Matters of Gravity

Matters of Gravity PDF Author: Scott Bukatman
Publisher: Duke University Press
ISBN: 0822384892
Category : Social Science
Languages : en
Pages : 314

Book Description
The headlong rush, the rapid montage, the soaring superhero, the plunging roller coaster—Matters of Gravity focuses on the experience of technological spectacle in American popular culture over the past century. In these essays, leading media and cultural theorist Scott Bukatman reveals how popular culture tames the threats posed by technology and urban modernity by immersing people in delirious kinetic environments like those traversed by Plastic Man, Superman, and the careening astronauts of 2001: A Space Odyssey and The Right Stuff. He argues that as advanced technologies have proliferated, popular culture has turned the attendant fear of instability into the thrill of topsy-turvydom, often by presenting images and experiences of weightless escape from controlled space. Considering theme parks, cyberspace, cinematic special effects, superhero comics, and musical films, Matters of Gravity highlights phenomena that make technology spectacular, permit unfettered flights of fantasy, and free us momentarily from the weight of gravity and history, of past and present. Bukatman delves into the dynamic ways pop culture imagines that apotheosis of modernity: the urban metropolis. He points to two genres, musical films and superhero comics, that turn the city into a unique site of transformative power. Leaping in single bounds from lively descriptions to sharp theoretical insights, Matters of Gravity is a deft, exhilarating celebration of the liberatory effects of popular culture.

Gravity Matters

Gravity Matters PDF Author: Sonja Ruth Greckol
Publisher: Inanna Publications & Education
ISBN:
Category : Poetry
Languages : en
Pages : 126

Book Description
The work of creating a fully habitable life with a past and present preoccupies Sonja Greckol. In Gravity Matters, she traces an arc: from a nineteenth-century European family that immigrated and settled in central Alberta to a digitized wondering held together by Skype and Google rooted in central Toronto. In this, a first collection, Greckol turns obliquely from the matters of largely personal lyrics to historical and international preoccupations that, nevertheless, remain embodied--a pentimento of certainties, sensualities and queries, empiricism and theory in science, moving from daughter to mother and then mother/daughtering once again--in a feminist voice that is urgent, empathic and wry. Her long poem, Emilie Explains Newton to Voltaire, a fractured sonetto magistrale voices a eighteenth-century physicist and noble woman, Emilie du Châtelet, a key figure of the Enlightenment and locates her in mind and body ands well as in her time. This poem was short-listed for the CBC Poetry Prize in 2008.

Gravity of the Matter

Gravity of the Matter PDF Author: Mark F. Dennis
Publisher: Createspace Independent Pub
ISBN: 9781500409722
Category : Science
Languages : en
Pages : 248

Book Description
It is in understanding the Gravity of the Matter that surrounds us, that we may possibly someday soon lose the hold that gravity has on us; being able to move across space untethered and unchained by its grasp. Transport to far distant stars and planets in other galaxies may soon be realized. We are living in the early twenty-first century, almost 100 years after Einstein's theories were developed. These theories became the foundation of quantum mechanics and modern theoretical physics that is taught in our schools today. Is it not time to begin questioning these old theories again? As Albert Einstein himself said:“To deny the aether is ultimately to assume that empty space has no physical qualities whatever. The fundamental facts of mechanics do not harmonize with this view…"

Cosmic Creation and Evolution of Matter, Energy, and Gravity

Cosmic Creation and Evolution of Matter, Energy, and Gravity PDF Author: James Carter
Publisher: Lulu.com
ISBN: 0359804578
Category : Science
Languages : en
Pages : 158

Book Description
This book examines the experimental measurements that are used to verify Einstein's theories of special and general relativity and his ideas about relativistic cosmology that eventually became the Big Bang. It examines the differences between the calculations of Einstein's metaphysical assumptions and the physical principles of the Living Cosmos. The Living Cosmos makes the same astronomical measurements as relativity but does so from perspectives that are upside down, backwards, and inside out from standard model Big Bang theories. The book presents new principles for atomic physics and gravity based on the physical measurements of mass, space, time, and gravity instead of relativity's metaphysical assumptions of equivalent force and "pure" photon energy. The creation of the Living Cosmos is revealed as a sequential, non-synchronous, evolutionary process in which the galaxies were created first, then the stars, and finally our atomic matter. The true and absolute nature of gravity experiments is revealed.

Gravity's Time

Gravity's Time PDF Author: C. S. Unnikrishnan
Publisher: CRC Press
ISBN: 1000522768
Category : Science
Languages : en
Pages : 314

Book Description
This book is unique and exceptional in dealing with the notion of physical time rigorously, both logically and empirically. The central theme is the intimate relation between physical time and cosmic gravity. It establishes and explains, in an accessible manner, the one crucial physical fact that has been missed in the development of modern physics—that the enormous gravity of the matter and energy in the Universe is the controller and cause of the relativistic time. The material in the book is accurate and free of the ambiguities in the discussion of time and its modifications (dilation), synchronization of clocks, and simultaneity. The contents go beyond the current theories of relativity that fail to incorporate the cosmic gravity in their structure. The discussion of clocks in satellite navigational systems (like the GPS) is the most complete and accurate. The book offers several new insights, and it is the only available treatise on the complete physical truth about time. The contents are addressed to a wide range of readers, from general readers and students to experienced researchers, and will also appeal well to philosophers and historians of physics. This book has the enabling quality to deal with difficult questions about physical time, with unprecedented clarity and without paradoxes.

Asymptotically Safe Gravity

Asymptotically Safe Gravity PDF Author: Alessia Benedetta Platania
Publisher: Springer
ISBN: 3319987941
Category : Science
Languages : en
Pages : 142

Book Description
This book seeks to construct a consistent fundamental quantum theory of gravity, which is often considered one of the most challenging open problems in present-day physics. It approaches this challenge using modern functional renormalization group techniques, and attempts to realize the idea of “Asymptotic Safety” originally proposed by S. Weinberg. Quite remarkably, the book makes significant progress regarding both the fundamental aspects of the program and its phenomenological consequences. The conceptual developments pioneer the construction of a well-behaved functional renormalization group equation adapted to spacetimes with a preferred time-direction. It is demonstrated that the Asymptotic Safety mechanism persists in this setting and extends to many phenomenologically interesting gravity-matter systems. These achievements constitute groundbreaking steps towards bridging the gap between quantum gravity in Euclidean and Lorentzian spacetimes.The phenomenological applications cover core topics in quantum gravity, e.g. constructing a phenomenologically viable cosmological evolution based on quantum gravity effects in the very early universe, and analyzing quantum corrections to black holes forming from a spherical collapse.As a key feature, all developments are presented in a comprehensive and accessible way. This makes the work a timely and valuable guide into the rapidly evolving field of Asymptotic Safety.

Nonlocal Gravity

Nonlocal Gravity PDF Author: Bahram Mashhoon
Publisher: Oxford University Press
ISBN: 0192525956
Category : Science
Languages : en
Pages : 249

Book Description
Relativity theory is based on a postulate of locality, which means that the past history of the observer is not directly taken into account. This book argues that the past history should be taken into account. In this way, nonlocality—-in the sense of history dependence—-is introduced into relativity theory. The deep connection between inertia and gravitation suggests that gravity could be nonlocal, and in nonlocal gravity the fading gravitational memory of past events must then be taken into account. Along this line of thought, a classical nonlocal generalization of Einstein's theory of gravitation has recently been developed. A significant consequence of this theory is that the nonlocal aspect of gravity appears to simulate dark matter. According to nonlocal gravity theory, what astronomers attribute to dark matter should instead be due to the nonlocality of gravitation. Nonlocality dominates on the scale of galaxies and beyond. Memory fades with time; therefore, the nonlocal aspect of gravity becomes weaker as the universe expands. The implications of nonlocal gravity are explored in this book for gravitational lensing, gravitational radiation, the gravitational physics of the Solar System and the internal dynamics of nearby galaxies, as well as clusters of galaxies. This approach is extended to nonlocal Newtonian cosmology, where the attraction of gravity fades with the expansion of the universe. Thus far, scientists have only compared some of the consequences of nonlocal gravity with astronomical observations.

Pages : 127

Book Description
Gravity is the most detectable physical phenomenon of the universe. Nothing or nobody can escape its grasp, even in very large, astronomical distances. It is manifested in many aspects of our lives. Yet we are still not really sure what carries it. The gradually increasing understanding of gravity throughout history and its observed effects in various physical fields are the subjects of this book. This is an enlightening read about one of the most misterious phenomena of our lives that is still far from being fully understood, presenting a historical journey through several millennia of encountering and understanding gravitys mysteries.
