If standard gravitational theory is correct, then most of the matter in the universe is in an unidentified form which does not emit enough light to have been detected by current instrumentation. This book is the second editon of the lectures given at the 4th Jerusalem Winter School for Theoretical Physics, with new material added. The lectures are devoted to the "missing matter" problem in the universe, the search to understand dark matter. The goal of this volume is to make current research work on unseen matter accessible to students without prior experience in this area and to provide insights for experts in related research fields. Due to the pedagogical nature of the original lectures and the intense discussions between the lecturers and the students, the written lectures included in this volume often contain techniques and explanations not found in more formal journal publications. more...

A lively astronomy primer that uses cataclysmic scenarios to explain the universe’s most fascinating events. According to astronomer Philip Plait, the universe is an apocalypse waiting to happen But how much do we really need to fear from things like black holes, gamma-ray bursts, and supernovae? And if we should be scared, is there anything we can do to save ourselves? With humor and wit, Plait details the myriad doomsday events that the cosmos could send our way to destroy our planet and life as we know it. This authoritative yet accessible study is the ultimate astronomy lesson. Combining fascinating—and often alarming—scenarios that seem plucked from science fiction with the latest research and opinions, Plait illustrates why outer space is not as remote as most people think. Each chapter explores a different phenomenon, explaining it in easy-to-understand terms, and considering how life on earth and the planet itself would be affected should the event come to pass. Rather than sensationalizing the information, Plait analyzes the probability of these catastrophes occurring in our lifetimes and what we can do to stop them. With its entertaining tone and enlightening explanation of unfathomable concepts, Death from the Skies! will appeal to science buffs and beginners alike. more...

Deconditioning is an integrated physiological response of the body to a reduction in metabolic rate, that is, to a reduction in energy use or in exercise level. This multi-author volume presents selected background information on the many aspects of ground-based and inflight physiological research and applications and will be of special interest to health professionals and clinical physicians. The emphasis is on human research programmes on prolonged bed rest, immersion and confinement studies simulating conditions of space flight as well as data from humans in space. more...

The phenomena observed in young stellar objects (YSO), circumstellar regions and extra-galactic nuclei show some similarity in their morphology, dynamical and physical processes, though they may differ in scale and energy. The European Workshop on Astronomical Molecules 2004 gave astronomers a unique opportunity to discuss the links among the observational results and to generate common interpretations of the phenomena in stars and galaxies, using the available diagnostic tools such as masers and dense molecular gas. Their theoretical understanding involves physics, numerical simulations and chemistry. Including a dozen introductory reviews, topics of papers in this book also cover: maser and dense gas diagnostics and related phenomena, evolution of circumstellar regions around protostars, evolution of circumnuclear regions of active galaxies, diagnostics of the circumnuclear gas in stars and galactic nuclei. This book summarizes our present knowledge in these topics, highlights major problems to be addressed, and finally proposes future work. more...
