This book presents an overview of the current understanding of gravitation, with a focus on the current efforts to test its theory, especially general relativity. It shows how the quest for a deeper theory, which would possibly incorporate gravity in the quantum realm, is more than ever an open field. The majority of the contributions deals with the manifold facets of “experimental gravitation”, but the book goes beyond this and covers a broad range of subjects from the foundations of gravitational theories to astrophysics and cosmology. The book is divided into three parts. The first part deals with foundations and Solar System tests. An introductory pedagogical chapter reviews first Newtonian gravitational theory, special relativity, the equivalence principle and the basics of general relativity. Then it focuses on approximation methods, mainly the post-Newtonian formalism and the relaxed Einstein equations, with a discussion on how they are used in treating experimental tests and in the problem of generation and detection of gravitational waves. Following this is a set of chapters describing the most recent experiments, techniques and observations on the testing of gravity theories in the laboratory, around the Earth and in the Solar System. The second part is dedicated to astrophysical topics deeply linked with the study of gravitation, namely binary pulsars and the perspective of direct detection of gravitational waves. These cases are paradigmatic in that the gravitational signals act at the same time as messengers helping us to understand the properties of important and wide classes of astrophysical objects. The third part explores the many open issues in current knowledge of gravitation machinery, especially related to astrophysical and cosmological problems and the way possible solutions to them impact the quest for a quantum theory of gravitation and unified theory. Included is a selection of the many possible paths, giving a hint to the subtleties one is called upon. Whenever possible, a close link to observational constraints and possible experimental tests is provided. In selecting the topics of the various contributions, particular care has been devoted to ensure their fit in a coherent representation of our understanding of gravitational phenomena. The book is aimed at graduate level students and will form a valuable reference for those working in the field.

"Humans will eradicate themselves long before the universe gets around to it." -The Tesseract It's today's world. Humans are in charge of themselves. Science coexists with alt-facts. Politics mingles with anti-government movements. Religion dances with skeptics. Yes, it's a typical year in the span of man. So what could go wrong with man's usual conflict and blind progress? Nothing . . . until it all unravels in the blink of an eye. Welcome to tomorrow's bizarre world of gravitational death, the destructive evolution of man, and random acts of courage. First Contact: The Reluctant Prophet A preacher in rural Georgia awakes one Sunday morning with a vivid prediction that millions would soon die. He feels compelled to share his profound revelation with his congregation. But his wife is unconvinced, blaming his nightmare visions on bedside bourbon. She threatens to ban alcohol from the house. Second Contact: The Early Victims Career politicians and other repeat offenders die by the thousands when they are repulsed from Earth by terrifying reversals of gravity. Third Contact: The Non-Hero An injured bicycle messenger in San Francisco learns to control his own gravity. People call him Jesus Part 2, but he has more noble plans than just pretending to be the next savior.

The search for a quantum theory of the gravitational field is one of the great open problems in theoretical physics. This book presents a self-contained discussion of the concepts, methods and applications that can be expected in such a theory. The two main approaches to its construction -- the direct quantisation of Einstein's general theory of relativity and string theory -- are covered. Whereas the first attempts to construct a viable theory for the gravitational field alone,string theory assumes that a quantum theory of gravity will be achieved only through a unification of all the interactions. However, both employ the general method of quantization of constrained systems, which is described together with illustrative examples relevant for quantum gravity. There is adetailed presentation of the main approaches employed in quantum general relativity: path-integral quantization, the background-field method and canonical quantum gravity in the metric, connection and loop formulations. The discussion of string theory centres around its quantum-gravitational aspects and the comparison with quantum general relativity. Physical applications discussed at length include the quantization of black holes, quantum cosmology, the indications of a discrete structure ofspacetime, and the origin of irreversibility.The second edition will add some sections on topical issues. These include loop quantum cosmology, dynamical triangulation, renormalization-group approach, primordial black holes, and information-loss problem for black holes. The second edition will also contain some pedagogical extensions.This book will be of interest to researchers and students working in relativity and gravitation, cosmology, quantum field theory and related topics. It will also be of interest to mathematicians and philosophers of science.

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.

A thrilling debut packed with action and mystery. Aliens never looked so good." –Jennifer L. Armentrout, #1 NYT bestselling author In the future, only one rule will matter: Don't. Ever. Peek. Seventeen-year-old Ari Alexander just broke that rule and saw the last person she expected hovering above her bed — arrogant Jackson Locke, the most popular boy in her school. She expects instant execution or some kind of freak alien punishment, but instead, Jackson issues a challenge: help him, or everyone on Earth will die. Ari knows she should report him, but everything about Jackson makes her question what she's been taught about his kind. And against her instincts, she's falling for him. But Ari isn't just any girl, and Jackson wants more than her attention. She's a military legacy who's been trained by her father and exposed to war strategies and societal information no one can know — especially an alien spy, like Jackson. Giving Jackson the information he needs will betray her father and her country, but keeping silent will start a war. The Taking series is best enjoyed in order.

1946 is the year Bryce DeWitt entered Harvard graduate school. Quantum Gravity was his goal and remained his goal throughout his lifetime until the very end. The pursuit of Quantum Gravity requires a profound understanding of Quantum Physics and Gravitation Physics. As G. A. Vilkovisky commented , "Quantum Gravity is a combination of two words, and one should know both. Bryce understood this as nobody else, and this wisdom is completely unknown to many authors of the flux of papers that we see nowadays." Distingished physicist Cecile DeWitt-Morette skillfully blends her personal and scientific account with a wealth of her late husband's often unpublished writings on the subject matter. This volume, through the perspective of the leading researcher on quantum gravity of his generation, will provide an invaluable source of reference for anyone working in the field.

In recognizing that new teachers often feel disempowered by the subject expertise they bring into teaching, this book not only covers the training standards for NQTs and the Induction Standards, but takes the reader beyond this by fully exploring issues relating to subject knowledge in learning to teach. Divided into three sections the book covers: framing the subject - defining subject knowledge and focusing on questions about science as a school subject teaching the subject - looking at pedagogical, curricular and pupil knowledge science within the professional community - focusing on the place of science within the wider curriculum and the teaching community. This refreshing new book provides stimulating assistance to subject specialists, from new teachers of science in the early years of professional development to those on a PGCE course or in their induction year. It is also suitable for subject leaders with mentor responsibilities and Advanced Skills Teachers undertaking specialist inset and teaching support.

Gravity and Grace was the first ever publication by the remarkable thinker and activist, Simone Weil. In it Gustave Thibon, the farmer to whom she had entrusted her notebooks before her untimely death, compiled in one remarkable volume a compendium of her writings that have become a source of spiritual guidance and wisdom for countless individuals. On the fiftieth anniversary of the first English edition - by Routledge & Kegan Paul in 1952 - this Routledge Classics edition offers English readers the complete text of this landmark work for the first time ever, by incorporating a specially commissioned translation of the controversial chapter on Israel. Also previously untranslated is Gustave Thibon's postscript of 1990, which reminds us how privileged we are to be able to read a work which offers each reader such 'light for the spirit and nourishment for the soul'. This is a book that no one with a serious interest in the spiritual life can afford to be without.

Being-in-time to the music from the ground up is a work in phenomenology, where this term is broadly defined, comprehending Plato, Heidegger, Hegel, and Marx. The most direct referent is Hegel, together with the theoretical revolution that he initiated with Phenomenology of Mind. This text's more general purpose is to set the tone for a 21st communism based upon the idea of dancing with death, assuming full responsibility for one's mortality, and abandoning the self to love as the meaning of existence.This dance is choreographed through my conversations with the above mentioned writers. In conversing with them I aim to displace (if not usurp) them from the throne of honour which is nothing more than the authority borrowed from me. By this I do not intend to deny completely their 'other to me' character.However, they exist or even 'figure' for me, both in the sense of of 'count,' having importance, as those that I read, and by which I read myself. They have borrowed my authority, namely, my own potential to be an author. So 'reading them is to re-assume that borrowed authority. The life of the reader, to paraphrase Barthes, begins with the death of the author.
