Available in PDF, EPUB and Kindle. Book excerpt: The field of astrophysics is in the midst of a technologically driven renaissance, as fundamental discoveries are being made with astonishing frequency. In the last decade, new detectors in space, on earth, and deep underground have, when coupled with the computational power of modern computers, revolutionized our knowledge and understanding of the astronomical world. This is a great time for a student of any age to become acquainted with the remarkable universe in which we live. This volume is a collection of essays, originally presented orally to a diverse group of students and professionals, which reveal the most fertile areas for future study of astronomy and astrophysics. The emphasis of this work is on the clear description of the current state of our knowledge as a preparation for the future unraveling of the mysteries of the universe that appear today as most fundamental and most amenable to solution. A stellar group of astronomers and astrophysicists describes the directions and styles of work that they think are most likely to lead to progress. Bibliographical notes at the end of each presentation provide guidance for the reader who wishes to go more deeply into a given subject. Unsolved Problems in Astrophysics is a uniquely stimulating introduction to some of the most important topics in modern astrophysics.

Download or read book The World s 20 Greatest Unsolved Problems written by John R. Vacca and published by Prentice-Hall PTR. This book was released on 2005 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Phebe Hedges, a woman in East Hampton, New York, walked into the sea in 1806, she made visible the historical experience of a family affected by the dreaded disorder of movement, mind, and mood her neighbors called St.Vitus's dance. Doctors later spoke of Huntington’s chorea, and today it is known as Huntington's disease. This book is the first history of Huntington’s in America. Starting with the life of Phebe Hedges, Alice Wexler uses Huntington’s as a lens to explore the changing meanings of heredity, disability, stigma, and medical knowledge among ordinary people as well as scientists and physicians. She addresses these themes through three overlapping stories: the lives of a nineteenth-century family once said to “belong to the disease”; the emergence of Huntington’s chorea as a clinical entity; and the early-twentieth-century transformation of this disorder into a cautionary eugenics tale. In our own era of expanding genetic technologies, this history offers insights into the social contexts of medical and scientific knowledge, as well as the legacy of eugenics in shaping both the knowledge and the lived experience of this disease.

Download or read book The Five Biggest Unsolved Problems in Science written by Arthur W. Wiggins and published by Wiley (TP). This book was released on 2003-09-12 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: An in-depth look at the most intriguing puzzles in science today In this illuminating book, professors Arthur Wiggins and Charles Wynn explore what they believe are the five biggest science problems: Physics: Why do some particles have mass, while others have none? Chemistry: By what series of chemical reactions did atoms form the first living things? Biology: What is the complete structure and function of the proteome? Geology: Is accurate, long-range weather forecasting possible? Astronomy: Why is the universe expanding faster and faster? Wiggins and Wynn carefully explain each of these problems, then discuss the theories that address them. Some of the many topics covered include string theory, the human genome, chaos theory, and protein folding. Featuring humorous illustrations from renowned science cartoonist Sidney Harris, this book invites you to explore the events that led to these problems and the cutting-edge efforts being made to solve them. The authors also provide Idea Folders, which contain additional details about the unsolved problems, and Resources for Digging Deeper, such as books, periodicals, and Web sites.
Download or read book The Story of Collapsing Stars written by Pankaj S. Joshi and published by Oxford University Press, USA. This book was released on 2015 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book journeys into one of the most fascinating intellectual adventures of recent decades - understanding and exploring the final fate of massive collapsing stars in the universe. The issue is of great interest in fundamental physics and cosmology today, from both the perspective of gravitation theory and of modern astrophysical observations. This is a revolution in the making and may be intimately connected to our search for a unified understanding of the basic forces of nature, namely gravity that governs the cosmological universe, and the microscopic forces that include quantum phenomena. According to the general theory of relativity, a massive star that collapses catastrophically under its own gravity when it runs out of its internal nuclear fuel must give rise to a space-time singularity. Such singularities are regions in the universe where all physical quantities take their extreme values and become arbitrarily large. The singularities may be covered within a black hole, or visible to faraway observers in the universe. Thus, the final fate of a collapsing massive star is either a black hole or a visible naked singularity. We discuss here recent results and developments on the gravitational collapse of massive stars and possible observational implications when naked singularities happen in the universe. Large collapsing massive stars and the resulting space-time singularities may even provide a laboratory in the cosmos where one could test the unification possibilities of basic forces of nature.

Download or read book Dynamics of Extremal Black Holes written by Stefanos Aretakis and published by Springer. This book was released on 2018-11-02 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief presents in a self-contained, non-technical and illustrative fashion the state-of-the-art results and techniques for the dynamics of extremal black holes. Extremal black holes are, roughly speaking, either maximally rotating or maximally charged. Astronomical observations suggest that near-extremal (stellar or supermassive) black holes are ubiquitous in the universe. The book presents various recently discovered characteristic phenomena (such as the horizon instability) that have enhanced our understanding of the dynamics of extremal black holes. The topics should be of interest to pure mathematicians, theoretical physicists and astronomers. This book provides common ground for communication between these scientific communities.

Theoretical concepts are emphasized, but no other book for the layman explains how model universes are generated, and how they function as the templates against which ours is compared and analyzed. Background material is provided in the first four chapters; the current picture and how it was attained are discussed in the next four chapters; and some unsolved problems and conjectured solutions are explored in the final chapter.
Download or read book Order and Chaos in Dynamical Astronomy written by George Contopoulos and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is one of the first to provide a general overview of order and chaos in dynamical astronomy. The progress of the theory of chaos has a profound impact on galactic dynamics. It has even invaded celestial mechanics, since chaos was found in the solar system which in the past was considered as a prototype of order. The book provides a unifying approach to these topics from an author who has spent more than 50 years of research in the field. The first part treats order and chaos in general. The other two parts deal with order and chaos in galaxies and with other applications in dynamical astronomy, ranging from celestial mechanics to general relativity and cosmology.
