She's an adopted anti-heroine living as an archetype of human struggle in the 21st century, complete with a broken family, painful memories, an assailant ex-lover and a shy life that's pushed her to break out of her shell after college graduation. She was suppose to be successful. She ended up rebelling from everything normal. This is her diary based on true events. Dedicated to world peace.
"Young people need someone who is crazy about them." - Walter Brueggemann "Originally authored by Francis Clark a hundred years ago, Ashley Denton has overhauled the first writing, taking care to update and revise the text to make it more readable for a modern audience of young people. The book will be especially helpful to youth pastors, student ministry leaders and parents of young people." -Robert E. Coleman (Author of Master Plan of Evangelism) "Francis Clark believed that Jesus was the embodiment of everything that young people longed for. The challenge of every generation is simply to give young people an accurate picture of Jesus Christ. Clark believed that if young people could just see the winsome personality of Christ, they would naturally be drawn to him, like a magnet is to metal." -Ashley Denton
Ship Magnetism and the Magnetic Compass deals with the magnetism of ships and the deviation of the magnetic compass produced by this magnetism. Emphasis is placed on the distinction between the deviation itself and what causes the deviation. Numerous worked examples for exercise are found at the end of each chapter. Comprised of 15 chapters, this volume begins with an introduction to magnetometry, paying particular attention to the magnitude of the forces involved in magnetism and the manner in which these forces act. The strength of a magnetic pole is also considered, along with the angle of deflection of the needle when in two magnetic fields. Subsequent chapters offer a thorough treatment of the strength of the magnetic field and the magnet's moment of inertia and magnetic moment; the earth's magnetic force; and how the different parts of the ship's magnetic force give different types of deviation. The book also explains the heeling error and its causes; the principle underlying successful compass adjustment; the effect of the ship's magnetic forces on the directive force felt by the compass needles; and sub-permanent magnetism. This monograph will be of value to students and practitioners interested in ship magnetism and the magnetic compass.
“In his most ambitious work to date, [Edney] questions the very concept of ‘cartography’ to argue that this flawed ideal has hobbled the study of maps.” —Susan Schulten, author of A History of America in 100 Maps Over the past four decades, the volumes published in the landmark History of Cartography series have both chronicled and encouraged scholarship about maps and mapping practices across time and space. As the current director of the project that has produced these volumes, Matthew H. Edney has a unique vantage point for understanding what “cartography” has come to mean and include. In this book Edney disavows the term cartography, rejecting the notion that maps represent an undifferentiated category of objects for study. Rather than treating maps as a single, unified group, he argues, scholars need to take a processual approach that examines specific types of maps—sea charts versus thematic maps, for example—in the context of the unique circumstances of their production, circulation, and consumption. To illuminate this bold argument, Edney chronicles precisely how the ideal of cartography that has developed in the West since 1800 has gone astray. By exposing the flaws in this ideal, his book challenges everyone who studies maps and mapping practices to reexamine their approach to the topic. The study of cartography will never be the same. “[An] intellectually bracing and marvellously provocative account of how the mythical ideal of cartography developed over time and, in the process, distorted our understanding of maps.” —Times Higher Education “Cartography: The Ideal and Its History offers both a sharp critique of current practice and a call to reorient the field of map studies. A landmark contribution.” —Kären Wigen, coeditor of Time in Maps
Explores how animals are able to navigate around the world with accuracy.
The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.
After the invention of the magnetic compass and its first use in Italy for travel in the 16th century, a ship's course could be constantly monitored, leading to exploration and world trade. This intriguing guide explores a wide range of fascinating pocket compass types. Examples shown date from the late 1700s to the 1940s, with a focus on the mid-1800s and early 1900s. Hundreds of compasses are discussed with 507 colorful illustrations and detailed descriptions. The history of their development is explored, special uses for signal corps and civilian groups are presented, and patented improvements are featured. Cases for compasses include wood, leather, and brass in distinct styles around the world. The variety of craftsmanship quality, style, and value can help to identify origin and make collecting enjoyable and rewarding.
