Available in PDF, EPUB and Kindle. Book excerpt: Over the past few years, long-duration gamma-ray bursts (GRBs), including the subclass of X-ray flashes (XRFs), have been revealed to be a rare variety of Type Ibc supernova (SN Ibc). While all these events result from the death of massive stars, the electromagnetic luminosities of GRBs and XRFs exceed those of ordinary Type Ibc SNe by many orders of magnitude. The observed diversity of stellar death corresponds to large variations in the energy, velocity, and geometry of the explosion ejecta. Using multi-wavelength (radio, optical, X-ray) observations of the nearest GRBs, XRFs, and SNe Ibc, I show that GRBs and XRFs couple at least 1048 erg to relativistic material while SNe Ibc typically couple less than 1048 erg to their fastest (albeit non-relativistic) outflows. Specifically, I find that less than 3 percent of local SNe Ibc show any evidence for association with a GRB or XRF. Interestingly, this dichotomy is not echoed by the properties of their optical SN emission, dominated by the radioactive decay of Nickel-56; I find that GRBs, XRFs, and SNe Ibc show significant overlap in their optical peak luminosity and photospheric velocities. Recently, I identified a new class of GRBs and XRFs that are under-luminous in comparison with the statistical sample of GRBs. Owing to their faint high-energy emission, these sub-energetic bursts are only detectable nearby (z

Available in PDF, EPUB and Kindle. Book excerpt: Supernovae are among the most energetic phenomena in the Universe and - lated to almost all aspects of modern astrophysics including starburst gal- ies, cosmic ray acceleration, neutron star and black hole formation, nuc- osynthesis and ISM chemical enrichment, energy input to the ISM, cosmic distance scale determination, dark energy related cosmological acceleration, gamma-ray bursts, extra-solar system neutrino burst detection, gravity wave generation, and many more. Additionally, the past 15 years have been p- ticularly productive with many new results and new understanding due in particular to the closest SN in 400 years in SN 1987A in the Large M- ellanic Cloud, and the unusually bright and close SN 1993J and SN 1994I in the nearby galaxies M81 and M51, respectively. In addition, the disc- ery of the ?-ray burst GRB 980425 and its related supernova SN 1998bw, and the con?rmation of GRB 030329/SN 2003dh, tied the study of SNe and GRBs inextricably together. With the many developments since the last - jor supernova meeting in La Serena, Chile in 1997, we felt that it was an appropriate time to bring together experts and students interested in the subject for a meeting where SN and GRB properties and interrelationships could be discussed. The tenth anniversary of SN 1993J provided such an - portunity and, appropriately, the meeting was held in Spain where SN 1993J was discovered on the early morning of 28 March 1993 by a Spanish amateur astronomer, Francisco Garc ́ ?a.

Download or read book The Many Faces of Adam and Eve written by Bernard F. Batto and published by Wipf and Stock Publishers. This book was released on 2022-02-17 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contrary to popular opinion, the story of Adam and Eve is not confined to the book of Genesis. It has roots in prebiblical myth and continued to evolve long after the Bible was completed. Bernard F. Batto traces the development of the Adam and Eve story from its origins in Mesopotamian myth to its reformulation in Genesis and beyond—including its expansion in Jewish epigraphs such as 1 Enoch and the Life of Adam and Eve, and its place in Christian innovations such as the apostle Paul’s thesis that Christ is a second Adam, and in the thinking of church fathers such as Irenaeus, who held that Christ recapitulates all humankind in himself, and Augustine, whose doctrine of original sin interprets the Adam and Eve story. Batto also examines gnostic teachings about a heavenly Adam and an earthly Adam, and surveys rabbinical attempts from the Talmudic period to find hidden meanings in the Genesis story. Islam’s emphasis on Satan’s role in seducing Adam and Eve is also discussed, and the book concludes with Milton’s unforgettable retelling of the Adam and Eve story in Paradise Lost. Batto’s goal is not only to reveal the many faces given Adam and Eve throughout history, but also to understand the divergent cultural and theological factors powering this long, evolving tradition.

Available in PDF, EPUB and Kindle. Book excerpt: Ife` Kenyatta is the first in her bloodline in over 400 years to carry on the traditions of her ancestors, unaware of a destiny to be fulfilled and a cosmological prophecy she is plagued by savage dreams that literally draw blood; driving her to West Africa to seek answers. While traveling the interior of Nigeria at a secluded check point she is stopped and harassed. Escaping from the soldiers she is pursued by them for the mysterious death of one of their comrades. Fleeing from them she encounters a land bewitched with terrifying mirage-like barriers that protect the village where she must go; a village shrouded in mystery populated with spiritually advanced Seers and Shaman. There her only hope is to survive a deadly rites of passage that will empower her with the ability to command the elements, invoke the spirits of the dead and reside in two worlds; that of the living, and that of the dead. There she learns of the war in heaven before the creation of the human race so that she may prepare for an inevitable confrontation. Meanwhile the H20 Command Advanced Technologies vessel captained by Captain Fatima Jatari commissioned specifically for the investigation of unexplainable anomalies, accidents and incidents off the coast of Nigeria she and her crew stumble across the wreckage of what they perceive as a horrible shipping accident, until further investigation reveals the unspeakable; the unbelievable, a horror unimaginable. A thousand miles out in the Atlantic in the middle passage deep beneath the ocean's surface a four hundred year old abomination raises every full moon tormenting Nigeria's coast driving its citizens to the edge of madness. Somehow these two women must join forces to eliminate a common enemy and fulfill an ancient prophecy.

Download or read book The Many Faces of Coincidence written by Laurence Browne and published by Andrews UK Limited. This book was released on 2017-11-10 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although much has been said and written about coincidences, there is a marked absence when it comes to the development of a comprehensive model that incorporates the many different ways in which they can be understood and explained. One reason for this omission is undoubtedly the sharp divide that exists between those who find coincidences meaningful and those who do not, with the result that the conclusions of the many books and articles on the subject have tended to fall into distinct camps. The Many Faces of Coincidence attempts to remedy this impasse by proposing an inclusive categorisation for coincidences of all shapes and sizes. At the same time, some of the implications arising from the various explanations are explored, including the possibility of an underlying unity of mind and matter constituting the ground of being.

Download or read book Mathematical Aspects of Paradoxes in Cosmology written by Michal Křížek and published by Springer Nature. This book was released on 2023-07-05 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a mathematical and numerical analysis of many problems which lead to paradoxes in contemporary cosmology, in particular, the existence of dark matter and dark energy. It is shown that these hypothetical quantities arise from excessive extrapolations of simple mathematical models to the whole physical universe. Written in a completely different style to most books on General Relativity and cosmology, the important results take the form of mathematical theorems with precise assumptions and statements. All theorems are followed by a corresponding proof, or an exact reference to the proof. Some nonstandard topics are also covered, including violation of the causality principle in Newtonian mechanics, a critical mathematical and numerical analysis of Mercury's perihelion shift, inapplicability of Einstein's equations to the classical two-body problem due to computational complexity, non-uniqueness of the notion of universe, the topology of the universe, various descriptions of a hypersphere, regular tessellations of hyperbolic spaces, local Hubble expansion of the universe, neglected gravitational redshift in the detection of gravitational waves, and the possible distribution of mass inside a black hole. The book also dispels some myths appearing in the theory of relativity and in contemporary cosmology. For example, although the hidden assumption that Einstein's equations provide a good description of the evolution of the whole universe is considered to be obvious, it is just a null hypothesis which has not been verified by any experiment, and has only been postulated by excessive extrapolations of many orders of magnitude.

This book was released on 2004-09-08 with total page 948 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum Theory, together with the principles of special and general relativity, constitute a scientific revolution that has profoundly influenced the way in which we think about the universe and the fundamental forces that govern it. The Historical Development of Quantum Theory is a definitive historical study of that scientific work and the human struggles that accompanied it from the beginning. Drawing upon such materials as the resources of the Archives for the History of Quantum Physics, the Niels Bohr Archives, and the archives and scientific correspondence of the principal quantum physicists, as well as Jagdish Mehra's personal discussions over many years with most of the architects of quantum theory, the authors have written a rigorous scientific history of quantum theory in a deeply human context. This multivolume work presents a rich account of an intellectual triumph: a unique analysis of the creative scientific process. The Historical Development of Quantum Theory is science, history, and biography, all wrapped in the story of a great human enterprise. Its lessons will be an aid to those working in the sciences and humanities alike.

Download or read book The Two Faces of Islam written by Stephen Schwartz and published by Anchor. This book was released on 2003-09-09 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its formation in 1932, Saudi Arabia has been ruled by two interdependent families. The Al Sa’uds control politics and the descendants of Ibn Abd al-Wahhab impose Wahhabism—a violent, fanatical perversion of the pluralistic Islam practiced by most Muslims. Stephen Schwartz argues that Wahhabism, vigorously exported with the help of Saudi oil money, is what incites Palestinian suicide bombers, Osama bin Laden, and other Islamic terrorists throughout the world. Schwartz reveals the hypocrisy of the Saudi regime, whose moderate facade conceals state-sponsored repression and terrorism. He also raises troubling questions about Wahhabi infiltration of America’s Islamic community and about U.S. oil companies sanitizing Saudi Arabia’s image for the West. This sharp analysis and eye-opening expose illuminates the background to the September 11th terrorist attacks and offers new approaches for U.S. policy toward its closest ally in the Middle East.

Download or read book Supernova Explosions written by David Branch and published by Springer. This book was released on 2017-08-02 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: Targeting advanced students of astronomy and physics, as well as astronomers and physicists contemplating research on supernovae or related fields, David Branch and J. Craig Wheeler offer a modern account of the nature, causes and consequences of supernovae, as well as of issues that remain to be resolved. Owing especially to (1) the appearance of supernova 1987A in the nearby Large Magellanic Cloud, (2) the spectacularly successful use of supernovae as distance indicators for cosmology, (3) the association of some supernovae with the enigmatic cosmic gamma-ray bursts, and (4) the discovery of a class of superluminous supernovae, the pace of supernova research has been increasing sharply. This monograph serves as a broad survey of modern supernova research and a guide to the current literature. The book’s emphasis is on the explosive phases of supernovae. Part 1 is devoted to a survey of the kinds of observations that inform us about supernovae, some basic interpretations of such data, and an overview of the evolution of stars that brings them to an explosive endpoint. Part 2 goes into more detail on core-collapse and superluminous events: which kinds of stars produce them, and how do they do it? Part 3 is concerned with the stellar progenitors and explosion mechanisms of thermonuclear (Type Ia) supernovae. Part 4 is about consequences of supernovae and some applications to astrophysics and cosmology. References are provided in sufficient number to help the reader enter the literature.
