'We have some wonderful mosaics in Pompeii, but I've never seen a better one than this!' After the young Roman mosaic designer Felix starts work in Pompeii, his whole life changes. There he falls in love with the beautiful Greek slave Agathe, who can see into the future. When the volcano Vesuvius sends hot ash over the city, Felix — and Agathe's brother Alcander — ride to the port of Misenum for help. But will they reach admiral Gaius Plinius in time, and will they ever see Agathe alive again?

Fearful of returning home to a violent father without having sold enough matches for the day, the Little Match Girl remains on the street resigned to warming herself by lighting matches. With each match, she sees a vision — a warm stove, a table laden with hot food, a beautiful Christmas tree decorated with lights leading up to the sky, so high that one becomes a shooting star. According to her grandmother, each shooting star is a person who had recently passed on and is now heading to heaven. Her next strike brings a vision of her grandmother — the only person in the world who ever loved the Little Match Girl — who takes her away in her warm embrace to heaven. The classic ending is intact here and accompanied by gentle, sensitive illustrations — children will return to this stirring tale often to understand its tragedy and the valuable lessons within.

'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.
