Gravity is not a force acting at a distance. It is mass gripping spacetime, telling it how to curve, and spacetime gripping mass, telling it how to move. According to preeminent physicist John Archibald Wheeler, gravity makes the closest connection between the world we see around us and the inner-most workings of the universe. In this imaginative volume, Wheeler explores gravity and spacetime by applying Einstein's battle-tested theory to both familiar and exotic phomomena--everything from flying tennis balls, to hurling gravity waves from crashing stars, the motion of the planets, and the collapse of a star into a black hole. It's a provocative, revealing, fully engaging scientific journey led by a frontline participant in the most important work in physics in the last 50 years.

Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

This is the first reasoned, and supported theory ever published explaining how gravity is created. Neither Newton nor Einstein could do this. Whereas relativity is a theory that explains how matter responds to gravity, this book describes how gravity is created and the mechanisms by which gravity exerts its influence on matter from atoms to planets, stars, and galaxies. It also provides, again, for the first time, a mechanism for inertia and momentum and discusses an improved version of Newton's equation. All in simple language that anyone can understand. Written without mathematics for everyone from students to professional astronomers, this book has received many unsolicited five-star rating testimonials, from youngsters to PhD scientists, many of which are reproduced on its second and third pages, including: "Newton was reported to have stated that his work was relevant only because he could stand on the shoulders of past giants. Your work is, of course, a step beyond. [H.G.K.]"

The lectures that four authors present in this volume investigate core topics related to the accelerated expansion of the Universe. Accelerated expansion occured in the ?36 very early Universe – an exponential expansion in the in ationary period 10 s after the Big Bang. This well-established theoretical concept had rst been p- posed in 1980 by Alan Guth to account for the homogeneity and isotropy of the observable universe, and simultaneously by Alexei Starobinski, and has since then been developed by many authors in great theoretical detail.

From a New York Times bestselling and Hugo award-winning author comes a modern masterwork of science fiction, introducing a captain, his crew, and a detective as they unravel a horrifying solar system wide conspiracy that begins with a single missing girl. Now a Prime Original series. Humanity has colonized the solar system—Mars, the Moon, the Asteroid Belt and beyond—but the stars are still out of our reach. Jim Holden is XO of an ice miner making runs from the rings of Saturn to the mining stations of the Belt. When he and his crew stumble upon a derelict ship, the Scopuli, they find themselves in possession of a secret they never wanted. A secret that someone is willing to kill for—and kill on a scale unfathomable to Jim and his crew. War is brewing in the system unless he can find out who left the ship and why. Detective Miller is looking for a girl. One girl in a system of billions, but her parents have money and money talks. When the trail leads him to the Scopuli and rebel sympathizer Holden, he realizes that this girl may be the key to everything. Holden and Miller must thread the needle between the Earth government, the Outer Planet revolutionaries, and secretive corporations—and the odds are against them. But out in the Belt, the rules are different, and one small ship can change the fate of the universe. "Interplanetary adventure the way it ought to be written." —George R. R.

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.
