The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it.  The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.Levitt’s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

    In the style of his first book, Andy recalls each event from the detailed documentation recorded at the time, each account written in a way that puts the reader right there next to him so that you live the events in real-time, hear the dialogue between paramedics, patient, their loved ones and other healthcare professionals as it would have been, and share in Andy’s thought processes during each of the ten very different situations he encounters.The term ‘The Dark Side’ describes the frontline emergency aspect of the Ambulance Service, since paramedics frequently experience sombre situations. In ‘The Dark Side, Part 2’ you will share in some truly traumatic, tragic and tearful events involving a seemingly vibrant, healthy young patient, a prison inmate, the victims of an horrific car crash, heart attacks, a frightening epileptic fit, the alarming effects of an allergic reaction, and what can happen when under-strain doctors prescribe the wrong medication. But there’s still room for lighthearted moments and a taste of the sometimes dark humour that allows paramedics to continually deal with events most of us would find too horrific. The detail in the descriptions of the care given to each patient on-scene by Andy and his colleagues will have you marvelling at the ability of these healthcare professionals to work at such speed of thought, buying enough time to deliver a patient into the specialist hands of hospital care and often full recovery. Of course there are inevitably also those times when tears of hope turn to tears of despair for loved ones. You cannot feel that pain until it happens to you, but this book will bring you mighty close to it at times.

    Guns are drawn, and in the ensuing hail of bullets, only the husband walks away. However, police soon find out, that what seems to be a robbery gone wrong is anything but. The Case of the Ragged Stranger, as the tabloids dubbed it, is a tale of deceit, betrayal, and depravity, a stranger-than-fiction mystery story whose shocking solution riveted the nation and made it one of the most sensational crimes of the Jazz Age.

    Full of striking, singular art, this collection also contains infographics about relevant topics such as lab equipment, rates of women currently working in STEM fields, and an illustrated scientific glossary. The women profiled include well-known figures like primatologist Jane Goodall, as well as lesser-known pioneers such as Katherine Johnson, the African-American physicist and mathematician who calculated the trajectory of the 1969 Apollo 11 mission to the moon.

    This new celebration of these letters is illustrated with portraits, facsimile letters, topographical engravings and fashion plates, and aims to bring to life the world Jane Austen inhabited. Although the book follows a broadly chronological scheme, the letters are arranged round visual themes considered particularly suitable for illustration, such as the Hampshire countryside, social life in Bath and London, domestic pursuits, paying visits and travelling by carriage. The author, who was born in Jane Austen's Hampshire village, lectures on English Literature for the Open University and the Oxford University Department of External Studies. Her special interest is 19th-century children's literature and she has compiled an anthology, "Childhood".

    In the tradition of unsolved historical mysteries like David Grann's Killers of the Flower Moon and Douglas Preston's The Lost City of the Monkey God, Brian Muraresku’s 10-year investigation takes the reader through Greece, Germany, Spain, France and Italy, offering unprecedented access to the hidden archives of the Louvre and the Vatican along the way.In The Immortality Key, Muraresku explores a little-known connection between the best-kept secret in Ancient Greece and Christianity. This is the real story of the most famous human being who ever lived (Jesus) and the biggest religion the world has ever known. Today, 2.4 billion people are Christian. That's one third of the planet. But do any of them really know how it all started?Before Jerusalem, before Rome, before Mecca—there was Eleusis: the spiritual capital of the ancient world. It promised immortality to Plato and the rest of Athens's greatest minds with a very simple formula: drink this potion, see God. Shrouded in secrecy for millennia, the Ancient Greek sacrament was buried when the newly Christianized Roman Empire obliterated Eleusis in the fourth century AD.Renegade scholars in the 1970s claimed the Greek potion was psychedelic, just like the original Christian Eucharist that replaced it. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The rapidly growing field of archaeological chemistry has proven the ancient use of visionary drugs. And with a single dose of psilocybin, the psycho-pharmacologists at Johns Hopkins and NYU are now turning self-proclaimed atheists into instant believers. No one has ever found hard, scientific evidence of drugs connected to Eleusis, let alone early Christianity. Until now.Armed with key documents never before translated into English, convincing analysis, and a captivating spirit of quest, Muraresku mines science, classical literature, biblical scholarship and art to deliver the hidden key to eternal life, bringing us to what clinical psychologist William Richards calls "the edge of an awesomely vast frontier."Featuring a Foreword by Graham Hancock, the New York Times bestselling author of America Before: The Key to Earth's Lost Civilization.

    ‘Help for the helpless in the storms of the Sierra Nevada Mountains!’" – Eliza P. Donner Houghton, The Expedition of the Donner Party and Its Tragic Fate The westward movement of Americans in the 19th century was one of the largest and most consequential migrations in history, and for countless people back east, the West represented opportunities for adventure, independence, and fortune. Even in the 21st century, Americans look back on the era fondly, even romantically, and millions are familiar with the popular game that reignited interest in the Oregon Trail Of course, it’s easy for people with modern transportation to comfortably reminisce about the West, because many pioneers discovered that the traveling was fraught with various kinds of obstacles and danger, including bitter weather, potentially deadly illnesses, and hostile Native Americans, not to mention an unforgiving landscape that famous American explorer Stephen Long deemed “unfit for human habitation.” 19th century Americans were all too happy and eager for the transcontinental railroad to help speed their passage west and render overland paths obsolete. One of the main reasons people yearned for new forms of transportation is because of the most notorious and tragic disasters in the history of westward travel. While people still romanticize the Wild West, many Americans are still all too familiar with the fate of the Donner Party, a group of 87-90 people that met with disaster in the Sierra Nevada mountain range during the winter of 1846-1847. The party knew the journey would take months, but early snowfalls in the mountains left dozens of people trapped in snow drifts that measured several feet, stranding them in a manner that made it virtually impossible for them to go any further for several weeks. Inevitably, as the Donner Party’s supplies began to run low, there was little hope of acquiring new provisions high up in the mountains, and even worse, their location and the technology of the time also made it virtually impossible for relief expeditions to reach them. Due to exposure and lack of food, the health of many in the party began to deteriorate quickly in the tough winter conditions, and the animals brought along with the group died at alarming rates. Most of the men who set out to try to get help died en route, while the families back in camp tried to cope with dozens of deaths suffered by young and old alike. As a few able-bodied people went for help, the people who remained back in their wagons resorted to the most desperate of measures in attempts to either stay alive or keep their children alive. Some members of the Donner Party fought with each other, occasionally fatally, and the journey is perhaps best known today for accounts of cannibalism. One member of the group noted in his diary in February 1847, "Mrs Murphy said here yesterday that thought she would Commence on Milt. & eat him. I dont that she has done so yet, it is distressing.” All the while, the plight of the Donner Party made news across the nation, even before the surviving members were rescued and brought to safety, and by the time the doomed expedition was over, less than 50 of them made it to California.

    A basic idea that proved elusive for hundreds of years and bent the minds of the greatest thinkers in the world, the algorithm is what made the modern world possible. Without the algorithm, there would have been no computer, no Internet, no virtual reality, no e-mail, or any other technological advance that we rely on every day.In The Advent of the Algorithm, David Berlinski combines science, history, and math to explain and explore the intriguing story of how the algorithm was finally discovered by a succession of mathematicians and logicians, and how this paved the way for the digital age. Beginning with Leibniz and culminating in the middle of the twentieth century with the groundbreaking work of Gödel and Turing, The Advent of the Algorithm is an epic tale told with clarity and imaginative brilliance.

    There, it's said " Maps not only show the world, they help it turn. On an average day, we will consult some form of map approximately a dozen times, often without even noticing: checking the A-Z, the road atlas, or the Sat Nav, scanning the tube or bus map, a quick Google online, or hours wasted flying over a virtual Earth, navigating a way around a shopping center, watching the weather forecast, planning a walk or a trip, catching up on the news, booking a holiday or hotel. Maps pepper logos, advertisements, illustrations, books, web pages, and newspaper and magazine articles: they are a cipher for every area of human existence. At a stroke, they convey precise information about topography, layout, history, politics, and power. They are the unsung heroes of life, and this guide sings their song. There are some fine, dry tomes out there about the history and development of cartography: this is not one of them. This exploration mixes wry observation with hard fact and considerable research, unearthing the offbeat, the unusual, and the downright pedantic in a celebration of all things maps. In "Map Addict," we learn the location of what has officially been named by the OS as the most boring square kilometer in the land; we visit the town fractured into dozens of little parcels of land split between two different countries and trek around many other weird borders of Britain and Europe; we test the theories that the new city of Milton Keynes was built to a pagan alignment and that women can't read maps. Combining history, travel, politics, memoir, and oblique observation in a highly readable, and often very funny, style, Mike Parker confesses how his own impressive map collection was founded on a virulent teenage shoplifting habit, ponders how a good leftie can be so gung-ho about British cartographic imperialism, and wages a one-man war against the moronic blandishments of the Sat Nav age.

    A small six inches by nine inches, but over two hundred pages long, with odd illustrations of plants, astrological diagrams, and naked women, it is written in so indecipherable a language and contains so complicated a code that mathematicians, book collectors, linguists, and historians alike have yet to solve the mysteries contained within.However, in The Friar and the Cipher, the acclaimed bibliophiles and historians Lawrence and Nancy Goldstone describe, in fascinating detail, the theory that Roger Bacon, the noted thirteenth-century, pre-Copernican astronomer, was its author and that the perplexing alphabet was written in his hand. Along the way, they explain the many proposed solutions that scholars have put forth and the myriad attempts at labeling the manuscript’s content, from Latin or Greek shorthand to Arabic numerals to ancient Ukrainian to a recipe for the elixir of life to good old-fashioned gibberish.As we journey across centuries, languages, and countries, we meet a cast of impassioned characters and case-crackers, including, of course, Bacon, whose own personal scientific contributions, Voynich author or not, were literally and figuratively astronomical.

    But what do we mean by 'the bush', and how has it shaped us? Starting with his forebears' battle to drive back nature and eke a living from the land, Don Watson explores the bush as it was and as it now is: the triumphs and the ruination, the commonplace and the bizarre, the stories we like to tell about ourselves and the national character, and those we don't. Via mountain ash and mallee, the birds and the beasts, slaughter, fire, flood and drought, swagmen, sheep and their shepherds, the strange and the familiar, the tragedies and the follies, the crimes and the myths and the hope – here is a journey that only our leading writer of non-fiction could take us on. At once magisterial in scope and alive with telling, wry detail, The Bush lets us see our landscape and its inhabitants afresh, examining what we have made, what we have destroyed, and what we have become in the process. No one who reads it will look at this country the same way again.
