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.

WHEN we eat may be as important as WHAT we eat.
Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock.
Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.

"Fascinating and exhilarating-Sean B. Carroll at his very best."-Bill Bryson, author of The Body: A Guide for Occupants From acclaimed writer and biologist Sean B. Carroll, a rollicking, awe-inspiring story of the surprising power of chance in our lives and the world Why is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world. Like every other species, we humans are here by accident. But it is shocking just how many things-any of which might never have occurred-had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death. This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.
Why do the debates about evolution persist, despite the plentiful evidence for it? Breaking down the notion that public resistance to evolution is strictly due to its perceived conflict with religion, this concise book shows that evolution is in fact a counterintuitive idea that is difficult to understand. Kostas Kampourakis, an experienced science educator, takes an insightful, interdisciplinary approach, providing an introduction to evolutionary theory written with clarity and thoughtful reasoning. Topics discussed include evolution in the public sphere, evolution and religion, the conceptual obstacles to understanding evolution, the development of Darwin's theory, the most important evolutionary concepts, as well as evolution and the nature of science. Understanding Evolution presents evolutionary theory with a lucidity and vision that readers will quickly appreciate, and is intended for anyone wanting an accessible and concise guide to evolution.
What does drug withdrawal have in common with a broken heart? Why is the enemy of memory not time, but other memories? How can a blind person learn to see with her tongue or a deaf person learn to hear with his skin? Why did many people in the 1980s mistakenly perceive book pages to be slightly red in colour? Why is the world's best archer armless? Might we someday control a robot with our thoughts, just as we do our fingers and toes? Why do we dream at night, and what does that have to do with the rotation of the planet? The answer to these questions is right behind our eyes. The greatest technology we have ever discovered on this planet is the three-pound organ carried around in the vault of the skull. This book is not simply about what the brain is, but what it does. The magic of the brain is not found in the parts it's made of, but in the way those parts unceasingly re-weave themselves in an electric, living fabric. Surf the leading edge of neuroscience atop the anecdotes and metaphors that have made Eagleman one of the best scientific translators of our generation. Covering decades of research to the present day, Livewired also presents new discoveries from Eagleman's own laboratory, from synaesthesia to dreaming to wearable neurotech devices that revolutionize how we think about the senses.
The increased and widespread availability of large network data resources in recent years has resulted in a growing need for effective methods for their analysis. The challenge is to detect patterns that provide a better understanding of the data. However, this is not a straightforward task because of the size of the data sets and the computer power required for the analysis. The solution is to devise methods for approximately answering the questions posed, and these methods will vary depending on the data sets under scrutiny. This cutting-edge text introduces biological concepts and biotechnologies producing the data, graph and network theory, cluster analysis and machine learning, before discussing the thought processes and creativity involved in the analysis of large-scale biological and medical data sets, using a wide range of real-life examples. Bringing together leading experts, this text provides an ideal introduction to and insight into the interdisciplinary field of network data analysis in biomedicine.
The book is an indispensable companion to all students of biology, but particularly those enrolled in courses concerning experimental design, data analysis, hypothesis testing, research methods, or any practical project work.
Why are we influenced by the behaviour of complete strangers? Why does the brain register similar pleasure when I perceive something as 'fair' or when I eat chocolate? Why can we be so profoundly hurt by bereavement? What are the evolutionary benefits of these traits? The young discipline of 'social cognitive neuroscience' has been exploring this fascinating interface between brain science and human behaviour since the late 1990s. Now one of its founding pioneers, Matthew D. Lieberman, presents the discoveries that he and fellow researchers have made. Using fMRI scanning and a range of other techniques, they have been able to see that the brain responds to social pain and pleasure the same way as physical pain and pleasure; and that unbeknown to ourselves, we are constantly 'mindreading' other people so that we can fit in with them. It is clear that our brains are designed respond to and be influenced by others. For good evolutionary reasons, he argues, we are wired to be social. The implications are numerous and profound. Do we have to rethink what we understand by identity, and free will? How can managers improve the way their teams relate and perform? Could we organize large social institutions in ways that would work far better? And could there be whole new methods of education?
Bringing Back the Beaver is farmer-turned-ecologist Derek Gow's inspirational and often riotously funny firsthand account of how the movement to rewild the British landscape with beavers has become the single most dramatic and subversive nature conservation act of the modern era. Since the early 1990s - in the face of outright opposition from government, landowning elites and even some conservation professionals - Gow has imported, quarantined and assisted the reestablishment of beavers in waterways across England and Scotland. In addition to detailing the ups and downs of rewilding beavers, Bringing Back the Beaver makes a passionate case as to why the return of one of nature's great problem solvers will be critical as part of a sustainable fix for flooding and future drought, whilst ensuring the creation of essential lifescapes that enable the broadest possible spectrum of Britain's wildlife to thrive.
As a scientist, David Linden had devoted his career to understanding the brain processes and behaviors that are common to us all. That is, until a few years ago, when he found himself on OKCupid. Looking through that vast catalog of human difference, he got to thinking, where does it all come from? Why does one person have perfect pitch, a taste for hoppy beer, and an aversion to bathroom selfies? That is, what makes you, you, and me, me? In Unique, David Linden tells a riveting and accessible story of human individuality. Exploring topics that touch all of our lives-among them sexuality, gender identity, food preferences, biological rhythms, mood, personality, memory, and intelligence-Linden shows that human individuality is not simply a matter of nature versus nurture. Rather, it is a product of the complex, and often counterintuitive, interplay between our genetic blueprints and our experiences. Experience isn't just the how your parents reared you, but the diseases you have had, the foods you have eaten, the bacteria that reside in your body, the weather during your early development, and the technology you've been exposed to. Drawing all those factors together, Linden argues that human individuality is key to how we live as individuals and groups and explores how questions of individuality are informing social discussions of morality, public policy, religion, healthcare, education, and law. Like Carl Zimmer's She Has Her Mother's Laugh and Robert Sapolsky's Behave, Unique unveils a new vista on the intricacies of human existence. But, for all its brilliance and insight, this is no weighty academic tome. Told with Linden's unusual combination of authority and openness, seriousness of purpose and a great sense of humor, Unique sets a new standard for what popular science can be.
`Inferior is more than just a book. It's a battle cry - and right now, it's having a galvanising effect on its core fanbase' Observer Are women more nurturing than men? Are men more promiscuous than women? Are males the naturally dominant sex? And can science give us an impartial answer to these questions? Taking us on an eye-opening journey through science, Inferior challenges our preconceptions about men and women, investigating the ferocious gender wars that burn in biology, psychology and anthropology. Angela Saini revisits the landmark experiments that have informed our understanding, lays bare the problem of bias in research, and speaks to the scientists finally exploring the truth about the female sex. The result is an enlightening and deeply empowering account of women's minds, bodies and evolutionary history. Interrogating what these revelations mean for us as individuals and as a society, Inferior unveils a fresh view of science in which women are included, rather than excluded.
A leading expert in animal behavior takes us into the wild to better understand and manage our fears. Fear, honed by millions of years of natural selection, kept our ancestors alive. Whether by slithering away, curling up in a ball, or standing still in the presence of a predator, humans and other animals have evolved complex behaviors in order to survive the hazards the world presents. But, despite our evolutionary endurance, we still have much to learn about how to manage our response to danger. For more than thirty years, Daniel Blumstein has been studying animals' fear responses. His observations lead to a firm conclusion: fear preserves security, but at great cost. A foraging flock of birds expends valuable energy by quickly taking flight when a raptor appears. And though the birds might successfully escape, they leave their food source behind. Giant clams protect their valuable tissue by retracting their mantles and closing their shells when a shadow passes overhead, but then they are unable to photosynthesize, losing the capacity to grow. Among humans, fear is often an understandable and justifiable response to sources of threat, but it can exact a high toll on health and productivity. Delving into the evolutionary origins and ecological contexts of fear across species, The Nature of Fear considers what we can learn from our fellow animals-from successes and failures. By observing how animals leverage alarm to their advantage, we can develop new strategies for facing risks without panic.
J. B. S. Haldane's life was rich and strange, never short on genius or drama-from his boyhood apprenticeship to his scientist father, who first instilled in him a devotion to the scientific method; to his time in the trenches during the First World War, where he wrote his first scientific paper; to his numerous experiments on himself, including inhaling dangerous levels of carbon dioxide and drinking hydrochloric acid; to his clandestine research for the British Admiralty during the Second World War. He is best remembered as a geneticist who revolutionized our understanding of evolution, but his peers hailed him as a polymath. One student called him "the last man who might know all there was to be known." He foresaw in vitro fertilization, peak oil, and the hydrogen fuel cell, and his contributions ranged over physiology, genetics, evolutionary biology, mathematics, and biostatistics. He was also a staunch Communist, which led him to Spain during the Civil War and sparked suspicions that he was spying for the Soviets. He wrote copiously on science and politics in newspapers and magazines, and he gave speeches in town halls and on the radio-all of which made him, in his day, as famous in Britain as Einstein. It is the duty of scientists to think politically, Haldane believed, and he sought not simply to tell his readers what to think but to show them how to think. Beautifully written and richly detailed, Samanth Subramanian's A Dominant Character recounts Haldane's boisterous life and examines the questions he raised about the intersections of genetics and politics-questions that resonate even more urgently today.
Origins of Biodiversity is a unique introduction to the fields of macroevolution and macroecology, which explores the evolution and distribution of biodiversity across time, space and lineages. Using an enquiry-led framework to encourage active learning and critical thinking, each chapter is based around a case-study to explore concepts and research methods from contemporary macroevolution and macroecology. The book focuses on the process of science as much as the biology itself, to help students acquire the research skills and intellectual tools they need to understand and investigate the biological world around them. In particular, the emphasis on hypothesis testing encourages students to develop and test their own ideas. This text builds upon the foundations offered in most general introductory evolutionary biology courses to introduce an exciting range of ideas and research tools for investigating patterns of biodiversity.
Are we alone in the universe, or are there other life forms 'out there'? This is one of the most scientifically and philosophically important questions that humanity can ask. Now, in the early 2020s, we are tantalizingly close to an answer. As this book shows, the answer will almost certainly be that life forms are to be found across the Milky Way and beyond. They will be thinly spread, to be sure. Yet the number of inhabited planets probably runs into the trillions. Some are close enough for us to detect evidence of life by analysing their atmospheres. This evidence may be found within a couple of decades. Its arrival will be momentous. But even before it arrives we can anticipate what life elsewhere will be like by examining the ecology and evolution of life on Earth. This book considers the current state of play in relation to these titanic issues.
Written for all therapists who want to understand this groundbreaking theory as it might actually show up in their day-to-day practice, this book offers a comprehensive approach to polyvagal-informed intervention. Worksheets and experiential exercises designed to map and shape autonomic response provide therapists with a road map for bringing polyvagal theory into their clinical practice.
The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?
From an award-winning medic and scientist, the game-changing case that genetic females have greater resilience, immunity, endurance and more, compared with males 'A powerful antidote to the myth of a "weaker sex"' Gina Rippon, author of The Gendered Brain From birth, genetic females are better at fighting viruses, infections and cancer. They do better at surviving epidemics and famines. They live longer, and even see the world in a wider variety of colours. These are the facts; they are simply stronger than men at every stage of life. Why? And why are we taught the opposite? Drawing on his wide-ranging experience and cutting-edge research as a medic, geneticist and specialist in rare diseases, Dr Sharon Moalem set out to understand why women are consistently more likely than men to thrive. The answer, he reveals, lies in our genetics: the female's double XX chromosomes offer a powerful survival advantage. Moalem explains why genetic females outperform males when it comes to immunity, resilience, stamina and much more. And he calls for a long-overdue reconsideration of our male-centric, one-size-fits-all view of the body and of how we prescribe medications - a view that still frames women through the lens of men. Revolutionary, captivating and utterly persuasive, The Better Half will make you see women, men and the survival of our species anew.
Genes and the traits they produce are passed down because in general they have or had an evolutionary purpose. Sometimes just knowing that a problem you have is inbuilt and part of a genetic package can be helpful in the way you deal with it. This volume is a useful guide for anyone who wants to learn more about how genes affect them and their family's everyday lives. Structured around the human life cycle - starting with babies and ending with death - this title addresses issues such as the determination of personality and physical characteristics, the likelihood of disease, sex and risk-taking. In conjunction with research into family history and awareness of personal strengths and weaknesses, this book can help readers to maximize their environment and avoid problems.
The Compact Guide: DNA provides a fascinating look at the world of the double helix and examines who we are, how we're wired, and how we repair ourselves. With information on so-called 'junk' DNA, how our genes evolved, heritability, the genetics of neuroscience, viruses, disease and what happens when things go wrong, this is a beautiful, visual journey through the polymer chain. The Compact Guide: DNA is an engaging and essential read for anyone captivated by the scope of human discovery, and reveals how we might just uncover the answers to the secrets of life on Earth.
