Na die ongelooflike sukses van RSG se Hoe Verklaar Jy Dit? is dit niks minder as gepas om met hierdie tweede volume Suid-Afrikaners se nuuskierigheid oor die wêreld verder te bevredig nie.
In Hoe Verklaar Jy Dit? 2 bring Danny Fourie weer ’n gerf van die interessantste vrae en antwoorde byeen wat deur RSG se kundige medewerkers in die gewilde radioprogram behandel is. En dit help die leser natuurlik om die wêreld om ons minder vreemd te maak. Hoe verklaar jy ons honger na inligting en ons dors na kennis? Die antwoord is eenvoudig: Ons is mal daaroor om antwoorde te kry, selfs al is daar geen oënskynlike voordeel daarin nie.
Is dit werklik nodig om te weet wat ’n Jerusalem-kriek of ’n sweepspinnekop is? Waarom die son nie uitbrand nie? Hoekom ’n mens se oë traan as jy uie sny? Hoe die Richter-skaal werk? Wie en wat die Florisbadmens is? Wat links- en regshandigheid bepaal? Van al die soogdiere is ons die enigste wat lewenslank nuuskierig bly. Daarom sal Hoe Verklaar Jy Dit? 2 jou nog meer fassineer.
We know that the moon influences the tides, but did you know that with the full moon, you always see the same side of the moon? Or that a yawn is contagious for humans and some animals? And what precisely causes birds not to bump into one another when they fly in a swarm and they swerve? These facts are part of a massive amount of knowledge about nature, physics and space that the RSG programme Hoe verklaar jy dit? has been sharing for 37 years. This book, translated from the original, bestselling Afrikaans version, contains a selection from the hundreds of questions curious listeners have been asking the experts to answer in order to make the world a little less strange, because not all knowledge is obvious. There are so many wonderful enigmas in nature and space that beg to be explained – and we won’t even mention man-made inventions! How Do You Explain That? will pique your interest in the world around you. It is a book that can be enjoyed on its own, or can lie on the coffee table, or can go camping with the family to elicit wonderful conversations around the campfire.
Almost Human is the personal story of a charismatic and visionary palaeontologist, a rich and readable narrative about science, exploration, and what it means to be human.
In 2013, Wits University reasearch professor Lee Berger caught wind of a cache of bones in a hard-to-reach underground cave near Johannesburg. He put out a call around the world for collaborators – men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of ‘underground astronauts’, Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known pre-hominids with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species: Homo naledi.
The cave proved to be the richest pre-hominid site ever discovered, full of implications that challenge how we define ourselves as human. Did these ancestors of ours bury their dead? If so, they must have had an awareness of death, a level of self-knowledge: the very characteristic we used to define ourselves as human. Did an equally advanced species inhabit Earth with us, or before us?
Addressing these questions, Berger counters the arguments of those colleagues who have questioned his controversial interpretations and astounding finds.
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.

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 wêreld minder vreemd te maak, want nie alle kennis van die wêreld 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 wêreld om jou sal prikkel. Dit is ’n boek wat op sy eie gelees kan word, wat op die koffietafel kan lê 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.

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.

Made into a major motion picture, this moving memoir written by Stephen Hawking’s first wife covers the turbulent years of her marriage to the astrophysics genius, her traumatic divorce, and their recent reconciliation
Professor Stephen Hawking is one of the most famous and remarkable scientists of our age and the author of the scientific bestseller A Brief History of Time, which has sold more than 25 million copies. In this compelling memoir, his first wife, Jane Hawking, relates the inside story of their extraordinary marriage. As Stephen's academic renown soared, his body was collapsing under the assaults of a motor neuron disease. Jane's candid account of trying to balance his 24-hour care with the needs of their growing family reveals the inner strength of the author, while the self-evident character and achievements of her husband make for an incredible tale presented with unflinching honesty.
Jane's candor is no less apparent when the marriage finally ends in a high-profile meltdown, with Stephen leaving Jane for one of his nurses and Jane marrying an old family friend. In this exceptionally open, moving, and often funny memoir, Jane Hawking confronts not only the acutely complicated and painful dilemmas of her first marriage, but also the relationship's fault lines exposed by the pervasive effects of fame and wealth.
The result is a book about optimism, love, and change that will resonate with readers everywhere. readers everywhere.
Racist thinking – that intelligence is influenced by racial origin, for example – was part of mainstream science a century ago and, surprisingly, is still endorsed by maerick scientists at some of the world’s most respectable institutions today. The myths being perpetuated on genetics, race, IQ and general intelligence are what Black Brain, White Brain challenges – precisely, systematically and in painstaking detail.
In this immensely readable book Evans tackles highly complex subjects, from the origin of humans and the genesis of intelligence to athletic performance and genes, IQ and cleverness, in a fluent and engaging style that makes science accessible and the facts absorbing. Persuasive, without being didactic or sermonising, and lightened by a wry sense of humour, Evans’s text weaves it all together in such a way that one is keen to follow all the threads the better to see the larger tapestry.
Carefully balancing claims, testing dodgy propositions and presenting fairly the theories of modern scientists and evolutionary psychologists, Evans shows just how uniform we are, genetically, as a species and that it’s mainly the environment we grow up and live in that’s the strong determining factor in general intelligence.
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.
Chemistry, Seventh Edition provides the necessary practice, support, concept mastery and individualized instruction that ensure success in the General Chemistry course.
