-profile campaigns have resulted in a collective wake-up call. If there were plans and strategies, they have not worked as we imagined. It would be easy to feel despondent but instead we need to turn our anger and emotion into action, starting by making a big dent in our own enormous consumption. Turning the tide on Plastic is here just in time. Journalist, broadcaster and eco lifestyle expert Lucy Siegle provides a powerful call to arms to end the plastic pandemic along with the tools we need to make decisive change. It is a clear-eyed, authoritative and accessible guide to help us to take decisive and effective personal action. Because this matters. When it comes to single-use plastics, we are habitual users, reaching out for plastic water bottles, disposable coffee cups, plastic straws and carrier bags multiple times a day. If only 12 of us adopt Lucy's 'reduce, rethink, refill, refuse' approach, we could potentially ditch 3K-15K single items of plastic in a year. When we consider our power as influencers - whether at school, the hairdressers, at work or on the bus - we suddenly become part of something significant. So now is the time to speak up, take action and demand the change you want to see in the ocean, in the supermarket aisles and on the streets. It's time to turn the tide on plastic, and this book will show you how.

Turning to Stone: Discovering the Subtle Wisdom of Rocks
by Marcia BjornerudEarth is vibrantly alive and full of wisdom for those who learn to listen.Earth has been reinventing itself for more than four billion years, keeping a record of its experiments in the form of rocks. Yet most of us live our lives on the planet with no idea of its extraordinary history, unable to interpret the language of the rocks that surround us. Geologist Marcia Bjornerud believes that our lives can be enriched by understanding our heritage on this old and creative planet. Contrary to their reputation, rocks have eventful lives–and they intersect with our own in surprising ways. In Turning to Stone, Bjornerud reveals how rocks are the hidden infrastructure that keep the planet functioning, from sandstone aquifers purifying the water we drink to basalt formations slowly regulating global climate. Bjornerud’s life as a geologist has coincided with an extraordinary period of discovery in the geosciences. From an insular girlhood in rural Wisconsin, she found her way to an unlikely career studying mountains in remote parts of the world and witnessed the emergence of a new understanding of the Earth as an animate system of rock, air, water and life. We are all, most fundamentally, Earthlings and we can find existential meaning and enduring wisdom in stone.

A Tutorial on the WKB Approximation for Innovative Dirac Materials: Graphene and Beyond (Springer Tracts in Modern Physics #292)
by Andrii IurovThis textbook serves to supplement existing quantum mechanics courses with the WKB (Wentzel–Kramers–Brillouin) theory for recently discovered Dirac materials, such as graphene, a dice lattice, and alpha-T3 materials. This includes finding the semiclassical wave function, coordinate-dependent momentum, semiclassical action, the complete set of transport equations, and applicability conditions for the approximation. The discovery of graphene and its unique electronic behavior has transformed research in condensed matter physics over the last 10-15 years, but core curriculum in standard graduate-level physics courses still does not reflect these new developments and this book intends to close this gap. With a clear focus on various types of Dirac Hamiltonians, the multidimensional theory is only a small part of the book. The derivation of the WKB equations for novel Dirac materials and their applications to electron tunneling, turning points and classically forbidden regions, resonances and localized states, and many other crucial physical problems are methodically presented. This textbook aims to expand the existing approach to presenting the WKB approximation and covers recent developments in its applications. This book also includes many informative graphics, as well as problems and exercises with hints at the end of each chapter. Additional detailed mathematical derivations, as well as code in Mathematica, are added throughout the whole book. Ideal for graduate students and researchers in condensed matter physics, this textbook serves as a modern guide for learning the WKB theory.
Tuzo: The Unlikely Revolutionary of Plate Tectonics
by Nick EylesTuzo is the never-before-told story of one of Canada’s most influential scientists and the discovery of plate tectonics, a pivotal development that forever altered how we think of our planet. In 1961, a Canadian geologist named John "Jock" Tuzo Wilson (1908–1993) jettisoned decades of strongly held opposition to theories of moving continents and embraced the idea that they drift across the surface of the Earth. Tuzo tells the fascinating life story of Tuzo Wilson, from his early forays as a teenaged geological assistant working on the remote Canadian Shield in the 1920s to his experiences as a civilian-soldier in the Second World War to his ultimate role as the venerated father of plate tectonics. Illuminating how science is done, this book blends Tuzo’s life story with the development of the theory of plate tectonics, showing along the way how scientific theories are debated, rejected, and accepted. Gorgeously illustrated, Tuzo will appeal to anyone interested in the natural world around them.
Twelve by Twelve: A One-Room Cabin Off the Grid and Beyond the American Dream
by Bill PowersWhy would a successful American physician choose to live in a twelve-foot-by-twelve-foot cabin without running water or electricity? To find out, writer and activist William Powers visited Dr. Jackie Benton in rural North Carolina. No Name Creek gurgled through Benton’s permaculture farm, and she stroked honeybees’ wings as she shared her wildcrafter philosophy of living on a planet in crisis. Powers, just back from a decade of international aid work, then accepted Benton’s offer to stay at the cabin for a season while she traveled. There, he befriended her eclectic neighbors — organic farmers, biofuel brewers, eco-developers — and discovered a sustainable but imperiled way of life. In these pages, Powers not only explores this small patch of community but draws on his international experiences with other pockets of resistance. This engrossing tale of Powers’s struggle for a meaningful life with a smaller footprint proposes a paradigm shift to an elusive “Soft World” with clues to personal happiness and global healing.
Twelve Trees: The Deep Roots of Our Future
by Daniel LewisA compelling global exploration of nature and survival as seen via a dozen species of trees, offering &“extensive insight into the ways in which humans and trees are interconnected&” (BookPage), revealing the challenges facing our planet and how scientists are working urgently to save our forests and our future.The world today is undergoing the most rapid environmental transformation in human history—from climate change to deforestation. Scientists, ethnobotanists, indigenous peoples, and collectives of all kinds are closely studying trees and their biology to understand how and why trees function individually and collectively in the ways they do. In Twelve Trees, Daniel Lewis, curator and historian at one of the world&’s most renowned research libraries, travels the world to learn about these trees in their habitats. Lewis takes us on a sweeping journey to plant breeding labs, botanical gardens, research facilities, deep inside museum collections, to the tops of tall trees, underwater, and around the Earth, journeying into the deserts of the American west and the deep jungles of Peru, to offer a globe-spanning perspective on the crucial impact trees have on our entire planet. When a once-common tree goes extinct in the wild but survives in a botanical garden, what happens next? How can scientists reconstruct lost genomes and habitats? How does a tree store thousands of gallons of water, or offer up perfectly preserved insects from millions of years ago, or root itself in muddy swamps and remain standing? How does a 5,000-year-old tree manage to live, and what can we learn from it? And how can science account for the survival of one species at the expense of others? Twelve Trees &“brims with wonder, appreciation, and even some small hope&” (Booklist) and is an awe-inspiring story of our world, its past, and its future. Note—species include: * The Lost Tree of Easter Island (Sophora toromiro) * The coast redwood (Sequoia sempervirens) * Hymenaea protera [a fossil tree] * The Longleaf pine (Pinus palustris) * East Indian sandalwood (Santanum album) * The Bristlecone pine (Pinus longaeva) * West African ebony (Diospyros crassiflora) * The Tasmanian blue gum eucalyptus (Eucalyptus globulus) * Olive tree (Olea europaea) * Baobab (Adansonia digitata) * the kapok tree (Ceiba pentandra) * The bald cypress (Taxodium distichum)
