Following an introductory chapter on stellar fundamentals, the story begins of the lives and deaths of the stars. The authors take us on a journey from the sun, a comparatively young star, to supernovae - manifestations of dramatic death. On the way, the reader, advanced undergraduate or beginning postgraduate, is presented with such topics as stellar evolution, the hydrodynamics of stellar interiors, variability, and solar and stellar activity. This comprehensive but rigorous text, building on the theoretical and observational advances of recent years - for instance, astrophysical theory in the light of Supernova 1987A - is required reading for all serious students of astronomy.
The 1985/86 apparition of Halley's Comet turned out to be the most important apparition of a comet ever. It provided a worldwide science community with a wealth of exciting new discoveries, the most remarkable of which was undoubtedly the first image of a cometary nucleus. Halley's Comet is the brightest periodic comet, and the most famous of the 750 known comets. With its 76-year period, its recent appearance was truly a "once-in-a-lifetime" observational opportunity. The 1985/86 apparition was the thirtieth consecutive recorded apparition. Five apparitions ago, the English astronomer Edmond Halley discovered the periodicity of "his" comet and correctly predicted its return in 1758, a trium...
Conference on stellar chromospheres and their compositions.
The first of its kind, the Symposium on the Future of the Universe and the Future of our Civilization examined the current status and future evolution of the Universe, the Galaxy, the stars and the Sun. Among the major subjects of discussion were: (1) How was our Universe born? (2) How do the Sun and the stars evolve? (3) What is the destiny of the solar system and the Universe? (4) What are the origins and the future of the biosphere of the Earth? (5) What are the prospects of survival of human civilization?Special attention was devoted to analysis of humanitarian and philosophical problems of evolution of humankind on the planet Earth and in the Universe. Among them were methodological, economic, sociological and medical aspects of the progress of civilization. Scientists from different countries put forward some practical proposals, including those describing the possible ways out of the systemic crisis of our civilization.

International collaboration in scientific research & the rise of large science projects are two significant outgrowths of the scientific revolution of the past century. This report examines the factors that may warrant or facilitate international collaboration in large science projects or, conversely, that may favor the U.S. pursuing projects independently. It identifies the challenges raised by international collaboration & explores approaches that can promote the successful planning & execution of international projects. Covers: high-energy physics; fusion energy research; scientific activities in space; & neutron sources & synchrotrons.
"Though fields such as art history, the history of philosophy, and intellectual history have been around for a long time, the author's interest is in the history of what scholars in all of these fields are doing in common. This book looks beyond the humanities to the practice of disciplined inquiry more generally, bringing together the history of the humanities and the sciences under the guise of a unified search for patterns"--
