    Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out.Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds.Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

    His quick mastery of quantum mechanics earned him a place at Los Alamos working on the Manhattan Project under J. Robert Oppenheimer, where the giddy young man held his own among the nation’s greatest minds. There, Feynman turned theory into practice, culminating in the Trinity test, on July 16, 1945, when the Atomic Age was born. He was only twenty-seven. And he was just getting started. In this sweeping biography, James Gleick captures the forceful personality of a great man, integrating Feynman’s work and life in a way that is accessible to laymen and fascinating for the scientists who follow in his footsteps.

    A vivid and eloquent book." --Stephen W. Sears, author of Gettysburg"Little Round Top has become iconic in Civil War literature and American memory. In the emotional recollection of our great war, if there was one speck on the landscape that decided a battle and the future of a nation, then surely this was it. The story of the July 2, 1863 struggle for that hill outside Gettysburg goes deeper into our consciousness than that, however. The men who fought for it then and there believed it to be decisive, and that is why they died for it. Glenn W. LaFantasie's Twilight at Little Round Top addresses that epic struggle, how those warriors felt then and later, and their physical and emotional attachment to a piece of ground that linked them forever with their nation's fate. This is military and social history at its finest." --W.C. Davis, author of Lincoln's Men and An Honorable Defeat"Few military episodes of the Civil War have attracted as much attention as the struggle for Little Round Top on the second day of Gettysburg. This judicious and engaging book navigates confidently through a welter of contradictory testimony to present a splendid account of the action. It also places events on Little Round Top, which often are exaggerated, within the broader sweep of the battle. All readers interested in the battle of Gettysburg will read this book with enjoyment and profit." --Gary W. Gallagher, author of The Confederate War"In his beautifully written narrative, Glenn LaFantasie tells the story of the battle for Little Round Top from the perspective of the soldiers who fought and died in July 1863. Using well-chosen quotes from a wide variety of battle participants, TWILIGHT puts the reader in the midst of the fight--firing from behind boulders with members of the 4th Alabama, running up the hillside into battle with the men of the 140th New York, and watching in horror as far too many men die. This book offers an elegy to the courage of those men, a meditation on the meaning of war, and a cautionary tale about the sacrifices nations ask of their soldiers and the causes for which those sacrifices are needed." --Amy Kinsel, Winnrer of the 1993 Allan Nevins Prize for From These Honored Dead: Gettysburg in American Culture

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Now with a new afterword describing the security lapses that preceded the attacks of September 11, 2001, Body of Secrets takes us to the inner sanctum of America’s spy world. In the follow-up to his bestselling Puzzle Palace, James Banford reveals the NSA’s hidden role in the most volatile world events of the past, and its desperate scramble to meet the frightening challenges of today and tomorrow.Here is a scrupulously documented account–much of which is based on unprecedented access to previously undisclosed documents–of the agency’s tireless hunt for intelligence on enemies and allies alike. Body of secrets is a riveting analysis of this most clandestine of agencies, a major work of history and investigative journalism.

    More than a possibility, it is becoming a necessity: whether our hand is forced by climate change and resource depletion or whether future catastrophes compel us to abandon Earth, one day we will make our homes among the stars.World-renowned physicist and futurist Michio Kaku explores in rich, accessible detail how humanity might gradually develop a sustainable civilization in outer space. With his trademark storytelling verve, Kaku shows us how science fiction is becoming reality: mind-boggling developments in robotics, nanotechnology, and biotechnology could enable us to build habitable cities on Mars; nearby stars might be reached by microscopic spaceships sailing through space on laser beams; and technology might one day allow us to transcend our physical bodies entirely.With irrepressible enthusiasm and wonder, Dr. Kaku takes readers on a fascinating journey to a future in which humanity could finally fulfil its long-awaited destiny among the stars - and perhaps even achieve immortality.

    Suvorov explains his view on the political realities of the USSR, where everything is subordinated to maintain the Communist regime's dominance, thus explaining the rationale behind Soviet strategic planning. He then goes on to explain the organisation of the Soviet armed forces, from the top down, emphasizing the Land Forces/Soviet Army. Technical details are presented where useful, but the primary concern is explaining the underlying philosophy and culture, often contrasted with the Western military approach. Suvorov then concludes with descriptions of the daily life inside the Soviet Army for the soldier and the officer, including the bullying and hazing practice known as dedovshchina, a practice then almost unknown to the West at the time of publication, which has become notorious in the Russian Ground Forces of the post-Soviet period.

    In 1905 an unknown 26-year-old clerk at the Swiss Patent Office, who had supposedly failed math in school, burst on to the scientific scene and swept away the hidebound theories of the day. The clerk, Albert Einstein, introduced a new and unexpected understanding of the universe and launched the two great revolutions of twentieth-century physics, relativity and quantum mechanics. The obscure origin and wide-ranging brilliance of the work recalled Isaac Newton’s “annus mirabilis” (miracle year) of 1666, when as a 23-year-old seeking safety at his family manor from an outbreak of the plague, he invented calculus and laid the foundations for his theory of gravity. Like Newton, Einstein quickly became a scientific icon--the image of genius and, according to Time magazine, the Person of the Century.The actual story is much more interesting. Einstein himself once remarked that “science as something coming into being ... is just as subjectively, psychologically conditioned as are all other human endeavors.” In this profile, the historian of science L. Randles Lagerstrom takes you behind the myth and into the very human life of the young Einstein. From family rifts and girlfriend troubles to financial hardships and jobless anxieties, Einstein’s early years were typical of many young persons. And yet in the midst of it all, he also saw his way through to profound scientific insights. Drawing upon correspondence from Einstein, his family, and his friends, Lagerstrom brings to life the young Einstein and enables the reader to come away with a fuller and more appreciative understanding of Einstein the person and the origins of his revolutionary ideas.About the cover image: While walking to work six days a week as a patent clerk in Bern, Switzerland, Einstein would pass by the famous "Zytglogge" tower and its astronomical clocks. The daily juxtaposition was fitting, as the relative nature of time and clock synchronization would be one of his revolutionary discoveries in the miracle year of 1905.

    This classic biography carefully traces Bukharin's rise to and fall from power, focusing particularly on the development of his theories and programmatic ideas during the critical period between Lenin's death in 1924 and the ascendancy of Stalin in 1929.

    Kropotkin based this classic on his observations of natural phenomena and history, forming a work of stunning and well-reasoned scholarship. Essential to the understanding of human evolution as well as social organization, it offers a powerful counterpoint to the tenets of Social Darwinism. It also cites persuasive evidence of human nature's innate compatibility with anarchist society."Kropotkin's basic argument is correct," noted evolutionary biologist Stephen Jay Gould. "Struggle does occur in many modes, and some lead to cooperation among members of a species as the best pathway to advantage for individuals." Anthropologist Ashley Montagu declared that "Mutual Aid will never be any more out of date than will the Declaration of Independence. New facts may increasingly become available, but we can already see that they will serve largely to support Kropotkin's conclusion that 'in the ethical progress of man, mutual support—not mutual struggle—has had the leading part.'" Physician and author Alex Comfort asserted that "Kropotkin profoundly influenced human biology by his theory of Mutual Aid. . . . He was one of the first systematic students of animal communities, and may be regarded as the founder of modern social ecology."

    In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires. At the heart of the story are Thomas Alva Edison, the nation’s most famous and folksy inventor, creator of the incandescent light bulb and mastermind of the world’s first direct current electrical light networks; the Serbian wizard of invention Nikola Tesla, elegant, highly eccentric, a dreamer who revolutionized the generation and delivery of electricity; and the charismatic George Westinghouse, Pittsburgh inventor and tough corporate entrepreneur, an industrial idealist who in the era of gaslight imagined a world powered by cheap and plentiful electricity and worked heart and soul to create it. Edison struggled to introduce his radical new direct current (DC) technology into the hurly-burly of New York City as Tesla and Westinghouse challenged his dominance with their alternating current (AC), thus setting the stage for one of the eeriest feuds in American corporate history, the War of the Electric Currents. The battlegrounds: Wall Street, the 1893 Chicago World’s Fair, Niagara Falls, and, finally, the death chamber - Jonnes takes us on the tense walk down a prison hallway and into the sunlit room where William Kemmler, convicted ax murderer, became the first man to die in the electric chair. Empires of Light is the gripping history of electricity, the “mysterious fluid,” and how the fateful collision of Edison, Tesla, and Westinghouse left the world utterly transformed.

    The atomic bombs that came out of it brought an end to the war in the Pacific, but at a heavy loss of life in Japan and the opening of a Pandora's box that has tested international relations.This book traces the history of the Manhattan Project, from the first glimmerings of the possibility of such a catastrophic weapon to the aftermath of the bombings of Hiroshima and Nagasaki. It profiles the architects of the bomb and how they tried to reconcile their personal feelings with their ambition as scientists. It looks at the role of the politicians and it includes first-hand accounts of those who experienced the effects of the bombings.

    Yet, as the 1700s began, the mysteries of the universe were pondered by "natural philosophers"—the term "scientist" didn't even exist until the mid 19th century—whose explanations couldn't help but be influenced by the religious thought and political and social contexts that shaped their world.The radical ideas of the Enlightenment were especially important and influential. In this course you see how the work of these natural philosophers prepared the way for the more familiar world of science we recognize today.

    From bone-whittling microgravity to eye-popping profits, the risks and rewards of space settlement have never been so close at hand.More than fifty years after the Apollo 11 moon landing, why is there so little human presence in space? Will we ever reach Mars? What will it take to become a multiplanet species, colonizing the solar system and traveling to other stars?Spacefarers meets these questions head on. While many books have speculated on the possibility of living beyond the Earth, few have delved into the practical challenges or plausible motives for leaving the safe confines of our home planet. Christopher Wanjek argues that there is little doubt we will be returning to the Moon and exploring Mars in the coming decades, given the potential scientific and commercial bonanza. Private industry is already taking a leading role and earning profits from human space activity. This can be, Wanjek suggests, a sustainable venture and a natural extension of earthbound science, business, and leisure. He envisions hotels in low-earth orbit and mining, tourism, and science on the Moon. He also proposes the slow, steady development of science bases on Mars, to be followed by settlements if Martian gravity will permit reproduction and healthy child development.An appetite for wonder will take us far, but if we really want to settle new worlds, we'll need the earnest plans of engineers, scientists, and entrepreneurs. Wanjek introduces us to those planners, who are striving right now to make life in space a reality.
