A sophisticated introduction to how astronomers identify, observe, and understand black holes Emitting no radiation or any other kind of information, black holes mark the edge of the universe—both physically and in our scientific understanding. Yet astronomers have found clear evidence for the existence of black holes, employing the same tools and techniques used to explore other celestial objects. In this sophisticated introduction, leading astronomer Charles Bailyn goes behind the theory and physics of black holes to describe how astronomers are observing these enigmatic objects and developing a remarkably detailed picture of what they look like and how they interact with their surroundi...

th Coinciding with the 300 anniversary of the publication of Newton's Principia The International Astronomical Union organized the colloquium No. 96 "The Few Body Problem" in Turku, Finland, June 14.-19.1987. It provided an opportunity to review the progress in the very field which caused Newton a headache, as Victor Szebehely reminded the audience in his introductory remarks. It is a measure of the difficulty and complication of the few body problem that even after 300 years so many aspects of the problem are still unsolved. To quote Szebehely again, "Sir Isaac established the rules, Poincare presented the challenges". Many of these challenges are reviewed in the present proceedings. The gr...
This book is a well-edited and comprehensive survey of the current research in the field of low-mass accretion powered compact binaries, that is, binary stars containing a white dwarf, neutron star, or black hole as the primary star and a Roche-lobe filling low-mass as the secondary star. These stars have reached a stage in their evolution where the transfer of mass from the giant phase onto a dwarf or sub-dwarf star demonstrates many different aspects of physics. The volume is essentially a complete analysis of these stars combining theory and observation, and covering observations of low-mass X-ray binaries and both magnetic and nonmagnetic cataclysmic variables, theories of stellar accretion, novae, and evolution of compact binaries.
Apart from a few articles, no comprehensive study has been written about the learned men and women in America with Czechoslovak roots. That’s what this compendium is all about, with the focus on immigration from the period of mass migration and beyond, irrespective whether they were born in their European ancestral homes or whether they have descended from them. Czech and Slovak immigrants, including Bohemian Jews, have brought to the New World their talents, their ingenuity, their technical skills, their scientific knowhow, and their humanistic and spiritual upbringing, reflecting upon the richness of their culture and traditions, developed throughout centuries in their ancestral home. Th...
In the centennial year, 1985-86, of Harlow Shapley's birth, the study of globular clusters was no less important to the development of astronomy than in 1915, when Shapley first noted their concentration on the sky. By 1917 Shapley had used the properties of the system of globular clusters to complete the Copernican revolution and locate the solar system, and its Earth-bound observers, far from the center of the Galaxy and the globular cluster distribution. Seven decades later, in the year of these proceedings, globular cluster research and the study of the system of globular clusters in our own and distant galaxies is undergoing a renaissance of activity. The introduction of new observation...
A concise introduction to the cutting-edge science of particle physics The standard model of particle physics describes our current understanding of nature's fundamental particles and their interactions, yet gaps remain. For example, it does not include a quantum theory of gravity, nor does it explain the existence of dark matter. Once complete, however, the standard model could provide a unified description of the very building blocks of the universe. Researchers have been chasing this dream for decades, and many wonder whether such a dream can ever be made a reality. Can the Laws of Physics Be Unified? is a short introduction to this exciting frontier of physics. The book is accessibly wri...
What we know about dark matter and what we have yet to discover Astronomical observations have confirmed dark matter’s existence, but what exactly is dark matter? In What Is Dark Matter?, particle physicist Peter Fisher introduces readers to one of the most intriguing frontiers of physics. We cannot actually see dark matter, a mysterious, nonluminous form of matter that is believed to account for about 27 percent of the mass-energy balance in the universe. But we know dark matter is present by observing its ghostly gravitational effects on the behavior and evolution of galaxies. Fisher brings readers quickly up to speed regarding the current state of the dark matter problem, offering relev...
When members of the media address politicians or report on social problems they assume that whatever issues are important in society must be a matter of public or state concern. Yet, the state or government is but a small part of any human society. Machan asserts that while the exact nature of government is a complicated question, only a totalitarian government aims to assume responsibility for every possible concern of its citizenry. Machan believes that the concept "public" is too broadly used to mean any problem that vocal citizens want government to address. Private Rights, Public Illusions focuses on the proper scope of government authority, especially in regard to people's economic or ...
