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.

Available in PDF, EPUB and Kindle. Book excerpt: An intimate journey across America, as told by one of its most beloved writers A Penguin Classic In September 1960, John Steinbeck embarked on a journey across America. He felt that he might have lost touch with the country, with its speech, the smell of its grass and trees, its color and quality of light, the pulse of its people. To reassure himself, he set out on a voyage of rediscovery of the American identity, accompanied by a distinguished French poodle named Charley; and riding in a three-quarter-ton pickup truck named Rocinante. His course took him through almost forty states: northward from Long Island to Maine; through the Midwest to Chicago; onward by way of Minnesota, North Dakota, Montana (with which he fell in love), and Idaho to Seattle, south to San Francisco and his birthplace, Salinas; eastward through the Mojave, New Mexico, Arizona, to the vast hospitality of Texas, to New Orleans and a shocking drama of desegregation; finally, on the last leg, through Alabama, Virginia, Pennsylvania, and New Jersey to New York. Travels with Charley in Search of America is an intimate look at one of America's most beloved writers in the later years of his life—a self-portrait of a man who never wrote an explicit autobiography. Written during a time of upheaval and racial tension in the South—which Steinbeck witnessed firsthand—Travels with Charley is a stunning evocation of America on the eve of a tumultuous decade. This Penguin Classics edition includes an introduction by Jay Parini. For more than seventy years, Penguin has been the leading publisher of classic literature in the English-speaking world. With more than 1,700 titles, Penguin Classics represents a global bookshelf of the best works throughout history and across genres and disciplines.

Download or read book Eureka written by Edgar Allan Poe and published by . This book was released on 2017-04-18 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eureka (1848) is a lengthy non-fiction work by American author Edgar Allan Poe (1809–1849) which he subtitled "A Prose Poem", though it has also been subtitled as "An Essay on the Material and Spiritual Universe". Adapted from a lecture he had presented, Eureka describes Poe's intuitive conception of the nature of the universe with no antecedent scientific work done to reach his conclusions. He also discusses man's relationship with God, whom he compares to an author. It is dedicated to the German naturalist and explorer Alexander von Humboldt (1769–1859). Though it is generally considered a literary work, some of Poe's ideas anticipate 20th century scientific discoveries and theories. Indeed a critical analysis of the scientific content of Eureka reveals a non-causal correspondence with modern cosmology due to the assumption of an evolving Universe, but excludes the anachronistic anticipation of relativistic concepts such as black holes. Eureka was received poorly in Poe's day and generally described as absurd, even by friends. Modern critics continue to debate the significance of Eureka and some doubt its seriousness, in part because of Poe's many incorrect assumptions and his comedic descriptions of well-known historical minds. It is presented as a poem, and many compare it with his fiction work, especially science fiction stories such as "The Facts in the Case of M. Valdemar". His attempts at discovering the truth also follow his own tradition of "ratiocination", a term used in his detective fiction tales. Poe's suggestion that the soul continues to thrive even after death also parallels with works in which characters reappear from beyond the grave such as "Ligeia". The essay is oddly transcendental, considering Poe's disdain for that movement. He considered it his greatest work and claimed it was more important than the discovery of gravity. Eureka is Poe's last major work and his longest non-fiction work at nearly 40,000 words in length.
