Above Misminay, the sky also is so divided by the alternation of the two axes of the Milky Way passing through the zenith. This mirror-image quadri-partition of terrestrial and celestial spheres is such that a point within one of the quarters of the earth is related to a point within the corresponding celestial quarter. The transition between the earth and the sky occurs at the horizon, where sacred mountains are related to topographic and celestial features. Based on fieldwork in Misminay, Peru, Gary Urton details a cosmology in which the Milky Way is central. This is the first study that provides a description and analysis of the astronomical and cosmological system in a contemporary community in the Americas. Separate chapters take up the sun, the moon, meteorological phenomena, the stars, and the planets. Star-to-star constellations, the "animal" dark-cloud constellations that cut through the Milky Way, and certain twilight- and midnight-zenith stars are analyzed in terms of their spatial and temporal integration within an indigenous cosmological framework. Urton breaks new ground by demonstrating the indigenous merging of such forms of "precise knowledge" as astronomy, meteorology, agriculture, and the correlation of astronomical and biological cycles within a single calendar system. More than sixty diagrams clarify this Quechua system of astronomy and relate it to more familiar principles of Western astronomy and cosmology.

What is unorthodox in this book? Much has happened in the last few years, especially in terms of the somewhat surpris ing rate at which the theories presented herein have been gaining increasing acceptance and support even by the most skeptical professionals. Nevertheless, the purpose of this up-dated Preface is not to tell the biographical and acceptance story behind this book, but to bring together some non-physical and non technical conclusions for those readers who find the physico-mathematical sections of this book too difficult to follow. A secondary purpose is to present here some newer conclu sions, especially in general philosophy and in aesthetics. Yet, the main physico philosophical conclusions presented in this book are not to be summarized here. For that purpose one must tum to the text itself. * * * The theories presented here have been developed in total isolation. They were never presented in "professional conferences", as most current writers do. Whether or not that was important remains to be seen. Hence, all I can state to critics and enthusiastic follow ers alike is the fact that I do not belong to any 'formal discipline', 'pressure group', or 'pro fessional organization'.

It is available to read and download as a PDF version on the Oxford Academic platform. General Relativity is a beautiful geometric theory, simple in its mathematical formulation but leading to numerous consequences with striking physical interpretations: gravitational waves, black holes, cosmological models, and so on. This introductory textbook is written for mathematics students interested in physics and physics students interested in exact mathematical formulations (or for anyone with a scientific mind who is curious to know more of the world we live in), recent remarkable experimental and observational results which confirm the theory are clearly described and no specialised physics knowledge is required. The mathematical level of Part A is aimed at undergraduate students and could be the basis for a course on General Relativity. Part B is more advanced, but still does not require sophisticated mathematics. Based on Yvonne Choquet-Bruhat's more advanced text, General Relativity and the Einstein Equations, the aim of this book is to give with precision, but as simply as possible, the foundations and main consequences of General Relativity. The first five chapters from General Relativity and the Einstein Equations have been updated with new sections and chapters on black holes, gravitational waves, singularities, and the Reissner-Nordström and interior Schwarzchild solutions. The rigour behind this book will provide readers with the perfect preparation to follow the great mathematical progress in the actual development, as well as the ability to model, the latest astrophysical and cosmological observations. The book presents basic General Relativity and provides a basis for understanding and using the fundamental theory.
