The Cosmic Century
Reviews the historical development of all the key areas of modern astrophysics.
Organizations and Strategies in Astronomy
Research and publications in the field of Astronomy have undergone dramatic changes in the last half-century. While activities just slowed down during World War II in the US and in Latin America, they were very strongly affected by the difficult conditions prevailing among the European belligerent nations. Half a century ago, re search activities were mostly confined to observatories (linked or not to universities) and usually separated from the teaching of physical sciences. Hence, directors of observatories played an important role in the choice of the research fields, and "schools" of research appeared at various places, de veloping specific instrumentation, reduction techniques and mathematical methods to achieve their scientific goals. Reorganising the research activities after the war was no minor under taking, specially because communications were interrupted for over five years and isolated continental Europe from overseas activities. Scarcity of observing instruments (some of them being requisitioned by occupy ing armies) , enormous gaps in the available litterature led to local research activities, conducted independently of similar efforts undertaken elsewhere.
Cooling Flows in Clusters and Galaxies
X-ray astronomers discovered the diffuse gas in clusters of galaxies about 20 years ago. It was later realized that the central gas density in some clusters, and in elliptical galaxies, is so high that radiative cooling is a significant energy loss. The cooling time of the gas decreases rapidly towards the centre of the cluster or galaxy and is less than a Hubble time within the innermost few hundred kiloparsecs. This results in a cooling flow in which the gas density rises in order to maintain pressure to support the weight of the overlying gas. The rate at which mass is deposited by the flow is inferred to be several hundreds of solar masses per year in some clusters. The fraction of clust...
First Steps in the Origin of Life in the Universe

Astrophysical Jets
Attilio Ferrari I want to recall here the basic points I raised at the beginning of the Workshop as the main targets of discussion (in the name of the Scientific Committee). I attempted to focus the attention of participants on the fact that, in many instances, we tend to discuss jets in terms of simple physics, more or less as one did at the time extragalactic radio sources were discovered: for instance, we still use equipartition arguments. However, we must realize that processes in jets, leading to their morphologies and energetics clearly depend on complex plasma phenomena. Therefore, the same standard arguments used to derive characteristic parameters should be questioned; some of the s...
Landscapes and Landforms of Switzerland
This book provides a comprehensive overview of the Landscapes and Landforms of Switzerland. It covers the country’s geological and tectonic context, together with its climatic context, geomorphological history, structural and karstic landscapes, glacial and periglacial landscapes, landscapes with natural hazards, geomorphology and society, and the preservation of its geomorphological heritage. Richly illustrated, it presents case studies on some of the country’s most famous natural sites, including the Matterhorn, Aletsch Glacier, Sardona Tectonic Arena, and Engadine, among others.
Earth-Moon Relationships
The Conference on the Earth-Moon relationships brought together a number of distinguished scientists from different fields - such as Astronomy, Celestial Mechanics, Chemistry - but also scholars of Literature and Art, to discuss these relationships, their origins, and their influence on human activities and beliefs.
The Science of Astrobiology
Since the publication of The New Science of Astrobiology in the year 2001—the first edition of the present book—two significant events have taken place raising the subject from the beginning of the present century to its present maturity. Firstly, in 2001 the Galileo Mission still had two years to complete its task, which turned out to be an outstanding survey of the Jovian system, especially of its intriguing satellite Europa. Secondly, the Cassini Huygens Mission was still on its way to Saturn. Its present success has surpassed all expectations of ESA and NASA. Astrobiologists still did not know that Titan was the fifth body in the Solar System that possibly contained a water ocean (including the Earth and the three Galilean satellites other than Io). For these reasons the book includes overviews of the evolutionary and molecular biology that are necessary. There is a discussion of other sectors of culture that are the natural frontiers of astrobiology, especially the humanities.
Retrying Galileo, 1633–1992
"This is must reading for historians of science and a delight for the interested public. From his access to many primary sources in the Vatican Library and from his broad knowledge of the history of the 17th century, Finocchiaro acquaints readers in an interesting manner with the historical facts of Galileo's trial, its aftermath, and its repercussions. Unlike many other works which present predetermined and, at times, prejudiced judgments, this work provides exhaustive evidence to allow readers to develop their own informed opinion on the subject.”—George V. Coyne, Director, Vatican Astronomical Observatory “The tragic condemnation of Galileo by the Roman Catholic Church in 1633 has b...
Morphological and Physical Classification of Galaxies
The morphological scheme devised by Hubble and followers to classify galaxies has proven over many decades to be quite effective in directing our quest for the fundamental pa rameters describing the extragalactic manifold. This statement is however far more true for spirals than for ellipticals. Echoing the concluding remarks in Scott Tremaine's sum mary talk at the Princeton meeting on Structure and Dynamics of Elliptical Galaxies, "the Hubble classification of spirals is useful because many properties of spirals (gas con tent, spiral arm morphology, bulge prominence, etc. ) all correlate with Hubble time. By contrast, almost nothing correlates with the elliptical Hubble sequence El to E7. ...
