Between Planets

The message had seemed simple, yet it was more complex than Don could have imagined. He was being called from Earth to an alien world for reasons unknown¾save only that his life depended on it. But setting out for Mars and getting there in good shape turned out to be a lot more complicated than Don ever would have guessed possible. It was trouble enough being inexplicably hounded by Earth's secret police. But when he was hijacked by Venusian rebels, Don suddenly realized that he was trapped in the center of a war between worlds that could change the fate of the Solar System forever!

The book begins with a historical review of four major theories for the origin of the Solar System in particular, or of planets in general, which highlight the major problems that need to be solved by any plausible theory. In many theories, including that which form the major theme of this book, the formation of planets and stars is intimately linked, so four chapters are devoted to the processes that can be described as the birth, life and death of stars. Recent observations that have revealed the existence of planets around many Sun-like stars are described in detail, followed by a clear exposition of the Capture Theory for the origin of planets. Many aspects of this theory are illustrated with sophisticated computer modelling that convincingly demonstrates the plausibility of the theory. The Capture Theory is in complete accord with all observations, including the estimate it gives for the proportion of Sun-like stars with planets. It is the only theory that sits comfortably with all present observational and theoretical constraints. The general theory of planet formation does not explain the detailed structure of the Solar System. An early postulated collision of two major planets is shown to explain many disparate features of the Solar System the nature of the terrestrial planets, surface features of the Moon and its relationship with Earth, asteroids, comets and dwarf planets, the relationship between Neptune, Triton and Pluto and the characteristics of meteorites, including the isotopic anomalies found in them. The postulate of a planetary collision is given support by a 2009 NASA observation of the residue of such an event around a distant young star.

Keywords:Planets: Solar SystemKey Features:There are no competing titlesThe structure of the book, with main chapters and appendices, should make it accessible and of interest to readers of different backgroundsThe theory it deals with is described in fine detail — a model of presentation inspired by On The Origin of SpeciesReviews:“The first quarter of the presentation is a masterful summary of the history of the speculation about the origin of the sun and planets, a description of the properties of stars and star clusters, and an introduction to the exciting and developing field of exoplanets, objects that orbit distant stars … The presentation is primarily qualitative, with the supporting physical principles usefully relegated to an extensive suite of appendixes … the level is suitable for the advanced undergraduate.”CHOICE “This book describes the history and the problem of planetary formation question in more complete and attractive detail. In an unusual but excellent feature, the basic physics needed at each stage is broken out into a long series of appendices, 39 in all.”Contemporary Physics

An Astrological Comparison Of Planets In Medical Diagnosis, is the first volume in a series connecting the natal chart of the individual with the potential for illness. Using the indicators in the book, the professional astrologer and those interested in health may be able to improve their health and the health of their clients, by referring them to healthcare professionals in a timely manner. This book could be used to help healthcare professionals in treating their clients in a timely manner, and allow the client the ability to understand how stress factors in their charts are contributing to their health. Changing those factors, or the response to those factors allows the client control of their own destiny. In some cases hereditary factors are prominent, and looking in the past at family members and manifestations of stress factors can shed some light on how this will manifest for the client. This book is one of the few astrological works dedicated to astrological health. All of the examples cited in this work are real cases with real outcomes. This book would be a great addition to any library, any personal collection, and a teaching tool for the astrological student or healthcare professional. This book would do well over the Internet; many of the clients asking about the book and when it will come out are Internet users. It would also do well as an addition to any library, or new age book store. This book on the arterial system, is the first volume in a series pertaining to health care and the natal chart. The second volume will comprise the gastric system and traumas, and the third volume will comprise leukemias of various forms. These works will add to the great knowledge of astrology and its connection to mankind allowing the expansion of ones knowledge base to a higher level.

This book explores the dynamics of planetary and stellar fluid layers, including atmospheres, oceans, iron cores, and convective and radiative zones in stars, describing the different theoretical, computational and experimental methods used to study these problems in fluid mechanics, including the advantages and limitations of each method for different problems. This scientific domain is by nature interdisciplinary and multi-method, but while much effort has been devoted to solving open questions within the various fields of mechanics, applied mathematics, physics, earth sciences and astrophysics, and while much progress has been made within each domain using theoretical, numerical and experimental approaches, cross-fertilizations have remained marginal. Going beyond the state of the art, the book provides readers with a global introduction and an up-to-date overview of relevant studies, fully addressing the wide range of disciplines and methods involved. The content builds on the CISM course “Fluid mechanics of planets and stars”, held in April 2018, which was part of the research project FLUDYCO, supported by the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program.

Publisher description

This richly illustrated book contains over 200 photographs, nearly half of which are in full colour. It constitutes the best collection of available photographs of the planets that have been obtained from space over the past two decades. Also included, wherever available, are global maps of the planets and their satellites. Each of the following chapters is devoted to one of the planets, summarizing what has been learned about that planet and explaining in non-technical terms the features that can be seen in the many breathtaking photographs that are presented. The chapters are set out with the text first, followed by the figures, each accompanied by a long caption describing its essential points.
