Social mobility, educational priority areas and equality of opportunity are topics discussed as much today as when this book was first published over 30 years ago. This book is written by people of varying ages and professions who have broken through from poor social beginnings, deprived backgrounds and many disadvantages into a high level of professional achievement. Starting in working class or slum environments in areas such as Sheffield, Wales, Manchester, Leeds, Huddersfield, London, Glasgow and Birmingham they describe their struggles and the ways in which they attempted to over-come their earlier deprivations. The descriptions in this volume are illustrations of potential which is present in the most unpromising beginnings.

Amid recent interest in Clifford algebra for dual quaternions as a more suitable method for Computer Graphics than standard matrix algebra, this book presents dual quaternions and their associated Clifford algebras in a new light, accessible to and geared towards the Computer Graphics community. Collating all the associated formulas and theorems in one place, this book provides an extensive and rigorous treatment of dual quaternions, as well as showing how two models of Clifford algebras emerge naturally from the theory of dual quaternions. Each chapter comes complete with a set of exercises to help readers sharpen and practice their knowledge. This book is accessible to anyone with a basic knowledge of quaternion algebra and is of particular use to forward-thinking members of the Computer Graphics community. .

In this study, first published in 1965, the author explores the implications of research for an alternative approach to religious education. The book deals with the psychological bases of religious development, reviewing the natural limitations as well as the basic needs of the young, and how religious education should be affected by educational theory and practice. The author also examines what content and methods of teaching are consistent with the healthy development of children and adolescents. Teachers in schools, students in training, lecturers, clergy and ministers, and local education authority committees will welcome the book as an important aid to the task of rethinking syllabuses and the need for more child-centred methods of teaching.

Taking a novel, more appealing approach than current texts, An Integrated Introduction to Computer Graphics and Geometric Modeling focuses on graphics, modeling, and mathematical methods, including ray tracing, polygon shading, radiosity, fractals, freeform curves and surfaces, vector methods, and transformation techniques. The author begins with fractals, rather than the typical line-drawing algorithms found in many standard texts. He also brings the turtle back from obscurity to introduce several major concepts in computer graphics. Supplying the mathematical foundations, the book covers linear algebra topics, such as vector geometry and algebra, affine and projective spaces, affine maps, projective transformations, matrices, and quaternions. The main graphics areas explored include reflection and refraction, recursive ray tracing, radiosity, illumination models, polygon shading, and hidden surface procedures. The book also discusses geometric modeling, including planes, polygons, spheres, quadrics, algebraic and parametric curves and surfaces, constructive solid geometry, boundary files, octrees, interpolation, approximation, Bezier and B-spline methods, fractal algorithms, and subdivision techniques. Making the material accessible and relevant for years to come, the text avoids descriptions of current graphics hardware and special programming languages. Instead, it presents graphics algorithms based on well-established physical models of light and cogent mathematical methods.

First published in 1969, Angry Adolescents is the story of unruly adolescents and of how a Youth Club with such an unpromising membership developed in a village in the Home Counties, some forty miles from London, just outside normal commuter territory. The book intends to fill an academic gap in adolescent literature by providing case studies of individual adolescents from difficult home backgrounds and how they behaved in a certain situation in the years of the mid-sixties. The first section of the book provides a description of how young people work and spend their leisure, along with a sociological assessment of the district. It is followed by a discussion on the birth and the development of the youth club. The remaining sections deal with varying behaviour patterns in relation to money, sex, employment and other aspects. The book has been made readable to the general reader who is interested in young people, not only to those engaged in youth work, without compromising on any aspect of educational psychology.

First published in 1964, Religious Thinking from Childhood to Adolescence describes the capacities of pupils of varying ages, abilities and backgrounds to understand religious truths. How concepts of the Bible, of God, of Jesus, of Prayer and of the Church developed from the early years is seen within the psychological context of maturing thought, and the implications for religious education, which are provocative and far-reaching, are explored. Teachers, clergy and parents will find this book a challenge to reconsider not only how the growing child views what he is taught but also the reasons why he frequently misunderstands religious teaching. By presenting a systematic account of religious thinking from 6 to 17 years, Dr. Goldman adds a new dimension to our insights into child development.
