A groundbreaking exploration of the neuroscience of spirituality and a bold new paradigm for health, healing, and resilience.

Whether it's meditation or a walk in nature, reading a sacred text or saying a prayer, there are many ways to tap into a heightened awareness of the world around us and our place in it. Lisa Miller draws on decades of clinical experience and award-winning research to show that humans are universally equipped with this capacity for spirituality, and that our brains become more resilient and robust as a result of it. Bringing scientific rigour to the most intangible aspect of our lives, Miller's counterintuitive findings reveal the measurable positive effects of spirituality: for better decision-making, a healthier brain and an inspired life.

Brimming with inspiration and compassion, this landmark book revolutionizes our understanding of spirituality, mental health and how to find meaning and purpose in life.

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

Shall we take an umbrella... or evacuate the city? The Weather Machine is about a miraculous-but-overlooked invention that helps us through our daily lives - and sometimes saves them - by allowing us to see into the future.

When Superstorm Sandy hit North America, weather scientists had predicted its arrival a full eight days beforehand, saving countless lives and astonishing us with their capability. Their skill is unprecedented in human history and draws on nearly every major invention of the last two centuries: Newtonian physics, telecommunications, spaceflight and super-computing.

In this gripping investigation, Andrew Blum takes us on a global journey to explain this awe-inspiring feat - from satellites circling the Earth, to weather stations far out in the ocean, through some of the most ingenious minds and advanced algorithms at work today. Our destination: the simulated models they have constructed of our planet, which spin faster than time, turning chaos into prediction, offering glimpses of our future with eery precision.

This collaborative invention spans the Earth and relies on continuous co-operation between all nations - a triumph of human ingenuity and diplomacy we too often shrug off as a tool for choosing the right footwear each morning. But in this new era of extreme weather, we may come to rely on its maintenance and survival for our own.

‘We spend our whole lives in one body and yet most of us have practically no idea how it works and what goes on inside it. The idea of the book is simply to try to understand the extraordinary contraption that is us.’

Bill Bryson sets off 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 new book is an instant classic. It will have you marvelling at the form you occupy, and celebrating the genius of your existence, time and time again.

‘What I learned is that we are infinitely more complex and wondrous, and often more mysterious, than I had ever suspected. There really is no story more amazing than the story of us.’ Bill Bryson

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.

The text emphasises four themes to support evidence-based management decision making: 1. Setting the statistical landscape in a management context 2. Interpretative decision making based on patterns revealed by exploratory data analyses 3. Statistical decision making guided by the test-based findings of inferential analyses 4. Predictive decision making using statistical modelling evidence. The thread that links them is the role of data analytics as a management decision-support tool. This fifth edition builds on the strengths of the fourth edition by: - Highlighting newer trends in statistical applications in management practice - Strengthening the Excel-based generation of statistical evidence using a custom-built software product, called X-Static - Enhancing the graphic visualisation of statistical evidence. Target market: - Undergraduate students of Management at universities (BCom, BAcc, etc) - Management diploma students working towards professional qualifications at institutions such as the IMM, CSSA, CIMA, IAC, etc. - Postgraduate students (MBA and PGDip) of Management at business schools.

A Sunday Times and international bestseller, it is jam-packed with extraordinary facts, remarkable characters and astonishing stories.

The new 6th edition of Applied Combinatorics builds on the previous editions with more in depth analysis of computer systems in order to help develop proficiency in basic discrete math problem solving.

As one of the most widely used book in combinatorial problems, this edition explains how to reason and model combinatorically while stressing the systematic analysis of different possibilities, exploration of the logical structure of a problem, and ingenuity. Although important uses of combinatorics in computer science, operations research, and finite probability are mentioned, these applications are often used solely for motivation. Numerical examples involving the same concepts use more interesting settings such as poker probabilities or logical games.

This book is designed for use by students with a wide range of ability and maturity (sophomores through beginning graduate students). The stronger the students, the harder the exercises that can be assigned. The book can be used for one-quarter, two-quarter, or one-semester course depending on how much material is used.

Economic theories can be expressed in words, numbers, graphs and symbols. The existing traditional economics textbooks cover all four methods, but the general focus is often more on writing about the theory and methods, with few practical examples. With an increasing number of universities having introduced mathematical economics at undergraduate level, Basic mathematics for economics students aims to fill this gap in the field. Basic mathematics for economics students begins with a comprehensive chapter on basic mathematical concepts and methods (suitable for self-study, revision or tutorial purposes) to ensure that students have the necessary foundation. The book is written in an accessible style and is extremely practical. Numerous mathematical economics examples and exercises are provided as well as fully worked solutions using numbers, graphs and symbols. Basic mathematics for economics students is aimed at all economics students. It focuses on quantitative aspects and especially complements the three highly popular theoretical economics textbooks, Understanding microeconomics, Understanding macroeconomics and Economics for South African students, all written by Philip Mohr and published by Van Schaik Publishers.

Statistics and quantitative methods are brought to life for social science students in this tutorial course.

,P> This revised edition provides an overview of entry- and intermediate-level statistics, and the material on the accompanying website provides extensive practice. Both the text and the website are structured to make learning self-directed, thus numerous worked examples, exercises, activities and tests are included. The emphasis, throughout, is on practice.

Students are expected to engage with the material and experience multiple aspects of data and statistical analysis. Most of the tutorials include detailed examples of how to conduct analyses in Microsoft Excel, SPSS, or R.

The established text Statistics for Management and Economics delivers an accessible and comprehensive overview for business students across the UK, Europe, the Middle East and Africa. With a wealth of examples and real data, this statistics textbook is essential reading for all business, management and economics courses at undergraduate and MBA level.

Keller's practical three-step approach to problem-solving demonstrates how statistics are vital for today's managers and economists: it teaches students how to identify the correct technique for a problem or data type, compute the statistics and how to interpret the results meaningfully, equipping them with the practical skills they need in a world of big data, data visualization and social media.

Brilliant but overlooked ideas you must know, as revealed by today’s most innovative minds

What scientific term or concept ought to be more widely known? That is the question John Brockman, publisher of the acclaimed science salon Edge.org (“The world’s smartest website”—The Guardian), presented to 205 of the world’s most influential thinkers from across the intellectual spectrum—award-winning physicists, economists, psychologists, philosophers, novelists, artists, and more. From the origins of the universe to the order of everyday life, This Idea Is Brilliant takes readers on a tour of the bold, exciting, and underappreciated scientific concepts that will enrich every mind.

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.

The humble and industrious dung beetle is a marvellous beast: the 6 000 species identified so far are intricately entwined with human history and scientific endeavour.

These night-soil collectors of the planet have been worshipped as gods, worn as jewellery, and painted by artists. More practically, they saved Hawaii from ecological blight, and rescued Australia from plagues of flies. They fertilise soil, cleanse pastures, steer by the stars, and have a unique relationship with the African elephant (along with many other ungulates). Above all, they are the ideal subject for biological study in an evolving world.

In this sweeping history of more than 3 000 years, beginning with Ancient Egypt, scientist Marcus Byrne and writer, Helen Lunn capture the diversity of dung beetles and their unique behaviour patterns. Dung beetles’ fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy.

With over 6 000 species found throughout the world, these unassuming but remarkable creatures are fundamental to some of humanity’s most cherished beliefs and have been ever present in religion, art, literature, science and the environment. They are at the centre of current gene research, play an important role in keeping our planet healthy, and some nocturnal dung beetles have been found to navigate by the starry skies. Outlining the development of science from the point of view of the humble dung beetle is what makes this charming story of immense interest to general readers and entomologists alike. This entertaining outline of the development of science from the the beetle’s perspective will enchant general readers and entomologists alike.

Southern Africa has a particularly rich marine fauna and flora – almost 6% of all coastal marine species known worldwide occur here, along only 0.5% of the world’s coastline.
