Conversations on Quantum Gravity - - Bog - Cambridge University Press - Plusbog.dk

Conversations on Quantum Gravity - - Bog - Cambridge University Press - Plusbog.dk

The holy grail of theoretical physics is to find the theory of everything that combines all the forces of nature, including gravity. This book addresses the question: how far are we from such discovery? Over the last few decades, multiple roads to finding a quantum theory of gravity have been proposed but no obvious description of nature has emerged in this domain. What is to be made of this situation? This volume probes the state-of-the art in this daunting quest of theoretical physics by collecting critical interviews with nearly forty leading theorists in this field. These broad-ranging conversations give important insights and candid opinions on the various approaches to quantum gravity, including string theory, loop quantum gravity, causal set theory and asymptotic safety. This unique, readable overview provides a gateway into cutting edge research for students and others who wish to engage with the open problem of quantum gravity.

What Goes Up... Gravity and Scientific Method - Peter (northern Arizona University) Kosso - Bog - Cambridge University Press - Plusbog.dk

What Goes Up... Gravity and Scientific Method - Peter (northern Arizona University) Kosso - Bog - Cambridge University Press - Plusbog.dk

The concept of gravity provides a natural phenomenon that is simultaneously obvious and obscure; we all know what it is, but rarely question why it is. The simple observation that ''what goes up must come down'' contrasts starkly with our current scientific explanation of gravity, which involves challenging and sometimes counterintuitive concepts. With such extremes between the plain and the perplexing, gravity forces a sharp focus on scientific method. Following the history of gravity from Aristotle to Einstein, this clear account highlights the logic of scientific method for non-specialists. Successive theories of gravity and the evidence for each are presented clearly and rationally, focusing on the fundamental ideas behind them. Using only high-school level algebra and geometry, the author emphasizes what the equations mean rather than how they are derived, making this accessible for all those curious about gravity and how science really works.

The Motion of Bubbles and Drops in Reduced Gravity - R.shankar Subramanian - Bog - Cambridge University Press - Plusbog.dk

The Motion of Bubbles and Drops in Reduced Gravity - R.shankar Subramanian - Bog - Cambridge University Press - Plusbog.dk

Orbiting spacecraft provide a valuable laboratory for experiments on physical and biological systems in a reduced gravity environment. In these studies, fluid masses containing bubbles and drops are encountered routinely. This 2001 book provides a clear, thorough review of the motion of bubbles and drops in reduced gravity. The emphasis is on theoretical analysis from first principles.

Covariant Loop Quantum Gravity - Francesca Vidotto - Bog - Cambridge University Press - Plusbog.dk

Covariant Loop Quantum Gravity - Francesca Vidotto - Bog - Cambridge University Press - Plusbog.dk

Quantum gravity is among the most fascinating problems in physics. It modifies our understanding of time, space and matter. The recent development of the loop approach has allowed us to explore domains ranging from black hole thermodynamics to the early Universe. This book provides readers with a simple introduction to loop quantum gravity, centred on its covariant approach. It focuses on the physical and conceptual aspects of the problem and includes the background material needed to enter this lively domain of research, making it ideal for researchers and graduate students. Topics covered include quanta of space; classical and quantum physics without time; tetrad formalism; Holst action; lattice QCD; Regge calculus; ADM and Ashtekar variables; Ponzano-Regge and Turaev-Viro amplitudes; kinematics and dynamics of 4D Lorentzian quantum gravity; spectrum of area and volume; coherent states; classical limit; matter couplings; graviton propagator; spinfoam cosmology and black hole thermodynamics.

Acquisition and Analysis of Terrestrial Gravity Data - Leland Timothy Long - Bog - Cambridge University Press - Plusbog.dk

Acquisition and Analysis of Terrestrial Gravity Data - Leland Timothy Long - Bog - Cambridge University Press - Plusbog.dk

Gravity surveys have a huge range of applications, indicating density variations in the subsurface and identifying man-made structures, local changes of rock type or even deep-seated structures at the crust/mantle boundary. This important one-stop book combines an introductory manual of practical procedures with a full explanation of analysis techniques, enabling students, geophysicists, geologists and engineers to understand the methodology, applications and limitations of a gravity survey. Filled with examples from a wide variety of acquisition problems, the book instructs students in avoiding common mistakes and misconceptions. It explores the increasing near-surface geophysical applications being opened up by improvements in instrumentation and provides more advance-level material as a useful introduction to potential theory. This is a key text for graduate students of geophysics and for professionals using gravity surveys, from civil engineers and archaeologists to oil and mineral prospectors and geophysicists seeking to learn more about the Earth''s deep interior.

The Irresistible Attraction of Gravity - Luciano (goethe Universitat Frankfurt Am Main) Rezzolla - Bog - Cambridge University Press - Plusbog.dk

The Irresistible Attraction of Gravity - Luciano (goethe Universitat Frankfurt Am Main) Rezzolla - Bog - Cambridge University Press - Plusbog.dk

The mystery of gravity has captivated us for centuries. But what is gravity and how does it work? This engaging book delves into the bizarre and often counter-intuitive world of gravitational physics. Join distinguished astrophysicist Professor Luciano Rezzolla on this virtual journey into Einstein''s world of gravity, with each milestone presenting ever more fascinating aspects of gravitation. Through gentle exposure to concepts such as spacetime curvature and general relativity, you will discover some of the most curious consequences of gravitational physics, such as black holes, neutron stars and gravitational waves. The author presents and explains one of the most impressive scientific achievements of recent times: the first image of a supermassive black hole. Written by one of the key scientists involved in producing these results, you''ll get a behind-the-scenes view of how the image was captured and discover what happens to matter and light near a black hole.
