Wat Moet Ons Met Ons Kerk Doen? is 'n poging om te probeer verstaan waar ons as Afrikaners teologies vandaan kom, watter kragte en magte ons en ons Kerk gevorm het en hoe ons Kerk tans daar uitsien.
Die N.G.Kerk was 'n belangrike en rigtinggewende rolspele in die opheffing van die Afrikaner na die Britse vergrype tydens en na die Tweede Vryheidsoorlog. Tans word die N.G.Kerk ervaar as 'n instansie wat ongevoelig teenoor die geestelike behoeftes van haar lidmate staan.

Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to only enter our awareness when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past. Palaeontologist Nick Pyenson takes us to the ends of the earth and to the cutting edge of whale research as he searches for the answers to some of our biggest questions about these graceful giants. His rich storytelling takes us deep inside the Smithsonian's unparalleled fossil collection, to frigid Antarctic waters, and to the arid desert of Chile, where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is an illuminating story of scientific discovery that brings readers closer to the most enigmatic and beloved animals of all time.
If you only have 30 seconds, there is time - using this book - to make sense of the science behind the seeming vagaries of the weather, the controversies, predictions and forecasts for climate change that shape our day-to-day experiences of the great outdoors. Ever since Aristotle first tried to explain the forces that seem to fall from the heavens, meteorology has opened up the study of weather, and caused disputes over the reasons why seasons change, where precipitation falls, why winds blow and when the sun shines. From halcyon days to hurricanes, supercells to silver linings, global warming to giant hailstones, here is the ultimate guide to a near-universal preoccupation: what's the weather like?
This hands-on introduction to numerical geodynamic modelling provides a solid grounding in the necessary mathematical theory and techniques, including continuum mechanics and partial differential equations, before introducing key numerical modelling methods and applications. Fully updated, this second edition includes four completely new chapters covering the most recent advances in modelling inertial processes, seismic cycles and fluid-solid interactions, and the development of adaptive mesh refinement algorithms. Many well-documented, state-of-the-art visco-elasto-plastic 2D models are presented, which allow robust modelling of key geodynamic processes. Requiring only minimal prerequisite mathematical training, and featuring over sixty practical exercises and ninety MATLAB (R) examples, this user-friendly resource encourages experimentation with geodynamic models. It is an ideal introduction for advanced courses and can be used as a self-study aid for graduates seeking to master geodynamic modelling for their own research projects.
Geography is getting stranger. Out there, fleets of new islands are under construction and micro-nations are struggling into the light. As new borders and boundaries ebb and flow with increasing speed, it feels as if our old maps are being discarded, redrawn or torn up. Alastair Bonnett uncovers the stories of thirty-nine extraordinary places, each of which challenges us to re-imagine the world around us. From emerging islands, disruptive enclaves and bold utopian visions to uncanny ruins, ghostly tunnels and hidden landscapes - these are destinations that lie beyond ordinary coordinates. A follow on from the critically acclaimed Off the Map, this is a timely and fascinating discussion of place, ownership and ideas of state.
Almost Human is the personal story of a charismatic and visionary palaeontologist, a rich and readable narrative about science, exploration, and what it means to be human.
In 2013, Wits University reasearch professor Lee Berger caught wind of a cache of bones in a hard-to-reach underground cave near Johannesburg. He put out a call around the world for collaborators – men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of ‘underground astronauts’, Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known pre-hominids with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species: Homo naledi.
The cave proved to be the richest pre-hominid site ever discovered, full of implications that challenge how we define ourselves as human. Did these ancestors of ours bury their dead? If so, they must have had an awareness of death, a level of self-knowledge: the very characteristic we used to define ourselves as human. Did an equally advanced species inhabit Earth with us, or before us?
Addressing these questions, Berger counters the arguments of those colleagues who have questioned his controversial interpretations and astounding finds.

'Rich and strange from the tip of its title to its deep-sunk bones' Robert Macfarlane From the author of Leviathan, or, The Whale, comes a composite portrait of the subtle, beautiful, inspired and demented ways in which we have come to terms with our watery planet. In the third of his watery books, the author goes in pursuit of human and animal stories of the sea. Of people enchanted or driven to despair by the water, accompanied by whales and birds and seals - familiar spirits swimming and flying with the author on his meandering odyssey from suburbia into the unknown. Along the way, he encounters drowned poets and eccentric artists, modernist writers and era-defining performers, wild utopians and national heroes - famous or infamous, they are all surprisingly, and sometimes fatally, linked to the sea. Out of the storm-clouds of the twenty-first century and our restive time, these stories reach back into the past and forward into the future. This is a shape-shifting world that has never been certain, caught between the natural and unnatural, where the state between human and animal is blurred. Time, space, gender and species become as fluid as the sea. Here humans challenge their landbound lives through art or words or performance or myth, through the animal and the elemental. And here they are forever drawn back to the water, forever lost and found on the infinite sea.
Weather and climate are not the same. Weather is what occurs outdoors on a daily basis and is unpredictable from one week to the next, whereas climate follows a stable pattern that is developed over centuries. The planet is divided into climate zones-tropical, temperate and polar-based on temperature differences with distance from the equator where the sun is most intense and temperature affects humidity, precipitation, cloudiness and wind. To understand what drives our climate, scientists study the atmosphere, the oceans, biosphere, hydrosphere, and lithosphere. 30-Second Climate is an immediately accessible guide to the 50 key factors affecting Earth's climate, past, present and future, each explained in half a minute. From atmospheric circulation to zero carbon, this is the quickest way to know your planet.

Hailed as "the great nature writer of this generation" (Wall Street Journal), Robert Macfarlane is the celebrated author of books about the intersections of the human and the natural realms. In Underland, he delivers his masterpiece: an epic exploration of the Earth's underworlds as they exist in myth, literature, memory, and the land itself. In this highly anticipated sequel to his international bestseller The Old Ways, Macfarlane takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind. Traveling through "deep time"-the dizzying expanses of geologic time that stretch away from the present-he moves from the birth of the universe to a post-human future, from the prehistoric art of Norwegian sea caves to the blue depths of the Greenland ice cap, from Bronze Age funeral chambers to the catacomb labyrinth below Paris, and from the underground fungal networks through which trees communicate to a deep-sunk "hiding place" where nuclear waste will be stored for 100,000 years to come. "Woven through Macfarlane's own travels are the unforgettable stories of descents into the underland made across history by explorers, artists, cavers, divers, mourners, dreamers, and murderers, all of whom have been drawn for different reasons to seek what Cormac McCarthy calls "the awful darkness within the world." Global in its geography and written with great lyricism and power, Underland speaks powerfully to our present moment. Taking a deep-time view of our planet, Macfarlane here asks a vital and unsettling question: "Are we being good ancestors to the future Earth?" Underland marks a new turn in Macfarlane's long-term mapping of the relations of landscape and the human heart. From its remarkable opening pages to its deeply moving conclusion, it is a journey into wonder, loss, fear, and hope. At once ancient and urgent, this is a book that will change the way you see the world.
What can long-dead dinosaurs teach us about our future? Plenty, according to world-renowned paleontologist and recent star of BBC show The Day the Dinosaurs Died Dr Kenneth Lacovara, who has discovered some of the largest creatures to ever walk the Earth, including the super-massive Dreadnoughtus. 'Majestic, awe-inspiring and deeply humbling. Kenneth Lacovara reveals how dinosaurs have changed how we understand time, the world and ourselves' DR ALICE ROBERTS, anatomist and anthropologist, television presenter, author and professor `This is a dinosaur book with a difference. In lyrical prose Kenneth Lacovara shows how an understanding of the past helps to understand the present. The dinosaurs played no role in the great extinction that ended their era: we, on the other hand, are playing a major part in the extinction that is taking place today. And unless we change our ways, if we continue destroying the natural world, this will lead inevitably to our own extinction. But unlike the dinosaurs we have the power to turn things around.' DR JANE GOODALL, DBE, conservationist, founder of the Jane Goodaal Institute and UN Messenger of Peace `Kenneth Lacovara LOVES Dinosaurs, LOVES science and truly LOVES telling you about it. Few non-fiction writers wield words with more poetic and potent affection for their subject. Ken's deep scholarship and clear enjoyment of his subject always makes ME feel smarter. A man obsessed not just with his subject matter, but with showing us how looking into our deep past can illuminate our future.' ADAM SAVAGE of THE DISCOVERY CHANNEL By tapping into the wonder that dinosaurs inspire, Dr Lacovara weaves together the stories of our geological awakening, of humanity's epic struggle to understand the nature of deep time, the meaning of fossils, and our own place on the vast and bountiful tree of life. Go on a journey, back to when dinosaurs ruled the Earth, to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but fascinating questions, such as: Is a penguin a dinosaur? How are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Dr Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging - a reminder that our place on this planet is both precarious and potentially fleeting. As we move into an uncertain environmental future, it has never been more important to understand the past.
In 1816, the climate went berserk. The winter brought extreme cold, and torrential rains unleashed massive flooding in Asia. Western Europe and North America experienced a "year without a summer," while failed harvests in 1817 led to the "year of famine." At the time, nobody knew that all these disturbances were the result of a single event: the eruption of Mount Tambora in what is now Indonesia - the greatest volcanic eruption in recorded history. In this book, leading climate historian Wolfgang Behringer provides the first globally comprehensive account of a climate catastrophe that would cast the world into political and social crises for years to come. Concentrating on the period between 1815 and 1820, Behringer shows how this natural occurrence led to worldwide unrest. Analyzing events as diverse as the persecution of Jews in Germany and Peterloo Massacre in the United Kingdom, witch hunts in South Africa and anti-colonial uprisings in Asia, Behringer demonstrates that no region on earth was untouched by the effects of the eruption. Drawing parallels with our world today, the eruption of Mount Tambora and its aftermath becomes a case study for how societies and individuals respond to climate change, what risks emerge and how they might be overcome. This comprehensive account of the impact of one of the greatest environmental disasters in human history will be of interest to a wide readership and to anyone seeking to understand better how we might mitigate the effects of climate change.

From one of the world's pre-eminent marine biologists comes a dazzling account of the wonders that lie beneath the ocean's surface, and an empowering vision of how we can protect them Fewer people have been to the deepest part of the ocean than have been to the moon. Even now, the vast majority of this wilderness - which covers over 70% of the planet and forms its largest ecosystem - has never been seen by human eyes, let alone explored or investigated by scientists. Yet our oceans contain perhaps 90% of all life, and the physical and biological processes within it are critical to supporting our existence on Earth. Professor Alex Rogers has spent the past 30 years studying life in the deep ocean. In this book, he takes us on an epic and utterly unforgettable voyage to an alien world, and brings us right to the edge of what is known about our oceans today. Introducing us to glittering coral gardens, submarine mountains and a range of bizarre and breathtaking sea creatures, many of which he discovered first-hand, Rogers not only illustrates the ocean's enormous and untold impact on our lives, but also shows how we are damaging it catastrophically through pollution, overfishing, and the insidious and global effects of climate change. Imbued with the author's infectious sense of wonder, and replete with stunning photography of underwater life, The Deep is a magisterial study of a world we are only just beginning to understand - and a profoundly hopeful call to arms for us to reshape our relationship with it, before it is too late.
'Our everyday lives are connected to the deep ocean in ways we seldom realise.' Between these pages is everything you need to know about our oceans, explained in 25 questions. In Ask An Ocean Explorer marine biologist of over 20 years and advisor for the BBC's Blue Planet II, Dr Jon Copley, explains the science and wonder of the deep ocean. Combining untold history of ocean exploration and personal account of what it's like to be a 'bathynaut' diving in a mini-submarine, Ask An Ocean Explorer will bring to light weird and wonderful deep-sea creatures that we find down there and how the oceans and their health is connected to our everyday lives.
"The Southern Ocean is a wild and elusive place, an ocean like no other. With its waters lying between the Antarctic continent and the southern coastlines of Australia, New Zealand, South America, and South Africa, it is the most remote and inaccessible part of the planetary ocean, the only part that flows around Earth unimpeded by any landmass. It is notorious amongst sailors for its tempestuous winds and hazardous fog and ice. Yet it is a difficult ocean to pin down. Its southern boundary, defined by the icy continent of Antarctica, is constantly moving in a seasonal dance of freeze and thaw. To the north, its waters meet and mingle with those of the Atlantic, Indian, and Pacific oceans along a fluid boundary that defies the neat lines of a cartographer." So begins Joy McCann's Wild Sea, the remarkable story of the world's remote Southern, or Antarctic, Ocean. Unlike the Pacific, Atlantic, Indian, and Arctic Oceans with their long maritime histories, little is known about the Southern Ocean. This book takes readers beyond the familiar heroic narratives of polar exploration to explore the nature of this stormy circumpolar ocean and its place in Western and Indigenous histories. Drawing from a vast archive of charts and maps, sea captains' journals, whalers' log books, missionaries' correspondence, voyagers' letters, scientific reports, stories, myths, and her own experiences, McCann embarks on a voyage of discovery across its surfaces and into its depths, revealing its distinctive physical and biological processes as well as the people, species, events, and ideas that have shaped our perceptions of it. The result is both a global story of changing scientific knowledge about oceans and their vulnerability to human actions and a local one, showing how the Southern Ocean has defined and sustained southern environments and people over time. Beautifully and powerfully written, Wild Sea will raise a broader awareness and appreciation of the natural and cultural history of this little-known ocean and its emerging importance as a barometer of planetary climate change.
