Lorentzian Geometrical Structures with Global Time, Gravity and Electrodynamics
Lorentzian Geometrical Structures with Global Time, Gravity and Electrodynamics
English | 2023 | ISBN: 3031237617 | 307 Pages | PDF EPUB (True) | 19 MB
This book investigates Lorentzian structures in the four-dimensional space-time, supplemented either by a covector field of the time-direction or by a scalar field of the global time. Furthermore, it proposes a new metrizable model of gravity. In contrast to the usual General Relativity theory, where all ten components of the symmetric pseudo-metric are independent variables, the gravity model presented here essentially depends only on a single four-covector field, and is restricted to have only three-independent components. However, the author proves that the gravitational field, governed by the proposed model and generated by some massive body, resting and spherically symmetric in some coordinate system, is given by a pseudo-metric that coincides with the well known Schwarzschild metric from General Relativity. The Maxwell equations and electrodynamics are also investigated in the framework of the proposed model. In particular, the covariant formulation of electrodynamics of moving dielectrics and para/diamagnetic media is derived.

Long Time Leaving Dispatches from Up South
Roy Blount Jr., "Long Time Leaving: Dispatches from Up South"
English | 2009 | ISBN: 1582434581, 0307266184 | EPUB | pages: 400 | 2.2 mb
In this acerbic, eminently quotable book, humorist Roy Blount Jr. focuses on his own dueling loyalties across the great American divide. Scholarly, raunchy, biting, and affable, Blount takes on topics ranging from chicken fingers and yellow dog Democrats to Elvis's toes while sharing some experiences of his own: chatting with Ray Charles, meeting an Okefenokee alligator, imagining Faulkner's tennis game, and being swept up, sort of, in the filming of Nashville. His yarns, analyses, and flights of fancy transcend all standard shades of Red, Blue, and in between.

Local Politics in Afghanistan A Century of Intervention in the Social Order
Local Politics in Afghanistan: A Century of Intervention in the Social Order By Conrad Schetter (editor)
2013 | 281 Pages | ISBN: 0199327920 | PDF | 2 MB
Afghanistan's people have contended with an almost continuous series of foreign interventions in their local affairs in the nineteenth and twentieth centuries. Not only have external powers such as British India, the Soviet Union, Pakistan and NATO meddled egregiously in local affairs, but sohave Afghan governments, including monarchical, Communist, Islamist and ostensibly democratic ones. While the robust resilience of the Afghan population in the face of external influence is widely recognised, how the local populations have concretely dealt with these interventions and how localpolitics is structured in Afghanistan still remain somewhat open questions. This volume sheds light on this phenomenon as well as illuminating the complexities of local politics in Afghanistan, analysing also how the local social order is disturbed or reinforced by outside intervention. It alsoadvances our understanding of Afghan society by presenting local politics in a way that frees it from the false binary of romanticisation and demonisation. A central theme is understanding how rational objectives play out in local politics and are guided by social factors such as trust, solidarity,reciprocity and patronage. The book also explores the role jirgas and shuras have played in negotiating between the local and external interventionists.

Life Beyond the Grave Christian Interfaith Perspectives
Alonzo L. Gaskill, "Life Beyond the Grave: Christian Interfaith Perspectives"
English | ISBN: 1944394788 | 2019 | 220 pages | EPUB | 478 KB
Surely no subject has captured the attention of men and women like that of death and the life beyond. Millions have sought with Job to know "if a man die, shall he live again?" (Job 14:14). And if there is a future state, what is its nature? How best may mortal men and women prepare for it? Indeed, death has ever remained life's most awesome mystery. In this book, representatives of several Christian groups address the topics of death and what lies beyond death from the vantage of their particular religious traditions.
