Exploring Ancient Skies brings together the methods of archaeology and the insights of modern astronomy to explore the science of astronomy as it was practiced in various cultures prior to the invention of the telescope. The book reviews an enormous and growing body of literature on the cultures of the ancient Mediterranean, the Far East, and the New World (particularly Mesoamerica), putting the ancient astronomical materials into their archaeological and cultural contexts. The authors begin with an overview of the field and proceed to essential aspects of naked-eye astronomy, followed by an examination of specific cultures. The book concludes by taking into account the purposes of ancient a...
It presents equations and derivations starting from a level that permits one to see the underlying physical ideas. There is no other book that does this on the market. The book presents an up-to-date overview on all essential topics but is concise where possible to keep it a practical resource for courses. The book is based on extensive experience in the class room. Its contents have been field-tested for years by students.
Focussing on the formulation of mathematical models for the light curves of eclipsing binary stars, and on the algorithms for generating such models, this book provides astronomers, both amateur and professional, with a guide for - specifying an astrophysical model for a set of observations - selecting an algorithm to determine the parameters of the model - estimating the errors of the parameters. It is written for readers with knowledge of basic calculus and linear algebra; appendices cover mathematical details on such matters as optimisation, co-ordinate systems, and specific models. While emphasising the physical and mathematical framework, the discussion remains close to the problems of actual implementation. The book concludes with chapters on specific models and approaches and the authors'views on the structure of future light-curve programs.
A complete record of the formal organisational and administrative proceedings of the XXVII General Assembly of the International Astronomical Union.
This book presents a complete summary of the author's twenty five years of experience in telescope design. It provides a general introduction to every aspect of telescope design. It also discusses the theory behind telescope design in depth, which makes it a good reference book for professionals. It covers Radio, Infrared, Optical, X-Ray and Gamma-Ray wavelengths. Originally published in Chinese.
As Andrzej Sapkowski was fleshing out his character Geralt of Rivia for a writing contest, he did not set out to write a science textbook--or even a work of science fiction. However, the world that Sapkowski created in his series The Witcher resulted in a valuable reflection of real-world developments in science and technology. As the Witcher books have been published across decades, the sorcery in the series acts as an extension of the modern science it grows alongside. This book explores the fascinating entanglement of science and magic that lies at the heart of Sapkowski's novel series and its widely popular video game and television adaptations. This is the first English-language book-le...
The text tells the story of man from a unique perspective; from the origin of life in this part of the galaxy to the highest achievements that this being has attained by exploring the several steps in his ascension, and detailing likely scenarios for such topics as the beginning of astronomy and philosophy and the parts that each of these have played in the creation of science.
This book contains the proceedings of the second joint research program on close binary systems between the People's Republic of China and the United States. The planning for the double stars conference developed gradually through several years of close cooperation between astronomers of the PRC and the US. Topics covered include interacting am binaries, H-alpha emission and polarization of RS CVn stars, observational approach to close binary evolution, the role of polarimetry in understanding close binary stars and their interactions, physical models for close binaries and logical constraints, and accretion disks in dwarf novae.
Gazing up at the heavens from our backyards or a nearby field, most of us see an undifferentiated mess of stars—if, that is, we can see anything at all through the glow of light pollution. Today’s casual observer knows far less about the sky than did our ancestors, who depended on the sun and the moon to tell them the time and on the stars to guide them through the seas. Nowadays, we don’t need the sky, which is good, because we’ve made it far less accessible, hiding it behind the skyscrapers and the excessive artificial light of our cities. How We See the Sky gives us back our knowledge of the sky, offering a fascinating overview of what can be seen there without the aid of a telesc...
