His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    The chafing restrictions of a typical upbringing in upper-class, small town Alabama simply did not apply to Zelda, who was described as an unusual child and permitted to roam the streets with little supervision. Zelda refused to blossom into a typical 'Southern belle' on anyone's terms but her own and while still in high school enjoyed the status of a local celebrity for her shocking behavior. Everybody in town knew the name Zelda Sayre. Queen of the Montgomery social scene, Zelda had a different beau ready and willing to show her a good time for every day of the week. Before meeting F. Scott Fitzgerald, Zelda's life was a constant pursuit of pleasure. With little thought for the future and no responsibilities to speak of, Zelda committed herself fully to the mantra that accompanied her photo in her high school graduation book: "Why should all life be work, when we all can borrow. Let's think only of today, and not worry about tomorrow." But for now Zelda was still in rehearsal for her real life to begin, a life she was sure would be absolutely extraordinary. Zelda Sayre married F. Scott Fitzgerald on the 3rd of April 1920 and left sleepy Montgomery behind in order to dive headfirst into the shimmering, glamourous life of a New York socialite. With the publication of Scott's first novel, This Side of Paradise, Zelda found herself thrust into the limelight as the very epitome of the Flapper lifestyle. Concerned chiefly with fashion, wild parties and flouting social expectations, Zelda and Scott became icons of the Jazz Age, the personification of beauty and success. What Zelda and Scott shared was a romantic sense of self-importance that assured them that their life of carefree leisure and excess was the only life really worth living. Deeply in love, the Fitzgeralds were like to sides of the same coin, each reflecting the very best and worst of each other. While the world fell in love with the image of the Fitzgeralds they saw on the cover of magazines, behind the scenes the Fitzgerald's marriage could not withstand the tension of their creative arrangement. Zelda was Scott's muse and he mercilessly mined the events of their life for material for his books. Scott claimed Zelda's memories, things she said, experiences she had and even passages from her diary as his possessions and used them to form the basis of his fictional works. Zelda had a child but the domestic sphere offered no comfort or purpose for her. The Flapper lifestyle was not simply a phase she lived through, it formed the very basis of her character and once the parties grew dull, the Fitzgeralds' drinking became destructive and Zelda's beauty began to fade, the world held little allure for her. Zelda sought reprieve in work and tried to build a career as a ballet dancer. When that didn't work out she turned to writing but was forbidden by Scott from using her own life as material. Convinced that she would never leave her mark on the world as deeply or expressively as Scott had, Zelda retreated into herself and withdrew from the people she knew in happier times. The later years of Zelda's life were marred by her detachment from reality as, diagnosed with schizophrenia, Zelda spent the last eighteen years of her life living in and out of psychiatric hospitals. As Scott's life unraveled due to alcohol abuse, Zelda looked back on the years they had spent together, young and wild and beautiful, as the best of her life. She may have been right but she was wrong about one thing, Zelda did leave her mark on the world and it was a deep and expressive mark that no one could have left but her. Zelda Fitzgerald: The Biography

    We wouldn’t have unraveled DNA or discovered Neptune or figured out how to put 5,000 songs in your pocket. Though many of us were scared away from this essential, engrossing subject in high school and college, Steven Strogatz’s brilliantly creative, down‑to‑earth history shows that calculus is not about complexity; it’s about simplicity. It harnesses an unreal number—infinity—to tackle real‑world problems, breaking them down into easier ones and then reassembling the answers into solutions that feel miraculous. Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves (a phenomenon predicted by calculus). Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes “backwards” sometimes; how to make electricity with magnets; how to ensure your rocket doesn’t miss the moon; how to turn the tide in the fight against AIDS. As Strogatz proves, calculus is truly the language of the universe. By unveiling the principles of that language, Infinite Powers makes us marvel at the world anew.

    

    Like William Clarke Quantrill and "Bloody Bill" Anderson, Samuel Hildebrand was a proud Missouri bushwhacker. In this long out of print book, Hildebrand describes raids and executions his band of men carried out. He remained at the end of the war and unreconstructed rebel and fervent racist. Like many of his southern brethren who fought, he never owned slaves but kept a captured black man with him after the war. This self-serving but fascinating account is a valuable addition to the canon of Civil War literature. In it, Hildebrand claims that others have tried to tell his story but have gotten it wrong, so he has a notarized statement by prominent men included as verification of authenticity. Every memoir of the American Civil War provides us with another view of the catastrophe that changed the country forever. For the first time ever, this long-out-of-print book is available as an affordable, well-formatted book for e-readers and smartphones. Be sure to LOOK INSIDE or download a sample.

    These special missions were called “Advanced Force Operations.” Subsequently, these special teams brought in the rest of the Green Berets during an operation called "the Ugly Baby." Then, one of the most significant battles in Special Forces history occurred: "Operation Viking Hammer," where six Green Beret teams along with a handful of CIA and Air Force Special Ops personnel, combined with approximately 8000 Peshmerga, took back hundreds of square kilometers from almost 1000 Ansar Al Islam extremists, and secured a poison production facility of national level significance. This book is the only firsthand account of these essential Unconventional Warfare operations, written by an operator who was there. In addition to describing these historically significant Special Operations missions, "One Green Beret" also details a 15-year career in the Green Berets that includes many unique experiences, such as joint operations alongside Russian Spetznaz on the northern border of Kosovo, and postwar operations in Bosnia embedded deeply with the locals. Mark Giaconia questions everything, and provides a VERY humble, sobering, and human perspective on war, military service, and strategic considerations. One Green Beret is very inspiring, and conveys the author’s personal evolution from gunslinger to educated computer scientist; a true tale of “post traumatic success.”

    Told through the eyes of a young girl, the book shares Gerda’s memories of Hitler’s rise to power and passionately describes the cruel toll that history can have on those who experience it. The book is much more than Gerda’s story. Through letters she received from her parents, who made the heartbreaking decision to send their two daughters to live with foster families in the relative safety of Holland, we learn how a mother and father try to raise a child from far away in times of great distress. Letters from them to Gerda’s foster parents, and desperate notes to an American family they hoped would act as sponsors, reveal their growing despair. The story is both deeply personal and universal as people wrestle with terrible choices to save their children and protect their families. These issues remain as relevant today as they were during the Holocaust. In 1939, while trying to arrange an escape from Germany, her parents sent 12-year-old Gerda and her younger sister to live with separate families in Holland, which was still safe for Jews. What was intended as a temporary move became permanent and Gerda never saw her parents again. Ultimately, she was the only member of her immediate family to survive and also had to bear the loss of the foster family she had come to love as her own. Gerda describes in searing detail her experiences in six concentration camps, her protection as a worker for the Philips Corporation, and her arrival in the U.S. in 1948 as an 18-year-old Holocaust survivor literally alone in the world. The memoir is a testament to the loving family Gerda built in America. Her husband added translations of the letters from her parents, grandparents and sister. After her oldest child and first grandchild were born, Gerda added notes to them. This group effort illustrates the special generational pull of trauma endured by Holocaust survivors.

    An unpopular war. A military and diplomatic team in disarray. Those are the challenges President Obama has faced as he attempts to make a success of U.S involvement in Afghanistan. They are also the challenges President Truman surmounted in the winter of 1950 as he began managing a war in Korea that risked becoming bigger and more costly. It was the first significant armed conflict of the Cold War: United States troops under the command of General Douglas MacArthur came to the aid of the South Koreans after North Korea invaded. When Communist China entered the conflict on the side of the North Koreans, the crisis seemed on the verge of flaring into a world war. Truman was determined not to let that happen. MacArthur kept urging a widening of the war into China itself and ignoring his Commander in Chief. On April 11, 1951, after MacArthur had “shot his mouth off,” as one diplomat put it, one too many times, Truman fired him. The story of their showdown—one of the most dramatic in U.S. history between a Commander in Chief and his top soldier in the field—is captured in all its detail by David McCullough in his biography Truman, and presented here in a e-book called Truman Fires MacArthur (an excerpt of Truman, McCullough’s Pulitzer Prize-winning biography), which was the headline carried in many newspapers around the country the next day. Truman Fires MacArthur will continue to ride the headlines. It will go on sale as an ebook just as the Rolling Stone profile that exposed General Stanley McChrystal’s insurrection and forced his resignation hits newsstands, and media coverage of the showdown continues to draw historical analogies between Truman and Obama.
