Download or read book Traveling at the Speed of Thought written by Daniel Kennefick and published by Princeton University Press. This book was released on 2007-04-15 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Einstein first described them nearly a century ago, gravitational waves have been the subject of more sustained controversy than perhaps any other phenomenon in physics. These as yet undetected fluctuations in the shape of space-time were first predicted by Einstein's general theory of relativity, but only now, at the dawn of the twenty-first century, are we on the brink of finally observing them. Daniel Kennefick's landmark book takes readers through the theoretical controversies and thorny debates that raged around the subject of gravitational waves after the publication of Einstein's theory. The previously untold story of how we arrived at a settled theory of gravitational waves includes a stellar cast from the front ranks of twentieth-century physics, including Richard Feynman, Hermann Bondi, John Wheeler, Kip Thorne, and Einstein himself, who on two occasions avowed that gravitational waves do not exist, changing his mind both times. The book derives its title from a famously skeptical comment made by Arthur Stanley Eddington in 1922--namely, that "gravitational waves propagate at the speed of thought." Kennefick uses the title metaphorically to contrast the individual brilliance of each of the physicists grappling with gravitational-wave theory against the frustratingly slow progression of the field as a whole. Accessibly written and impeccably researched, this book sheds new light on the trials and conflicts that have led to the extraordinary position in which we find ourselves today--poised to bring the story of gravitational waves full circle by directly confirming their existence for the very first time.

Book excerpt: "In the near future, disease will be a condition of the past. Most genetic defects will be removed at birth; the remaining during infancy. Unfortunately, there will be a generation left behind. For members of that missed generation, small advances will be made. Through various programs, they will be taught to get along in the world despite their differences. They will be made active and contributing members of society. But they will never be normal. Lou Arrendale is a member of that lost generation, born at the wrong time to reap the awards of medical science. Part of a small group of high-functioning autistic adults, he has a steady job with a pharmaceutical company, a car, friends, and a passion for fencing. Aside from his annual visits to his counselor, he lives a low-key, independent life. He has learned to shake hands and make eye contact. He has taught himself to use "please" and "thank you" and other conventions of conversation because he knows it makes others comfortable. He does his best to be as normal as possible and not to draw attention to himself. But then his quiet life comes under attack. It starts with an experimental treatment that will reverse the effects of autism in adults. With this treatment Lou would think and act and "be just like everyone else. But if he was suddenly free of autism, would he still be himself? Would he still love the same classical music-with its complications and resolutions? Would he still see the same colors and patterns in the world-shades and hues that others cannot see? Most importantly, would he still love Marjory, a woman who may never be able to reciprocate his feelings? Would it be easier for her to return the love of a"normal"? There are intense pressures coming from the world around him-including an angry supervisor who wants to cut costs by sacrificing the supports necessary to employ autistic workers. Perhaps even more disturbing are the barrage of questions within himself. For Lou must decide if he should submit to a surgery that might completely change the way he views the world . . . and the very essence of who he is. Thoughtful, provocative, poignant, unforgettable, "The Speed of Dark is a gripping exploration into the mind of an autistic person as he struggles with profound questions of humanity and matters of the heart.
Download or read book Luminous Darkness written by Deborah Eden Tull and published by Shambhala Publications. This book was released on 2022-09-27 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: A resonant call to explore the darkness in life, in nature, and in consciousness—including difficult emotions like uncertainty, grief, fear, and xenophobia—through teachings, embodied meditations, and mindful inquiry that provide us with a powerful path to healing. Darkness is deeply misunderstood in today’s world; yet it offers powerful medicine, serenity, strength, healing, and regeneration. All insight, vision, creativity, and revelation arise from darkness. It is through learning to stay present and meet the dark with curiosity rather than judgment that we connect to an unwavering light within. Welcoming darkness with curiosity, rather than fear or judgment, enables us to access our innate capacity for compassion and collective healing. Dharma teacher, shamanic practitioner, and deep ecologist Deborah Eden Tull addresses the spiritual, ecological, psychological, and interpersonal ramifications of our bias towards light. Tull explores the medicine of darkness for personal and collective healing, through topics such as: Befriending the Night: The Radiant Teachings of Darkness Honoring Our Pain for Our World Seeing in the Dark: The Quiet Power of Receptivity Dreams, Possibility, and Moral Imagination Releasing Fear—Embracing Emergence Tull shows us how the labeling of darkness as “negative” becomes a collective excuse to justify avoiding everything that makes us uncomfortable: racism, spiritual bypass, environmental destruction. We can only find the radical path to wholeness by learning to embrace the interplay of both darkness and light.

Download or read book River of Darkness written by Buddy Levy and published by Diversion Books. This book was released on 2022-04-05 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The acclaimed author of Labyrinth of Ice charts the legendary sixteenth-century adventurer’s death-defying navigation of the Amazon River. In 1541, Spanish conquistador Gonzalo Pizarro and his lieutenant Francisco Orellana searched for La Canela, South America’s rumored Land of Cinnamon, and the fabled El Dorado, “the golden man.” Quickly, the enormous expedition of mercenaries, enslaved natives, horses, and hunting dogs were decimated through disease, starvation, and attacks in the jungle. Hopelessly lost in the swampy labyrinth, Pizarro and Orellana made the fateful decision to separate. While Pizarro eventually returned home in rags, Orellana and fifty-seven men continued into the unknown reaches of the mighty Amazon jungle and river. Theirs would be the greater glory. Interweaving historical accounts with newly uncovered details, Levy reconstructs Orellana’s journey as the first European to navigate the world’s largest river. Every twist and turn of the powerful Amazon holds new wonders and the risk of death. Levy gives a long-overdue account of the Amazon’s people—some offering sustenance and guidance, others hostile, subjecting the invaders to gauntlets of unremitting attacks and signs of terrifying rituals. Violent and beautiful, noble and tragic, River of Darkness is riveting history and breathtaking adventure that will sweep readers on a voyage unlike any other. Praise for Buddy Levy and River of Darkness “In River of Darkness, Buddy Levy recounts Orellana’s headlong dash down the Amazon. Like Mr. Levy’s last book, Conquistador, about the conquest of Mexico, River of Darkness presents a fast-moving tale of triumph over seemingly insurmountable odds. . . . Though impromptu, the expedition was one of the most amazing adventures of all time.” —Wall Street Journal “An exciting, well-plotted excursion down the Amazon River with the early Spanish conquistador. . . . [A] richly textured account of the rogue, rebel and visionary whose discovery still resonates today.” —Kirkus Reviews “A rollicking adventure . . . Levy successfully conveys the Amazon’s power and majesty, while shedding light on the futility of humanity’s attempt to tame it.” —The A.V. Club

Download or read book Darkness Descending written by Ken Jones and published by Quercus. This book was released on 2015-06-02 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: In January 2003, Ken Jones, an adventurer and former British Special Forces soldier, was caught in a devastating avalanche as he climbed deep in the frozen wilderness of Romania's Carpathian Mountains. Swept over the edge of a 75-foot cliff, he plummeted to the rocks below. Against all odds, he survived the fall--regaining consciousness shrouded in darkness and sub-zero temperatures, separated from his supplies, and in excruciating pain from a broken leg and shattered pelvis. With frostbite and internal bleeding beginning to take their toll, Jones summoned his deepest will to live and began three agonizing days dragging himself over frozen terrain to safety--only to discover that his true ordeal was yet to begin. The doctors who initially treated him were astonished that any person could sustain such massive trauma and exposure and still be alive. Then, after an initial round of extensive surgeries and recoveries that equaled if not exceeded the pain of the injuries themselves, Jones was told he would almost certainly never walk again. Over the next two years he endured constant physical therapy and additional surgery, with latent effects from the fall still threatening his life. At one point, he slipped into unconsciousness under anesthesia just as he heard a doctor telling his mother he was going to die. But with a soldier's heart he made his way to recovery, regained full mobility, and has made his story known in this remarkable book. In the bestselling tradition of Into Thin Air and Touching the Void, Darkness Descending is a classic tale of triumph over adversity and what it means to never give up. Jones's remarkable feat has already been featured on Animal Planet's hit series I Shouldn't Be Alive, and stands tall as an unforgettable testament to the strength of the human spirit.

Book excerpt: NATIONAL BESTSELLER • From one of the world’s leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes “an astonishing ride” through the universe (The New York Times) that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.
