Surveying key developments and open issues in cosmology for graduate students and researchers, this book focuses on the general concepts and relations that underpin the standard model of the Universe. It also examines anisotropic and inhomogeneous models, and deeper issues, such as quantum cosmology and the multiverse proposal.
Traces the ownership of the Bell Ranch, beginning in the early 1800s with Pablo Montoya, who was first granted title by the Mexican government to the 655,468 acres comprising the original ranch, to 1973. George Ellis managed the Bell Ranch for almost a quarter century and was one of but six men who served as general manager in its 150-year history. Donald Ornduff, well known cattle editor, writer and researcher sets the historical stage for the story, and Robert Lougheed provides the illustrations.
A detailed overview of the physics of high-energy colliders emphasising the role of QCD.
This title will help engineers to apply control theory to practical systems using their PC. It provides an intuitive approach to controls, avoiding unecessary math and emphasising key concepts with control system models
Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a 'black hole' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an ...
This is a practical approach to control techniques. The author covers background material on analog controllers, digital controllers, and filters. Commonly used controllers are presented. Extended use of PSpice (a popular circuit simulation program) is used in problem solving. The book is also documented with 50 computer programs that circuit designers can use. - Explains integration of control systems with a personal computer - Compares numerous control algorithms in digital and analog form - Details the use of SPICE in problem solving - Presents modeling concepts for linear and nonlinear systems - Examines commonly used controllers
First published in 1973, this influential work discusses Einstein's General Theory of Relativity to show how two of its predictions arise: first, that the ultimate fate of many massive stars is to undergo gravitational collapse to form 'black holes'; and second, that there was a singularity in the past at the beginning of the universe. Starting with a precise formulation of the theory, including the necessary differential geometry, the authors discuss the significance of space-time curvature and examine the properties of a number of exact solutions of Einstein's field equations. They develop the theory of the causal structure of a general space-time, and use it to prove a number of theorems establishing the inevitability of singularities under certain conditions. A Foreword contributed by Abhay Ashtekar and a new Preface from George Ellis help put the volume into context of the developments in the field over the past fifty years.
The first edition of A Symphony of Silence: An Enlightened Vision was inspired by the desire to share with humanity, through multiple voices, the ineffable beauty we experience in our lives when the veil of ignorance is pulled back and the wonder of our essential nature is revealed.. The voices emerging from these pages add vitality and validity to our shared experience of the silence of the transcendent. It is not something beyond our reach, but a reality that has always been with us, quietly awaiting an opportunity to unfold. In this second edition of A Symphony of Silence, several new voices are added to the chorus of the first edition. A Catholic priest tells us of using TM as part of hi...
Ellis O. Briggs (1899-1976) entered the Foreign Service of the United States in 1925. During the next 37 years, he was ambassador to seven countries. He also served in Cuba, Chile, Liberia, and China. This is a collected volume of his memoirs.
A thought-provoking, original appraisal of the meaning of religion by the host of public radio's On Being Krista Tippett, widely becoming known as the Bill Moyers of radio, is one of the country's most intelligent and insightful commentators on religion, ethics, and the human spirit. With this book, she draws on her own life story and her intimate conversations with both ordinary and famous figures, including Elie Wiesel, Karen Armstrong, and Thich Nhat Hanh, to explore complex subjects like science, love, virtue, and violence within the context of spirituality and everyday life. Her way of speaking about the mysteries of life-and of listening with care to those who endeavor to understand those mysteries--is nothing short of revolutionary.
