This country house was home to Britain's most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology—indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the scientists and the codebreaking, fictional and non-fiction—from Robert Harris and Ian McEwan to Andrew Hodges' biography of Turing—what of the thousands of men and women who lived and worked there during the war? The first history for the general reader of life at Bletchley Park, this is also an amazing compendium of memories from people now in their eighties of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in), of a youthful Roy Jenkins—useless at codebreaking, of the high jinks at nearby accommodation hostels, and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other's work.

    Under their sultan, Solyman the Magnificent, the Turks had conquered most of Eastern Europe. The rulers of Christian Europe were at their wits' end to stem the tide of disaster. The Knights of St John, the fighting religious order drawn from most of the nations of Christendom had been driven from their island fortress of Rhodes 40 years earlier. From their new base of Malta their galleys had been so successful in their raids on Turkish shipping that the Sultan realised that only they stood between him and total mastery of the Mediterranean. He determined to obliterartethe Knights of Malta.

    Relativity and quantum physics touch the very basis of physical reality, altering our commonsense notions of space and time, cause and effect. Both have reputations for complexity. But the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion. The same goes for quantum theory, which is based on the principle that the "stuff " of the universe-matter and energy-is not infinitely divisible but comes in discrete chunks called "quanta." Profound ... Beautiful ... Relevant Why should you care about these landmark theories? Because relativity and quantum physics are not only profound and beautiful ideas in their own right, they are also the gateway to understanding many of the latest science stories in the media. These are the stories about time travel, string theory, black holes, space telescopes, particle accelerators, and other cutting-edge developments. Consider these ideas: Although Einstein's theory of general relativity dates from 1914, it has not been possible to test certain predictions until recently. The Hubble Space Telescope is providing some of the most striking confirmations of the theory, including certain evidence for the existence of black holes, objects that warp space and time so that not even light can escape. Also, the expansion of the universe predicted by the theory of general relativity is now a known rate. General relativity also predicts an even weirder phenomenon called "wormholes" that offer shortcuts to remote reaches of time and space. According to Einstein's theory of special relativity, two twins would age at different rates if one left on a high-speed journey to a distant star and then returned. This experiment has actually been done, not with twins, but with an atomic clock flown around the world. Another fascinating experiment confirming that time slows as speed increases comes from measuring muons at the top and bottom of mountains. A seemingly absurd consequence of quantum mechanics, called "quantum tunneling," makes it possible for objects to materialize through impenetrable barriers. Quantum tunneling happens all the time on the subatomic scale and plays an important role in electronic devices and the nuclear processes that keep the sun shining. Some predictions about the expansion of the universe were so odd that Einstein himself tried to rewrite the mathematics in order to eliminate them. When Hubble discovered the expansion of the universe, Einstein called the revisions the biggest mistake he had ever made. An intriguing thought experiment called "Schrödinger's cat" suggests that a cat in an enclosed box is simultaneously alive and dead under experimental conditions involving quantum phenomena. From Aristotle to the Theory of Everything Professor Wolfson begins with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. Then he outlines the logic that led to Einstein's theory of special relativity, and the simple yet far-reaching insight on which it rests. With that insight in mind, you move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time. Professor Wolfson then shows how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so at odds with our experience that it nearly defies language. Bringing relativity and quantum mechanics into the same picture leads to hypotheses about the origin, development, and possible futures of the entire universe, and the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. Fascinating Incidents and Ideas Along the way, you'll explore these fascinating incidents and ideas: In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of the Earth relative to the ether, which was a supposedly imponderable substance pervading all of space. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis. In 1905, a young Swiss patent clerk named Albert Einstein resolved the crisis by discarding the ether concept and asserting the principle of relativity-that the laws of physics are the same for all observers in uniform motion. Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? And why does Einstein assert that nothing can go faster than light? Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for a whole day. Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime. Quantum theory places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation necessarily disturbs the thing that is being observed. The result is Werner Heisenberg's famous "uncertainty principle." Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Could they be manifestations of a single, universal force? A Teaching Legend On his own Middlebury College campus, Professor Wolfson is a teaching legend with an infectious enthusiasm for his subject and a knack for conveying difficult concepts in a way that fosters true understanding. He is the author of an introductory text on physics, a contributor to the esteemed publication Scientific American, and a specialist in interpreting science for the nonspecialist. In this course, Professor Wolfson uses extensive illustrations and diagrams to help bring to life the theories and concepts that he discusses. Thus we highly recommend our DVD version, although Professor Wolfson is mindful of our audio students and carefully describes visual materials throughout his lectures. Professor Richard Wolfson on the Second Edition of Einstein's Relativity: "The first version of this course was produced in 1995. In this new version, I have chosen to spend more time on the philosophical interpretation of quantum physics, and on recent experiments relevant to that interpretation. I have also added a final lecture on the theory of everything and its possible implementation through string theory. The graphic presentations for the DVD version have also been extensively revised and enhanced. But the goal remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson."

    In 1474, when most women were almost powerless, twenty-three-year-old Isabella defied a hostile brother and mercurial husband to seize control of Castile and León.Her subsequent feats were legendary. She ended a twenty-four-generation struggle between Muslims and Christians, forcing Moorish invaders back over the Mediterranean Sea. She laid the foundation for a unified Spain. She sponsored Columbus's trip to the Indies and negotiated Spanish control over much of the New World with the help of Rodrigo Borgia, the infamous Pope Alexander VI. She also annihilated all who stood against her by establishing a bloody religious Inquisition that would darken Spain's reputation for centuries.Whether saintly or satanic, no female leader has done more to shape our modern world, where millions of people in two hemispheres speak Spanish and practice Catholicism. Yet history has all but forgotten Isabella's influence, due to hundreds of years of misreporting that often attributed her accomplishments to Ferdinand, the bold and philandering husband she adored.Using new scholarship, Downey's luminous biography tells the story of this brilliant, fervent, forgotten woman, the faith that propelled her through life, and the land of ancient conflicts and intrigue she brought under her command.

    Ricks, a dual biography of Winston Churchill and George Orwell, whose farsighted vision and inspired action preserved democracy from the threats of authoritarianism, from the left and right alike.Both George Orwell and Winston Churchill came close to death in the mid-1930s—Orwell shot in the neck in a trench line in the Spanish Civil War, and Churchill struck by a car in New York City. If they'd died then, history would scarcely remember them. At the time, Churchill was a politician on the outs, his loyalty to his class and party suspect. Orwell was a mildly successful novelist, to put it generously. No one would have predicted that by the end of the 20th century they would be considered two of the most important people in British history for having the vision and courage to campaign tirelessly, in words and deeds, against the totalitarian threat from both the left and the right. In a crucial moment, they responded first by seeking the facts of the matter, seeing through the lies and obfuscations, and then acting on their beliefs. Together, to an extent not sufficiently appreciated, they kept the West's compass set toward freedom as its due north.It's not easy to recall now how lonely a position both men once occupied. By the late 1930s, democracy was discredited in many circles and authoritarian rulers were everywhere in the ascent. There were some who decried the scourge of communism, but saw in Hitler and Mussolini men we could do business with, if not in fact saviors. And there were others who saw the Nazi and fascist threat as malign but tended to view communism as the path to salvation. Churchill and Orwell, on the other hand, had the foresight to see clearly that the issue was human freedom—that whatever its coloration, a government that denied its people basic freedoms was a totalitarian menace and had to be resisted.In the end, Churchill and Orwell proved their age's necessary men. The glorious climax of Churchill and Orwell is the work they both did in the decade of the 1940s to triumph over freedom's enemies. And though Churchill played the larger role in the defeat of Hitler and the Axis, Orwell's reckoning with the menace of authoritarian rule in Animal Farm and 1984 would define the stakes of the Cold War for its 50-year course and continues to give inspiration to fighters for freedom to this day. Taken together, in Thomas E. Ricks' masterful hands, their lives are a beautiful testament to the power of moral conviction and to the courage it can take to stay true to it, through thick and thin.

    At the center of a triangle of Anglo Saxons, Vikings, and Normans all jostling for control of England, Emma was a political pawn who became an unscrupulous manipulator. Regarded by her contemporaries as a generous Christian patron, an admired regent, and a Machiavellian mother, Emma was, above all, a survivor: hers was a life marked by dramatic reversals of fortune, all of which she overcame.

    Professor Hans-Friedrich Mueller, of Union College in Schenectady, New York, makes this ancient world come alive in 24 lectures with captivating stories of intrigue, artifacts, illustrations, and detailed descriptions from primary sources of intriguing personalities. In the ancient Mediterranean area, religion was not separate from daily life. To the contrary, religion was daily life. The many dozen gods of this ancient world were everywhere, with spirits inhabiting every crack and crevice of life. These polytheists believed they had a strict contract with their deities: If they took care of their gods, their gods would take care of them (or at least not harm them). Consequently, they built extraordinary temples to honor their deities, brought food and wine to them, sacrificed animals for them, and held sacred meals with their gods. In fact, they followed numerous rules and regulations that circumscribed almost all aspects of life both inside and outside the home - anything and everything to keep the gods happy. Consequently, the religious practices of the ancient Mediterranean make a wonderful lens through which to develop a deeper understanding of their world.

    Why is Anne so compelling? Why has she inspired such extreme reactions? What did she really look like? Was she the flaxen-haired martyr of Romantic paintings or the raven-haired seductress of twenty-first century portrayals? (Answer: neither.) And perhaps the most provocative questions concern Anne's death more than her life. How could Henry order the execution of a once beloved wife? Drawing on scholarship and critical analysis, Susan Bordo probes the complexities of one of history's most infamous relationships.Bordo also shows how generations of polemicists, biographers, novelists, and filmmakers imagined and reimagined Anne: whore, martyr, cautionary tale, proto-"mean girl," feminist icon, and everything in between. In this lively book, Bordo steps off the well-trodden paths of Tudoriana to expertly tease out the human being behind the competing mythologies.

    In 1932, she began holding secret meetings in her apartment — a small band of political activists that by 1940 had grown into the largest underground resistance group in Berlin. She recruited working-class Germans into the resistance, helped Jews escape, plotted acts of sabotage, and collaborated in writing leaflets that denounced Hitler and called for revolution. Her co-conspirators circulated through Berlin under the cover of night, slipping the leaflets into mailboxes, public restrooms, phone booths. When the first shots of the Second World War were fired, she became a spy, couriering top-secret intelligence to the Allies. On the eve of her escape to Sweden, she was ambushed by the Gestapo. At a Nazi military court, a panel of five judges sentenced her to six years at a prison camp, but Hitler overruled the decision and ordered her execution. On February 16, 1943, she was strapped to a guillotine and beheaded.Historians identify Mildred Harnack as the only American in the leadership of the German resistance, yet her remarkable story has remained almost unknown until now.Harnack’s great-great-niece Rebecca Donner draws on her extensive archival research in Germany, Russia, England, and the U.S. as well as newly uncovered documents in her family archive to produce this astonishing work of narrative nonfiction. Fusing elements of biography, real-life political thriller, and scholarly detective story, Donner brilliantly interweaves letters, diary entries, notes smuggled out of a Berlin prison, survivors’ testimony, and a trove of declassified intelligence documents into a powerful, epic story, reconstructing the moral courage of an enigmatic woman nearly erased by history.

    His wife, Marguerite, has accused squire Jacques Le Gris of rape. A deadlocked court decrees a “trial by combat” between the two men that also leaves Marguerite’s fate in the balance. For if her husband loses the duel, she will be put to death as a false accuser. While enemy troops pillage the land, and rebellion and plague threaten the lives of all, Carrouges and Le Gris meet in full armor on a walled field in Paris. What follows is a fierce duel, the final one sanctioned by governing powers, before a massive crowd that includes the teenage King Charles VI, during which both combatants are wounded—but only one fatally.Based on extensive research in Normandy and Paris, THE LAST DUEL brings to life a colorful, turbulent age and three unforgettable characters caught in a fatal triangle of crime, scandal, and revenge. THE LAST DUEL is at once a moving human drama, a captivating true crime story, and an engrossing work of historical intrigue with themes that echo powerfully centuries later.

    He’s had a pretty bad press: supposed usurper of Richard II’s crown and the focus of hatred in the Peasants’ Revolt (they torched his home, the Savoy Palace). Helen Carr will paint a complex portrait of a man who held the levers of power on the English and European stage, passionately upheld chivalric values, pressed for the Bible to be translated into English, patronised the arts … and, if you follow Shakespeare, gave the most beautiful oration on England (‘this sceptred isle… this blessed plot’). An engrossing drama of political machinations, violence, romance and tragedy played out at the cusp of a new era.

    Britain is at war. The horrors of blitzkrieg have seen one western European democracy after another fall in rapid succession to Nazi boot and shell. Invasion seems mere hours away. Just days after becoming Prime Minister, Winston Churchill must deal with this horror—as well as a skeptical King, a party plotting against him, and an unprepared public. Pen in hand and typist-secretary at the ready, how could he change the mood and shore up the will of a nervous people? In this gripping day-by-day, often hour-by-hour account of how an often uncertain Churchill turned Britain around, the celebrated Bafta-winning writer Anthony McCarten exposes sides of the great man never seen before. He reveals how he practiced and re-wrote his key speeches, from ‘Blood, toil, tears and sweat’ to ‘We shall fight on the beaches’; his consideration of a peace treaty with Nazi Germany, and his underappreciated role in the Dunkirk evacuation; and, above all, how 25 days helped make one man an icon. Using new archive material, McCarten reveals the crucial behind-the-scenes moments that changed the course of history. It’s a scarier—and more human—story than has ever been told. “McCarten's pulse-pounding narrative transports the reader to those springtime weeks in 1940 when the fate of the world rested on the shoulders of Winston Churchill. A true story thrillingly told. Thoroughly researched and compulsively readable.”—Michael F. Bishop, Executive Director of the International Churchill Society

    But, as Leanda de Lisle’s gripping new history reveals, they are a family still more extraordinary than the one we thought we knew.The Tudor canon typically starts with the Battle of Bosworth in 1485, before speeding on to Henry VIII and the Reformation. But this leaves out the family’s obscure Welsh origins, the ordinary man known as Owen Tudor who would fall (literally) into a Queen’s lap—and later her bed. It passes by the courage of Margaret Beaufort, the pregnant thirteen-year-old girl who would help found the Tudor dynasty, and the childhood and painful exile of her son, the future Henry VII. It ignores the fact that the Tudors were shaped by their past—those parts they wished to remember and those they wished to forget.By creating a full family portrait set against the background of this past, de Lisle enables us to see the Tudor dynasty in its own terms, and presents new perspectives and revelations on key figures and events. De Lisle discovers a family dominated by remarkable women doing everything possible to secure its future; shows why the princes in the Tower had to vanish; and reexamines the bloodiness of Mary’s reign, Elizabeth’s fraught relationships with her cousins, and the true significance of previously overlooked figures. Throughout the Tudor story, Leanda de Lisle emphasizes the supreme importance of achieving peace and stability in a violent and uncertain world, and of protecting and securing the bloodline.Tudor is bristling with religious and political intrigue but at heart is a thrilling story of one family’s determined and flamboyant ambition.
