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.
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 recognised 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.

For physicists and applied mathematicians working in the fields of relativity and cosmology, high-energy physics and field theory, thermodynamics, fluid dynamics and mechanics. This book provides an introduction to the concepts and techniques of modern differential theory, particularly Lie groups, Lie forms and differential forms.
The present volume aims to be a comprehensive survey on the derivation of the equations of motion, both in General Relativity as well as in alternative gravity theories. The topics covered range from the description of test bodies, to self-gravitating (heavy) bodies, to current and future observations. Emphasis is put on the coverage of various approximation methods (e.g., multipolar, post-Newtonian, self-force methods) which are extensively used in the context of the relativistic problem of motion. Applications discussed in this volume range from the motion of binary systems -- and the gravitational waves emitted by such systems -- to observations of the galactic center. In particular the impact of choices at a fundamental theoretical level on the interpretation of experiments is highlighted. This book provides a broad and up-do-date status report, which will not only be of value for the experts working in this field, but also may serve as a guideline for students with background in General Relativity who like to enter this field.

You don't have to be an entrepreneur to think like one and take flight with your dreams. Too often we remain in jobs that stifle our souls and leave us on the runway of opportunity with the engine of our deepest passion stalled, watching others make their personal vision a reality and build a legacy for their children-the opposite of what God intends for us. But it's never too late to get your dreams off the ground! If you long to maximize your unique abilities and aptitudes, if you strive to combine personal fulfillment with professional satisfaction, if you dream of creating exceptional goods and offering transformative services and fulfilling God's destiny for you, then you are ready to SOAR! In SOAR! T.D. Jakes reveals how to build the uniquely personal vision within each of us into our special contribution to the world. Blending the practical business acumen of a successful, global CEO with the dynamic inspiration of a life coach, SOAR! provides the tools needed to ignite our imaginations into action and challenges us to embrace our God-given purpose as we align our character and creativity with our careers. Bridging both the corporate and nonprofit worlds, SOAR! is a practical and easy-to-follow flight plan for launching the entrepreneurial drive inside each of us. It provides an inspiring look into the mindset of people who don't wait to see what will happen but strategically build the wings that will take them to new heights. So buckle your seat belts and prepare for liftoff-you have been cleared to fly beyond your fears, to absolutely SOAR!
NASA's history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America's space agency wasn't created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. In the 1930s, rockets were all the rage in Germany, the focus both of scientists hoping to fly into space and of the German armed forces, looking to circumvent the restrictions of the Treaty of Versailles. One of the key figures in this period was Wernher von Braun, an engineer who designed the rockets that became the devastating V-2. As the war came to its chaotic conclusion, von Braun escaped from the ruins of Nazi Germany, and was taken to America where he began developing missiles for the US Army. Meanwhile, the US Air Force was looking ahead to a time when men would fly in space, and test pilots like Neil Armstrong were flying cutting-edge, rocket-powered aircraft in the thin upper atmosphere. Breaking the Chains of Gravity tells the story of America's nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military. At this point getting a man in space became a national imperative, leading to the creation of the National Aeronautics and Space Administration, otherwise known as NASA.
What goes up must come down. Everybody knows that. But what is it that pulls everything from rocks to rockets toward the center of the earth? It's gravity. Nobody can say exactly what it is, but gravity is there, pulling on everything, all the time. With the help of an adventurous scientist and his fun-loving dog, you can read and find out about this mysterious force.
Sixth-grader Simon Bloom can?t believe his luck when he finds a book that enables him to control the laws of physics. By simply reciting the formulas it contains, he can cancel gravity to fly around his bedroom, or decrease friction so he can slide down the street as if he were on Rollerblades. When two thugs with evil intentions come after Simon, he must use the formulas to save himself and the book from falling into their hands. This funny, fast, and imaginative novel from first-time author Michael Reisman will appeal to fans of both fantasy and action-adventure.
Winner of the 1974 National Book Award “A screaming comes across the sky. . .” A few months after the Germans’ secret V-2 rocket bombs begin falling on London, British Intelligence discovers that a map of the city pinpointing the sexual conquests of one Lieutenant Tyrone Slothrop, U.S. Army, corresponds identically to a map showing the V-2 impact sites. The implications of this discovery will launch Slothrop on an amazing journey across war-torn Europe, fleeing an international cabal of military-industrial superpowers, in search of the mysterious Rocket 00000, through a wildly comic extravaganza that has been hailed in The New Republic as “the most profound and accomplished American novel since the end of World War II.”
