The story of Stephen Hawking's relentless quest for the secret of the origins of the universe will change forever the way you look at the stars . . . and your place among them.

    He revolutionized the field of topology, which studies properties of geometric configurations that are unchanged by stretching or twisting. The Poincare conjecture lies at the heart of modern geometry and topology, and even pertains to the possible shape of the universe. The conjecture states that there is only one shape possible for a finite universe in which every loop can be contracted to a single point.Poincare's conjecture is one of the seven "millennium problems" that bring a one-million-dollar award for a solution. Grigory Perelman, a Russian mathematician, has offered a proof that is likely to win the Fields Medal, the mathematical equivalent of a Nobel prize, in August 2006. He also will almost certainly share a Clay Institute millennium award.In telling the vibrant story of The Poincare Conjecture, Donal O'Shea makes accessible to general readers for the first time the meaning of the conjecture, and brings alive the field of mathematics and the achievements of generations of mathematicians whose work have led to Perelman's proof of this famous conjecture.

    D. Smith's personal memoir of his years in naval aviation is more than a ‘I was there’ tale. He captures the myriad of challenges that was Naval Aviation before the Vietnam War. When I arrived in the fleet, D. D. Smith and his compadres were the squadron execs or COs who led us nuggets into the inferno of Vietnam… A huge tip of the hat to D.D. Smith. This book will appeal to every naval aviator or NFO of whatever era. Highly recommended.” But the book is much more. It is a cleverly written and refreshingly honest story of the author’s life and times as he fights his way from rural Minnesota to the blazing skies over North Vietnam. Commander Smith flew 138 combat missions and made more than 800 carrier arrested landings. As the Navy’s first Chief Test Pilot, his tests in the F-14 led to the first EVER flat spin in a Tomcat – and it nearly killed him. No swaggering bravado here; this is a fresh, insightful look at life, luck and guts – in Vietnam and beyond.

    It may hide additional dimensions of space other than the familier three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now.Warped Passages is a brilliantly readable and altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature—taking us into the warped, hidden dimensions underpinning the universe we live in, demystifying the science of the myriad worlds that may exist just beyond our own.

    Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles.This completely new translation, the first in 270 years, is based on the third (1726) edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system.The illuminating Guide to the Principia by I. Bernard Cohen, along with his and Anne Whitman's translation, will make this preeminent work truly accessible for today's scientists, scholars, and students.

    Bernard Haisch contends that there is a purpose and an underlying intelligence behind the Universe, one that is consistent with modern science, especially the Big Bang and evolution. It is based on recent discoveries that there are numerous coincidences and fine-tunings of the laws of nature that seem extraordinarily unlikely.A more rational concept of God is called for. As astrophysicist Sir James Jeans wrote, "the Universe begins to look more like a great thought than like a great machine."Despite bestsellers by Christopher Hitchens, Richard Dawkins, and Sam Harris that have denounced the evils of religion and proclaimed that science has shown that there is no God, The Purpose-Guided Universe shows how one can believe in God and science.

    One held that the entire universe was contained in the Milky Way galaxy. Their champion was the strong-willed astronomer Harlow Shapley. Another camp believed that the universe was so vast that the Milky Way was just one galaxy among billions—the view that would prevail, proven by the equally headstrong Edwin Hubble.Almost forgotten is the Harvard Observatory "computer"—a human number cruncher hired to calculate the positions and luminosities of stars in astronomical photographs—who found the key to the mystery. Radcliffe-educated Henrietta Swan Leavitt, fighting ill health and progressive deafness, stumbled upon a new law that allowed astronomers to use variable stars—those whose brightness rhythmically changes—as a cosmic yardstick. Miss Leavitt's Stars is both a masterly account of how we measure the universe and the moving story of a neglected genius

    But a dispute over its discovery sowed the seeds of discontent between two of the greatest scientific giants of all time - Sir Isaac Newton and Gottfried Wilhelm Leibniz." "Today Newton and Leibniz are generally considered the twin independent inventors of calculus. They are both credited with giving mathematics its greatest push forward since the time of the Greeks. Had they known each other under different circumstances, they might have been friends. But in their own lifetimes, the joint glory of calculus was not enough for either and each declared war against the other, openly and in secret." This long and bitter dispute has been swept under the carpet by historians - perhaps because it reveals Newton and Leibniz in their worst light - but The Calculus Wars tells the full story in narrative form for the first time. This history ultimately exposes how these twin mathematical giants were brilliant, proud, at times mad, and in the end completely human.

    Shirer's new book - written in his ninth decade - explores the passionate, highly charged, and extraordinary lives of Leo and Sonya Tolstoy. It is a compelling illumination both of the nature of genius and of the universal problems of love, sex, and marriage - themes that Tolstoy played out in his great fiction and that haunted him in his tangled domestic life. Rich in anecdotes, wise, full of sweeping history, and imbued with Shirer's profound knowledge of literature and life, Love and Hatred ranks beside such works as Robert Massie's Nicholas and Alexandra and Nigel Nicolson's Portrait of a Marriage as a masterly, intuitive, and sympathetic exploration of the love/hate relationship between two famous, bigger-than-life people. Beginning in 1862, when Tolstoy committed the blunder of asking his young bride to read his diaries of his bachelor life so there should be no secrets between them, and ending with his tragic flight from home (and marriage) in 1910 while the whole world waited for news of him, Love and Hatred tells the story of a great romance between two people who could live neither together nor apart - a romance that exhausted and obsessed them both, and that forms the basis for much of Tolstoy's work. The final book of William L. Shirer's long and brilliant career, it is - appropriately - a masterly re-creation of a time, of two extraordinary people, and of the very nature of love, marriage, and old age.

    From the theoretical discussions of nuclear energy to the bright glare of Trinity there was a span of hardly more than twenty-five years. What began as merely an interesting speculative problem in physics grew into the Manhattan Project, and then into the Bomb with frightening rapidity, while scientists known only to their peers -- Szilard, Teller, Oppenheimer, Bohr, Meitner, Fermi, Lawrence, and yon Neumann -- stepped from their ivory towers into the limelight.Richard Rhodes takes us on that journey step by step, minute by minute, and gives us the definitive story of man's most awesome discovery and invention.

    In this simple pattern beginning with two ones, each succeeding number is the sum of the two numbers immediately preceding it (1, 1, 2, 3, 5, 8, 13, 21, ad infinitum). Far from being just a curiosity, this sequence recurs in structures found throughout nature - from the arrangement of whorls on a pinecone to the branches of certain plant stems. All of which is astounding evidence for the deep mathematical basis of the natural world. With admirable clarity, two veteran math educators take us on a fascinating tour of the many ramifications of the Fibonacci numbers. They begin with a brief history of a distinguished Italian discoverer, who, among other accomplishments, was responsible for popularizing the use of Arabic numerals in the West. Turning to botany, the authors demonstrate, through illustrative diagrams, the unbelievable connections between Fibonacci numbers and natural forms (pineapples, sunflowers, and daisies are just a few examples). In art, architecture, the stock market, and other areas of society and culture, they point out numerous examples of the Fibonacci sequence as well as its derivative, the "golden ratio." And of course in mathematics, as the authors amply demonstrate, there are almost boundless applications in probability, number theory, geometry, algebra, and Pascal's triangle, to name a few.Accessible and appealing to even the most math-phobic individual, this fun and enlightening book allows the reader to appreciate the elegance of mathematics and its amazing applications in both natural and cultural settings.

    And the humanitarianism took place during the heat of the battle. The GI fixed as he fought, he cured and educated and built in the middle of the battle. He truly cared for, and about, those people. What other Army has ever done that? Humanitarianism was America's great victory in Viet Nam. Spearheading the humanitarian efforts were the air ambulance operations, call-sign Dust Off, the most dangerous of all aviation operations, which rescued some one million souls in Viet Nam. Dead Men Flying is the story of Charles Kelly, the father of Dust Off, who gave his life to save Dust Off -- the greatest life-saver ever. His dying words -- "When I have your wounded" -- set the standard for combat medicine to this day. It is also the story of the author, Medal of Honor recipient General Patrick Brady, who learned from Charles Kelly and struggled to meet his standard. Brady led the 54th Medical Detachment as it rescued over 21,000 wounded -- enemy and friendly -- in 10 months, while sustaining 26 Purple Hearts. Finally, Dead Men Flying is the story of salvation in the midst of horror, courage in the face of adversity, and the miracle of faith in the heat of combat. A riveting tale from America's most decorated living soldier, this is a book that no American can afford to ignore.

    The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit.Now with the advent of a revolutionary new plan, all this has changed. leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes.The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars--a process that can alter the atmosphere of planets and pave the way for sustainable life.

    It remains the one of the most widely read books about science to come out of the twentieth century.(Note: the book was first published in 1934, in German, with the title Logik der Forschung. It was "reformulated" into English in 1959. See Wikipedia for details.)
