Book Description
Although Charles Darwin's theory of evolution laid the foundations of modern biology, it did not tell the whole story. Most remarkably, The Origin of Species said very little about, of all things, the origins of species. Darwin and his modern successors have shown very convincingly how inherited variations are naturally selected, but they leave unanswered how variant organisms come to be in the first place. In Symbiotic Planet, renowned scientist Lynn Margulis shows that symbiosis, which simply means members of different species living in physical contact with each other, is crucial to the origins of evolutionary novelty. Ranging from bacteria, the smallest kinds of life, to the largest -- the living Earth itself -- Margulis explains the symbiotic origins of many of evolution's most important innovations. The very cells we're made of started as symbiotic unions of different kinds of bacteria. Sex -- and its inevitable corollary, death -- arose when failed attempts at cannibalism resulted in seasonally repeated mergers of some of our tiniest ancestors. Dry land became forested only after symbioses of algae and fungi evolved into plants. Since all living things are bathed by the same waters and atmosphere, all the inhabitants of Earth belong to a symbiotic union. Gaia, the finely tuned largest ecosystem of the Earth's surface, is just symbiosis as seen from space. Along the way, Margulis describes her initiation into the world of science and the early steps in the present revolution in evolutionary biology; the importance of species classification for how we think about the living world; and the way "academic apartheid" can block scientific advancement. Written with enthusiasm and authority, this is a book that could change the way you view our living Earth.

Book Description
Many aspects of symbiotic stars have long puzzled astronomers. For instance while most students of the subject have considered them binary, many have at different times supported single star models. The nature of their outbursts is uncertain, while the dividing line between symbiotic stars and novae is unclear. In any case doubts can even be raised as to whether a class of "Symbiotic Stars" really exists. Much new data has been obtained in recent years, in particular from the study of radiation outside the visual region. Many symbiotic stars have been studied in the UV with IUE since 1978, while X-rays were det ected in a few cases with the Einstein satellite. There have been a num ber of infrared and radio studies, and the number of known symbiotic stars has also considerably increased. Furthermore theoretical ideas have in recent years been considerably enriched by concepts of stellar winds, and accretion phenomena in binaries including accretion disks. It was there fore extremely opportune and timely to hold the first international meet ing exclusively devoted to these stars, so as to consider the new results from such a wide range of observations in different spectral regions, and the conclusions which can be drawn for possible models as well as theories of the nature and structure of symbiotic stars. After a session devoted to new observations in different spectral regions, a session was spent considering some individual stars.

Book Description
Stars are mostly found in binary and multiple systems, with at least 50% of all solar-like stars having companions; this fraction approaches 100% for the most massive stars. A large proportion of these systems interact and alter the structure and evolution of their components, leading to exotic objects such as Algol variables, blue stragglers and other chemically peculiar stars, but also to phenomena such as non-spherical planetary nebulae, supernovae and gamma-ray bursts. While it is understood that binaries play a critical role in the Initial Mass Function, the interactions among binary systems significantly affect the dynamical evolution of stellar clusters and galaxies. This interdisciplinary volume presents results from state-of-the-art models and observations aimed at studying the impact of binaries on stellar evolution in resolved and unresolved populations. Serving as a bridge between observational and theoretical astronomy, it is a comprehensive review for researchers and advanced students of astrophysics.

Book Description
At the crossroads of philosophy and science, the sometimes-dry topics of evolution and ecology come alive in this new collection of essays--many never before anthologized. Learn how technology may be a sort of second nature, how the systemic human fungus Candida albicans can lead to cravings for carrot cake and beer, how the presence of life may be why there's water on Earth, and many other fascinating facts. The essay "Metametazoa" presents perspectives on biology in a philosophical context, demonstrating how the intellectual librarian, pornographer, and political agitator Georges Bataille was influenced by Russian mineralogist Vladimir Vernadsky and how this led to his notion of the absence of meaning in the face of the sun--which later influenced Jacques Derrida, thereby establishing a causal chain of influence from the hard sciences to topics as abstract as deconstruction and post-modernism. In "Spirochetes Awake" the bizarre connection between syphilis and genius in the life of Friedrich Nietzsche is traced. The astonishing similarities of the Acquired-Immune-Deficiency-Syndrome symptoms with those of chronic spirochete infection, it is argued, contrast sharply with the lack of evidence that "HIV is the cause of AIDS". Throughout these readings we are dazzled by the intimacy and necessity of relationships between us and our other planetmates. In our ignorance as "civilized" people we dismiss, disdain, and deny our kinship with the only productive life forms that sustain this living planet.

Book Description
•"Prove to me that God does not exist." •"God has designed every being to be this way. Evolution is a farce." •"God's existence is proven by the Bible.” •"Hitler and Stalin were Atheists and look at what happened!" These are but a few of the comments you may hear from people who have faith in a god. We depart on a guided thought experiment to understand how religion came to be, why religion has been a mainstay in modernity and what armamentarium to use in our fight against religious zealots. If you are a theist, the purpose of this book is to reason you out of something you had no reason to believe in the first place. If you are already on the fence, I look to burn down that structure. As I plant the flag for all to see, we will journey through fables, morality, science, and sin and verify if religion can, in fact, be eradicated. Born in Brentwood, NY, Orlando Rodriguez has moved many times since his childhood. He settled down in Manhattan in 2002. In what can only be described as love at first sight, he met and married his wife in 2003 and has three children. After living in Manhattan for several years, they all moved to Freehold, NJ, where they enjoy the relaxed life on weekends. Orlando’s hobbies include astronomy, working out, playing the guitar and the violin. The True Nature Of Human Nature Is Orlando’s first published work. His next book will be called When Dinosaurs Fall.

Book Description
Modern x-ray data, available through online archives, are important for many astronomical topics. However, using these data requires specialized techniques and software. Written for graduate students, professional astronomers and researchers who want to start working in this field, this book is a practical guide to x-ray astronomy. The handbook begins with x-ray optics, basic detector physics and CCDs, before focussing on data analysis. It introduces the reduction and calibration of x-ray data, scientific analysis, archives, statistical issues and the particular problems of highly extended sources. The book describes the main hardware used in x-ray astronomy, emphasizing the implications for data analysis. The concepts behind common x-ray astronomy data analysis software are explained. The appendices present reference material often required during data analysis.

Book Description
Dr Kenyon has researched and assembled here all the existing data for the known symbiotic stars, in which a dwarf star accretes material from its red giant companion. In this book he summarises observational material covering the eruptive and quiescent phases of these objects, and emphasises the important astrophysical problems raised and resolved by results at infrared, optical, radio, ultraviolet and X-ray wavelengths. Physical models for the eruptive and quiescent phases and the long-term evolution of symbiotic stars are discussed, with the goal of developing observational diagnostics that serve to test the basic theories. The book concludes with a detailed appendix and bibliography that will aid researchers interested in the history of individual symbiotic systems and confirm this volume as an indispensable handbook at any observatory where research on stellar objects in undertaken.

Book Description
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 32 contains literature published in 1982 and received before February 11, 1983; 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. Bou~a, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English.
