Astronomy, perhaps the first of the sciences, was already well developed by the time of Christ. Seventeen centuries later, after Newton showed that the movements of the planets could be explained in terms of gravitation, it became the paradigm for the mathematical sciences. In the nineteenth century the analysis of star-light allowed astrophysicists to determine both the chemical composition and the radial velocities of celestial bodies, while the development of photography enabled distant objects invisible to the human eye, to be studied and measured in comfort. Technical developments during and since the Second World War have greatly enlarged the scope of the science by permitting the study of radiation. This is a fascinating introduction to the history of Western astronomy, from prehistoric times to the origins of astrophysics in the mid-nineteenth century. Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam, and led to Copernicus's claim that the Earth is in motion. In justifying this Kepler converted astronomy into a branch of dynamics, leading to Newton's universal law of gravity. The book concludes with eighteenth- and nineteenth-century applications of Newton's law, and the first explorations of the universe of stars.

This text helps teachers to assess children's progress in English in a way that is appropriate for young learners. It offers jargon-free and practical advice, showing that assessment can be fun and motivating by integrating assessment into teaching, thus helping teachers to plan future lessons and revision. The book includes portfolios and preparation for the UCLES Young Learners tests.

A little mermaid saved a young prince from the stormy sea. His eyes were closed but he was alive. She left him on a beach and a young girl and her friends found him there. Nobody saw the little mermaid who went back to the sea. The little mermaid wanted legs. The sea witch wanted the little mermaid's beautiful voice. So the witch gave the little mermaid a magic drink, and cut off her tongue. The little mermaid swam up by the Prince's palace and drank the drink. The Prince liked this strange girl and she went everywhere with him. But the Prince only loved one girl - the girl who saved him from the stormy sea. The little mermaid wanted to say, 'That girl was me.' But she had no voice. When the Prince found that girl, the little mermaid's heart broke.

The massive disorder and economic ruin following the Second World War inevitably predetermined the scope and intensity of the Cold War. But why did it last so long? And what impact did it have on the United States, the Soviet Union, Europe, and the Third World? Finally, how did it affect the broader history of the second half of the twentieth century--what were the human and financial costs? This Very Short Introduction provides a clear and stimulating interpretive overview of the Cold War, one that will both invite debate and encourage deeper investigation.

The processes in a single living cell are akin to that of a city teeming with molecular inhabitants that move, communicate, cooperate, and compete. In this Very Short Introduction, Philip Ball explores the role of the molecule in and around us - how, for example, a single fertilized egg can grow into a multi-celled Mozart, what makes spider's silk insoluble in the morning dew, and how this molecular dynamism is being captured in the laboratory, promising to reinvent chemistry as the central creative science of the century.

For generations, the ground beneath the feet of our ancestors seemed solid and unchanging. Around 30 years ago, two things happened that were to revolutionize the understanding of our home planet. First, geologists realized that the continents themselves were drifting across the surface of the globe and that oceans were being created and destroyed. Secondly, pictures of the entire planet were returned from space. As the astronomer Fred Hoyle had predicted, this 'let loose an idea as powerful as any in history'. Suddenly, the Earth began to be viewed as a single entity; a dynamic, interacting whole, controlled by complex processes we scarcely understood. It began to seem less solid. As one astronaut put it, 'a blue jewel on black velvet; small, fragile and touchingly alone'. Geologists at last were able to see the whole as well as the detail; the wood as well as the trees. This book brings their account up to date with the latest understanding of the processes that govern our planet.
