The weirdly alien notion of a space-time abyss from which nothing escapes—not even light—seemed to confound all logic. This engrossing book tells the story of the fierce black hole debates and the contributions of Einstein and Hawking and other leading thinkers who completely altered our view of the universe. Renowned science writer Marcia Bartusiak shows how the black hole helped revive Einstein’s greatest achievement, the general theory of relativity, after decades during which it had been pushed into the shadows. Not until astronomers discovered such surprising new phenomena as neutron stars and black holes did the once-sedate universe transform into an Einsteinian cosmos, filled with sources of titanic energy that can be understood only in the light of relativity. This book celebrates the hundredth anniversary of general relativity, uncovers how the black hole really got its name, and recounts the scientists’ frustrating, exhilarating, and at times humorous battles over the acceptance of one of history’s most dazzling ideas.

    Once the old, cantankerous Sam Clevenger and his wife, Charlotte, hired Frank Willson and John Johnson to help with the move, their fate took a dark turn. These true events were documented by journalists through the 1887 trial and well into the 1900s, and stories have been told of Sam’s unfound treasure for nearly 130 years. But, this is the first detailed, documented, and vetted account of their bizarre and fascinating tale.

    Siracusa's overview, wrap-up, and critique of everything new in OS X 10.10 Yosemite.

    Mainstream science, however has suppressed these facts. Prejudices based on scientific theory act as a 'knowledge filter', giving us a picture of prehistory that is largely inaccurate. This book reveals this hidden history.

    Indeed, many physicists today believe that there are other dimensions beyond the four of our space-time, and that a unified vision of the various forces of nature can be achieved, if we consider that everything we see around us, from the trees to the stars are nothing but vibrations in hyperspace. Hyperspace theory - and its more recent derivation, superstring theory - is the eye of this revolution. In this book, Michio Kaku shows us a fascinating panorama, which completely changes our view of the cosmos, and takes us on a dazzling journey through new dimensions: wormholes connecting parallel universes, time machines, "baby universes" and more. Similar wonders are emerging in some pages in which everything is explained with elegant simplicity and where the mathematical formulation is replaced by imaginative illustrations that allow the problems to be visualized. The result is a very entertaining and surprising book, which even leaves behind the greatest fantasies of the old science fiction authors.

    

    Destiny had other plans for her: summoned to Russia, then considered by most Europeans to be a vast, primitive wasteland, devoid of culture or sophistication, she became the Grand Duchess Ekaterina, wife of the future emperor Peter III. What followed her short, unhappy marriage was a legendary rise to supreme power. At the age of 33, the Grand Duchess Catherine became the Empress Catherine II, ruler in her own right of the largest empire on earth. In this book, you will learn how, during Catherine’s lonely years as a neglected wife in the court of the Empress Elisabeth, she bided her time and amassed the necessary political and military support to overthrow the heir to the Romanov dynasty and seize his throne. You will also learn why, over the course of her 34-year reign, which saw rebellions, foreign wars, popular uprisings, and a string of jealous lovers vying for her favor, she came to be remembered by history under the name conferred upon her by her own people: Catherine the Great.

    That fall, the Black Knights of Army were the class of the nation. Mark Beech, a second-generation West Pointer, recounts this memorable and never-to-be-repeated season with:- Pete Dawkins, the Heisman Trophy winner who rose to the rank of Brigadier General - The long-reclusive Bill Carpenter, the fabled "lonesome end" who earned the Distinguished Service Cross for saving his company in Vietnam - Red Blaik, who led Army back to glory after the cribbing scandal and had the field at Michie Stadium named in his honorCombining the triumph of The Junction Boys with the heroics of The Long Gray Line, Beech captures a unique period in the history of football, the military, and mid-twentieth-century America.

    

    But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments. As a result, questioning the status quo long meant professional ruin. And yet, from the 1920s to today, physicists like John Bell, David Bohm, and Hugh Everett persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and of the courageous scientists who dared to stand up for truth.

    Tobias Dantzig shows that the development of math—from the invention of counting to the discovery of infinity—is a profoundly human story that progressed by “trying and erring, by groping and stumbling.” He shows how commerce, war, and religion led to advances in math, and he recounts the stories of individuals whose breakthroughs expanded the concept of number and created the mathematics that we know today.

    The book chronicles the 2008 season, during which the team suffered its second worst record ever and Head Coach Phil Fulmer, the most beloved and recognized man in Tennessee, was fired. Author of Dixieland Delight, Clay Travis offers a fascinating inside look at the inner workings of a major college sports program, and chronicles a season of promise that went terribly wrong, ending a long, fabled era.

    But something went terribly wrong. By day's end, some would be alive. Others would not. A close-knit community would be devastated, forced to endure. This gripping true story centers on what happened to one courageous and flawed young man who survived, and how his life quickly spiraled out of control in the next two years. It is a story about love, unbreakable friendship, and "king" corn. “There are some forty-five thousand items in the average American supermarket and more than a quarter of them now contain corn,” writes Michael Pollan in The Omnivore’s Dilemma. But as international dependence on the highly subsidized crop for cattle feed, corn syrup and ethanol has surged—so have deaths by corn. Based on three years of reporting and interviews with the people involved and thousands of pages of court documents, transcripts, police reports, journalist Erika Hayasaki brings to life (in narrative nonfiction-style) this world of people who risk and sometimes lose their lives for this powerful commodity. Hayasaki, a former national correspondent for the Los Angeles Times, is the author of The Death Class: A True Story About Life (Simon & Schuster 2014), as well as the Kindle Single, Dead or Alive (2012). She is an assistant professor in the Literary Journalism Program at the University of California, Irvine, and a regular contributor to Newsweek and The Atlantic. *Cover design by Kristen RadtkePraise for DROWNED BY CORN:THE CHICAGO TRIBUNE: "The descriptions of the accident are chilling: a blow-by-blow account of the grain pulling the young men under and the dramatic rescue of Will, who survived after being buried past his chest. The piece follows Will as his grief sends him into a downward spiral. "Drowned by Corn" is a gripping narrative of tenderness and horror, friendship and loss." — Megan KirbySAN FRANCISCO CHRONICLE: "Erika Hayasaki’s suspenseful account of the deaths of Paco and Wyatt and the harrowing rescue of Will is the stuff of nightmares. But what elevates this fine work of investigative journalism is her portrayal of Will in the aftermath: his survival guilt, his struggle with alcohol and drugs, his strained relationships and his eventual discovery of a way to endure his and his town’s unspeakable losses." — Porter Shreve
