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.

Hierdie is 'n moet-lees boek vir:

• Lidmate wat ons Kerk graag wil help om 'n gesonde, geestelike tuiste vir Suid-Afrikaners van die 21ste eeu te bied.
• Die klakkelose napraters van die dogma wat dink ons Kerk is steeds op die regte pad.
• Die plastiekpredikante van die radio en televisie wat met eentonige reëlmaat soetsappige, sogenaamd godsdienstige, pleisters plak.
• Diegene wat reeds ons Kerk tot die ashoop van die geloof verdoem het.

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.

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.

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.

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

Darwin's theory of evolution was a monumental achievement, but there was much he did not know. In his `survival of the fittest' model each step must go forward, life always progressing up the slope towards an evolutionary peak. There is no turning back. So what happens when there is more than one slope, and life finds itself on the wrong one? World-leading biologist Andreas Wagner reveals that life does not, as Darwin believed, only walk - it also leaps. Drawing on pioneering research, Wagner explores life's creative process and how it bears a striking resemblance to how we humans work. A beguiling symmetry links Picasso struggling through forty versions of Guernica and the way evolution transformed a dinosaur's claw into a condor's wing. This new understanding is already revolutionising our approach to problem-solving across the sciences. In the near future, applied in spheres as diverse as the economy and education, it will enable us to do so much more. Thought-provoking and deeply hopeful, Life Finds a Way reminds us that no matter how many times we have to turn back, we can still reach the highest peaks.

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.

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

'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.

How to be Human is the only manual you need to help you upgrade your mind as much as you've upgraded your iphone. 'With this marvellous book, Ruby Wax has confirmed her position as one of the most readable, inspirational and engaging writers in the field of human mental health, happiness and fulfilment.' Stephen Fry "It took us 4 billion years to evolve to where we are now - completely brilliant and yet, some might say, emotionally dwarfed. The question is: can our more empathetic side catch up in time to save us and the world? I've got nothing against smarts, but it's smarts without emotional awareness that got us into this position of being able to nuke each other into oblivion and rape the earth for oil." With a little help from a monk (who tells us how our mind works) and a neuroscientist (who tells us how our brain works), Ruby Wax answers every question you've ever had about: evolution, thoughts, emotions, the body, addictions, relationships, sex, kids, the future and compassion. Filled with witty anecdotes from Ruby's own life, and backed up by smart science and practical mindfulness exercises, How to be Human is the only manual you need to help you upgrade your mind as much as you've upgraded your iphone. 'Ruby has beautifully fused neurology and spirituality and given us a means to cope with operating both a mind and a brain. If this mental upgrade works then all other books will become defunct as we repose in bliss.' Russell Brand 'How to Be Human is, without exaggeration, a lifeline; wise, practical and funny, it is a handbook for those in despair. It is actually for everyone alive, for the curious, or disillusioned or muddled or just plain happy.' Joanna Lumley

The story of the most significant biological breakthrough of the century - the discovery of the structure of DNA. 'It is a strange model and embodies several unusual features. However, since DNA is an unusual substance, we are not hesitant in being bold' By elucidating the structure of DNA, the molecule underlying all life, Francis Crick and James Watson revolutionised biochemistry. At the time, Watson was only 24. His uncompromisingly honest account of those heady days lifts the lid on the real world of great scientists, with their very human faults and foibles, their petty rivalries and driving ambition. Above all, he captures the extraordinary excitement of their desperate efforts to beat their rivals at King's College to the solution to one of the great enigmas of the life sciences.

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.

Are we our brains? How can you map the mind? Can brain scans read our minds?Based on Rob Newman's live stand-up show and new BBC Radio 4 series, his thought-provoking new book explores the scientific breakthroughs that have turned received ideas of brain science upside down. After imagining volunteering for a brain-imaging experiment meant to locate the part of the brain that lights up when you're in love, comedian Robert Newman emerged with more questions than answers. In Neuropolis Newman argues that the current claim that the brain is just a complicated computer derives from science, but from a combination of philosophical stowaways and a version of evolutionary biology that owes little to Darwin. He questions why brain science is devoted to such a peculiarly reductionist world view, when really exciting advances in neuroscience go untold, such as awe-inspiring discoveries about the origins of memory in ancient oceans. He also shows that our brains are inextricably and profoundly intertwined with our bodies, the natural world and the world we have made, including hilarious accounts of his own participation in neurological experiments. Debunking the common, even brainless interpretations of brain science, he celebrates the more intriguing and underreported advances in neuroscience with zest and wit.
