Available in PDF, EPUB and Kindle. Book excerpt: According to the theory of relativity, we are constantly bathed in gravitational radiation. When stars explode or collide, a portion of their mass becomes energy that disturbs the very fabric of the space-time continuum like ripples in a pond. But proving the existence of these waves has been difficult; the cosmic shudders are so weak that only the most sensitive instruments can be expected to observe them directly. Fifteen times during the last thirty years scientists have claimed to have detected gravitational waves, but so far none of those claims have survived the scrutiny of the scientific community. Gravity's Shadow chronicles the forty-year effort to detect gravitational waves, while exploring the meaning of scientific knowledge and the nature of expertise. Gravitational wave detection involves recording the collisions, explosions, and trembling of stars and black holes by evaluating the smallest changes ever measured. Because gravitational waves are so faint, their detection will come not in an exuberant moment of discovery but through a chain of inference; for forty years, scientists have debated whether there is anything to detect and whether it has yet been detected. Sociologist Harry Collins has been tracking the progress of this research since 1972, interviewing key scientists and delineating the social process of the science of gravitational waves. Engagingly written and authoritatively comprehensive, Gravity's Shadow explores the people, institutions, and government organizations involved in the detection of gravitational waves. This sociological history will prove essential not only to sociologists and historians of science but to scientists themselves.

Download or read book Analytical Description of Black Holes Shadow written by Singh Balendra Pratap and published by Independent Author. This book was released on 2023-03-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1905, Einstein presented the special theory of relativity where he determined that the laws of physics appear same in all inertial frames and the speed of light is constant in vacuum. After the discovery of special theory of relativity, Einstein took another ten years to include acceleration in his theory and in 1915 he established the general theory of relativity for an accelerating observer [1]. The general relativity (GR) is a theory of gravity in which Einstein presented a unified picture of space and time, well known as spacetime which was abandoned by Newtonian gravity [2]. One of the most interesting and intriguing prediction of GR is the existence of black holes in our universe. Black holes are the region in the spacetime where the gravitational pull is so high that even light cannot escape from it. Black holes are the most exotic astrophysical objects due to its unique behavior and a black hole solution can be found by solving Einstein field equations.
Download or read book Gravity s Kiss written by Harry Collins and published by MIT Press. This book was released on 2017-01-20 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating account, written in real time, of the unfolding of a scientific discovery: the first detection of gravitational waves. Scientists have been trying to confirm the existence of gravitational waves for fifty years. Then, in September 2015, came a “very interesting event” (as the cautious subject line in a physicist's email read) that proved to be the first detection of gravitational waves. In Gravity's Kiss, Harry Collins—who has been watching the science of gravitational wave detection for forty-three of those fifty years and has written three previous books about it—offers a final, fascinating account, written in real time, of the unfolding of one of the most remarkable scientific discoveries ever made. Predicted by Einstein in his theory of general relativity, gravitational waves carry energy from the collision or explosion of stars. Dying binary stars, for example, rotate faster and faster around each other until they merge, emitting a burst of gravitational waves. It is only with the development of extraordinarily sensitive, highly sophisticated detectors that physicists can now confirm Einstein's prediction. This is the story that Collins tells. Collins, a sociologist of science who has been embedded in the gravitational wave community since 1972, traces the detection, the analysis, the confirmation, and the public presentation and the reception of the discovery—from the first email to the final published paper and the response of professionals and the public. Collins shows that science today is collaborative, far-flung (with the physical location of the participants hardly mattering), and sometimes secretive, but still one of the few institutions that has integrity built into it.

Download or read book THE THEORY OF LIGHT GRAVITY written by Colin Parkes and published by Xlibris Corporation. This book was released on 2011-01-13 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some discoveries have shaken the world and left their mark in an important way. Newton’s Theory of Gravity, Darwin’s Theory of Evolution and Einstein’s Theories of Relativity come immediately to mind. One thing they have in common is a bold and brave new idea. When these new theories are eventually accepted they become pillars of science and more importantly foundations of society. Then, occasionally a new idea comes along that rattles one of these pillars. My new idea should do just that, shake but not topple our theory of gravity. Hopefully it will bring gravity to the masses not just add more mass to gravity theory. It solves Newton’s mystery and Einstein’s enigma, supports most current gravity theory, but adds a new dimension to physics and will become a major part of the new gravity pillar of physics.

Available in PDF, EPUB and Kindle. Book excerpt: In his author-illustrator debut, Coretta Scott King-John Steptoe–and Africana Book Award–winning illustrator Charly Palmer spins a tall tale about a neighborhood basketball hero. Have you ever heard of Gravity? No, not gravity, the centrifugal force pulling us to the Earth. I'm talking about Gravity--the greatest ball player to ever lace up a pair of sneakers. Gravity is the new kid on the Hillside Projects basketball team, the Eagles. He once jumped so high that his teammates went out for ice cream before he came back down. With Gravity on their side, the Eagles feel unstoppable. They’re ready to win “The Best of the Best,” Milwaukee’s biggest and baddest pick-up basketball tournament. But when they face-off with the Flyers in the final round, the winningest team in the whole city, they realize that it may take a little more than Gravity to bring them to victory. Here is a clever, energetic story about the unsung superstars walking among us, complete with vivid art and heartfelt themes of teamwork, loyalty, friendship, and fun.
Download or read book Extra Dimensions in Space and Time written by Itzhak Bars and published by Springer Science & Business Media. This book was released on 2009-12-04 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: In physics, the idea of extra spatial dimensions originates from Nordstöm’s 5-dimensional vector theory in 1914, followed by Kaluza-Klein theory in 1921, in an effort to unify general relativity and electromagnetism in a 5 dimensional space-time (4 dimensions for space and 1 for time). Kaluza–Klein theory didn’t generate enough interest with physicist for the next five decades, due to its problems with inconsistencies. With the advent of supergravity theory (the theory that unifies general relativity and supersymmetry theories) in late 1970’s and eventually, string theories (1980s) and M-theory (1990s), the dimensions of space-time increased to 11 (10-space and 1-time dimension). There are two main features in this book that differentiates it from other books written about extra dimensions: The first feature is the coverage of extra dimensions in time (Two Time physics), which has not been covered in earlier books about extra dimensions. All other books mainly cover extra spatial dimensions. The second feature deals with level of presentation. The material is presented in a non-technical language followed by additional sections (in the form of appendices or footnotes) that explain the basic equations and formulas in the theories. This feature is very attractive to readers who want to find out more about the theories involved beyond the basic description for a layperson. The text is designed for scientifically literate non-specialists who want to know the latest discoveries in theoretical physics in a non-technical language. Readers with basic undergraduate background in modern physics and quantum mechanics can easily understand the technical sections. Part I starts with an overview of the Standard Model of particles and forces, notions of Einstein’s special and general relativity, and the overall view of the universe from the Big Bang to the present epoch, and covers Two-Time physics. 2T-physics has worked correctly at all scales of physics, both macroscopic and microscopic, for which there is experimental data so far. In addition to revealing hidden information even in familiar "everyday" physics, it also makes testable predictions in lesser known physics regimes that could be analyzed at the energy scales of the Large Hadron Collider at CERN or in cosmological observations." Part II of the book is focused on extra dimensions of space. It covers the following topics: The Popular View of Extra Dimensions, Einstein and the Fourth Dimension, Traditional Extra Dimensions, Einstein's Gravity, The Theory Formerly Known as String, Warped Extra Dimensions, and How Do We Look For Extra Dimensions?
Download or read book Gravity How Gravity Is Created written by Peter Roberts and published by Lulu.com. This book was released on 2018 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.]"

Download or read book Gravity from the Ground Up written by Bernard Schutz and published by Cambridge University Press. This book was released on 2003-12-04 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Practice of Light written by Sean Cubitt and published by MIT Press. This book was released on 2014-09-05 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: An account of Western visual technologies since the Renaissance traces a history of the increasing control of light's intrinsic excess. Light is the condition of all vision, and the visual media are our most important explorations of this condition. The history of visual technologies reveals a centuries-long project aimed at controlling light. In this book, Sean Cubitt traces a genealogy of the dominant visual media of the twenty-first century—digital video, film, and photography—through a history of materials and practices that begins with the inventions of intaglio printing and oil painting. Attending to the specificities of inks and pigments, cathode ray tubes, color film, lenses, screens, and chips, Cubitt argues that we have moved from a hierarchical visual culture focused on semantic values to a more democratic but value-free numerical commodity. Cubitt begins with the invisibility of black, then builds from line to surface to volume and space. He describes Rembrandt's attempts to achieve pure black by tricking the viewer and the rise of geometry as a governing principle in visual technology, seen in Dürer, Hogarth, and Disney, among others. He finds the origins of central features of digital imaging in nineteenth-century printmaking; examines the clash between the physics and psychology of color; explores the representation of space in shadows, layers, and projection; discusses modes of temporal order in still photography, cinema, television, and digital video; and considers the implications of a political aesthetics of visual technology.
