This book is intended to give an updated overview on the state-of-the art of the theoretical and experimental efforts aimed to detect the elusive Lense-Thirring effect in the gravitational field of the Earth. The reader, after a robust introduction to the historical (Chapter 2) and theoretical (Chapters 3-5) aspects of the subject, will get acquainted with the subtleties required to design suitable observables which are able to sufficiently enhance the signal-to-noise ratio. Moreover, he/she should be able to follow autonomously the exciting developments which, hopefully, will take place in the near future if and when reliable few percent tests of this prediction of general relativity should become available. In an Earth-space based experiment with artificial satellites a good compromise between the need of reducing the impact of the systematic errors of gravitational origin and of non-gravitational origin must be obtained; this is not an easy task because such requirements are often in conflict one with each other. Consequently, a great attention is paid to elucidate many classical perturbing effects which, if not carefully modelled and accounted for in the data analysis, may alias the recovery of the gravitomagnetic signature. Indeed, we are dealing with a fundamental test of general relativity which must be honest, robust and based on solid error analysis. A critical and detailed discussion of the latest test with the LAGEOS satellites is included. The book will also be useful for better understanding the interplay among various geodetic, geophysical, general relativistic, astronomical and matter-wave interferometric effects which occurs in the weak-field and slow-motion approximation and which will become increasingly important in the near future thanks to the improvements in the accuracy of the orbital reconstruction process.

Gravity is the weakest of the natural forces and yet it dominates our lives. We know how to make use of its properties and how to overcome it. But we can’t control it. To do that we must be able to generate and control gravity’s hidden companion force field, called gravitomagnetism. Mass is the source of gravity fields.

This book invites the reader to understand our Universe, not just marvel at it. From the clock-like motions of the planets to the catastrophic collapse of a star into a black hole, gravity controls the Universe. Gravity is central to modern physics, helping to answer the deepest questions about the nature of time, the origin of the Universe and the unification of the forces of nature. Linking key experiments and observations through careful physical reasoning, the author builds the reader's insight step-by-step from simple but profound facts about gravity on Earth to the frontiers of research. Topics covered include the nature of stars and galaxies, the mysteries of dark matter and dark energy, black holes, gravitational waves, inflation and the Big Bang. Suitable for general readers and for undergraduate courses, the treatment uses only high-school level mathematics, supplemented by optional computer programs, to explain the laws of physics governing gravity.

Many new tests of gravity and, in particular, of Einstein's general relativity theory will be carried out in the near future: The Lense--Thirring effect and the equivalence principle will be tested in space; moreover, gravitational waves will be detected, and new atomic interferometers and clocks will be built for measurements in gravitational and inertial fields. New high-precision devices have made these experiments feasible. They will contribute to a better understanding of gravitational physics. Both experimental developments and the theoretical concepts are collected in this volume. Exhaustive reviews give an overall insight into the subject of experimental gravitation.

This book gives a detailed, up-to-date account of theLenseOCoThirring effect and its implications for physics andastrophysics. Starting from a profound intuition of Lense and Thirringin 1918, based on a simple solution to the linearized Einstein fieldequations, this has emerged in the past four decades as a phenomenonof extraordinary importance in cosmology, radio jets in quasars, andthe physics of neutron stars and black holes, besides leading to someof the most sophisticated experiments ever performed in the spacesurrounding our planet."

This book describes an exciting, but unfinished scientific adventure story. It tells of the epic struggle by scientists to wrest the secrets from nature of how to control the force of electromagnetism and how to control aerodynamic forces. Control of the force of gravity has yet to be achieved. Analogies suggest where a breakthrough might be made. Greenglow & the search for gravity control follows the attempts mankind has made over the years to understand gravity as well as looking at more recent experiments to control it. The book is written by an engineer, who worked in the aerospace industry, and who persuaded BAE Systems to sponsor Project Greenglow, a small research programme aimed at investigating some ideas for controlling gravity. Based on analogies in nature, the book provides a road map for scientists, engineers and the general public who want to know more about gravity and our search to control it. Discovering nature’s secrets is an exciting, but unfinished story – there is much we still don’t know. The book describes the quest by scientists to gain control of gravity and electromagnetism, the two long-range forces of nature. Faraday discovered the secret of electromagnetic control. Newton began the search for gravity control, later continued by Einstein, but it eluded them. One day the secret will be discovered either by careful experimentation or, as is often the case, by stumbling across it by chance. In the future it is expected that gravity control will underpin a new method of propulsion and this book concludes with a look at some possible forms. Greenglow is a fascinating read for any aerospace engineers, physicists, experimental research scientists, science journalists, science historians, futurologists, UFO enthusiasts, Star Trekkies and general public interested in the breakthrough in understanding of how to control gravity.

Einstein's standard and battle-tested geometric theory of gravity--spacetime tells mass how to move and mass tells spacetime how to curve--is expounded in this book by Ignazio Ciufolini and John Wheeler. They give special attention to the theory's observational checks and to two of its consequences: the predicted existence of gravitomagnetism and the origin of inertia (local inertial frames) in Einstein's general relativity: inertia here arises from mass there. The authors explain the modern understanding of the link between gravitation and inertia in Einstein's theory, from the origin of inertia in some cosmological models of the universe, to the interpretation of the initial value formulation of Einstein's standard geometrodynamics; and from the devices and the methods used to determine the local inertial frames of reference, to the experiments used to detect and measure the "dragging of inertial frames of reference." In this book, Ciufolini and Wheeler emphasize present, past, and proposed tests of gravitational interaction, metric theories, and general relativity. They describe the numerous confirmations of the foundations of geometrodynamics and some proposed experiments, including space missions, to test some of its fundamental predictions--in particular gravitomagnetic field or "dragging of inertial frames" and gravitational waves.

In early April 1911 Albert Einstein arrived in Prague to become full professor of theoretical physics at the German part of Charles University. It was there, for the first time, that he concentrated primarily on the problem of gravitation. Before he left Prague in July 1912 he had submitted the paper “Relativität und Gravitation: Erwiderung auf eine Bemerkung von M. Abraham” in which he remarkably anticipated what a future theory of gravity should look like. At the occasion of the Einstein-in-Prague centenary an international meeting was organized under a title inspired by Einstein's last paper from the Prague period: "Relativity and Gravitation, 100 Years after Einstein in Prague". The main topics of the conference included: classical relativity, numerical relativity, relativistic astrophysics and cosmology, quantum gravity, experimental aspects of gravitation and conceptual and historical issues. The conference attracted over 200 scientists from 31 countries, among them a number of leading experts in the field of general relativity and its applications. This volume includes abstracts of the plenary talks and full texts of contributed talks and articles based on the posters presented at the conference. These describe primarily original results of the authors. Full texts of the plenary talks are included in the volume "General Relativity, Cosmology and Astrophysics--Perspectives 100 Years after Einstein in Prague", eds. J. Bičák and T. Ledvinka, published also by Springer Verlag.
