This study of archaeoastronomy looks at more than 2,500 communal tombs and sanctuaries from around the Mediterranean. After a brief discussion of Hoskin's aims and the methodology for his fieldwork, individual chapters focus on evidence from particular regions: Malta, Gozo, the Balearics, Iberia, southern France, Corsica and Sardinia, Sicily and Pantelleria, Tunisia, Algeria and Morocco. The author concludes that in most of these regions the monuments faced sunrise, or more generally the sun when it was rising or climbing in the sky. Along the Mediterranean coast of France, however, there is a reverse sunset custom; in North Africa tombs faced downhill and in a Minoan cemetery on Crete all the tombs faced moonrise and look towards a mountain on whose peak was a sanctuary probably sacred to a lunar god. 264p, b/w figs and photos throughout, tables (Ocarina Books 2001) ` adorned with dozens of beautiful photographs, technical diagrams, and an extraordinary Corpus Mensurarum.....a living masterpiece in the field of archaeoastronomy ' - Juan Antonio Belmonte, Instituto de Astroficia de Canarias `
The myths of the Aztec and Maya derive from a shared Mesoamerican cultural tradition. This is very much a living tradition, and many of the motifs and gods mentioned in early sources are still evoked in the lore of contemporary Mexico and Guatemala. Professor Taube discusses the different sources for Aztec and Maya myths. The Aztec empire began less than 200 years before the Spanish conquest, and our knowledge of their mythology derives primarily from native colonial documents and manuscripts commissioned by the Spanish. The Maya mythology is far older, and our knowledge of it comes mainly from native manuscripts of the Classic period, over 600 years before the Spanish conquest. Drawing on these sources as well as nineteenth- and twentieth-century excavations and research, including the interpretation of the codices and the decipherment of Maya hieroglyphic writing, the author discusses, among other things, the Popol Vuh myths of the Maya, the flood myth of Northern Yucatan, and the Aztec creation myths.
The Monadology (French: La Monadologie, 1714) is one of Gottfried Leibniz's best known works representing his later philosophy. It is a short text which sketches in some 90 paragraphs a metaphysics of simple substances, or monads. In it, he offers a new solution to mind and matter interaction by means of a pre-established harmony expressed as the 'Best of all possible worlds' form of optimism.
This first English translation makes avail­able to English-speaking readers a power­ful modern Mexican novel, first published in 1961. Fernando Benítez, well-known Mexican author, journalist, and winner of Mexico's 1968 best-book award, exploits a true but little-known incident by build­ing it into a tightly structured, tense, and tragic novel of social protest. The incident on which the novel is based is a bloody rebellion against the village feudal master touched off by joking comment on the "poisoning" of the water as one of Don Ulises's men is pushed into the plaza fountain. Feed­ing on itself, the rumor spreads that the "boss" has poisoned the local spring, and rebellion follows, with its violent and unforeseen consequences. The result is a frightening look at one of Mexico's major social problems and glaring ironies--that over fifty years after a revolution fought by the peasant and for the peasant, most rural groups are still living below the national economic standard.
In this book, the interesting results of similar works carried out by both authors independently, is presented in a unique manner. This book is written as a token of exchange between the East and the West and it is hoped that it will lead to greater cooperation between the scientists.
This textbook is intended to provide a foundation for a one-semester introductory course on the advanced mathematical methods that form the cornerstones of the hard sciences and engineering. The work is suitable for first year graduate or advanced undergraduate students in the fields of Physics, Astronomy and Engineering. This text therefore employs a condensed narrative sufficient to prepare graduate and advanced undergraduate students for the level of mathematics expected in more advanced graduate physics courses, without too much exposition on related but non-essential material. In contrast to the two semesters traditionally devoted to mathematical methods for physicists, the material in this book has been quite distilled, making it a suitable guide for a one-semester course. The assumption is that the student, once versed in the fundamentals, can master more esoteric aspects of these topics on his or her own if and when the need arises during the course of conducting research. The book focuses on two core subjects: complex analysis and classical techniques for the solution of ordinary and partial differential equations. These topics are complemented with occasional terse reviews of other material, including linear algebra, to the extent required to ensure the book can be followed from end-to-end. This textbook is designed to provide a framework for a roughly 12 week course, with 3 weeks devoted to complex variables, a 1 week refresher on linear algebra, followed by 5 and 3 weeks devoted to ordinary and partial differential equations, respectively. This schedule leaves time for a couple of exams. The narrative is complemented with ample problem sets, including detailed guides to solving the problems.
This text provides a quantitative introduction to general relativity for advanced undergraduate and graduate students.
This book explores the role of singularities in general relativity (GR): The theory predicts that when a sufficient large mass collapses, no known force is able to stop it until all mass is concentrated at a point. The question arises, whether an acceptable physical theory should have a singularity, not even a coordinate singularity. The appearance of a singularity shows the limitations of the theory. In GR this limitation is the strong gravitational force acting near and at a super-massive concentration of a central mass. First, a historical overview is given, on former attempts to extend GR (which includes Einstein himself), all with distinct motivations. It will be shown that the only possible algebraic extension is to introduce pseudo-complex (pc) coordinates, otherwise for weak gravitational fields non-physical ghost solutions appear. Thus, the need to use pc-variables. We will see, that the theory contains a minimal length, with important consequences. After that, the pc-GR is formulated and compared to the former attempts. A new variational principle is introduced, which requires in the Einstein equations an additional contribution. Alternatively, the standard variational principle can be applied, but one has to introduce a constraint with the same former results. The additional contribution will be associated to vacuum fluctuation, whose dependence on the radial distance can be approximately obtained, using semi-classical Quantum Mechanics. The main point is that pc-GR predicts that mass not only curves the space but also changes the vacuum structure of the space itself. In the following chapters, the minimal length will be set to zero, due to its smallness. Nevertheless, the pc-GR will keep a remnant of the pc-description, namely that the appearance of a term, which we may call "dark energy", is inevitable. The first application will be discussed in chapter 3, namely solutions of central mass distributions. For a non-rotating massive object it is the pc-Schwarzschild solution, for a rotating massive object the pc-Kerr solution and for a charged massive object it will be the Reissner-Nordström solution. This chapter serves to become familiar on how to resolve problems in pc-GR and on how to interpret the results. One of the main consequences is, that we can eliminate the event horizon and thus there will be no black holes. The huge massive objects in the center of nearly any galaxy and the so-called galactic black holes are within pc-GR still there, but with the absence of an event horizon! Chapter 4 gives another application of the theory, namely the Robertson-Walker solution, which we use to model different outcomes of the evolution of the universe. Finally the capability of this theory to predict new phenomena is illustrated.
