This book was released on 2002-04-30 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this XVII Course of the International School of Cosmology and Gravitation devoted to "ADVANCES IN THE INTERPLAY BETWEEN QUANTUM AND GRAVITY PHYSICS" we have considered different aspects of the influence of gravity on quantum systems. In order to achieve this aim, in many lectures, seminars and discussions we have strengthened the interplay between gravity and quantum systems starting from the situation in the early universe based on astrophysical observations, up to the earthly based experiments with atom interferometry for probing the structure of space-time. Thus we have had timely lectures on the quantum field and horizon of a black hole including reviews of the problem of black holes thermodynamics and entropy, quantum information, quantum black holes, quantum evaporation and Hawking radiation, recent advances in stockastic gravity. We have also discussed quantum fluctuations in inflationary universe, quantum effects and reheating after inflation, and superplanckian energies in Hawking radiation. In this regard the subject of spinors in purely affine space-time and Dirac matter according to Weyl in the generalized theory of gravitation were developed . The dualism between space-time and matter has been deeply analyzed in order to see why, for general relativity, this is an obstacle for quantization of the theory. Also canonical Gravity and Mach's principle, torsion and curvature as commutator for Quantum Gravity and Dirac Geometry of real space-time were analysed, together with the problem of 5-Dimensional Projective Unified Field theory and Multidimensional Gravity and Cosmology.

Download or read book A Question of Gravity and Light written by Blas Falconer and published by University of Arizona Press. This book was released on 2007 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is rare to find contemporary American poetry that speaks to readers with engaging directness, free of pretense or posturing. That is exactly the kind of poetry that Blas Falconer writes. In his first collection, Falconer presents 46 poems that are emotionally forthright and linguistically evocative but written without affectation or subterfuge. Although Falconer is formally trained and is aware of the structures and potential of both free verse and traditional poetic forms, he crafts exquisite, heartfelt poems that surprise us with their simple intensity. Whether writing about the mysteries of childhood or the pleasures of cruising for gay sex in a metropolitan airport, he surprises us with the delicacy of his touch, never obvious or heavy-handed. As a gay man who embraces his Puerto Rican heritage, Falconer stands at an edge of American society, and there is the tension of borders in his work: borders between peoples and nations as well as the less visible, more porous and deceptive borders between family members and lovers. There is not one point of view in these poems but many. It is the quality of their observational power that binds them together. Whether the setting is the hospital room of his dying grandfather or his own backyard teeming with garrulous tree frogs, Falconer transports us to the scene. It is easy for us to imagine what he sees. And we care, deeply, just as he does.

Download or read book Progress and Visions in Quantum Theory in View of Gravity written by Felix Finster and published by Springer Nature. This book was released on 2020-04-09 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on a critical discussion of the status and prospects of current approaches in quantum mechanics and quantum field theory, in particular concerning gravity. It contains a carefully selected cross-section of lectures and discussions at the seventh conference “Progress and Visions in Quantum Theory in View of Gravity” which took place in fall 2018 at the Max Planck Institute for Mathematics in the Sciences in Leipzig. In contrast to usual proceeding volumes, instead of reporting on the most recent technical results, contributors were asked to discuss visions and new ideas in foundational physics, in particular concerning foundations of quantum field theory. A special focus has been put on the question of which physical principles of quantum (field) theory can be considered fundamental in view of gravity. The book is mainly addressed to mathematicians and physicists who are interested in fundamental questions of mathematical physics. It allows the reader to obtain a broad and up-to-date overview of a fascinating active research area.

Download or read book Modified and Quantum Gravity written by Christian Pfeifer and published by Springer Nature. This book was released on 2023-11-01 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses theoretical predictions and their comparison with experiments of extended and modified classical and quantum theories of gravity. The goal is to provide a readable access and broad overview over different approaches to the topic to graduate and PhD students as well as to young researchers. The book presents both, theoretical and experimental insights and is structured in three parts. The first addresses the theoretical models beyond special and general relativity such as string theory, Poincare gauge theory and teleparallelism as well as Finsler gravity. In turn, the second part is focused on the observational effects that these models generate, accounting for tests and comparisons which can be made on all possible scales: from the universe as a whole via binary systems, stars, black holes, satellite experiments, down to laboratory experiments at micrometer and smaller scales. The last part of this book is dedicated to quantum systems and gravity, showing tests of classical gravity with quantum systems, and coupling of quantum matter and gravity.

Download or read book Gravity s Century written by Ron Cowen and published by Harvard University Press. This book was released on 2019-05-06 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: “This gracefully written history of twentieth-century gravity research” brings to life the discoveries and developments that confirmed the theory of relativity (Publishers Weekly, starred review). Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time. A century later, the Event Horizon Telescope examined the space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way, to determine whether Einstein was right on the details. In Gravity’s Century, award-winning science writer Ron Cowen brings to life the incredible scientific journey between these two events and sheds light on their groundbreaking implications. From the development of radio telescopes to the discovery of black holes and quasars, and the still-unresolved place of gravity in quantum theory, Cowen breaks down the physics in clear and approachable language. Gravity’s Century vividly demonstrates how the quest to understand gravity is really the quest to comprehend the universe./

Download or read book Mission Of Gravity written by Hal Clement and published by Hachette UK. This book was released on 2014-12-11 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesklin is a vast, inhospitable, disc-shaped planet, so cold that its oceans are liquid methane and its snows are frozen ammonia. It is a world spinning dizzyingly, a world where gravity can be a crushing 700 times greater than Earth's, a world too hostile for human explorers. But the planet holds secrets of inestimable value, and an unmanned probe that has crashed close to one of its poles must be recovered. Only the Mesklinites, the small creatures so bizarrely adapted to their harsh environment, can help. And so Barlennan, the resourceful and courageous captain of the Mesklinite ship Bree, sets out on an heroic and appalling journey into the terrible unknown. For him and his people, the prize to be gained is as great as that for mankind... Hal Clement's MISSION OF GRAVITY is universally regarded as one of the most important and best loved novels in the genre. The remarkable and sympathetic depiction of an alien species and the plausible and scientifically based realisation of the strange world they inhabit make it a major landmark in the history of hard SF.

Download or read book Matters of Gravity written by Scott Bukatman and published by Duke University Press. This book was released on 2003-07-21 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Euclidean Quantum Gravity written by G. W. Gibbons and published by World Scientific. This book was released on 1993 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Euclidean approach to Quantum Gravity was initiated almost 15 years ago in an attempt to understand the difficulties raised by the spacetime singularities of classical general relativity which arise in the gravitational collapse of stars to form black holes and the entire universe in the Big Bang. An important motivation was to develop an approach capable of dealing with the nonlinear, non-perturbative aspects of quantum gravity due to topologically non-trivial spacetimes. There are important links with a Riemannian geometry. Since its inception the theory has been applied to a number of important physical problems including the thermodynamic properties of black holes, quantum cosmology and the problem of the cosmological constant. It is currently at the centre of a great deal of interest.This is a collection of survey lectures and reprints of some important lectures on the Euclidean approach to quantum gravity in which one expresses the Feynman path integral as a sum over Riemannian metrics. As well as papers on the basic formalism there are sections on Black Holes, Quantum Cosmology, Wormholes and Gravitational Instantons.

Download or read book Asymptotically Safe Gravity written by Alessia Benedetta Platania and published by Springer. This book was released on 2018-09-20 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
