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.

From the origin of life, through the age of dinosaurs stalked by the terrifying Tyrannosaurus rex, to the earliest humans, this book tells the story of life on Earth. Dinosaurs may be the stars of the show, but the book is truly comprehensive, with fossil plants, invertebrates, amphibians, fish, birds, reptiles, mammals, and even early bacteria conjuring up an entire past world. To put all of these extinct species in context, the book explores geological time and the way life-forms are classified. It also looks at how fossils preserve the story of evolution, and how it can be deciphered. The chapter on "Young Earth" explains how forces shaped Earth and steered the course of life. The main part of the book - "Life on Earth" - lays out and catalogues the rich story of life, from its beginnings 4 billion years ago, through each geological period, such as the Jurassic and Cretaceous, to the present. Combining stunning visuals and authoritative text, Dinosaurs and Prehistoric Life is a fascinating and revealing encyclopedia that will appeal to the whole family.

* Shall we take an umbrella... or evacuate the city? The Weather Machine is about a miraculous-but-overlooked invention that helps us through our daily lives - and sometimes saves them - by allowing us to see into the future. When Superstorm Sandy hit North America, weather scientists had predicted its arrival a full eight days beforehand, saving countless lives and astonishing us with their capability. Their skill is unprecedented in human history and draws on nearly every major invention of the last two centuries: Newtonian physics, telecommunications, spaceflight and super-computing. In this gripping investigation, Andrew Blum takes us on a global journey to explain this awe-inspiring feat - from satellites circling the Earth, to weather stations far out in the ocean, through some of the most ingenious minds and advanced algorithms at work today. Our destination: the simulated models they have constructed of our planet, which spin faster than time, turning chaos into prediction, offering glimpses of our future with eery precision. This collaborative invention spans the Earth and relies on continuous co-operation between all nations - a triumph of human ingenuity and diplomacy we too often shrug off as a tool for choosing the right footwear each morning. But in this new era of extreme weather, we may come to rely on its maintenance and survival for our own.
'Vivid, thrilling, a delight ... Tim Flannery is a palaeontologist and ecologist of global standing, and this is a compelling and authoritative narrative of the evolution of Europe's flora and fauna, from the formation of the continent to its near future ... an exciting book, full of wonder' James McConnachie, Sunday Times A place of exceptional diversity, rapid change, and high energy, Europe has literally been at the crossroads of the world ever since the interaction of Asia, North America and Africa formed the tropical island archipelago that would become the continent of today. In this unprecedented evolutionary history, Tim Flannery shows how for the past 100 million years Europe has absorbed wave after wave of immigrant species; taking them in, transforming them, and sometimes hybridising them. Flannery reveals how, in addition to playing a vital role in the evolution of our own species, Europe was once the site of the formation of the first coral reefs, the home of some of the world's largest elephants, and now has more wolves than North America. This groundbreaking book charts the history of the land itself and the forces shaping life on it - including modern humans - to create a portrait of a continent that continues to exert a huge influence on the world today.

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.
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. In this remarkable new book, the Smithsonian's star 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.

Changes in climate and sea level are nothing new - over the last 700 million years, the Earth has been slowly but constantly changing from within. We now know that our planet's surface, far from being fixed or stable, is composed of tectonic plates in continual movement, drifting in oceans which themselves appear and disappear over millennia. Such insecurity lies at the heart of both the physical and the living world, providing the creative impetus for all life forms to confront change, adapt and evolve.
This exceptional book celebrates the inevitability of global change and highlights our need as human beings to recognize and adjust to it. Its entertaining and accessible text displays a remarkable breadth and diversity of knowledge, drawing upon discoveries in natural history, geology, geography and paleontology to unravel secrets of millions of years. Its unique structure offers the opportunity to pursue two distinct but parallel narratives in one volume - the first characterized by discrete photo-essay spreads, and the second by authoritative running text illustrated with clearly numbered icons. Designed either to be browsed through like a website or read in chronological sequence, each chapter provides a fascinating glimpse into the formation and development of our world.
Glorious panoramic photography by the author, a specialist in interpretive landscape, reveals the physical legacy of the Earth's distant past. This intriguing exploration of key sites, often remote and inaccessible, provides a clear and original perspective on the Earth as a dynamic, interactive planet. The compelling narrative by a bestselling science writer places the history of our planet in a challenging contemporary context in which human beings, like all living things, must embrace change or fail to survive.
As a science writer Ron Redfern has received a number of prestigious literary and academic awards, perhaps most notably the American Institute of Professional Geologists' Outstanding Achievement Award. This was presented to him before his permanent return to England in 1996. The award was in recognition of his contribution to the public understanding in science.

Trilobite! is an unashamedly trilobito-centric view of the world unravelling the history of the exotic, crustacean-like animals which dominated the seas for three hundred million years. These arthropods witnessed continents move, mountain chains elevated and eroded; they survived ice ages and volcanic eruptions, evolving and adapting exquisitely to their environment. They watched through their crystal eyes whilst life evolved. Their own evolution calibrated geological time itself.
Structured like a detective story, this is a light, but highly informative account of the wonders of scientific discovery.
