Selfie - How We Became So Self-Obsessed And What It's Doing To Us (Paperback): Will Storr Selfie - How We Became So Self-Obsessed And What It's Doing To Us (Paperback)
Will Storr 1
R330 R283 Discovery Miles 2 830 Save R47 (14%) Shipped within 4 - 8 working days

We live in an age of perfectionism.

Every day, we’re bombarded with the beautiful, successful, slim, socially-conscious and extroverted individual that our culture has decided is the perfect self. We see this person constantly in shop windows, in newspapers, on the television, at the movies and all over our social media. We berate ourselves when we don’t match up to them – when we’re too fat, too old, too poor or too sad. This cycle can be extremely bad for us. In recent years, psychologists have even begun to think that many people take their own lives because of the impossible standards that are set for who they ought to be.

Will Storr began to wonder about this perfect self that torments so many of us. Who, actually, is this person? Why does it hold such power over us? Could it be humanity’s deadliest idea? And, if so, is there any way we can break its spell? To find out, Storr takes us on a journey from the shores of Ancient Greece, through the Christian Middle Ages, the encounter groups of 1960s California and self-esteem evangelists of the late twentieth century to modern-day America, where research suggests today’s young people are in the grip of an epidemic of narcissism. He’ll tell the strange story of the individualist Western self from its birth on the Aegean to the era of hyper-individualistic neoliberalism in which we find ourselves today.

Selfie reveals, for the first time, the epic tale of the person we all know so intimately . . . because it’s us.

Youth Revolution - #BeTheChange (Paperback): Kiara Nirghin Youth Revolution - #BeTheChange (Paperback)
Kiara Nirghin
R210 R165 Discovery Miles 1 650 Save R45 (21%) Shipped within 4 - 8 working days

Youth Revolution is the inspirational story of how a sixteen-year-old high-school student from Johannesburg, Kiara Nirghin, overcame huge health obstacles to win the grand prize at the 2016 International Google Science Fair for her unique and innovative solution to worldwide drought. Having experienced bacterial meningitis, undiagnosed bilharzia and severe weight loss, Kiara was forced to postpone her school career for hospitalisation, with a real chance of losing her hearing, her sight and the use of her limbs.

Youth Revolution not only covers her journey from the hospital bed to the stage as the winner of the science award, but also looks at issues surrounding stagnant youth innovation, while considering the dangers of lacking diversity in STEM (science, technology, engineering and maths). It also includes contributions from prominent women in science and education, among them Malala Yousafzai, VP of Education and University Programs for Google and the recipient of the L’Oral-UNESCO Award for Women in Science.

Youth Revolution is a deeply human and truly inspirational real-life story that will enthral teenagers and adults alike, and proves that even ‘ordinary’ teenagers can do extraordinary things.

Ons weet dat die maan iets met die getye te doen het, maar het jy geweet dat jy met volmaan altyd dieselfde kant van die maan sien? Of dat weerligstrale vol vernietigende elektrisiteit is, maar dat ’n elektriese paling ’n lading van tot 600 volt kan vrystel?

Hierdie feite is deel van ’n magdom kennis oor die natuur, fisiese wetenskap en die ruimte wat die RSG-program Hoe verklaar jy dit? reeds jare lank beantwoord. Hierdie publikasie bevat ’n keur uit die honderde vrae van nuuskierige luisteraars wat deur kundiges verduidelik is om die wreld minder vreemd te maak, want nie alle kennis van die wreld om ons is voor die hand liggend nie. Daar is honderde verskynsels in die natuur en ruimte wat vra om verklaar te word. Dan praat ons nie eens van die mensgemaakte uitvindings soos die internet, persoonlike rekenaars, globale posisioneringstelsels, selfone, radiogolwe, teorie van evolusie, relatiwiteitsteorie, narkose en mense in die ruimte nie. Agter die alledaagse skuil die fassinerende werking van kragte en wette en die wetenskap in werking: Wat bepaal dat ’n mens se hart aan die linkerkant van die liggaam sit? Hoekom vries water in ’n dam van bo en nie van onder af nie? Kan gene deur omstandighede gemodifiseer word?

Hoe Verklaar Jy Dit? is ’n boek wat jou belangstelling in die wreld om jou sal prikkel. Dit is ’n boek wat op sy eie gelees kan word, wat op die koffietafel kan l en wat saam kan gaan kamp om wonderlike gesprekke om die braaivleisvuur uit te lok.

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 relmaat soetsappige, sogenaamd godsdienstige, pleisters plak.
  • Diegene wat reeds ons Kerk tot die ashoop van die geloof verdoem het.

When Edwin Hubble looked into his telescope in the 1920s, he was shocked to find that nearly all of the galaxies he could see through it were flying away from one another. If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin?

Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from. In The Origin of (almost) Everything, New Scientist explores the modern origin stories of everything from the Big Bang, meteorites and dark energy, to dinosaurs, civilisation, timekeeping, belly-button fluff and beyond.

From how complex life evolved on Earth, to the first written language, to how humans conquered space, The Origin of (almost) Everything offers a unique history of the past, present and future of our universe.

R360 R306 Discovery Miles 3 060 Save R54 (15%) Shipped within 4 - 8 working days

From the best-selling, award-winning author of 1491 and 1493--an incisive portrait of the two little-known twentieth-century scientists, Norman Borlaug and William Vogt, whose diametrically opposed views shaped our ideas about the environment, laying the groundwork for how people in the twenty-first century will choose to live in tomorrow's world.

In forty years, Earth's population will reach ten billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups--Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin. Cut back! was his mantra. Otherwise everyone will lose! The Wizards are the heirs of Norman Borlaug, whose research, in effect, wrangled the world in service to our species to produce modern high-yield crops that then saved millions from starvation. Innovate! was Borlaug's cry. Only in that way can everyone win!

Mann delves into these diverging viewpoints to assess the four great challenges humanity faces--food, water, energy, climate change--grounding each in historical context and weighing the options for the future. With our civilization on the line, the author's insightful analysis is an essential addition to the urgent conversation about how our children will fare on an increasingly crowded Earth.

Known as the `four horsemen' of New Atheism, these four big thinkers of the twenty-first century met only once. Their electrifying examination of ideas on this remarkable occasion was intense and wide-ranging. Everything that was said as they agreed and disagreed with one another, interrogated ideas and exchanged insights - about religion and atheism, science and sense - speaks with urgency to our present age.

Questions they asked of each other included:

  • Is it ever possible to win a war of ideas?
  • Is spirituality the preserve of the religious?
  • Are there any truths you would rather not know?
  • Would you want to see the end of faith?

The dialogue was recorded, and is now transcribed and presented here with new introductions from the surviving three horsemen. With a sparkling introduction from Stephen Fry, it makes essential reading for all their admirers and for anyone interested in exploring the tensions between faith and reason.

We all know South Africa has problems; we read about them in the newspapers, we see them on the streets and many people experience them in their daily lives. Fortunately, many of these problems can be solved using innovation and science. Innovation takes a look at inventions - developed in South Africa by South Africans - to address issues in the areas of healthcare, energy, environment and industry. Some of these inventions, such as a tea bag created to filter water for communities in rural areas, can save lives; others, such as a unique way to beneficiate titanium, could spell a new era of industry in the country.

The book is broken down into sections on environment, health, energy, industry and education, and in each of those parts are examples of South African innovations, from a satellite system to map fires to the concept of sterilising mosquitoes to stop the spread of malaria.

These have been developed by numerous organisations and institutions and showcase South Africa's excellence.

From the Sunday Times top ten bestselling author of The Psychopath Test, comes a captivating and brilliant exploration of one of our world's most underappreciated forces: shame. 'It's about the terror, isn't it?' 'The terror of what?' I said. 'The terror of being found out.'

For the past three years, Jon Ronson has travelled the world meeting recipients of high-profile public shamings. The shamed are people like us - people who, say, made a joke on social media that came out badly, or made a mistake at work. Once their transgression is revealed, collective outrage circles with the force of a hurricane and the next thing they know they're being torn apart by an angry mob, jeered at, demonized, sometimes even fired from their job. A great renaissance of public shaming is sweeping our land. Justice has been democratized. The silent majority are getting a voice. But what are we doing with our voice?

We are mercilessly finding people's faults. We are defining the boundaries of normality by ruining the lives of those outside it. We are using shame as a form of social control. Simultaneously powerful and hilarious in the way only Jon Ronson can be, So You've Been Publicly Shamed is a deeply honest book about modern life, full of eye-opening truths about the escalating war on human flaws - and the very scary part we all play in it.

In 2011, Tim Cook took on an impossible task - following in the footsteps of one of history's greatest business visionaries, Steve Jobs. Facing worldwide scrutiny, Cook (who was often described as shy, unassuming and unimaginative) defied all expectations. Under Cook's leadership Apple has soared: its stock has nearly tripled to become the world's first trillion-dollar company. From the massive growth of the iPhone to new victories like the Apple Watch, Cook is leading Apple to a new era of success.

But he's also spearheaded a cultural revolution within the company. Since becoming CEO, Cook has introduced a new style of management that emphasizes kindness, collaboration and honesty, and has quietly pushed Apple to support sexual and racial equal rights and invest heavily in renewable energy.

Drawing on authorized access with several Apple insiders, Kahney, the world's leading reporter on Apple, tells the inspiring story of how one man attempted to replace the irreplaceable and succeeded better than anyone thought possible.

Leander Kahney has covered Apple for more than a dozen years and has written four popular books about Apple and the culture of its followers, including Inside Steve's Brain and Jony Ive. The former news editor for Wired.com, he is currently the editor and publisher of CultofMac.com. He lives in San Francisco.

A building rock when its resonant frequency matches a gym class leaping to Snap's 1990 hit I've Got The Power? The answer is maths. Or, to be precise, what happens when maths goes wrong in the real world. As Matt Parker shows us, our modern lives are built on maths: computer programmes, finance, engineering. And most of the time this maths works quietly behind the scenes, until ... it doesn't. Exploring and explaining a litany of glitches, near-misses and mishaps involving the internet, big data, elections, street signs, lotteries, the Roman empire and a hapless Olympic shooting team, Matt Parker shows us the bizarre ways maths trips us up, and what this reveals about its essential place in our world. Mathematics doesn't have good 'people skills', but we would all be better off, he argues, if we saw it as a practical ally. This book shows how, by making maths our friend, we can learn from its pitfalls. It also contains puzzles, challenges, geometric socks, jokes about binary code and three deliberate mistakes. Getting it wrong has never been more fun.

Will a computer ever compose a symphony, write a prize-winning novel, or paint a masterpiece? And if so, would we be able to tell the difference? As humans, we have an extraordinary ability to create works of art that elevate, expand and transform what it means to be alive. Yet in many other areas, new developments in AI are shaking up the status quo, as we find out how many of the tasks humans engage in can be done equally well, if not better, by machines. But can machines be creative? Will they soon be able to learn from the art that moves us, and understand what distinguishes it from the mundane? In The Creativity Code, Marcus du Sautoy examines the nature of creativity, as well as providing an essential guide into how algorithms work, and the mathematical rules underpinning them. He asks how much of our emotional response to art is a product of our brains reacting to pattern and structure, and exactly what it is to be creative in mathematics, art, language and music. Marcus finds out how long it might be before machines come up with something creative, and whether they might jolt us into being more imaginative in turn. The result is a fascinating and very different exploration into both AI and the essence of what it means to be human.

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?

THE #1 SUNDAY TIMES BESTSELLER The bestselling author of Seven Brief Lessons on Physics takes us on an enchanting, consoling journey to discover the meaning of time 'We are time. We are this space, this clearing opened by the traces of memory inside the connections between our neurons. We are memory. We are nostalgia. We are longing for a future that will not come' Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe. With his extraordinary charm and sense of wonder, bringing together science, philosophy and art, Carlo Rovelli unravels this mystery. Enlightening and consoling, The Order of Time shows that to understand ourselves we need to reflect on time -- and to understand time we need to reflect on ourselves.

SHORTLISTED FOR THE ROYAL SOCIETY SCIENCE BOOK PRIZE 2018 Bestselling author Simon Winchester writes a magnificent history of the pioneering engineers who developed precision machinery to allow us to see as far as the moon and as close as the Higgs boson. Precision is the key to everything. It is an integral, unchallenged and essential component of our modern social, mercantile, scientific, mechanical and intellectual landscapes. The items we value in our daily lives - a camera, phone, computer, bicycle, car, a dishwasher perhaps - all sport components that fit together with precision and operate with near perfection. We also assume that the more precise a device the better it is. And yet whilst we live lives peppered and larded with precision, we are not, when we come to think about it, entirely sure what precision is, or what it means. How and when did it begin to build the modern world? Simon Winchester seeks to answer these questions through stories of precision's pioneers. Exactly takes us back to the origins of the Industrial Age, to Britain where he introduces the scientific minds that helped usher in modern production: John `Iron-Mad' Wilkinson, Henry Maudslay, Joseph Bramah, Jesse Ramsden, and Joseph Whitworth. Thomas Jefferson exported their discoveries to the United States as manufacturing developed in the early twentieth century, with Britain's Henry Royce developing the Rolls Royce and Henry Ford mass producing cars, Hattori's Seiko and Leica lenses, to today's cutting-edge developments from Europe, Asia and North America. As he introduces the minds and methods that have changed the modern world, Winchester explores fundamental questions. Why is precision important? What are the different tools we use to measure it? Who has invented and perfected it? Has the pursuit of the ultra-precise in so many facets of human life blinded us to other things of equal value, such as an appreciation for the age-old traditions of craftsmanship, art, and high culture? Are we missing something that reflects the world as it is, rather than the world as we think we would wish it to be? And can the precise and the natural co-exist in society?
