A unique collection of thirty experiments ranging from ancient astronomy to cosmology, each containing one or more challenges for the reader. The progression here is from the Earth outward through the solar system to the stellar and galactic realm. Topics include the shape of the sky; Stonehenge as a stone-age abacus; determining the size of the Earth; the distance of the moon, stars and planets; planetary mass, density, temperature and atmosphere; the speed of light; the nature of the quiet and active sun; photometry and spectroscopy; star clusters and variable stars; and fundamental properties of stars.

This volume provides a state-of-the-art review of our current knowledge of brown dwarfs and very low-mass stars. The hunt for and study of these elusive objects is currently one of the most dynamic areas of research in astronomy for two reasons. Brown dwarfs bridge the gap between stars and planets, and they may constitute an important part of the 'dark matter' of the Universe. This volume presents review articles from a team of international authorities who gathered at a conference in La Palma to assess the spectacular progress that has been made in this field in the last few years.

Now approaching its tenth year, this hugely successful book presents an unusual attempt to publicise the field of Complex Dynamics. The text was originally conceived as a supplemented catalogue to the exhibition "Frontiers of Chaos", seen in Europe and the United States, and describes the context and meaning of these fascinating images. A total of 184 illustrations - including 88 full-colour pictures of Julia sets - are suggestive of a coffee-table book. However, the invited contributions which round off the book lend the text the required formality. Benoit Mandelbrot gives a very personal account, in his idiosyncratic self-centred style, of his discovery of the fractals named after him and Adrien Douady explains the solved and unsolved problems relating to this amusingly complex set.

Blazars (also known as BL Lac objects), first discovered in 1978, are unusually energetic objects in the extragalactic universe. About 200 are known or suspected. They are radio sources with highly variable optical and radio emission, as well as high polarisation, and their optical spectra normally have no distinguishable features. It is generally accepted that they belong to that class of galaxies with active galactic nuclei, which are presumed to be driven by infall of matter to a supermassive black hole. In this book researchers give a complete summary of the observations of blazars and the theoretical interpretation. A comprehensive listing of confirmed and candidate objects is included. Mechanisms in which the variability can arise from shocks and relativistic jets are discussed. There are at least four different answers given to the question: what is a blazar? This book is a complete overview of the violent activity observed in these extreme active galactic nuclei.

The deep economic recession that has occurred in all major sectors of the U.S. and global economy is a manifestation of the underlying contradictions of the capitalist system that has resulted in the accumulation of vast fortunes on one side and impoverishment, debt, and destitution on the other. In short, the crisis of global capitalism is the result of the immense disparities in wealth and income and a consequent widening gap between capital and labor.This ground-breaking book brings together a team of experts on the contemporary global capitalist political economy who are able to shed light on the inner workings of global capitalism and the capitalist globalization process that has led to the growth and development of capitalism from the national to the global level, with all its fundamental internal dynamics and contradictions operating on a world scale. It will make an important contribution to understanding the underlying causes of the current global economic crisis and show the way out of this crisis by way of a powerful critique of the global capitalist system that will ultimately go through a major economic, political, and social transformation.Analysis of the global capitalist crisis raises questions regarding the process of capitalist globalization, especially now that neoliberal economic policies have failed. Does this signal the end of capitalist globalization and the collapse of the global capitalist system? This book will take up these questions and entertain the possibility of a new beginning in the global political economy through an analysis of the next period of post-capitalist developments worldwide that may set the stage for the rise of socialism across the globe.
