    This is the life story of the atom bomb from its birth at the turn of the century to a childhood in the New Mexico desert of the 1940s, from early adulthood in Nagasaki to unsettling maturity in missile silos all over the globe.

    Written by Terry Lovelace, a 64 year-old lawyer and former assistant attorney general. In 2012 a routine x-ray of my leg found an anomalous bit of metal the size of a fingernail with two tiny wires attached. What followed were horrific nightmares, spontaneous recall and intrusive thoughts surrounding a 1977 camping trip I took with a friend to Devils Den State Park in Northern Arkansas. For fear of losing my job and my standing in the legal community I've kept this secret for 40 years. But the 2012 discovery of this object, one and one-half inches deep in my thigh, initiated a flood of nightmares I could not control. My poor health and the horrific memories were the catalyst to come forward and finally disclose what happened back in 1977. My friend and I were on a two-day camping trip to photograph eagles and wildlife. Rather than stay in the campground we chose to drive deep into an isolated area and set-up our camp on a high plateau that offered a scenic view of the wilderness. Late in the evening of our first night in camp a group of three very bright stars in the western sky caught our attention. Arranged in a triangle configuration we speculated as to what it could be? We eliminated aircraft lights due to the triangle configuration. Then it moved. The three stars rotated as if on an axis and slowly ascended upward. As it rose the three points of light spread apart, each equidistant to the others. The stars grew larger and brighter. As the triangle passed over stars they would blink-out for a moment and then blink-back again as it moved over them. The area inside the triangle was black, darker than the night sky. As the points expanded they were eventually devouring entire fields of stars as it traveled higher and moved closer to our camp. It eventually halted directly over us. It was huge. A third of the sky was covered by this black triangle overhead without a single star in between the three points. It was as if someone had cut an enormous triangle out of a sky filled with a billion stars. It descended until it was about thirty feet over the floor of the meadow. The size of the object was unbelievable. Each side of the triangle was a city block in length. I estimated its height at fifty feet or more. The size of a five story office building it sat motionless above the floor of the meadow. What followed was a horrific abduction experience. We both suffered badly from burns and dehydration and were hospitalized for two nights. I was interviewed by special agents from the USAF Security Police's "OSI" or Office of Special Investigations. They mistakenly believed I had photographed the object and I was viciously interrogated by two of their special agents. They demanded my film. My home and car were searched by consent and I was hypnotized to assist my recall. It was a nightmare that left my wife and I sour on the whole UFO and the allegations surrounding our experience. I never intended to tell anyone. But the events of 2012 opened a door to memories about the abduction experience I had long forgotten and had no desire to even remember. In 2016 and in poor health I decided it was the right time to disclose everything I knew and everything we experienced. The piece of metal in my leg was the genesis of this story. There is so much more that happened.

    Physician, researcher, and award-winning science writer, Siddhartha Mukherjee examines cancer with a cellular biologist’s precision, a historian’s perspective, and a biographer’s passion. The result is an astonishingly lucid and eloquent chronicle of a disease humans have lived with - and perished from - for more than five thousand years. The story of cancer is a story of human ingenuity, resilience, and perseverance, but also of hubris, paternalism, and misperception. Mukherjee recounts centuries of discoveries, setbacks, victories, and deaths, told through the eyes of his predecessors and peers, training their wits against an infinitely resourceful adversary that, just three decades ago, was thought to be easily vanquished in an all-out “war against cancer.” The book reads like a literary thriller with cancer as the protagonist. From the Persian Queen Atossa, whose Greek slave cut off her malignant breast, to the nineteenth-century recipients of primitive radiation and chemotherapy to Mukherjee’s own leukemia patient, Carla, The Emperor of All Maladies is about the people who have soldiered through fiercely demanding regimens in order to survive—and to increase our understanding of this iconic disease. Riveting, urgent, and surprising, The Emperor of All Maladies provides a fascinating glimpse into the future of cancer treatments. It is an illuminating book that provides hope and clarity to those seeking to demystify cancer.

    From the death of Archimedes at the hands of an irritated Roman soldier to the concoction of a superconducting witches' brew at the close of the twentieth century, the stories in Eurekas and Euphorias pour out, told with wit and relish by Walter Gratzer. Open this book at random and you may chance on the clumsy chemist named Sapper who broke a thermometer in a reaction vat and made the discovery that launched the modern dyestuff industry. Or the physicist who dissolved his gold Nobel Prize medal in acid to prevent it from falling into the hands of the Nazis. We meet mathematicians and physicists in prison cells, and even in a madhouse, making important advances in their field. And we witness the careers, sometimes tragic, sometimes carefree, of the great women scientists, from Hypatia of Alexandria, to Sophie Germain and Sonia Kovalevskaya, to Marie Curie and her relentless battle with the French Academy. A glorious parade unfolds to delight the reader, with stories to astonish, to instruct, and most especially, to entertain.

    With winds estimated at over 225 miles per hour, it was the first recorded Category 5 hurricane to make landfall in the United States.Striking at a time before storms were named, the catastrophic tropical cyclone became known as the 1935 Labor Day Hurricane, and its aftermath was felt all the way to Washington, D.C. In the hardest hit area of the Florida Keys, three out of every five residents were killed, while hundreds of World War I veterans sent there by the federal government perished.By sifting through overlooked official records and interviewing survivors and the relatives of victims, Thomas Knowles pieces together this dramatic story, moment by horrifying moment. He explains what daily life was like on the Keys, why the veteran work force was there (and relatively unprotected), the state of weather forecasting at the time, the activities of the media covering the disaster, and the actions of government agencies in the face of severe criticism over their response to the disaster.The Labor Day Hurricane of 1935 remains one of the most intense to strike America's shores. Category 5 is a sobering reminder that even with modern meteorological tools and emergency management systems, a similar storm could cause even more death and destruction today.

    At the end of the nineteenth century, serial murderer Joseph Vacher, known and feared as "The Killer of Little Shepherds," terrorized the French countryside. He eluded authorities for years--until he ran up against prosecutor Emile Fourquet and Dr. Alexandre Lacassagne, the era's most renowned criminologist. The two men--intelligent and bold--typified the Belle Epoque, a period of immense scientific achievement and fascination with science's promise to reveal the secrets of the human condition. With high drama and stunning detail, Douglas Starr revisits Vacher's infamous crime wave, interweaving the story of how Lacassagne and his colleagues were developing forensic science as we know it. We see one of the earliest uses of criminal profiling, as Fourquet painstakingly collects eyewitness accounts and constructs a map of Vacher's crimes. We follow the tense and exciting events leading to the murderer's arrest. And we witness the twists and turns of the trial, celebrated in its day. In an attempt to disprove Vacher's defense by reason of insanity, Fourquet recruits Lacassagne, who in the previous decades had revolutionized criminal science by refining the use of blood-spatter evidence, systematizing the autopsy, and doing groundbreaking research in psychology. Lacassagne's efforts lead to a gripping courtroom denouement. "The Killer of Little Shepherds" is an important contribution to the history of criminal justice, impressively researched and thrillingly told.

    His grand meteorological project had failed. Yet only a decade later, FitzRoy's storm warning system and "forecasts" would return, the model for what we use today.In an age when a storm at sea was evidence of God's wrath, nineteenth-century meteorologists had to fight against convention and religious dogma. Buoyed by the achievements of the Enlightenment, a generation of mavericks set out to decipher the secrets of the atmosphere and predict the future. Among them were Luke Howard, the first to classify clouds; Francis Beaufort, who quantified the winds; James Glaisher, who explored the upper atmosphere in a hot-air balloon; Samuel Morse, whose electric telegraph gave scientists the means by which to transmit weather warnings; and FitzRoy himself, master sailor, scientific pioneer, and founder of the U.K.'s national weather service.Reputations were built and shattered. Fractious debates raged over decades between scientists from London and Galway, Paris and New York. Explaining the atmosphere was one thing, but predicting what it was going to do seemed a step too far. In 1854, when a politician suggested to the Commons that Londoners might soon know the weather twenty-four hours in advance, the House roared with laughter.Peter Moore's The Weather Experiment navigates treacherous seas and rough winds to uncover the obsession that drove these men to great invention and greater understanding.

    Second, they all chose to die. Their spectacular deaths have become not only an integral part of their biographies, but are also inseparable from their work. A "death for ideas" is a piece of philosophical work in its own right; Socrates may have never written a line, but his death is one of the greatest philosophical best-sellers of all time.Dying for Ideas explores the limit-situation in which philosophers find themselves when the only means of persuasion they can use is their own dying bodies and the public spectacle of their death. The book tells the story of the philosopher's encounter with death as seen from several angles: the tradition of philosophy as an art of living; the body as the site of self-transcending; death as a classical philosophical topic; taming death and self-fashioning; finally, the philosophers' scapegoating and their live performance of a martyr's death, followed by apotheosis and disappearance into myth.While rooted in the history of philosophy, Dying for Ideas is an exercise in breaking disciplinary boundaries. This is a book about Socrates and Heidegger, but also about Gandhi's "fasting unto death" and self-immolation; about Girard and Passolini, and self-fashioning and the art of the essay.

    Being Mortal by Atul Gawande - A 20-minute Summary Inside this Instaread Summary: • Overview of the entire book• Introduction to the important people in the book• Summary and analysis of all the chapters in the book• Key Takeaways of the book• A Reader's Perspective Preview of this summary: Chapter 1 Gawande grew up in Ohio. His parents were immigrants from India and both were doctors. His grandparents stayed in India, and there were few older people in his neighborhood, so he had little experience with aging or death until he met his wife’s grandmother, Alice Hobson. Hobson was seventy-seven and living on her own in Virginia. She was a spirited widow who fixed her own plumbing and volunteered with Meals On Wheels. However, Hobson was losing strength and height steadily each year as her arthritis worsened.Gawande’s father enthusiastically adopted the customs of his new country, but he could not understand the way in which seniors were treated in the US. In India, the elderly were treated with great respect and lived out their lives with family.In the United States, Sitaram Gawande, Gawande’s grandfather, likely would have been sent to a nursing home like most of the elderly who cannot handle the basics of daily living by themselves. However, in India, Sitaram Gawande was able to live in his own home and manage his own affairs, with family constantly around him. He died at the age of one hundred and ten when he fell off a bus during a business trip.Until recently, most elderly people stayed with their families. Even as the nuclear family unit became predominant, replacing the multi-generational family unit, people cared for their elderly relatives. Families were large and one child, usually a daughter, would not marry in order to take care of the parents.This has changed in much of the world, where elderly people end up struggling to live alone, like Hobson, rather than living with dignity amid family, like Sitaram Gawande.One cause of this change can be found in the nature of knowledge. When few people lived to be very old, elders were honored. Their store of knowledge was greatly useful. People often portrayed themselves as older to command respect. Modern society’s emphasis on youth is a complete reversal of this attitude. Technological advances are perceived as the territory of the young, and everyone wants to be younger. High-tech job opportunities are all over the world, and young people do not hesitate to leave their parents behind to pursue them.In developed countries, parents embrace the concept of a retirement filled with leisure activities. Parents are happy to begin living for themselves once children are grown. However, this system only works for young, healthy retirees, but not for those who cannot continue to be independent. Hobson, for example, was falling frequently and suffering memory lapses. Her doctor did tests and wrote prescriptions, but did not know what to do about her deteriorating condition. Neither did her family… About the Author With Instaread Summaries, you can get the summary of a book in 30 minutes or less. We read every chapter, summarize and analyze it for your convenience.

    In The Poisoner's Handbook Blum draws from highly original research to track the fascinating, perilous days when a pair of forensic scientists began their trailblazing chemical detective work, fighting to end an era when untraceable poisons offered an easy path to the perfect crime. Drama unfolds case by case as the heroes of The Poisoner's Handbook—chief medical examiner Charles Norris and toxicologist Alexander Gettler—investigate a family mysteriously stricken bald, Barnum and Bailey's Famous Blue Man, factory workers with crumbling bones, a diner serving poisoned pies, and many others. Each case presents a deadly new puzzle and Norris and Gettler work with a creativity that rivals that of the most imaginative murderer, creating revolutionary experiments to tease out even the wiliest compounds from human tissue. Yet in the tricky game of toxins, even science can't always be trusted, as proven when one of Gettler's experiments erroneously sets free a suburban housewife later nicknamed "America's Lucretia Borgia" to continue her nefarious work. From the vantage of Norris and Gettler's laboratory in the infamous Bellevue Hospital it becomes clear that killers aren't the only toxic threat to New Yorkers. Modern life has created a kind of poison playground, and danger lurks around every corner. Automobiles choke the city streets with carbon monoxide; potent compounds, such as morphine, can be found on store shelves in products ranging from pesticides to cosmetics. Prohibition incites a chemist's war between bootleggers and government chemists while in Gotham's crowded speakeasies each round of cocktails becomes a game of Russian roulette. Norris and Gettler triumph over seemingly unbeatable odds to become the pioneers of forensic chemistry and the gatekeepers of justice during a remarkably deadly time. A beguiling concoction that is equal parts true crime, twentieth-century history, and science thriller, The Poisoner's Handbook is a page-turning account of a forgotten New York.

    These are today's sins of science—as deplorable as mistaken past ideas about advocating racial purity or using lobotomies as a cure for mental illness. These unwitting errors add up to seven lessons both cautionary and profound, narrated by renowned author and speaker Paul A. Offit. Offit uses these lessons to investigate how we can separate good science from bad, using some of today's most controversial creations—e-cigarettes, GMOs, drug treatments for ADHD—as case studies. For every "Aha!" moment that should have been an "Oh no," this book is an engrossing account of how science has been misused disastrously—and how we can learn to use its power for good.

    It killed more people in twenty-four months than AIDS killed in twenty-four years, more in a year than the Black Death killed in a century. But this was not the Middle Ages, and 1918 marked the first collision of science and epidemic disease. Magisterial in its breadth of perspective and depth of research and now revised to reflect the growing danger of the avian flu, The Great Influenza is ultimately a tale of triumph amid tragedy, which provides us with a precise and sobering model as we confront the epidemics looming on our own horizon.
