Book Description
"Magnifying Spacetime delivers new insights into the role of scale in quantum gravity from the cutting-edge of modern research using an accessible and pedagogical style. The ideal complementary text for undergraduate and graduate students, this book also serves as an essential resource for professional physicists working on related topics. However, the scientifically literate layman should also find this work accessible due to the emphasis on conceptual understanding. Daniel Coumbe takes readers on a journey from the basics of scale transformations to the frontiers of quantum gravity research, including fractal geometry, minimum length scenarios, the renormalization group, Weinberg's asymptotic safety scenario, causal dynamical triangulations, spontaneous dimensional reduction, and Weyl's modification of Einstein's general relativity"--

Book Description
The 1996 NATO Advanced Study Institute (ASI) followed the international tradi tion of the schools held in Cargese in 1976, 1979, 1983, 1987 and 1991. Impressive progress in quantum field theory had been made since the last school in 1991. Much of it is connected with the interplay of quantum theory and the structure of space time, including canonical gravity, black holes, string theory, application of noncommutative differential geometry, and quantum symmetries. In addition there had recently been important advances in quantum field theory which exploited the electromagnetic duality in certain supersymmetric gauge theories. The school reviewed these developments. Lectures were included to explain how the "monopole equations" of Seiberg and Witten can be exploited. They were presented by E. Rabinovici, and supplemented by an extra 2 hours of lectures by A. Bilal. Both the N = 1 and N = 2 supersymmetric Yang Mills theory and resulting equivalences between field theories with different gauge group were discussed in detail. There are several roads to quantum space time and a unification of quantum theory and gravity. There is increasing evidence that canonical gravity might be a consistent theory after all when treated in. a nonperturbative fashion. H. Nicolai presented a series of introductory lectures. He dealt in detail with an integrable model which is obtained by dimensional reduction in the presence of a symmetry.

Book Description
In June 2021, the U.S. National Intelligence publicly admitted that UFOs are real physical objects and that they have been penetrating restricted military airspace since at least 2004. Despite this bombshell and further recent admissions by the Pentagon, the identity of these mysterious craft remains unknown. This book brings the full scientific method to bear on this enigmatic issue. Written by Daniel Coumbe, a former research scientist at the Niels Bohr Institute in Copenhagen with a PhD in theoretical particle physics, this book defines one of the first scientifically credible studies of UFOs in the modern era. Anomaly reveals new results derived from radar, optical sensors, and scientific instruments, rather than speculating on unreliable eyewitness testimony. This scientific approach provides the reader with clear and reliable answers, something that is desperately needed in the murky field of UFOs.

Book Description
This is the first detailed account of a new approach to microphysics based on two leading ideas: (i) the explicit dependence of physical laws on scale encountered in quantum physics, is the manifestation of a fundamental principle of nature, scale relativity. This generalizes Einstein's principle of (motion) relativity to scale transformations; (ii) the mathematical achievement of this principle needs the introduction of a nondifferentiable space-time varying with resolution, i.e. characterized by its fractal properties.The author discusses in detail reactualization of the principle of relativity and its application to scale transformations, physical laws which are explicitly scale dependent, and fractals as a new geometric description of space-time.

Book Description
NATIONAL BESTSELLER • From one of the world’s leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes “an astonishing ride” through the universe (The New York Times) that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

Book Description
Guiding us through Einstein's theory of relativity, quantum mechanics, and string theory, Astronomical explains the baffling mysteries of the cosmos: from alien life to the zodiac; from white holes to wormholes; from quasars to quark stars—all within a narrative that is as entertaining as it is edifying. Does the Big Bang prove the existence of God? What's the Universe expanding into? Is Earth the only planet which supports life? Space is the biggest, oldest, hottest, coldest, strangest thing a human can study. It's no surprise then, that the weirdest facts in science (not to mention the weirdest scientists themselves) are found in astrophysics and cosmology. If you're looking for instructions on how to set up your grandad's telescope this book probably isn't for you. In Astronomical, Tim James takes us on a tour of the known (and unknown) universe, focusing on the most-mind boggling stuff we've come across, as well as unpacking the latest theories about what's really going on out there. Guiding us through Einstein's relativity, quantum mechanics and string theory, Astronomical delves into the baffling corners of the cosmos and tackles the biggest mysteries we face: from alien life to the zodiac; from white holes to wormholes; from quasars to quark stars. This is the science of space at its absolute strangest.

Book Description
This introductory textbook on the general theory of relativity presents a solid foundation for those who want to learn about relativity. The subject is presented in a physically intuitive, but mathematically rigorous style. The topic of relativity is covered in a broad and deep manner. Besides, the aim is that after reading the book a student should not feel discouraged when she opens advanced texts on general relativity for further reading. The book consists of three parts: An introduction to the general theory of relativity. Geometrical mathematical background material. Topics that include the action principle, weak gravitational fields and gravitational waves, Schwarzschild and Kerr solution, and the Friedman equation in cosmology. The book is suitable for advanced graduates and graduates, but also for established researchers wishing to be educated about the field.
