The Holographic Universe

An Introduction to Black Holes, Information and the String Theory Revolution

' Over the last decade the physics of black holes has been revolutionized by developments that grew out of Jacob Bekenstein's realization that black holes have entropy. Stephen Hawking raised profound issues concerning the loss of information in black hole evaporation and the consistency of quantum mechanics in a world with gravity. For two decades these questions puzzled theoretical physicists and eventually led to a revolution in the way we think about space, time, matter and information. This revolution has culminated in a remarkable principle called “The Holographic Principle”, which is now a major focus of attention in gravitational research, quantum field theory and elementary particle physics. Leonard Susskind, one of the co-inventors of the Holographic Principle as well as one of the founders of String theory, develops and explains these concepts.

This is impressive, given that the authors cover some of the hottest topics in current research … conceptually the book is truly challenging. It makes us think about many ideas we take for granted and shakes the foundations of our understanding of basic physics. It provides a rollercoaster ride into the treacherous and largely uncharted land of quantum gravity. This book is highly recommended for those interested in these fascinating topics.”CERN Courier “Students and non-specialists will welcome this book, which provides an entry into this fascinating realm at a level that can be enjoyed by an enterprising undergraduate … This well-planned, stimulating and sometimes provocative book can be enthusiastically recommended.”Classical and Quantum Gravity “The authors, both established researchers, present a review of black hole physics in one of the simplest and most efficient ways … The book will be useful for students of physics and for everyone interested in understanding ways in which knowledge is generated theoretically.”Mathematical Reviews '

Delirium is a cognitive disorder consisting of deficits of attention, arousal, consciousness, memory, orientation, perception, speech and language. It represents the most frequent complication of hospitalisation in the older population. Despite its importance in terms of clinical, economic and social considerations, and despite considerable advances in the past decade, it remains a relatively misunderstood and mis-diagnosed condition. This book provides a state-of-the-art update of delirium research, covering its history, conceptualisation, measurement, epidemiology, pathophysiology, assessment, diagnosis, causes, prevention and management. The final chapter takes a look to the future, highlighting the importance of ongoing interdisciplinary research. As well as being important as a clinical syndrome in its own right, the study of delirium provides a valuable opportunity to understand brain functioning at a fundamental level, and as it is a preventable condition, it is also now being used as a marker to measure the quality of hospital care provided for older people. This volume will serve as a catalyst to revive interest and progress in delirium research and clinical care, and should be read by psychiatrists, neurologists, geriatricians and all those involved in working with the elderly in hospitals or in the community.

Delirium in Old Age

Ian Starke

This book provides a comprehensive, scholarly, and practical account of delirium for all doctors involved in the care of the elderly. Delirium is defined as an acute or subacute non-specific response of the brain to a wide variety of physical and psychological causes that are nearly always treatable. However, problems arise if the underlying trauma is not identified and corrected, or if the delirious state itself is badly managed or misdiagnosed. In some cases, elderly people may be rendered delirious by their own doctors through haphazard prescribing, inappropriate admission to the hospital, or as a result of surgery. Since our population is aging, the proper identification, assessment, management, and prevention of delirium is essential for the efficient use of health resources. This book will be an invaluable sourcebook for psychologists, gerontologists, psychiatrists, and physicians.

Delirium in the Elderly

Delirium is a cognitive disorder consisting of deficits of attention, arousal, consciousness, memory, orientation, perception, speech and language. It is a prevalent, although relatively misunderstood and often mis-diagnosed, disorder of old age. This book provides a comprehensive, critical overview of the current state of international delirium theory and research.

Ein Delir stellt die häufigste Komplikation bei hospitalisierten alten Menschen dar. Trotz seiner klinischen, sozialen und ökonomischen Folgen wird das Phänomen von vielen Praktikern noch nicht verstanden oder oft fehldiagnostiziert. Menschen, die ein Delir erleiden, sind massiv beeinträchtigt in ihrer Kognition, Aufmerksamkeit, Orientierung, Wachheit, Wahrnehmung, Sprache und Kommunikation sowie in ihrem Bewusstsein und Gedächtnis. Das evidenzbasierte Handbuch der britischen Autoren stellt die aktuelle Forschung, Konzepte, Pathophysiologie, Messinstrumente, Epidemiologie, Assessments, Diagnostik, Prävention und Behandlung eines Delirs dar. Das Phänomen "Delir" zu verstehen bedeutet auch, das Gehirn und seine Funktionsweise besser zu verstehen. Es ist ein wichtiger Indikator für die Qualität der Krankenhausversorgung. Aus dem Inhalt: - Konzept, Epidemiologie und Neurophysiologie des Delirs - Assessment, Ätiologie und Diagnose - Management und Prävention des Delirs - Die Bedeutung von Familien, Angehörigen und Pflegenden - Fort- und Weiterbildung zum Thema Delir.

Praxishandbuch für Pflegende und Mediziner

Akute Verwirrtheit - Delir im Alter

Exploring how the subtleties of quantum coherence can be consistently incorporated into Einstein's theory of gravitation, this book is ideal for researchers interested in the foundations of relativity and quantum physics. The book examines those properties of coherent gravitating systems that are most closely connected to experimental observations. Examples of consistent co-gravitating quantum systems whose overall effects upon the geometry are independent of the coherence state of each constituent are provided, and the properties of the trapping regions of non-singular black objects, black holes and a dynamic de Sitter cosmology are discussed analytically, numerically and diagrammatically. The extensive use of diagrams to summarise the results of the mathematics enables readers to bypass the need for a detailed understanding of the steps involved. Assuming some knowledge of quantum physics and relativity, the book provides text boxes featuring supplementary information for readers particularly interested in the philosophy and foundations of the physics.
