Sommario/riassunto

Since first Thomas Aquinas defined theology as revelation, or the rational elucidation of revealed truth, the idea of revelation has played a fundamental role in the history of western theology. This book provides a new and detailed investigation of the concept, examining its nature, sources, and limitations in all five of the major scriptural religions of the world: Christianity, Judaism, Islam, Hinduism, and Buddhism.; The first part of the book discusses the nature of theology, and expounds the comparative method as the most useful and appropriate for the modern age. Part Two focuses on the nature of religion and its early historical manifestations, whilst the third part of the book goes on to consider the idea of revelation as found in the great canonical traditions of the religions of the world. Part Four develops the distinctively Christian idea of revelation as divine self-expression in history. The final part of the book discusses how far the idea of revelation must be revised or adapted in the light of modern historical and scientific thought, and proposes a new and positive theology of revelation for the future. The book includes discussions of



the work of most major theologians and scholars in the study of religion - Aquinas, Tillich, Barth, Temple, Frazer, and Evans Pritchard - and should be of interest to many scholars and students of comparative religion and theology, and anthropologists.

Sommario/riassunto

With space-industry professionals and university students, this book offers a practical technical reference for seeking to understand the state of the art in spacecraft momentum control systems. The focus is control moment gyroscope (CMG) technology, but general principles of momentum control—for example, through reaction wheels, magnetic torque actuation, and other means—are presented. These key topics are treated in several contexts: systems engineering and spacecraft architecture, attitude control and dynamics, and mission operations. The subject matter is developed with theoretical rigor and in terms of practical implementation in flight hardware software. This book is the first to address CMG technology in depth, let alone from a practitioner’s perspective. It is also timely, given the rise of commercial Earth imaging, the imminent need for high-torque manipulation of satellites for servicing and assembly, the advances in privately built spacecraft (including small satellites), and the growing popularity of the subject matter in academia over the past two decades. The current edition includes exercises suitable for upper-level undergraduate courses and graduate-level courses in spacecraft attitude dynamics and control, spacecraft design, and space systems engineering. This second edition provides more applications, attitude control, momentum and nutation dumping, isolation, system identification, systems engineering, bearings, and structures as well as more in depth discussions of equations of motion, as well as the numerics and complexity associated with generalized inverses that are used for steering algorithms.
