This book is a totally fresh approach to observing birds in southern Africa. It affords you the opportunity to gather previously inaccessible and indecipherable information in the form of tracks and signs left behind by our avifauna. The book explores the unique details of the spoor, or tracks, of many species of birds. This is done in multiple ways including by observing their droppings, examining their feeding behaviour as well as their general nesting structures.
It’s remarkable how tracks and signs in nature help you to enrich your knowledge of bird species, providing knowledge as straightforward as the shape of the individual nests of our various species of weaver, or the ability to recognise and understand the role of a drum-site in the life of a bearded woodpecker, or even being able to see the subtle signs of a cardinal woodpecker on the various acacia pods which host its larval food.
Louis Liebenberg has generously provided some sketches of spoor he has made for his own publications, making these clear schematics available to assist with identification. Skulls, feathers, beaks and egg shells are also occasionally encountered, and a few examples of these will be included, as they also tell a story of a bird which has passed by. This approach to southern Africa’s birdlife will add tremendously to how we experience our wonderful avifauna.
A virologist's insight into how viruses evolve and why global epidemics are inevitable.
In 1993 a previously healthy young man was drowning in the middle of a desert, in fluids produced by his own lungs. This was the beginning of the terrifying Sin Nombre hantavirus epidemic and the start of a scientific journey that would forever change our understanding of what it means to be human. After witnessing the Sin Nombre outbreak, Dr Frank Ryan began researching viral evolution and was astonished to discover that it's inextricable from the evolution of all life on Earth. From AIDS and Ebola to the common cold, Ryan explores the role of the virus within every ecosystem on the planet.
His gripping conclusions shed new light on the natural world, proving that what doesn't kill you really does make you (and your species) stronger.
An Introduction To Scholarship offers a practical, skills-based approach to developing the basic academic and critical thinking skills required to succeed in the tertiary environment.
When was the last time you listened to someone, or someone really listened to you?
This life-changing book will transform your conversations forever
As a society, we’ve forgotten how to listen. Modern life is noisy and frenetic, and technology provides constant distraction. So we tune things out or listen selectively – even to those we love most. We’ve become scared of other people’s points of view, and of silence.
Now more than ever, we need to listen to those around us. New York Times contributor Kate Murphy draws on countless conversations she has had with everyone from priests to CIA interrogators, focus group moderators to bartenders, her great-great aunt to her friend's toddler, to show how only by listening well can we truly connect with others.
Listening is about curiosity and patience – about asking the right questions in the right way. Improvisational comedians and con men are much better at it than most of us. And the cleverest people can be the worst at it. Listening has the potential to transform our relationships and our working lives, improve our self-knowledge, and increase our creativity and happiness. While it may take some effort, it's a skill that can be learnt and perfected.
When all we crave is to understand and be understood, You're Not Listening shows us how.

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.

Now he turns his attention inwards to explore the human body, how it functions and its remarkable ability to heal itself.
Full of extraordinary facts and astonishing stories, The Body- A Guide for Occupants is a brilliant, often very funny attempt to understand the miracle of our physical and neurological make up. A wonderful successor to A Short History of Nearly Everything, this book will have you marvelling at the form you occupy, and celebrating the genius of your existence, time and time again.
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’Oréal-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.
A journey through the history and science of epidemics and pandemics – from measles to coronavirus.
For centuries mankind has waged war against the infections that, left untreated, would have the power to wipe out communities, or even entire populations. Yet for all our advanced scientific knowledge, only one human disease – smallpox – has ever been eradicated globally. In recent years, outbreaks of Ebola and Zika have provided vivid examples of how difficult it is to contain an infection once it strikes, and the panic that a rapidly spreading epidemic can ignite.
But while we chase the diseases we are already aware of, new ones are constantly emerging, like the coronavirus that spread across the world in 2020. At the same time, anti-microbial resistance is harnessing infections that we once knew how to control, enabling them to thrive once more.
Meera Senthilingam presents a timely look at humanity’s ongoing battle against infection, examining the successes and failures of the past, along with how we are confronting the challenges of today, and our chances of eradicating disease in the future.
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.

In this book, Adrian Koopman describes the complex relationship between birds, the Zulu language and Zulu culture. A number of chapters look at the underlying meaning of bird names, and here we will find that the Zulu name of the Goliath Heron means ‘what gives birth to baby crocodiles’, the dikkop (umbangaqhwa) means ‘what causes frost’, and the African Hoopoe is a party-goer who wears a colourful blanket.
The book goes further than just Zulu names, exploring the underlying meanings of bird names from other South African languages and languages from Central and East Africa. Here we find birds with names that translate as ‘cool-porridge’, ‘kiss-banana-flower’ and ‘waiter-at-the-end-of-the furrow’.
A focus on Zulu traditional oral literature details the roles birds have played in Zulu praise poetry (including the praise poems of certain birds themselves) and in proverbs, riddles and children’s games. Also considered is traditional bird lore, examining the role played by various species as omens and portents, as indicators of bad luck and evil, as forecasters of rain and storm, and as harbingers of the seasons. Here we see that the Bateleur Eagle (ingqungqulu) is linked to war, the Southern Ground Hornbill (insingizi) to thunder and heavy rain, the Red-chested Cuckoo (uphezukokhono) to the start of the ploughing season, and the Jacobin Cuckoo (inkanku) to the start of summer.
Zulu Bird Names and Bird Lore discusses the Zulu Bird Name Project, a series of Zulu bird name workshops held between 2013 and 2017 with Zulu-speaking bird guides designed to confirm (or otherwise) all previously recorded Zulu names for birds, while at the same time devising new names for those without previously recorded names. The result has been a list of species-specific names for all birds in the Zulu-speaking region. Finally, the book turns to the role such new bird names can play in conservation education and in avi-tourism.

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.
In this scientifically informed account of the changes occurring in the world over the last century, award-winning broadcaster and natural historian Sir David Attenborough shares a lifetime of wisdom and a hopeful vision for the future.
See the world. Then make it better.
I am 93. I've had an extraordinary life. It's only now that I appreciate how extraordinary.
As a young man, I felt I was out there in the wild, experiencing the untouched natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable from day to day -- the loss of our planet's wild places, its biodiversity. I have been witness to this decline. A Life on Our Planet is my witness statement, and my vision for the future. It is the story of how we came to make this, our greatest mistake -- and how, if we act now, we can yet put it right.
We have one final chance to create the perfect home for ourselves and restore the wonderful world we inherited. All we need is the will do so.
This text aims to differentiate itself from other business statistics texts in two important ways. It seeks: to present the material in a non-technical manner to make it easier for a student with limited mathematical background to grasp the subject matter; and to develop an intuitive understanding of the techniques by framing them in the context of a management question, giving layman-type explanations of methods, using illustrative business examples and focusing on the management interpretations of the statistical findings. This further edition continues the theme of using Excel as a computational tool to perform statistical analysis. While all statistical functions have been adjusted to the Excel (2013) format, the statistical output remains unchanged. Using Excel to perform the statistical analysis in this text allows a student: To examine more realistic business problems with larger datasets; To focus more on the statistical interpretation of the statistical findings; and to transfer this skill of performing statistical analysis more easily to the work environment. Its overall purpose is to develop a management student's statistical reasoning and statistical decision-making skills to give him or her a competitive advantage in the workplace.
Everything you need to know about race (but were afraid to ask), previously published in 2015 as Black Brain, White Brain: Is Intelligence Skin Deep?.
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.
What makes us brilliant? What makes us deadly? What makes us Sapiens? Yuval Noah Harari challenges everything we know about being human in the perfect read for these unprecedented times.
Earth is 4.5 billion years old. In just a fraction of that time, one species among countless others has conquered it: us.
In this bold and provocative book, Yuval Noah Harari explores who we are, how we got here and where we’re going.
‘I would recommend Sapiens to anyone who’s interested in the history and future of our species’ Bill Gates
‘Interesting and provocative… It gives you a sense of how briefly we’ve been on this Earth’ Barack Obama
Are we really just the result of innumerable coincidences? Or is there a more reasonable explanation?
Most of us remember the basics from science classes about how Earth came to be the only known planet that sustains complex life. But what most people don't know is that the more thoroughly researchers investigate the history of our planet, the more astonishing the story of our existence becomes.
The number and complexity of the astronomical, geological, chemical, and biological features recognized as essential to human existence have expanded explosively within the past decade. An understanding of what is required to make possible a large human population and advanced civilizations has raised profound questions about life, our purpose, and our destiny.
This fascinating book helps non-scientists understand the countless miracles that undergird the exquisitely fine-tuned planet we call home--as if Someone had us in mind all along.
This book introduces the fundamentals of financial mathematics.
It begins with a discussion of simple and compound interest and then establishes the important concepts of effective and equivalent effective interest rates. Subsequent chapters discuss the applications of annuities to practical problems regarding the saving of money and repayment of loans. The notion of using net present value and internal rate of return to distinguish between two different investment opportunities is presented.
The concluding chapters of the book take a brief look at the use of differential and integral calculus in financial mathematics. Each chapter includes numerous worked examples that are solved with the aid of a financial calculator where applicable.
Fascinating, engaging, and extremely visual, FOUNDATIONS OF ASTRONOMY, Enhanced Thirteenth Edition, is renowned for its current coverage, reader-friendly presentation, and detailed, yet clear explanations. The authors' goals are to help you use astronomy to understand science-and use science to answer two fundamental questions: What are we? And how do we know?
