Download or read book Halley s Quest written by Julie Wakefield and published by National Academies Press. This book was released on 2005-09-20 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most people, Edmond Halley is best known for accurately predicting the periodic appearance of the comet that ultimately would bear his name. But his greatest achievement may have been overlookedâ€" indeed few people know that it was Halley who solved the riddle of accurate navigation for all sea-going vessels. As seventeenth-century scientists gradually came to believe that the inside of the Earth was magnetized they were puzzled by the fact magnetic north not only varied slightly from place to place, but gradually changed over time, suggesting a slow variation of the Earth's magnetic field. But if the Earth was permanently magnetized, how could its magnetism vary? Edmond Halley, Britain's Astronomer Royal, ingeniously proposed that the Earth contained a number of spherical shells, one inside the other, each magnetized differently, each slowly rotating in relation to the others. This brilliant deduction earned Halley the command of a small sailing ship, the 52-foot Paramore, and with it, a royal mandate. Halley was to sail forth "to stand so far into the South, till you discover the Coast of the Terra Incognita." But more importantly, determine the variation between true and magnetic north in order to more accurately calculate longitudeâ€"a feat that would improve Britain's navigational skills and ensure its dominance of the high seas. Halley's Quest takes readers on a trilogy of sea voyages, each of which proved to be as novel and revealing as it was difficult and controversial. But more than a yarn of risk and adventure, the story at the core of the book is a deeply personal and intellectual tale that captures the science and the spirit of an almost forgotten episode in the history of navigation. Once branded a heretic by the Church and denied a prestigious scholarly chair at Oxford University, Halley ultimately changed the course of science, producing charts that described more accurate ways to navigate and documenting new geophysical phenomena ranging from ocean patterns to the motion of Jupiter's moons. This delightful book emphasizes the drama of Halley's mission and the passion of an era hungry for the stories science had to tell.

Download or read book Comets in the Post Halley Era written by R.L. Newburn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comets are always very impressive phenomena. Their appearances at regular, but mostly irregular, times excite people who see them. Astronomers have the obvious advantage of being able to see more of comets, and to study them. Their enthusiasm is reflected in the 50 papers in this book, written by more than 90 experts. The reviews in this book clearly describe a landmark in the history of cometary studies. Knowledge gathered up to and including Comet Halley are presented in two volumes. The first volume is about general aspects of observing and studying comets, where they originate and how their evolution develops. The second volume goes into the details of what a comet is: the nucleus, the coma, cometary dust, plasmas and magnetic fields. The book ends with a reflection by Fred Whipple about Comets in the Post-Halley Era. The book discusses all aspects of comets and is therefore suitable for use in graduate level courses. All astronomers and geophysicists interested in comets will find very useful and well-presented information in this book.

Download or read book Haida Quest written by Mary Razzell and published by Harbour Publishing Company. This book was released on 2002 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mike wants to head up north to the Beaufort Sea, he's got himself a good job there with an oil rig. There's no place for you, and I think you better stay in one place.... Don't look so panicky! Abandoning you? I'm not abandoning you!" With those words Lucy Haley is forced from her Chicago home into an unfamiliar world. She is placed with a grandmother she has never met in a place she has never been. Despite this alien setting, she learns over time to love both her grandmother and her new home on the Sunshine Coast of British Columbia. Talking to her grandmother and old friends of her mother's, she also comes closer to finding out the identity of her biological father. But when she attempts to contact him, she is met only with coldness; he is an internationally renowned Haida artist with a new family, and has no time for his daughter. When Lucy becomes pregnant and her grandmother becomes ill, she has no one to turn to. What follows is a story of one girl's journey from the innocence of childhood to the experience of motherhood. Along the way she is met with racism and other difficult barriers, but ultimately the love and respect taught by her Native culture brings her fractured world together.
