Cosmological Crossroads by Spiros Cotsakis,Eleftherios Papantonopoulos Pdf
This book has grown out of lectures held at a summer school on cosmology, in response to an ever increasing need for an advanced textbook that addresses the needs of both postgraduate students and nonspecialist researchers from various disciplines ranging from mathematical physics to observational astrophysics. Bridging the gap between standard textbook material in cosmology and the forefront of research, this book also constitutes a modern source of reference for the experienced researcher in classical and quantum cosmology.
At the Crossroads of the Earth and the Sky by Gary Urton Pdf
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.

Cosmology, Physics, and Philosophy by Benjamin Gal-Or Pdf
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'.
Introduction to General Relativity, Black Holes, and Cosmology by Yvonne Choquet-Bruhat Pdf
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-Nordstrom 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.

Learn the myths and legends behind this beloved goddess plus practices and suggestions for making Hekate part of your spiritual path. Courtney Weber (author of Brigid and The Morrigan) offers an informed, accessible journey through the lore and history of Hekate, the ancient goddess of crossroads, ghosts, and witchcraft, and reflects on Hekate’s relevance today. Tools and techniques for incorporating this goddess into your personal journey round out the book. Similar to her other works, Weber strikes a balance between the scholarly and the spiritual. Her exploration of Hekate combines solid research with practical, modern applications. The spiritual content is accessible to anyone with an interest in witchcraft, regardless of their faith or background. Each chapter focuses on a different aspect of Hekate, exploring original mythology, historical context, and contemporary connotations, concluding with spells and personal rituals. The final chapter is a grimoire full of rituals, offerings, and other practices designed to help readers align themselves with this extraordinary goddess. The book also explores magickal ethics, what it means to be a witch in the twenty-first century, and best practices for successful witchcraft.
God, Humanity, and the Universe by Alexei V. Nesteruk Pdf
The main objective of this book on cosmology and theology is to reassess the current approach to research in the field of interaction, mediation, and dialogue between modern cosmology and Christian theology (Eastern Orthodox theology in particular). This project was part of wide-ranging cross-disciplinary research undertaken by scientists, philosophers, and theologians across the world within the framework of Science & Orthodoxy around the World, run by the National Hellenic Research Foundation (Athens) from 2019 to 2023. The project and this publication contribute to the large-scale academic activity in the field of science and religion (or science and theology) with a particular accent on the contribution of Eastern Orthodox theology to this dialogue, as well as to the venues of advancement of this theology given the recent breakthroughs in cosmology, physics, and philosophy. The book also underlines the importance of expressing cosmological ideas theologically, symbolically, and scientifically in the wide context of culture and humanity's sociopolitical and environmental predicaments.
Astronomy and Astrophysics Abstracts by S. Böhme,W. Fricke,H. Hefele,I. Heinrich,W. Hofmann,D. Krahn,V. R. Matas,L. D. Schmadel,G. Zech Pdf
Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is devoted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documenta tion of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, compared to which our system of accumu lating abstracts for about six months offers the advantage of greater convenience for the user. Volume 31 contains literature published in 1982 and received before July 15, 1982; some older literature which was received late and which is not recorded in earlier volumes is also included. We acknowledge with thanks contributions to this volume by Dr. J. Bouska, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English .
String Theory Research Progress by Ferenc N. Balogh Pdf
String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional point particles that form the basis for the standard model of particle physics. The phrase is often used as shorthand for Superstring theory, as well as related theories such as M-theory. By replacing the point-like particles with strings, an apparently consistent quantum theory of gravity emerges. Moreover, it may be possible to 'unify' the known natural forces (gravitational, electromagnetic, weak nuclear and strong nuclear) by describing them with the same set of equations. Studies of string theory have revealed that it predicts higher-dimensional objects called branes. String theory strongly suggests the existence of ten or eleven (in M-theory) space-time dimensions, as opposed to the usual four (three spatial and one temporal) used in relativity theory.
Narrating History, Home, and Dyaspora by Maia L. Butler,Joanna Davis-McElligatt,Megan Feifer Pdf
Contributions by Cécile Accilien, Maria Rice Bellamy, Gwen Bergner, Olga Blomgren, Maia L. Butler, Isabel Caldeira, Nadège T. Clitandre, Thadious M. Davis, Joanna Davis-McElligatt, Laura Dawkins, Megan Feifer, Delphine Gras, Akia Jackson, Tammie Jenkins, Shewonda Leger, Jennifer M. Lozano, Marion Christina Rohrleitner, Thomás Rothe, Erika V. Serrato, Lucía Stecher, and Joyce White Narrating History, Home, and Dyaspora: Critical Essays on Edwidge Danticat contains fifteen essays addressing how Edwidge Danticat’s writing, anthologizing, and storytelling trace, (re)construct, and develop alternate histories, narratives of nation building, and conceptions of home and belonging. The prolific Danticat is renowned for novels, collections of short fiction, nonfiction, and editorial writing. As her experimentation in form expands, so does her force as a public intellectual. Danticat’s literary representations, political commentary, and personal activism have proven vital to classroom and community work imagining radical futures. Among increasing anti-immigrant sentiment and containment and rampant ecological volatility, Danticat’s contributions to public discourse, art, and culture deserve sustained critical attention. These essays offer essential perspectives to scholars, public intellectuals, and students interested in African diasporic, Haitian, Caribbean, and transnational American literary studies. This collection frames Danticat’s work as an indictment of statelessness, racialized and gendered state violence, and the persistence of political and economic margins. The first section of this volume, “The Other Side of the Water,” engages with Danticat’s construction and negotiation of nation, both in Haiti and the United States; the broader dyaspora; and her own, her family’s, and her fictional characters’ places within them. The second section, “Welcoming Ghosts,” delves into the ever-present specter of history and memory, prominent themes found throughout Danticat’s work. From origin stories to broader Haitian histories, this section addresses the underlying traumas involved when remembering the past and its relationship to the present. The third section, “I Speak Out,” explores the imperative to speak, paying particular attention to the narrative form with which such telling occurs. The fourth and final section, “Create Dangerously,” contends with Haitians’ activism, community building, and the political and ecological climate of Haiti and its dyaspora.
