Book Description
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.

Book Description
Why the force that keeps our feet on the ground holds the key to understanding the nature of time and the origin of the universe. Gravity is the weakest force in the everyday world yet it is the strongest force in the universe. It was the first force to be recognized and described yet it is the least understood. It is a "force" that keeps your feet on the ground yet no such force actually exists. Gravity, to steal the words of Winston Churchill, is "a riddle, wrapped in a mystery, inside an enigma." And penetrating that enigma promises to answer the biggest questions in science: what is space? What is time? What is the universe? And where did it all come from? Award-winning writer Marcus Chown takes us on an unforgettable journey from the recognition of the "force" of gravity in 1666 to the discovery of gravitational waves in 2015. And, as we stand on the brink of a seismic revolution in our worldview, he brings us up to speed on the greatest challenge ever to confront physics.

Book Description
The Alexander Technique (AT) is a remarkably simple but powerful method for learning to skillfully control how your brain and body interact, allowing you to better coordinate your movements while increasing the accuracy of your mind's thoughts and perceptions. Now, in How You Stand, How You Move, How You Live, leading Alexander Technique master teacher Missy Vineyard sheds a completely fresh light on this revolutionary method and, in the process, offers path-breaking insight into the mind-body connection. Vineyard thoroughly explains and teaches the central skills of the AT through simple self-experiments, and she offers engaging stories of students in their lessons to show its effective application across a range of disciplines, including the performing arts, athletics, health, psychology, and education. How You Stand, How You Move, How You Live introduces us to a world within ourselves that we know surprisingly little about--and thereby helps us to understand why we often cannot do what we should be able to do, why we harm ourselves with chronic tension and anxiety, and why our thoughts often seem beyond our control. Vineyard is also the first AT teacher to draw on cutting-edge research in neuroscience and to synthesize those findings with AT theories and techniques. She fully illuminates the benefits to be reaped by mastery of the Alexander Technique, which include: Release from acute or chronic physical pain Enhanced mental attention and focus Reduced anxiety Improved balance and coordination Relief from tension and stress Increased ease and efficiency performing precise movement skills

Book Description
The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues.Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.

Book Description
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.

Book Description
Functional training develops the attributes and abilities required to perform tasks, skills and activities useful and relevant to daily life. Functional Exercise and Rehabilitation serves as an accessible and visual guide providing the essentials of therapeutic exercise and rehabilitation, including mobilization, stabilization and myofascial release. This book begins by explaining functional training and the foundation of the STRIVE approach. Chapter 2 introduces functional anatomy and Chapter 3 explains the fundamentals of neuroscience. The final chapters discuss the STRIVE principles and apply them to exercise, program design and injury recovery. Each chapter includes key point boxes, illustrations and photos of exercises discussed. Written by an exercise specialist and osteopath, this practical guide is presented in an easy-to-read style. Functional Exercise and Rehabilitation is essential reading for all health professionals, sports therapists and trainers involved in exercise prescription.
