The conspirators were part of a pro-Southern secret society that didn’t want an anti-slavery President in the White House. They planned an elaborate scheme to assassinate the brand new President in a Baltimore train station as Lincoln’s inauguration train passed through en route to the Capital. The plot was investigated by famed detective Allan Pinkerton, who infiltrated the group with undercover agents, including one of the first female private detectives in America. Had the assassination succeeded, there would have been no Lincoln Presidency, and the course of the Civil War and American history would have forever been altered.The bestselling team that brought you The First Conspiracy now turns their attention to the story of the secret society that tried to kill Abraham Lincoln and the undercover detectives who foiled their plans.

    Throughout this fascinating book, Clifford Pickover invites us to share in the amazing adventures of brilliant, quirky, and passionate people after whom these laws are named. These lawgivers turn out to be a fascinating, diverse, and sometimes eccentric group of people. Many were extremely versatile polymaths--human dynamos with a seemingly infinite supply of curiosity and energy and who worked in many different areas in science. Others had non-conventional educations and displayed their unusual talents from an early age. Some experienced resistance to their ideas, causing significant personal anguish. Pickover examines more than 40 great laws, providing brief and cogent introductions to the science behind the laws as well as engaging biographies of such scientists as Newton, Faraday, Ohm, Curie, and Planck. Throughout, he includes fascinating, little-known tidbits relating to the law or lawgiver, and he provides cross-references to other laws or equations mentioned in the book. For several entries, he includes simple numerical examples and solved problems so that readers can have a hands-on understanding of the application of the law. A sweeping survey of scientific discovery as well as an intriguing portrait gallery of some of the greatest minds in history, this superb volume will engage everyone interested in science and the physical world or in the dazzling creativity of these brilliant thinkers.

    In this narrative, Walter Isaacson explains how his mind worked and the mysteries of the universe that he discovered.

    Doron Swade, technology historian and assistant director of London's Science Museum, investigates the troubles that plagued 19th-century knowledge engineers in The Difference Engine: Charles Babbage and the Quest to Build the First Computer.The author is in a unique position to appreciate the technical difficulties of the time, as he led a team that built a working model of a Difference Engine, using contemporary materials, in time for Babbage's 1991 bicentenary. The meat of the book is comprised of the story of the first computing machine design as gathered from the technical notes and drawings curated by Swade. Though Babbage certainly had problems translating his ideas into brass, the reader also comes to understand his fruitless, drawn-out arguments with his funders. Swade had it comparatively easy, though his depictions of the frustrating search for money and then working out how best to build the enormous machine in the late 1980s are delightful.It is difficult--maybe impossible--to draw a clear, unbroken line of influence from Babbage to any modern computer researchers, but his importance both as the first pioneer and as a symbol of the joys and sorrows of computing is unquestioned. Swade clearly respects his subject deeply, all the more so for having tried to bring the great old man's ideas to life. The Difference Engine is lovingly comprehensive and will thrill readers looking for a more technical examination of Babbage's career. --Rob Lightner

    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    Johnson takes us to those times when the world seemed filled with mysterious forces, when scientists were dazzled by light, by electricity, and by the beating of the hearts they laid bare on the dissecting table. We see Galileo singing to mark time as he measures the pull of gravity, and Newton carefully inserting a needle behind his eye to learn how light causes vibrations in the retina. William Harvey ties a tourniquet around his arm and watches his arteries throb above and his veins bulge below, proving that blood circulates. Luigi Galvani sparks electrical currents in dissected frog legs, wondering at the twitching muscle fibers, and Ivan Pavlov makes his now-famous dogs salivate at ascending chord progressions.For all of them, diligence was rewarded. In an instant, confusion was swept aside and something new about nature leaped into view. In bringing us these stories, Johnson restores some of the romance to science, reminding us of the existential excitement of a single soul staring down the unknown.

    But now, with the aid of high-speed computers, scientists have been able to penetrate a reality that is changing the way we perceive the universe. Their findings -- the basis for chaos theory -- represent one of the most exciting scientific pursuits of our time.No better introduction to this find could be found than John Briggs and F. David Peat's Turbulent Mirror. Together, they explore the many faces of chaos and reveal how its law direct most of the processes of everyday life and how it appears that everything in the universe is interconnected -- discovering an "emerging science of wholeness."Turbulent Mirror introduces us to the scientists involved in study this endlessly strange field; to the theories that are turning our perception of the world on its head; and to the discoveries in mathematics, biology, and physics that are heralding a revolution more profound than the one responsible for producing the atomic bomb. With practical applications ranging from the control of traffic flow and the development of artifical intelligence to the treatment of heart attacks and schizophrenia, chaos promises to be an increasingly rewarding area of inquiry -- of interest to everyone.

    Kennedy, as told by the Secret Service agents who were firsthand witnesses to one of America’s greatest tragedies.The Secret Service. An elite team of men who share a single mission: to protect the president of the United States. On November 22, 1963, these men failed—and a country would never be the same. Now, for the first time, a member of JFK’s Secret Service detail reveals the inside story of the assassination, the weeks and days that led to it and its heartrending aftermath. This extraordinary book is a moving, intimate portrait of dedication, courage, and loss. Drawing on the memories of his fellow agents, Jerry Blaine captures the energetic, crowd-loving young president, who banned agents from his car and often plunged into raucous crowds with little warning. He describes the careful planning that went into JFK’s Texas swing, the worries and concerns that agents, working long hours with little food or rest, had during the trip. And he describes the intensely private first lady making her first-ever political appearance with her husband, just months after losing a newborn baby. Here are vivid scenes that could come only from inside the Kennedy detail: JFK’s last words to his tearful son when he left Washington for the last time; how a sudden change of weather led to the choice of the open-air convertible limousine that day; Mrs. Kennedy standing blood-soaked outside a Dallas hospital room; the sudden interruption of six-year-old Caroline’s long-anticipated sleepover with a friend at home; the exhausted team of agents immediately reacting to the president’s death with a shift to LBJ and other key governmental figures; the agents’ dismay at Jackie’s decision to walk openly from the White House to St. Matthew’s Cathedral at the state funeral. Most of all, this is a look into the lives of men who devoted their entire beings to protecting the presidential family: the stress of the secrecy they kept, the emotional bonds that developed, the terrible impact on agents’ psyches and families, and their astonishment at the country’s obsession with far-fetched conspiracy theories and finger-pointing. A book fifty years in coming, The Kennedy Detail is a portrait of incredible camaraderie and incredible heartbreak—a true, must-read story of heroism in its most complex and human form.

    But it would take the world some time to believe what had happened: the age of flight had begun, with the first heavier-than-air, powered machine carrying a pilot.Who were these men and how was it that they achieved what they did?David McCullough, two-time winner of the Pulitzer Prize, tells the surprising, profoundly American story of Wilbur and Orville Wright.Far more than a couple of unschooled Dayton bicycle mechanics who happened to hit on success, they were men of exceptional courage and determination, and of far-ranging intellectual interests and ceaseless curiosity, much of which they attributed to their upbringing. The house they lived in had no electricity or indoor plumbing, but there were books aplenty, supplied mainly by their preacher father, and they never stopped reading.When they worked together, no problem seemed to be insurmountable. Wilbur was unquestionably a genius. Orville had such mechanical ingenuity as few had ever seen. That they had no more than a public high school education, little money and no contacts in high places, never stopped them in their mission to take to the air. Nothing did, not even the self-evident reality that every time they took off in one of their contrivances, they risked being killed.In this thrilling book, master historian David McCullough draws on the immense riches of the Wright Papers, including private diaries, notebooks, scrapbooks, and more than a thousand letters from private family correspondence to tell the human side of the Wright Brothers' story, including the little-known contributions of their sister, Katharine, without whom things might well have gone differently for them.
