'What's your job?' Yukio asks. I'm a sorcerer, the old man smiles, 'and I need a young apprentice.' One day, Yukio — a young boy from old Japan — leaves his sister in the country and looks for a job in the town. He finds interesting work there, as a sorcerer's apprentice. But why must Yukio wait to learn magic? And what happens after he puts a spell on a broom when the sorcerer is away?

Film is considered by some to be the most dominant art form of the twentieth century. It is many things, but it has become above all a means of telling stories through images and sounds. The stories are often offered to us as quite false, frankly and beautifully fantastic, and they are sometimes insistently said to be true. But they are stories in both cases, and there are very few films, even in avant-garde art, that don't imply or quietly slip into narrative. This story element is important, and is closely connected with the simplest fact about moving pictures: they do move. Even the older meanings of the word 'film' — a membrane, a covering, a veil, an emanation — now seem to have something to do with moving pictures. Many people believe films are an instrument of illusion, an emphatic way of seeing what is not there; and this capacity has been both celebrated and condemned. 'Like a movie' mostly means like some sort of fairy-tale. But what about the reverse proposition: that more than any other invention film brings us close to the world as it actually is? 'Photography is truth', a character says in a film by Jean-Luc Godard. 'And cinema is the truth twenty-four times per second'. The same claim is made every day, albeit less epigrammatically, by newsreels and surveillance cameras. In this Very Short Introduction Michael Wood provides a brief history and examination of the nature of the medium of film, considering its role and impact on society as well as its future in the digital age.

Every atom of our bodies has been part of a star. Our very own star, the Sun, is crucial to the development and sustainability of life on Earth. This Very Short Introduction presents a modern, authoritative examination of how stars live, producing all the chemical elements beyond helium, and how they die, sometimes spectacularly, to end as remnants such as black holes. Andrew King shows how understanding the stars is key to understanding the galaxies they inhabit, and thus the history of our entire Universe, as well as the existence of planets like our own. King presents a fascinating exploration of the science of stars, from the mechanisms that allow stars to form and the processes that allow them to shine, as well as the results of their inevitable death.

Robotics is a key technology in the modern world. Robots are a well-established part of manufacturing and warehouse automation, assembling cars or washing machines, and, for example, moving goods to and from storage racks for Internet mail order. More recently robots have taken their first steps into homes and hospitals, and seen spectacular success in planetary exploration. Yet, despite these successes, robots have failed to live up to the predictions of the 1950s and 60s, when it was widely thought — by scientists and engineers as well as the public — that by turn of the 21st century we would have intelligent robots as butlers, companions, or co-workers. This Very Short Introduction explains how it is that robotics can be both a success story and a disappointment, how robots can be both ordinary and remarkable, and looks at their important developments in science and their applications to everyday life.

Plants form a fundamental element of the biosphere, and the evolution of plants has directly affected the evolution of animal life and the evolution of the Earth's climate. Plants have also become essential to humans not only in the form of cereal crops, fruit, and vegetables, but in their many other uses in wood and paper, and in providing medicines. Their aesthetic importance too in our parks and gardens as well as in wildflower meadows and great forests should not be underestimated. In this Very Short Introduction Timothy Walker, Director of the Botanical Gardens in Oxford, provides a concise account of the nature of plants, their variety, their evolution, and their importance and uses, stressing the need and efforts for their conservation for future generations.

Magnetism is a strange force, mysteriously attracting one object to another apparently through empty space. It has been claimed as a great healer, with magnetic therapies being proposed over the centuries and still popular today. Why are its mysterious important to solve? In this Very Short Introduction, Stephen J. Blundell explains why. For centuries magnetism has been used for various exploits; through compasses it gave us navigation and through motors, generators, and turbines it has given us power. Blundell explores our understanding of electricity and magnetism, from the work of Galvani, Ampere, Faraday, and Tesla, and goes on to explore how Maxwell and Faraday's work led to the unification of electricity and magnetism, thought of as one of the most imaginative developments in theoretical physics. With a discussion of the relationship between magnetism and relativity, quantum magnetism, and its impact on computers and information storage, Blundell shows how magnetism has changed our fundamental understanding of the Universe.

Mathematics is a fundamental human activity that can be practised and understood in a multitude of ways; indeed, mathematical ideas themselves are far from being fixed, but are adapted and changed by their passage across periods and cultures. In this Very Short Introduction, Jacqueline Stedall explores the rich historical and cultural diversity of mathematical endeavour from the distant past to the present day. Arranged thematically, to exemplify the varied contexts in which people have learned, used, and handed on mathematics, she also includes illustrative case studies drawn from a range of times and places, including early imperial China, the medieval Islamic world, and nineteenth-century Britain.

Engineering is part of almost everything we do — from the water we drink and the food we eat, to the buildings we live in and the roads and railways we travel on. In this Very Short Introduction, David Blockley explores the nature and practice of engineering, its history, its scope, and its relationship with art, craft, science, and technology. He considers the role of engineering in the modern world, demonstrating its need to provide both practical and socially acceptable solutions, and explores how engineers use natural phenomena to embrace human needs. From its early roots starting with Archimedes to some of the great figures of engineering such as Brunel and Marconi, right up to the modern day, he also looks at some of its challenges — when things go wrong — such as at Chernobyl. Ultimately, he shows how engineering is intimately part of who and what we are.

Civil engineering produces the structures of all human settlements worldwide and is a vital discipline for many aspects modern life, underlying housing, transport, and our major areas and buildings related to work, study, and leisure. In this Very Short Introduction, David Muir Wood demonstrates the nature and importance of civil engineering not only in the history of civilization and urbanization, but its range of facets today, and its challenges for the future. Beginning with the challenge of creating a settlement on a deserted island, which sets out the problems that civil engineers need to solve, he looks at the social and environmental considerations as well as the science, technology, and craft of building bridges, tunnels, houses, and areas of recreation. He highlights the lives of some major civil engineers, including Brunel and Bazalgette, considers the challenges of managing water and energy, and looks at our increasing sensitivity to building and the environment.

It is a striking aspect of contemporary western culture that, alongside a decline in traditional religious affiliations, there has been a growing interest in spirituality and the use of the word in a variety of contexts. Indeed, spirituality is sometimes contrasted favorably with religion, which many people see (for good or ill) as an off-putting amalgam of dogma, moralism, institutions, buildings, and hierarchies. This Very Short Introduction, written by one of the most eminent scholars and writers on spirituality, explores the historical foundations of spirituality and considers how it came to have the significance it has today. The notion of spirituality, Philip Sheldrake notes, expresses the fact that many people are driven by goals that concern more than material satisfaction. Broadly, it refers to the deepest values and sense of meaning by which people seek to live. Sometimes these values are conventionally religious. Sometimes they are associated with what is understood as the sacred in a broader sense — that is, of ultimate rather than merely instrumental importance. Looking at spirituality in religion, philosophy, anthropology, and psychology, Sheldrake sheds light on the concept of the spiritual experience and considers the impact and transformation it can have on individuals and on society.

China's decade-long Great Proletarian Cultural Revolution shook the politics of China and the world. Even as we approach its fiftieth anniversary, the movement remains so contentious that the Chinese Communist Party still forbids fully open investigation of its origins, development, and conclusion. Drawing upon a vital trove of scholarship, memoirs, and popular culture, this Very Short Introduction illuminates this complex, often obscure, and still controversial movement. Moving beyond the figure of Mao Zedong, Richard Curt Kraus links Beijing's elite politics to broader aspects of society and culture, highlighting many changes in daily life, employment, and the economy. Kraus also situates this very nationalist outburst of Chinese radicalism within a global context, showing that the Cultural Revolution was mirrored in the radical youth movement that swept much of the world, and that had imagined or emotional links to China's red guards. Yet it was also during the Cultural Revolution that China and the United States tempered their long hostility, one of the innovations in this period that sowed the seeds for China's subsequent decades of spectacular economic growth.

Defining 'magic' is a maddening task. Over the last century numerous philosophers, anthropologists, historians, and theologians have attempted to pin down its essential meaning, sometimes analysing it in such complex and abstruse depth that it all but loses its sense altogether. For this reason, many people often shy away from providing a detailed definition, assuming it is generally understood as the human control of supernatural forces. 'Magic' continues to pervade the popular imagination and idiom. People feel comfortable with its contemporary multiple meanings, unaware of the controversy, conflict, and debate its definition has caused over two and a half millennia. In common usage today 'magic' is uttered in reference to the supernatural, superstition, illusion, trickery, religious miracles, fantasies, and as a simple superlative. The literary confection known as 'magical realism' has considerable appeal and many modern scientists have ironically incorporated the word into their vocabulary, with their magic acid, magic bullets and magic angles. Since the so-called European Enlightenment magic has often been seen as a marker of primitivism, of a benighted earlier stage of human development. Yet across the modern globalized world hundreds of millions continue to resort to magic — and also to fear it. Magic provides explanations and remedies for those living in extreme poverty and without access to alternatives. In the industrial West, with its state welfare systems, religious fundamentalists decry the continued moral threat posed by magic. Under the guise of neo-Paganism, its practice has become a religion in itself. Magic continues to be a truly global issue. This Very Short Introduction does not attempt to provide a concluding definition of magic: it is beyond simple definition. Instead it explores the many ways in which magic, as an idea and a practice, has been understood and employed over the millennia.

Throughout history plague has been the cause of many major catastrophes. It was responsible for the Black Death of 1348 and the Great Plague of London in 1665, and for devastating epidemics much earlier and much later, in the Mediterranean in the sixth century, and in China and India between the 1890s and 1920s. Today, it has become a metaphor for other epidemic disasters which appear to threaten us, but plague itself has never been eradicated. In this Very Short Introduction, Paul Slack explores the historical impact of plague over the centuries, looking at the ways in which it has been interpreted, and the powerful images it has left behind in art and literature. Examining what plague meant for those who suffered from it, and how governments began to fight against it, he demonstrates the impact plague has had on modern notions of public health and how it has shaped our history.

The rise and fall of the Roman Republic occupies a special place in the history of Western civilization. From humble beginnings on the seven hills beside the Tiber, the city of Rome grew to dominate the ancient Mediterranean. Led by her senatorial aristocracy, Republican armies defeated Carthage and the successor kingdoms of Alexander the Great, and brought the surrounding peoples to east and west into the Roman sphere. In this Very Short Introduction, David M. Gwynn provides a fascinating introduction to the history of the Roman Republic, ranging from the origins of Rome and the vivid Roman legends that surround the foundations of the city, to the overthrow of the monarchy in 509 BC, the five hundred years of republican rule, the rise of Julius Caesar and Caesar Augustus, and the establishment of the Principate. Gwynn considers the political structure of the Republic, including its unique constitution, and he highlights literary and material sources, bringing to life the culture and society of Republican Rome. He also reflects on the Roman values and beliefs of the time, in order to shed light on the Republic's dramatic rise and fall. Finally, Gwynn reflects on the remarkable legacy of the Roman Republic, including its modern-day resonance and legacy in literature and in film, where it is often presented as a model, a source of inspiration, but also a warning.

Metaphysics is one of the traditional four main branches of philosophy, alongside ethics, logic and epistemology. It is also an area that continues to attract and hold a fascination for many people yet it is associated with being complex and abstract. For some it is associated with the mystical or religious. For others it is known through the metaphysical poets who talk of love and spirituality. This Very Short Introduction goes right to the heart of the matter, getting to the basic and most important questions of metaphysical thought in order to understand the theory: What are objects? Do colours and shapes have some form of existence? What is it for one thing to cause another rather than just being associated with it? What is possible? Does time pass? By using these questions to initiate thought about the basic issues around substance, properties, changes, causes, possibilities, time, personal identity, nothingness and emergentism, Stephen Mumford provides a clear and simple path through this analytical tradition at the core of philosophical thought.

What is real? has been one of the key questions of philosophy since its beginning in antiquity. It is a question that, due to such films as The Matrix, has also made its way into popular culture. But it is not just a question philosophers ask. It is also asked by scientists when they investigate whether the fundamental constituents of matter are actually 'out there' or just a mere abstraction from a successful theory. Cognitive scientists ask it when trying to find out which set of the bewildering array of data processed by our brain could constitute the basis for such supposedly fundamental entities like the free agent or the self. This Very Short Introduction discusses what reality is by looking at a variety of arguments, theories and thought-experiments from philosophy, physics, and cognitive science.

Trust is indispensable, yet it can be dangerous. Without trusting others, we cannot function in society, or even stay alive for very long, but being overly-trustful can be a bad strategy too. Trust is pragmatic, but it also has a moral dimension: trustworthiness is a virtue, and well-placed trust benefits us all. In this Very Short Introduction, Katherine Hawley explores the key ideas about trust and distrust. Considerings questions such as 'Why do we value trust?' and Why do we want to be trusted rather than distrusted?, Hawley raises issues about the importance of trust in both the personal and public spheres, including family and relationships as well as politics and society.

Compelling and accessible, this Very Short Introduction challenges the perception of borders as passive lines on a map, revealing them instead to be integral forces in the economic, social, political, and environmental processes that shape our lives. Highlighting the historical development and continued relevance of borders, Alexander C. Diener and Joshua Hagen offer a powerful counterpoint to the idea of an imminent borderless world, underscoring the impact borders have on a range of issues, such as economic development, inter and intra-state conflict, global terrorism, migration, nationalism, international law, environmental sustainability, and natural resource management. Diener and Hagen demonstrate how and why borders have been, are currently, and will undoubtedly remain hot topics across the social sciences and in the global headlines for years to come.

Miss Cluck has some exciting news for her class. There is going to be an end-of-term show! All the animals rehearse tirelessly and soon the day of the show arrives. But then — disaster! — Miss Webb and her nursery class who should be coming to watch the show are stuck in the mud. How will the show go on? Boris has an idea. He dashes out (in his superhero costume), finds the stricken tractor, and heaves Miss Webb and her class out of the mud. With the tractor back on track, and Boris squeezed onto the trailer with the ducklings and frogs, Miss Webb makes it to Miss Cluck's class after all and the curtain rises on a wonderfully entertaining show. And, of course, Boris is the hero of the story, both on and off the stage!
