A series of glasses of transparent liquids is in front of you: but which will quench your thirst and which will kill you? And why? Why does one liquid make us drunk, and another power a jumbo jet?

From the bestselling author of Stuff Matters comes a fascinating tour of the world of these surprising or sinister substances - the droplets, heartbeats and ocean waves we encounter day-to-day. Structured around a plane journey which sees encounters with water, wine, and oil, among others, Miodownik shows that liquids are agents of death and destruction as well as substances of wonder and fascination. Just as in Stuff Matters his unique brand of scientific storytelling brings them and their mysterious properties alive in a captivating new way.

How do magnets work? What is the theory of relativity all about? Is light made of waves or particles? And how on earth can a levitating goat teach us about atomic structure? In this age of smartphones, artificial intelligence, supercolliders, supercomputers and other cutting-edge technology, we've lost touch with many of the most basic science concepts that launched our information age. For Bruce Benamren, science is about stories and characters. Why, for instance, did pirates wear eye patches? That's all to do with how the retina processes light. Pirates running down to the gun deck would have no time to let their eyes get used to the dark, so they kept one eye gun-deck ready. Bruce isn't pretending that science isn't tricky, but in simple, maths-free explanations and just-the-good-parts historical recaps, he shows us that the greatest scientific discoveries and theories don't have to remain beyond our grasp. Whether you haven't picked up a test tube since school and feel like you're missing out on something marvellous, or you're a professor who wants to look at the world with starry-eyed wonder again, How to Speak Science is a witty yet deeply revelatory exploration of the essential mysteries of the universe. Because if a goat can explain scientific theory, you can too.

The Universe came into being 13.8 billion years ago. At this point, all of existence could be summed up as an endless soup of particles frothing at temperatures many times hotter than the Sun. It was chaos. Fortunately, as the Universe expanded, everything began to cool and the particles stabilised. It was around this time, as disorder gave way to order, that the elements were born. Fast forward to June 2016 and the periodic table of elements was finally completed with the discovery and addition of four new elements. At last we could identify all the ingredients necessary to make a world. But it doesn't stop there. Human ingenuity knows no bounds; we have even begun to invent our own elements and have created an entire science devoted to their study: chemistry.

Discover the incredible potential of mankind's near future as a Doctor and a Philosopher debate the big questions surrounding the incredible potential of trans-humanism. This movement - that seeks to improve the human condition through science - has fast become one of the most controversial the scientific community have ever faced. As scientists in California make great strides in using advanced technology to enhance human intellect and physiology, the ethical and moral questions surrounding its possibilities have never been more pressing. Should we change the way we reproduce? Could we enhance the human body with technology to the point where we are all technically cyborgs? Is it possible to make love to a robot?

Moderne wetenskap bevestig vandag wat filosowe vir eeue reeds verkondig, naamlik dat die wêreld 'daar buite' en die beelde wat ons in ons koppe daarvan ronddra, totaal verskillende werklikhede is. Hoe hulle verskil, is die reis waarop Maryna Blomerus haar lesers in Meer as 'n Metafoor wil neem.
Meer as 'n Metafoor ontsluit die diepte en krag van 'n heelal wat volgens die beginsels van selfverwysing en holisme, soos uitgelê deur Jan Smuts in Holism and Evolution, in beheer is van sy eie ewolusie, en redeneer dat die mens die kollektiewe oog is waarmee hierdie heelal homself ken, waarneem en voortdurend herskep.

Minerals are the building blocks of rocks - they make up the solid Earth's crust. Understanding Minerals & Crystals takes a close look at minerals, how they form, why they differ and how to go about identifying them. It begins by examining the nature of atoms and the way they bind together to form minerals with distinctive crystal structures; and it discusses the nature and classification of these crystals, and includes a mineral identification key. The second part of the book contains detailed descriptions of some 80 common and important minerals, including how they were named, their properties, ID pointers, uses and where in the world they are found. All are lavishly illustrated with full-colour photographs. This book will be invaluable to those interested in any of the earth sciences, or in mineral/crystal collecting - from academics and students to general enthusiasts.

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.

The Magaliesberg by Vincent Carruthers was first published in 1990. A second edition was published in 2000 and reprinted in 2007. It has now been revised again for publication to coincide with the international proclamation of the Magaliesberg Biosphere. The book has been highly successful and is a valuable source of information about the Magaliesberg, its geology, biodiversity and human history. During the decades since its publication substantial changes have taken place in in South Africa and in the Magaliesberg region and the revised editions to the book have taken cognisance of these. Most importantly, The Magaliesberg has had a profound influence on government and public awareness of the region and it has led directly to application to UNESCO for the Magaliesberg to be registered as a Biosphere Reserve in June 2014. This international recognition of the importance of the area will greatly enhance conservation efforts and stimulate tourism, education and research in the region. The current edition of the book celebrates this accomplishment and it will continue to be the primary source of information for public readership.

The Magaliesberg mountains are more than two billion years old - one of the oldest mountain ranges on the planet - and the book traces their creation and the changes in the landscape over this vast passage of time. The ancient geomorphology has given rise to a wide spectrum of different habitats and a consequent diversity of plant and animal life. The book's extensive descriptions of the fauna and flora of the area inspire the reader to consider the impact that man has on his environment. Each of the main plant and animal groups - trees, flowers, birds, mammals, reptiles and insects - has a full chapter devoted to it with checklists of every species found in the area indicating both the Scientific as well as common names.

The second half of the book is dedicated to the immensely rich human history of the Magaliesberg and is equally comprehensive. Starting with the pre-hominid ancestors of humankind it describes the paleontological and archaeological evidence of the succession of people who have lived in the mountains over hundreds of thousands of years. Stone Age tools and etchings, Iron Age walled villages as well as the forts and battlefields of more recent centuries are all brought to life in detailed accounts of the people and events of the time.

The prehistoric record of southern Africa extends back some 2 million years. The oldest cultural artefacts are stone tools such as handaxes, cleavers and choppers. In more recent centuries, archaeologists have found an extensive repertoire of artefacts including not only stone tools, but tools of bone, wood and shell as well as beads, jewellery, grinding stones, clothing, fishing equipment, burials and southern Africa's enigmatic rock art. Understanding these painted scenes and menageries is not immediately obvious. Using this interpretive guide, visitors to these ancient shrines can properly interpret rock art panels and make sense of the complex world of Bushman beliefs.
