The Nebular Variables focuses on the nebular variables and their characteristics. Discussions are organized by type of nebular variable, namely, RW Aurigae stars, T Orionis stars, T Tauri stars, and peculiar nebular objects. Topics range from light variations of the stars to their spectroscopic and physical characteristics, spatial distribution, interaction with nebulosity, and evolutionary features. This volume is divided into four sections and consists of 25 chapters, the first of which provides general information on nebular variables, including their stellar associations and their classification into three distinct groups: RW Aurigae, T Orionis and T Tauri variables. These three groups of nebular variables are examined in more detail in the chapters that follow in terms of their light variations, spatial distribution, interaction with nebulosity, and spectroscopic, physical, and evolutionary characteristics. Visual and photoelectric light curves, mass loss determined spectroscopically, luminosities, and stellar radii are considered. The book also explores the possibility that some of the nebulae associated with certain nebular variables have evolved from a protoplanetary disc of material consisting of both gas and solid matter. Peculiar nebular variables such as the long period variable R Aquarii, Herbig-Haro objects, symbiotic variables, and infrared stars are analyzed as well. This book is written primarily for students and teachers of astronomy.

From September 5 until September 9, 1968, the IVth Colloquium on Variable Stars was held in Budapest, Hungary. The Colloquium was organized by a committee consisting of G.H. Herbig (President), A. Boyarchuk, M.W. Feast, D. McNamara, J.E. Merrill, D.J.K. O'Connell, V. Tsessevich, W. Wenzel. The local organization was placed in the hands of a Committee consist ing of members of the Konkoly Observatory, Budapest: L. Detre (Chairman), 1. Almar, Julia Balazs-Detre, K. Barlai, M. Ill, S. Kany6, M. Lovas and of J. Kovacs (Hungarian Academy of Sciences). The Colloquium was attended by about 90 scientists representing Argentina, Austria, Bulgaria, Canada, France, GDR, GFR, Hungary, Italy, The Netherlands, Poland, Roumania, South Africa, Sweden, United Kingdom, U.S.A., U.S.S.R. As chairmen acted at the sessions: M.W. Feast, G.H. Herbig, J. Sahade, A. Boyarchuk, W. Wenzel, F.B. Wood and L. Rosino. The contents of the present volume parallel closely the programme of the individual sessions of the Colloquium.

Gerald North's complete practical guide and resource package instructs amateur astronomers in observing and monitoring variable stars and other objects of variable brightness. Descriptions of the objects are accompanied by explanations of the background astrophysics, providing readers with real insight into what they are observing at the telescope. The main instrumental requirements for observing and estimating the brightness of objects by visual means and by CCD photometry are detailed, and there is advice on the selection of equipment. The book contains a CD-ROM packed with resources, including hundreds of light-curves and over 600 printable finder charts. Containing extensive practical advice, this comprehensive guide is an invaluable resource for amateur astronomers of all levels, from novices to more advanced observers. Gerald North is a lifelong amateur astronomer. In addition to being a member of the British Astronomical Association since 1977, he is also the author of many books, including Advanced Amateur Astronomy (Cambridge, 1997) and Observing the Moon (Cambridge, 2000).

Variable stars are fascinating objects to observe; found all over the sky, they change in brightness over time and can be seen with even the most basic of equipment. Variable star astronomy is one field in which amateur astronomers can still make significant contributions to science and in this highly accessible book David Levy teaches the reader how variable stars work, and how to observe them. Using simple, non-technical terms he explains how to get started with electronic (or CCD) observing, as well as how to observe variable stars through a small telescope or binoculars. Including a section on Southern hemisphere stars, the book covers various types of object that can be observed by amateur astronomers, including more exotic phenomena like gamma ray bursts, blazars, and polars. This book will serve to motivate anyone with even a basic interest in astronomy to begin observing these fascinating objects.

Many books on general astronomy have been published in recent years, but this one is exceptional in several respects. It not only provides the complete newcomer to astronomy with a broad picture, covering all aspects - historical, observational, space research methods, cosmology - but it also presents enough more advanced material to enable the really interested student to take matters further. Astronomy is essentially a mathematical science, but there are many people who are anxious to take more than a passing interest and yet are not equipped to deal with mathematical formulae. In this book, therefore, the mathematical sections are deliberately separated out, so that they can be passed over without destroying the general picture. The result is that the book will be equally useful to beginners, to more advanced readers, and to those who really want to go deeply into the subject - for instance at university level. The whole text is written with admirable clarity, and there are excellent illustrations, together with extensive appendices which give lists of objects of various types together with more detailed mathematical explanations. All in all, the book may be said to bridge the gap between purely popular works and more advanced treatises; as such it deserves a very wide circulation, and it will undoubtedly run to many future editions.

“A wonderfully lucid, accessible, and wide-ranging account of the boundary between justified and unjustified belief.” —Sam Harris, New York Times–bestselling author of The Moral Landscape and The End of Faith In this work synthesizing thirty years of research, psychologist, historian of science, and the world’s best-known skeptic Michael Shermer upends the traditional thinking about how humans form beliefs about the world. Simply put, beliefs come first and explanations for beliefs follow. The brain, Shermer argues, is a belief engine. From sensory data flowing in through the senses, the brain naturally begins to look for and find patterns, and then infuses those patterns with meaning. Our brains connect the dots of our world into meaningful patterns that explain why things happen, and these patterns become beliefs. Once beliefs are formed the brain begins to look for and find confirmatory evidence in support of those beliefs, which accelerates the process of reinforcing them, and round and round the process goes in a positive-feedback loop of belief confirmation. Shermer outlines the numerous cognitive tools our brains engage to reinforce our beliefs as truths. Interlaced with his theory of belief, Shermer provides countless real-world examples of how this process operates, from politics, economics, and religion to conspiracy theories, the supernatural, and the paranormal. Ultimately, he demonstrates why science is the best tool ever devised to determine whether or not a belief matches reality. “A must read for everyone who wonders why religious and political beliefs are so rigid and polarized—or why the other side is always wrong, but somehow doesn’t see it.” —Dr. Leonard Mlodinow, physicist and author of The Drunkard’s Walk and The Grand Design (with Stephen Hawking)
