The Second Great Dune Trilogy contains God Emperor of Dune, Heretics of Dune and Chapter House Dune, and concludes the Dune Chronicles, one of the most influential SF series ever written. Herbert's evocative, epic tales are set on the desert planet Arrakis, the focus for a complex political and military struggle with galaxy-wide repercussions. More than three thousand years have passed since the first events recorded in Dune. Only one link survives with those tumultuous times: the grotesque figure of Leto Atreides, son of the prophet Paul Muad'Dib, and now the virtually immortal God Emperor of Dune. He alone understands the future, and he knows with a terrible certainty that the evolution of his race is at an end unless he can breed new qualities into his species. But to achieve his final victory, Leto Atreides must also bring about his own downfall... Read the series which inspired the 2021 Denis Villeneuve epic film adaptation, Dune, starring Oscar Isaac, Timothée Chalamet, Zendaya and Josh Brolin.

How living in space will affect future generations—and what the potential unintended consequences of space settlements are. We are on the cusp of a golden age of space travel in which, for the first time, it will be possible for large numbers of people to venture into space. Some intend to stay. But what happens—and will happen—to us in the extreme conditions of space? What should space tourists expect to happen to them during a journey to an orbiting space station, the Moon, or Mars? What would happen to children born on another planet? Would they evolve into a new species? In Becoming Martian, Scott Solomon explores the many ways in which humanity’s migration into space will change our bodies and our minds. This book focuses on the latest science, taking readers to the front lines of research. We hear from astronauts, including Scott Kelly who writes the foreword, and we join a team of scientists guiding a rover across the surface of Mars. We visit a high-security lab where engineers are simulating space radiation to measure its effects on the body. We travel to isolated islands where field biologists are gleaning insights into evolutionary processes applicable to people isolated on faraway planets. We meet synthetic biologists developing gene-editing tools to equip future humans to thrive in alien environments. We watch a rocket designed to carry humanity to Mars make its first successful launch. And then we ask, knowing what we know: Should we go?

Russia is the largest country on the planet, a multi-ethnic empire, a great power of global significance. For much of its history it has been a 'peasant state', in which peasant society and values interacted critically with those of the ruling elites. In modern times its society has produced artists, writers, musicians, scientists and cosmonauts who have made a unique contribution to world culture. In the twentieth century, Russia has been the scene of the world's greatest social experiment - the most powerful challenge ever mounted to hegemonic Western values. Roger Bartlett traces the history of the country from its beginnings in Kiev Russia, through the Muscovite and Imperial, Soviet and post-Soviet periods, to the start of the twenty-first century. While offering a broad perspective on Russia's historical development, Bartlett focuses on the origins of Russian political culture and the place of the majority peasant population in the Russian/Soviet polity. Lucid, balanced and authoritative, it is the ideal introduction for all those with an interest in Russia's past, and its significance for the country's present.

Our escalating consumption of natural products and services directly impacts the planet. The challenge is to ensure that our needs are not exceeding the ecological capacity of the biosphere. But how to know if they do so? To answer this question and assess the human impact on nature, Wackernagel and Rees have developed Ecological Footprint that can measure how much natural capital we use to sustain our lifestyles and how much capital nature can provide us. On the other hand, to be able to present in a single measure for each economy and to focus strictly on the environmental issues, World Economic Forum (WEF) developed Environmental Sustainability Index (ESI). The ESI creates a series of comparative benchmarks of environmental decision-making onto a more fact - based and analytical function. This book analyzes the current situation of sustainable development indicators and discusses the concepts of the EF and the ESI and explores the application of the EF and ESI to the regional level by Case Study: Sustainability of Shandong. EF and ESI is an essential addition to the study and management of reginal to be sustainable.

Focus your telescope and get ready to learn all about the night sky. Eyewitness Explorer: Night Sky Detective is full of activities for adventurous hands-on learning with activities to help spot different constellations, make paper planets, study Jupiter and its moons, create a star chart, escape velocity, and even launch a homemade rocket. Eyewitness Explorers encourage hands-on learning with 30 easy activities that help children observe, explore, and learn about the natural world. Each book explains the science behind the activities, laying the essential groundwork for contextualizing the experience to come. But at the heart of the books are the activities themselves — a chance to learn by doing with experiments that can be carried out right at home. Most can even be completed with materials already on hand, so there's no complicated preparation or specialized equipment needed. Simply choose one of the projects and follow the step-by-step, photographically illustrated instructions to create rainbows, make a moth trap, grow stalactites, mix mineral paint, and much more.

In view of the global crisis triggered by climate change and other ecological problems of the Anthropocene, there is growing concern that the age of humans on Earth could be coming to an end. The question of the future of the human species on the planet and its scope for action has been a source of debate in literature for a long time. This volume shows that literature helps us to understand the future not simply as a time to come, but as a realm of potential and change. It reflects on how literature casts new perspectives on traditional concepts and relationships such as human/environment, nature/culture or past/future. The contributions collected in this volume bring together German and Italian perspectives and draw from different disciplines (e.g., literary criticism, philosophy, psychoanalysis). They examine different cultural contexts (in Europe, America, and Africa) and focus on periods of literary history, ranging from Romanticism to the 21st century. They all outline an idea of how we can imagine the future beyond the extremes of a blind belief in progress on the one hand and the fear of catastrophe on the other.
