The main aim of this book is to present a broader view of scientific software than has been common in the past. The provision of scientific software is no longer a matter of just writing 'good computer programs', but rather it is concerned with the development of an integrated software system wI-, ich offers the user facilities which approach all that he needs in terms of speed, accuracy and convenience. This means that due account must, for example, be taken of the high-speed computing capabilities of parallel processors, the exact computing features of symbolic mathematical systems, the presentational potentialities of computer graphics, and the advisory aspects of knowledge-based and expert systems. When suites of numerical software programs or routines are supported by such ranges of facilities, then they can be justly described as 'scientific software systems', and that is why we have adopted such a title here. The assembly of this book was a direct consequence of the running of a one-day international symposium, with the same broad aim of advocating a 'systems approach', under the title 'Scientific Software and Systems'. This Symposium was held at the Royal Military College of Science (RMCS) in Shrivenham on July 11, 1988 and was attended by 85 people. A very busy but most enjoyable day included invited talks, poster presentations and demonstrations of software products, not to mention various social activi ties."

Chebyshev polynomials crop up in virtually every area of numerical analysis, and they hold particular importance in recent advances in subjects such as orthogonal polynomials, polynomial approximation, numerical integration, and spectral methods. Yet no book dedicated to Chebyshev polynomials has been published since 1990, and even that work focused primarily on the theoretical aspects. A broad, up-to-date treatment is long overdue.

Providing highly readable exposition on the subject's state of the art, Chebyshev Polynomials is just such a treatment. It includes rigorous yet down-to-earth coverage of the theory along with an in-depth look at the properties of all four kinds of Chebyshev polynomials-properties that lead to a range of results in areas such as approximation, series expansions, interpolation, quadrature, and integral equations. Problems in each chapter, ranging in difficulty from elementary to quite advanced, reinforce the concepts and methods presented.

Far from being an esoteric subject, Chebyshev polynomials lead one on a journey through all areas of numerical analysis. This book is the ideal vehicle with which to begin this journey and one that will also serve as a standard reference for many years to come.

The influence of the Moravian Church on the missionary awakening in England and its contribution to the movement's nature and vitality. The Moravian Church became widely known and respected for its "missions to the heathen", achieving a high reputation among the pious and with government. This study looks at its connections with evangelical networks, and its indirect role in the great debate on the slave trade, as well as the operations of Moravian missionaries in the field. The Moravians' decision, in 1764, to expand and publicise their foreign missions (largely to the British colonies) coincided with the development of relations between their British leaders and evangelicals from various denominations, among whom were those who went on to found, in the last decade of the century, the major societies which were the cornerstone of the modern missionary movement. These men were profoundly influenced by the Moravian Church's apparent progress, unique among Protestants, in making "real" Christians among the heathen overseas, and this led to the adoption of Moravian missionary methods by the new societies. Dr Mason draws on a wide range of primary documents to demonstrate the influences of the Moravian Church on the missionary awakening in England and its contribution to the movement. Dr J.C.S. Mason first became aware of both the International Moravian Church (Unitas Fratrum) and his La Trobe forebears, who appear in the book, whilst working for his degree as a mature student at Birkbeck College, University of London; he later completed his thesis at King's College London.
