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.
Longlisted for the National Book Award for Nonfiction and A New York Times Notable Book of 2018. Our understanding of the `tree of life', with powerful implications for human genetics, human health and our own human nature, has recently completely changed. This book is about a new method of telling the story of life on earth - through molecular phylogenetics. It involves a fairly simple method - the reading of the deep history of life by looking at the variation in protein molecules found in living organisms. For instance, we now know that roughly eight per cent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection. In The Tangled Tree, acclaimed science writer David Quammen chronicles these discoveries through the lives of the researchers who made them - such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about `mosaic' creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. Quammen explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life - including where we humans fit into it. Thanks to new technologies, we now have the ability to alter even our genetic composition - through sideways insertions, as nature has long been doing. The Tangled Tree is a brilliant exploration of our transformed understanding of evolution and of life's history itself.
An enchanting biography of the most resonant - and most necessary - chemical element on Earth. Carbon. It's in the fibres in your hair, the timbers in your walls, the food that you eat and the air that you breathe. It's worth billions as a luxury and half a trillion as a necessity, but there are still mysteries yet to be solved about the element that can be both diamond and coal. Where does it come from, what does it do, and why, above all, does life need it? With sparkling prose and engaging narrative, earth scientist Robert Hazen leads us on a vibrant journey through the origin and evolution of life's most ubiquitous element. The story unfolds in four movements - Earth, Air, Fire and Water - and transports us through 14 billion years of cosmic history. From the outer reaches of the universe to the cliffs of Scotland and into the precious-metal mines of Namibia, Symphony in C is a sweeping chronicle of carbon: the most essential element on Earth.
A cutting-edge examination of what it means to be human and to have a 'self' in the face of new scientific developments in genetic editing, cloning and neural downloading. After seeing his own cells used to grow clumps of new neurons - essentially mini-brains - Philip Ball begins to examine the concepts of identity and consciousness. Delving into humanity's deep evolutionary past to look at how complex creatures like us emerged from single-celled life, he offers a new perspective on how humans think about ourselves. In an age when we are increasingly encouraged to regard the 'self' as an abstract sequence of genetic information, or as a pattern of neural activity that might be 'downloaded' to a computer, he return us to the body - to flesh and blood - and anchors a conception of personhood in this unique and ephemeral mortal coil. How to Build a Human brings us back to ourselves - but in doing so, it challenges old preconceptions and values. It asks us to rethink how we exist in the world.
Bone is a marvel, an adaptable and resilient building material developed over 500 million years of evolutionary history. It has manifested itself in wings, sails, horns, armor, and an even greater array of appendages since the time of its origin. In dinosaur fossils, skeletons are biological time capsules that tell us of lives we'll never see in the flesh. Inherited from a common fishy ancestor, it is the stuff that binds all of us vertebrates together into one great family. Swim, slither, stomp, fly, dig, run - all are expressions of what bones make possible. But that's hardly all. In The Secret Life of Bone, Brian Switek frames the history of our species through the importance of bone from instruments and jewellery, to objects of worship and conquest from the origins of religion through the genesis of science and up through this very day. While bone itself can reveal our individual stories, the truth very much depends on who's telling it. Our skeletons are as embedded in our culture as they are in our bodies. Switek, an enthusiastic osteological raconteur, cuts through biology, history, and culture to understand the meaning of what's inside us and what our bones tell us about who we are, where we came from and the legacies we leave behind.
Walking upright on two feet is a uniquely human skill. It defines us as a species. It enabled us to walk out of Africa and to spread as far as Alaska and Australia. It freed our hands and freed our minds. We put one foot in front of the other without thinking - yet how many of us know how we do that, or appreciate the advantages it gives us? In this hymn to walking, neuroscientist Shane O'Mara invites us to marvel at the benefits it confers on our bodies and minds. In Praise of Walking celebrates this miraculous ability. Incredibly, it is a skill that has its evolutionary origins millions of years ago, under the sea. And the latest research is only now revealing how the brain and nervous system performs the mechanical magic of balancing, navigating a crowded city, or running our inner GPS system. Walking is good for our muscles and posture; it helps to protect and repair organs, and can slow or turn back the ageing of our brains. With our minds in motion we think more creatively, our mood improves and stress levels fall. Walking together to achieve a shared purpose is also a social glue that has contributed to our survival as a species. As our lives become increasingly sedentary, we risk all this. We must start walking again, whether it's up a mountain, down to the park, or simply to school and work. We, and our societies, will be better for it.
James Lovelock, creator of the Gaia hypothesis and the greatest environmental thinker of our time, has produced an astounding new theory about future of life on Earth. He argues that the anthropocene - the age in which humans acquired planetary-scale technologies - is, after 300 years, coming to an end. A new age - the novacene - has already begun. New beings will emerge from existing artificial intelligence systems. They will think 10,000 times faster than we do and they will regard us as we now regard plants - as desperately slow acting and thinking creatures. But this will not be the cruel, violent machine takeover of the planet imagined by sci-fi writers and film-makers. These hyper-intelligent beings will be as dependent on the health of the planet as we are. They will need the planetary cooling system of Gaia to defend them from the increasing heat of the sun as much as we do. And Gaia depends on organic life. We will be partners in this project. It is crucial, Lovelock argues, that the intelligence of Earth survives and prospers. He does not think there are intelligent aliens, so we are the only beings capable of understanding the cosmos. Maybe, he speculates, the novacene could even be the beginning of a process that will finally lead to intelligence suffusing the entire cosmos. At the age 100, James Lovelock has produced the most important and compelling work of his life.

'Mind-blowing ... It is a hugely important book ... His story is crucial' Matt Ridley, The Times One of the world's top behavioural geneticists argues that we need a radical rethink about what makes us who we are The blueprint for our individuality lies in the 1% of DNA that differs between people. Our intellectual capacity, our introversion or extraversion, our vulnerability to mental illness, even whether we are a morning person - all of these aspects of our personality are profoundly shaped by our inherited DNA differences. In Blueprint, Robert Plomin, a pioneer in the field of behavioural genetics, draws on a lifetime's worth of research to make the case that DNA is the most important factor shaping who we are. Our families, schools and the environment around us are important, but they are not as influential as our genes. This is why, he argues, teachers and parents should accept children for who they are, rather than trying to mould them in certain directions. Even the environments we choose and the signal events that impact our lives, from divorce to addiction, are influenced by our genetic predispositions. Now, thanks to the DNA revolution, it is becoming possible to predict who we will become, at birth, from our DNA alone. As Plomin shows us, these developments have sweeping implications for how we think about parenting, education, and social mobility. A game-changing book by a leader in the field, Blueprint shows how the DNA present in the single cell with which we all begin our lives can impact our behaviour as adults.

Charles Darwin's voyage on the HMS Beagle was a journey that would revolutionise our understanding of the natural world and our place in it. The magisterial work it spawned, On the Origin of Species, is widely associated with the flora and fauna of the Galapagos Islands. Less well known is Darwin's passion for geology and how his fossil discoveries in South America - by demonstrating the relationship between extinct lifeforms and living species - shaped his theory of evolution. This is the story of those fossil-hunting adventures in the 1830s, the pioneering science behind the fossils he found, and how these remarkable discoveries played a crucial role in forging Darwin's revolutionary ideas.
Explore ecology in this accessible introduction to how the natural world works and how we have started to understand the environment, ecosystems, and climate change. Using a bold, graphic-led approach, The Ecology Book explores and explains over 85 of the key ideas, movements, and acts that have defined ecology and ecological thought. The book has a simple chronological structure, with early chapters ranging from the ideas of classical thinkers through to attempts by Enlightenment thinkers to systematically order the natural world. Later chapters trace the evolution of modern thinking, from the ideas of Thomas Malthus, Henry Thoreau, and others, right the way through to the political and scientific developments of the modern era, including the birth of the environmental movement and the Paris Agreement. The ideal introduction to one of the most important subjects of our time.
A groundbreaking examination of human perception, reality and the evolutionary schism between the two Do we see the world as it truly is? In The Case Against Reality, pioneering cognitive scientist Donald Hoffman says no? we see what we need in order to survive. Our visual perceptions are not a window onto reality, Hoffman shows us, but instead are interfaces constructed by natural selection. The objects we see around us are not unlike the file icons on our computer desktops: while shaped like a small folder on our screens, the files themselves are made of a series of ones and zeros - too complex for most of us to understand. In a similar way, Hoffman argues, evolution has shaped our perceptions into simplistic illusions to help us navigate the world around us. Yet now these illusions can be manipulated by advertising and design. Drawing on thirty years of Hoffman's own influential research, as well as evolutionary biology, game theory, neuroscience, and philosophy, The Case Against Reality makes the mind-bending yet utterly convincing case that the world is nothing like what we see through our eyes.
The genetic history of the dog is a sensational example of the co-evolution of two species, man and wolf, to each other's mutual benefit. But how did this ancient partnership begin? To answer this question, Professor Bryan Sykes identifies tantalising clues in the recently mapped genetic makeup of both species. Sykes paints a vivid picture of the dog as an ancient and essential ally. While undoubtedly it was the mastery of fire, language and agriculture that propelled Homo sapiens from a scarce, medium-sized primate to the position we enjoy today, Sykes crucially credits a fourth element for this success: the transformation of the wolf into the multi-purpose helpmate that is the dog. Drawing upon archaeology, history and genetics, Sykes shows how humans evolved to become the dominant species on Earth, but only with the help of our canine companions.
'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.
By the author of the best-selling, prize-winning Stuff Matters 'A truly delightful read' Jim Al-Khalili, author of Paradox 'Exciting, anarchic and surprising' Katy Guest, The Guardian This fascinating new book by the bestselling scientist and engineer Mark Miodownik is an expert tour of the world of the droplets, heartbeats and ocean waves that we come across every day. Structured around a plane journey which sees encounters with substances from water and glue to coffee and wine, he shows how these liquids can bring death and destruction as well as wonder and fascination. From Laszlo Biro's revolutionary pen and Abraham Gesner's kerosene to cutting-edge research on self-repairing roads and liquid computers, Miodownik uses his winning formula of scientific storytelling to bring the everyday to life. He reveals why liquids can flow up a tree but down a hill, why oil is sticky, how waves can travel so far, and how to make the perfect cup of tea. Here are the secret lives of substances that we rely on but rarely understand. 'An exhilarating, eye-opening ride' Philip Ball, science writer and author of H2O 'A thrilling read, from start to finish' Tim Radford, author of The Consolations of Physics

As read by James Corden, Fearne Cotton, Jim Chapman and Dougie Poytner. 'We have a responsibility, every one of us' David Attenborough Around 12.7 million tonnes of plastic are entering the ocean every year, killing over 1 million seabirds and 100,000 marine mammals. By 2050 there could be more plastic in the ocean than fish by weight. Plastic pollution is the environmental scourge of our age, but how can YOU make a difference? This accessible guide, written by the campaigner at the forefront of the anti-plastic movement, will help you make the small changes that make a big difference, from buying a reusable coffee cup to running a clean-up at your local park or beach. Tips on giving up plastic include: * Washing your clothes within a wash bag to catch plastic microfibers (the cause of 30% of plastic pollution in the ocean) * Replacing your regular shampoo with bar shampoo * How to lobby your supermarket to remove unnecessary packaging * How to throw a plastic-free birthday party * How to convince others to join you in giving up plastic Plastic is not going away without a fight. We need a movement made up of billions of individual acts, bringing people together from all backgrounds and all cultures, the ripples of which will be felt from the smallest village to the tallest skyscrapers. This is a call to arms - to join forces across the world and to end our dependence on plastic. #BreakFreeFromPlastic Plastic is not going away without a fight. We need a movement made up of billions of individual acts, bringing people together from all backgrounds and all cultures, the ripples of which will be felt from the smallest village to the tallest skyscrapers. 'Plastic waste is one of the greatest environmental challenges facing the world' Theresa May 'As Head of Oceans at Greenpeace, Will is on the front line of humanity's global fight against plastic. This timely book not only explains how we got into this mess, but most importantly offers an optimistic and proactive approach as to how we can get out of it'. - Richard Walker, Managing Director at Iceland
Everything you need to know about race (but were afraid to ask). In academic journals and on internet message boards, certain scientists and thinkers are laying siege to one of the great taboos. Could it be, they ask, that racism has a rational basis in science? These ideas are no longer limited to the fringe: race-based studies of intelligence have been discussed by thinkers such as Steven Pinker, Sam Harris and Jordan Peterson. If true, it would provide an intellectual foundation for so many of the attitudes that characterise the right wing, justifying inequality and discrimination. Gavin Evans tackles the nature vs nurture debate head-on, examining the latest studies on how intelligence develops and laying out new discoveries in genetics, palaeontology, archaeology and anthropology to unearth the truth about our shared past. In doing so, Skin Deep demolishes the pernicious myth that our race is our destiny, and instead reveals what really makes us who we are.
A fascinating and practical guide from two New York Times bestselling authors, backed by state-of-the-art scientific research Drawing on cutting-edge research, friends and Harvard collaborators Daniel Goleman and Richard Davidson expertly reveal what we can learn from a one-of-a-kind data pool that includes world-class meditators. They share for the first time remarkable findings that show how meditation - without drugs or high expense - can cultivate qualities such as selflessness, equanimity, love and compassion, and redesign our neural circuitry. Demonstrating two master thinkers at work, The Science of Meditation explains precisely how mind training benefits us. More than daily doses or sheer hours, we need smart practice, including crucial ingredients such as targeted feedback from a master teacher and a more spacious worldview. These two bestselling authors sweep away the misconceptions around these practices and show how smart practice can change our personal traits and even our genome for the better. Gripping in its storytelling and based on a lifetime of thought and action, this is one of those rare books that has the power to change us at the deepest level. 'This is a book that really can change your life.' - Arianna Huffington, author of the 'New York Times' best seller 'The Sleep Revolution' 'A happy synthesis of the authors' remarkable careers' - Jon Kabat-Zinn, author of 'Full Catastrophe Living' and 'Mindfulness for Beginners' The definitive book on the science of meditation. Rigorously researched and deeply illuminating' - Daniel Gilbert, PhD, author of the New York Times bestseller 'Stumbling on Happiness' 'This exquisite duet between a down-to-earth science writer and path-breaking neuroscientist is a tour-de-force, revealing how training the mind can transform the brain and our sense of self, inspiring us to create a greater sense of well-being, meaning, and connection in our world. Bravo!' - Daniel J. Siegel, M.D., author of the 'New York Times' best sellers, 'Mind' and 'Brainstorm'
`Highly accessible...revolutionary to a glorious degree' Observer Reading maps or reading emotions? Barbie or Lego? Do you have a female brain or a male brain? Or is that the wrong question? We live in a gendered world where we are bombarded with messages about sex and gender. On a daily basis we face deeply ingrained beliefs that your sex determines your skills and preferences, from toys and colours to career choice and salaries. But what does this constant gendering mean for our thoughts, decisions and behaviour? And what does it mean for our brains? Drawing on her work as a professor of cognitive neuroimaging, Gina Rippon unpacks the stereotypes that bombard us from our earliest moments and shows how these messages mould our ideas of ourselves and even shape our brains. By exploring new, cutting-edge neuroscience, Rippon urges us to move beyond a binary view of our brains and instead to see these complex organs as highly individualised, profoundly adaptable, and full of unbounded potential. Rigorous, timely and liberating, The Gendered Brain has huge repercussions for women and men, for parents and children, and for how we identify ourselves. 'A treasure trove of information and good humour' Cordelia Fine, author of Delusions of Gender
