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.

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.
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.
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?
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.
Nothing fills us with a sense of wonder like fossils. What looks at first like a simple rock is in fact a clue that reveals the staggering diversity of ancient environments, the winding pathways of evolution, and the majesty of a vanished earth. But as much as one might daydream of digging a hole in the backyard and finding a Tyrannosaurus, only a few places contain these buried treasures, and when a scientist comes across a remnant of prehistoric life, great care must be taken. What do budding paleontologists need to know before starting their search? In Fantastic Fossils, Donald R. Prothero offers an accessible, entertaining, and richly illustrated guide to the paleontologist's journey. He details the best places to look for fossils, the art of how to find them, and how to classify the major types. Prothero provides expert wisdom about typical fossils that an average person can hope to collect and how to hunt fossils responsibly and ethically. He also explores the lessons that both common and rarer discoveries offer about paleontology and its history, as well as what fossils can tell us about past climates and present climate change. Captivating illustrations by the paleoartist Mary Persis Williams bring to life hundreds of important specimens. Offering valuable lessons for armchair enthusiasts and paleontology students alike, Fantastic Fossils is an essential companion for all readers who have ever dreamed of going in search of traces of a lost world.

The ancient Greeks called it Gaia; the Romans Terra. We know it simply as Earth, the planet we call home. And what a planet it is. Formed around 4.6 billion years ago from the debris of the big bang and long-dead stars, at first it was nothing special, but somehow it evolved to become the most amazing place in the known Universe. The only living planet we know of, it also has a very unusual moon, a remarkably dynamic surface, a complex atmosphere and a deeply mysterious interior. This is Planet Earth is dedicated to the wonders of Planet Earth. Its past is long and dramatic and its future shrouded in mystery. Yet despite centuries of research, only now are we starting to understand Earth's complexity. ABOUT THE SERIES New Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.
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.
For many years, planetary science has been taught as part of the astronomy curriculum, from a very physics-based perspective, and from the framework of a tour of the Solar System - body by body. Over the past decades, however, spacecraft exploration and related laboratory research on extraterrestrial materials have given us a new understanding of planets and how they are shaped by geological processes. Based on a course taught at the University of Tennessee, Knoxville, this is the first textbook to focus on geologic processes, adopting a comparative approach that demonstrates the similarities and differences between planets, and the reasons for these. Profusely illustrated, and with a wealth of pedagogical features, this book provides an ideal capstone course for geoscience majors - bringing together aspects of mineralogy, petrology, geochemistry, volcanology, sedimentology, geomorphology, tectonics, geophysics and remote sensing.
Time-series analysis is used to identify and quantify periodic features in datasets and has many applications across the geosciences, from analysing weather data, to solid-Earth geophysical modelling. This intuitive introduction provides a practical 'how-to' guide to basic Fourier theory, with a particular focus on Earth system applications. The book starts with a discussion of statistical correlation, before introducing Fourier series and building to the fast Fourier transform (FFT) and related periodogram techniques. The theory is illustrated with numerous worked examples using R datasets, from Milankovitch orbital-forcing cycles to tidal harmonics and exoplanet orbital periods. These examples highlight the key concepts and encourage readers to investigate more advanced time-series techniques. The book concludes with a consideration of statistical effect size and significance. This useful book is ideal for graduate students and researchers in the Earth system sciences who are looking for an accessible introduction to time-series analysis.

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.
Vertebrate palaeontology is a lively field, with new discoveries reported every week and not only dinosaurs! This new edition reflects the international scope of vertebrate palaeontology, with a special focus on exciting new finds from China. A key aim is to explain the science. Gone are the days of guesswork. Young researchers use impressive new numerical and imaging methods to explore the tree of life, macroevolution, global change, and functional morphology. The fourth edition is completely revised. The cladistic framework is strengthened, and new functional and developmental spreads are added. Study aids include: key questions, research to be done, and recommendations of further reading and web sites. The book is designed for palaeontology courses in biology and geology departments. It is also aimed at enthusiasts who want to experience the flavour of how the research is done. The book is strongly phylogenetic, and this makes it a source of current data on vertebrate evolution.
