    Cruel and evil, Katherine Knight showed no mercy when she butchered her lover in a crime that put her behind bars in an Australian prison for a record life sentence.Swinging from a meat-hook, John Price's entire skin was in one piece, including his hair, face, ears, nose, mouth, and genitals. Slashes and stab holes tore through the human pelt, a testimony to the wounds he suffered before dying.Knight, a 44-year-old abattoir worker, had stabbed father-of-three John Price 37 times, skinned his body, cooked his head, and served him up as a meal for his children. Drawing on first-hand accounts, Beyond Bad tells what motivated Knight to commit such a heinous act and how it rocked the small town where she lived. This is a horrifying story of love, lust, revenge, and murder that is all the more shocking because it really happened.©2002 Sandra Lee; (P)2003 Bolinda Publishing Pty Ltd

    Foreword by Air Marshal Cliff Spink CB CBE FCMI FRAeS RAF Ret’d. After Amazon charges @£1.60 will go to the Charities When Ian Cowie, Dim Jones and Chris Long set out to produce a compendium of stories of flying in the Royal Air force – Out of the Blue – I doubt they could have anticipated what a successful venture it would be and one that has raised many thousands of pounds for service charities. Well, quite simply, they have done it again. Volume 2 contains another heady mixture of true stories that range from the amazing to the downright scary – all told with a sense of humour that was, and is, the hallmark of that band of people who have had the privilege to fly in the military arena. When I meet friends who shared the same thrills – and spills – of flying high performance aircraft close to the limits in order to get the job done, I think there is common theme to our nostalgia. And that is the “banter” – that irrepressible no holds barred, adrenaline fuelled, exchange between comrades in arms where there is no hiding from even the minor transgression. It is something we all miss but sometimes relive when reunions gather together somewhat greyer and more portly individuals than we were in days of yore. You can now share in these stories in this book which will I am sure give you a fascinating and most amusing insight into flying life in the Royal Air Force. I commend this book to you and please remember that the proceeds go to the charities that support service men and women, and their families, who have given so much for their country. Fasten your seat belts......! Amount going to charity £3.32/$5.43 (at current rate)

    So successful was he that in 1966 Rolls-Royce decided the best thing to do was to spend 63.6 million pounds and buy its rival. By this time there was scarcely a single modern British aero-engine for which Hooker had not been responsible.

    They were not the best answer, but they were the first attempts at finding a practical system. Many children that would have died, lived to have children and grandchildren. It has been calculated that over two million descendants have come from these children. The trains gave the children a fighting chance to grow up." – D. Bruce Ayler By the middle of the 19th century, New York City’s population surpassed the unfathomable number of 1 million people, despite its obvious lack of space. This was mostly due to the fact that so many immigrants heading to America naturally landed in New York Harbor, well before the federal government set up an official immigration system on Ellis Island. At first, the city itself set up its own immigration registration center in Castle Garden near the site of the original Fort Amsterdam, and naturally, many of these immigrants, who were arriving with little more than the clothes on their back, didn’t travel far and thus remained in New York. Of course, the addition of so many immigrants and others with less money put strains on the quality of life. Between 1862 and 1872, the number of tenements had risen from 12,000 to 20,000; the number of tenement residents grew from 380,000 to 600,000. One notorious tenement on the East River, Gotham Court, housed 700 people on a 20-by-200-foot lot. Another on the West Side was home, incredibly, to 3,000 residents, who made use of hundreds of privies dug into a fifteen-foot-wide inner court. Squalid, dark, crowded, and dangerous, tenement living created dreadful health and social conditions. It would take the efforts of reformers such as Jacob Riis, who documented the hellishness of tenements with shocking photographs in How the Other Half Lives, to change the way such buildings were constructed. While the Melting Pot nature of America is one of its most unique and celebrated aspects, the conditions also created a humanitarian crisis of sorts. In the 19th century, child labor was still the norm, especially for poor families, and no social welfare systems were in place to provide security for people. As a result, if a child was abandoned or orphaned, they were at the mercy of an ad hoc system of barely tolerable orphanages with little to no centralization. Minorities and immigrants were also discriminated against on the basis of ethnicity and religion. Into this issue stepped the Children’s Aid Society, led by Charles Loring Brace, who determined he could improve abandoned kids’ futures by helping relocate them further to the West, which would also help Americans settle the frontier. By coordinating with train companies, Brace was able to transport dozens of children at a time to places in the heartland of America or further out west, where they would end up in new homes, decades before the existence of foster care. Genealogist Roberta Lowrey, a descendant of one of these orphans, noted that the situations for many of those on the Orphan Trains were vastly different, but in all, the system worked: “Many were used as strictly slave farm labor, but there are stories, wonderful stories of children ending up in fine families that loved them, cherished them, [and] educated them. They were so much better off than if they had been left on the streets of New York. ... They were just not going to survive, or if they had, their fate would surely have been awful.

    In 1905 an unknown 26-year-old clerk at the Swiss Patent Office, who had supposedly failed math in school, burst on to the scientific scene and swept away the hidebound theories of the day. The clerk, Albert Einstein, introduced a new and unexpected understanding of the universe and launched the two great revolutions of twentieth-century physics, relativity and quantum mechanics. The obscure origin and wide-ranging brilliance of the work recalled Isaac Newton’s “annus mirabilis” (miracle year) of 1666, when as a 23-year-old seeking safety at his family manor from an outbreak of the plague, he invented calculus and laid the foundations for his theory of gravity. Like Newton, Einstein quickly became a scientific icon--the image of genius and, according to Time magazine, the Person of the Century.The actual story is much more interesting. Einstein himself once remarked that “science as something coming into being ... is just as subjectively, psychologically conditioned as are all other human endeavors.” In this profile, the historian of science L. Randles Lagerstrom takes you behind the myth and into the very human life of the young Einstein. From family rifts and girlfriend troubles to financial hardships and jobless anxieties, Einstein’s early years were typical of many young persons. And yet in the midst of it all, he also saw his way through to profound scientific insights. Drawing upon correspondence from Einstein, his family, and his friends, Lagerstrom brings to life the young Einstein and enables the reader to come away with a fuller and more appreciative understanding of Einstein the person and the origins of his revolutionary ideas.About the cover image: While walking to work six days a week as a patent clerk in Bern, Switzerland, Einstein would pass by the famous "Zytglogge" tower and its astronomical clocks. The daily juxtaposition was fitting, as the relative nature of time and clock synchronization would be one of his revolutionary discoveries in the miracle year of 1905.
