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.
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.
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.
'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.

'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.
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.

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] beautifully written investigation of grief ... As an exploration of love and loss, as a portrait of a person and of the nature of personhood, this book is about as true as any I have read' James McConnachie, Sunday Times An audacious and beautiful account of grief and who we are. Memoir, neuroscience and myth interweave to create a book unlike any other When celebrated neuropsychologist Paul Broks' wife died of cancer, he found himself plunged into the world of the bereaved. As he experienced the pain, alienation and suffering that make us human, his clinician-self seemed to watch on with keen interest. He embarked upon a voyage of experience: a journey through grief, philosophy, consciousness, humanity and magical thinking - seen through the prism of a lifetime's work in neuroscience. Fusing an account of living with and recovering from loss with thought-provoking meditations on the nature of the mind and the self, The Darker the Night, the Brighter the Stars is an audacious and beautiful work by a writer of astonishing wisdom and compassion.
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
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.
`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
Large-scale, interoperable biobanks are an increasingly important asset in today's life science research and, as a result, multiple types of biobanks are being established around the globe with very different financial, organizational and legal set-ups. With interdisciplinary chapters written by lawyers, sociologists, doctors and biobank practitioners, Global Genes, Local Concerns identifies and discusses the most pressing issues in contemporary biobanking. This timely book addresses pressing questions such as: how do national biobanks best contribute to translational research?; What are the opportunities and challenges that current regulations present for translational use of biobanks?; How does inter-biobank coordination and collaboration occur on various levels?; and how could academic and industrial exploitation, ownership and IPR issues be addressed and facilitated? Identifying that biobanks' foundational and operational set-ups should be legally and ethically sound, while at the same time reflecting the hopes and concerns of all the involved stakeholders, this book contributes to the continued development of international biobanking by highlighting and analysing the complexities in this important area of research. Academics in the fields of law and ethics, health law and biomedical law, as well as biobank managers and policymakers will find this insightful book a stimulating and engaging read.
'Wonderful ... Illuminating ... Fun to read' Daniel Kahneman, author of Thinking, Fast and Slow A pioneer of artificial intelligence shows how the study of causality revolutionized science and the world 'Correlation does not imply causation.' This mantra was invoked by scientists for decades in order to avoid taking positions as to whether one thing caused another, such as smoking and cancer and carbon dioxide and global warming. But today, that taboo is dead. The causal revolution, sparked by world-renowned computer scientist Judea Pearl and his colleagues, has cut through a century of confusion and placed cause and effect on a firm scientific basis. Now, Pearl and science journalist Dana Mackenzie explain causal thinking to general readers for the first time, showing how it allows us to explore the world that is and the worlds that could have been. It is the essence of human and artificial intelligence. And just as Pearl's discoveries have enabled machines to think better, The Book of Why explains how we can think better.
Of all species that have ever existed on earth, only one has reached human levels of intelligence and social organisation: us. Why? In Genesis, celebrated biologist Edward O. Wilson traces the great transitions of evolution, from the origin of life to the invention of sexual reproduction to the development of language itself. The only way for us to fully understand human behaviour, Wilson argues, is to study the evolutionary histories of nonhuman species. Of these, he demonstrates that at least seventeen - from the African naked mole rat and the sponge-dwelling shrimp to one of the oldest species on earth, the termite - have been found to have advanced societies based on altruism, cooperation and the division of labour. These rare eusocial species form the prehistory to our human social patterns, even, according to Wilson, suggesting the possible biological benefits of homosexuality and elderly grandmothers. Whether writing about midges who dance about like acrobats, schools of anchovies who protectively huddle to appear like a gigantic fish or well-organised flocks becoming potentially immortal, Genesis is a pathbreaking work of evolutionary theory filled with lyrical observations. It will make us rethink how we became who we are.work of evolutionary theory filled with lyrical observations. It will make us rethink how we became who we are.
'Acute, mind-opening, highly accessible - this book doesn't just explain how our lives might pan out, it helps us live better.' Bettany Hughes So many of us believe that we are free to shape our own destiny. But what if free will doesn't exist? What if our lives are largely predetermined, hardwired in our brains - and our choices over what we eat, who we fall in love with, even what we believe are not real choices at all? Neuroscience is challenging everything we think we know about ourselves, revealing how we make decisions and form our own reality, unaware of the role of our unconscious minds. Did you know, for example, that: * You can carry anxieties and phobias across generations of your family? * Your genes and pleasure and reward receptors in your brain will determine how much you eat? * We can sniff out ideal partners with genes that give our offspring the best chance of survival? Leading neuroscientist Hannah Critchlow draws vividly from everyday life and other experts in their field to show the extraordinary potential, as well as dangers, which come with being able to predict our likely futures - and looking at how we can alter what's in store for us. Lucid, illuminating, awe-inspiring The Science of Fate revolutionises our understanding of who we are - and empowers us to help shape a better future for ourselves and the wider world.
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'
Over 7 billion people depend on plants for healthy, productive, secure lives, but few of us stop to consider the origin of the plant kingdom that turned the world green and made our lives possible. And as the human population continues to escalate, our survival depends on how we treat the plant kingdom and the soils that sustain it. Understanding the evolutionary history of our land floras, the story of how plant life emerged from water and conquered the continents to dominate the planet, is fundamental to our own existence. In Making Eden David Beerling reveals the hidden history of Earth's sun-shot greenery, and considers its future prospects as we farm the planet to feed the world. Describing the early plant pioneers and their close, symbiotic relationship with fungi, he examines the central role plants play in both ecosystems and the regulation of climate. As threats to plant biodiversity mount today, Beerling discusses the resultant implications for food security and climate change, and how these can be avoided. Drawing on the latest exciting scientific findings, including Beerling's own field work in the UK, North America, and New Zealand, and his experimental research programmes over the past decade, this is an exciting new take on how plants greened the continents.
