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.

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.

The proceedings of the 2nd LeCosPA International Symposium, 'Everything about Gravity', collects 78 papers contributed by the symposium's Plenary Session and Parallel Session speakers. Organizers of the Parallel Sessions have in addition prepared summaries for their own sessions. The topics range from quasi-local energy in GR in the presence of gravitational radiations, a gauge theory perspective of gravity, naked black hole firewalls related to the black hole information loss paradox, a new theory of spacetime quantization, relations between the Schwinger effect and the Hawking radiation and Unruh effect, conformal frames in cosmology, surprises in nonrelativistic naturalness, inflation and tensor fluctuations, emergent spacetime for quantum gravity, understanding strongly coupled magnetism through holographic principle, the detections of dark matter, ultra-high energy cosmic neutrinos and cosmic rays, etc. Last but not least, the closing remark delivered by John Ellis raised the following question: Does cosmological inflation require a modification of Einstein's gravity?After 100 years of remarkable success of Einstein's general relativity, the development of a successful quantum theory of gravity has become a major goal in physics in the 21st century. This volume serves as a valuable reference for scientists who are interested in frontier research topics of gravity.

New York Times best-selling author Caroline Myss draws from her years as a medical intuitive to show that healing is not only physical; it is also a mystical phenomenon that transcends reason. Inspired by ordinary people who overcame a wide array of physical and psychological ailments—from rheumatoid arthritis to cancer—Caroline dove into the works of the great mystics to gain a deeper understanding of healing’s spiritual underpinnings. Based on these studies, she demonstrates how conventional and holistic medicine often fall short in times of need. Both systems rely upon a logical approach to curing illness when there is nothing reasonable about the emotional, psychological, or spiritual influences behind any ailment. Integral to this mystical healing approach is the engagement of the soul, which we experience through exploring our seven shadow passions, building an empowered inner self around our seven inherent graces, and learning how to work with the mystical laws that govern it. This knowledge holds the key to understanding what it means to defy gravity and break through the boundaries of ordinary thought. You can heal any illness. You can channel grace. And you can learn to live fearlessly.

“[An] absorbing novel that will appeal to fans of Rainbow Rowell.” —Booklist “A poignant and carefully crafted story.” —School Library Journal “A gorgeous, sad, funny, and wise book about letting go and finding your place in the world.” —Kathleen Glasgow, New York Times bestselling author of Girl in Pieces Parker struggles to reconnect with her twin brother, Charlie—who’s recovering from cancer—as she tries to deal with her anxiety about the future in this powerful new novel. Twins Parker and Charlie are polar opposites. Where Charlie is fearless, Parker is careful. Charlie is confident while Parker aims to please. Charlie is outgoing and outspoken; Parker is introverted and reserved. And of course, there’s the one other major difference: Charlie got cancer. Parker didn’t. But now that Charlie is officially in remission, life couldn’t be going better for Parker. She’s landed a prestigious summer internship at the hospital and is headed to Harvard in the fall to study pediatric oncology—which is why the anxiety she’s felt since her Harvard acceptance is so unsettling. And it doesn’t help that her relationship with Charlie has been on the rocks since his diagnosis. Enter Finn, a boy who’s been leaving strange graffiti messages all over town. Parker can’t stop thinking about those messages, or about Finn, who makes her feel free for the first time: free to doubt, free to make mistakes, and free to confront the truth that Parker has been hiding from for a long time. That she keeps trying to save Charlie, when the person who really needs saving is herself.

“This gracefully written history of twentieth-century gravity research” brings to life the discoveries and developments that confirmed the theory of relativity (Publishers Weekly, starred review). Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time. A century later, the Event Horizon Telescope examined the space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way, to determine whether Einstein was right on the details. In Gravity’s Century, award-winning science writer Ron Cowen brings to life the incredible scientific journey between these two events and sheds light on their groundbreaking implications. From the development of radio telescopes to the discovery of black holes and quasars, and the still-unresolved place of gravity in quantum theory, Cowen breaks down the physics in clear and approachable language. Gravity’s Century vividly demonstrates how the quest to understand gravity is really the quest to comprehend the universe./
