Book excerpt: The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

Book excerpt: If you want to know where you are, you need a good clock. The surprising connection between time and placeais explored inaTime and Navigation- The Untold Story of Getting from Here to There, the companion book to the National Air and Space Museum exhibition of the same name. Today we use smartphones and GPS, but navigating has not always been so easy. The oldest "clock" is Earth itself, and the oldest means of keeping time came from observing changes in the sky. Early mariners like the Vikings accomplished amazing feats of navigation without using clocks at all. Pioneering seafarers in the Age of Exploration used dead reckoning and celestial navigation; later innovations such as sextants and marine chronometers honed these techniques by measuring latitude and longitude. When explorers turned their sights to the skies, they built on what had been learned at sea. For example, Charles Lindbergh used a bubble sextant on his record-breaking flights. World War II led to the development of new flight technologies, notably radio navigation, since celestial navigation was not suited for all-weather military operations. These forms of navigation were extended and enhanced when explorers began guiding spacecraft into space and across the solar system. Astronauts combined celestial navigation technology with radio transmissions. The development of the atomic clock revolutionized space flight because it could measure billionths of a second, thereby allowing mission teams to navigate more accurately. Scientists and engineers applied these technologies to navigation on earth to develop space-based time and navigation services such as GPS that is used every day by people from all walks of life. While the history of navigation is one of constant change and innovation, it is also one of remarkable continuity. Time and Navigation tells the story of navigation to help us understand where we have been and how we got there so that we can understand where we are going.

Download or read book Harrison Decoded written by Rory McEvoy and published by Oxford University Press. This book was released on 2020-04-27 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harrison Decoded: Towards a Perfect Pendulum Clock brings together the output of a forty-year collaborative research project that unpicked and put into practice the fine details of John Harrison's extraordinary pendulum clock system. Harrison predicted that his unique method of making pendulum clocks could provide as much as one-hundred-times the stability of those made by his contemporaries. However, his final publication, which promised to describe the system, was a chaotic jumble of information, much of which had nothing to do with clockwork. One contemporary reviewer of Harrison's book could only suggest that the end result was a product of Harrison's 'superannuated dotage.' The focus of this book centres on the making, adjusting, and testing of Clock B which was the subject of various trials at the Royal Observatory, Greenwich. The modern history of Clock B is accompanied by scientific analysis of the clock system, Clock B's performance, the methods of data-gathering alongside historical perspectives on Harrison's clockmaking, that of his contemporaries, and some evaluation of the possible influence of early 18th century scientific thought.
Download or read book Time Restored written by Jonathan Betts and published by OUP Oxford. This book was released on 2011-05-19 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of Rupert T. Gould (1890-1948), the polymath and horologist. A remarkable man, Lt Cmdr Gould made important contributions in an extraordinary range of subject areas throughout his relatively short and dramatically troubled life. From antique clocks to scientific mysteries, from typewriters to the first systematic study of the Loch Ness Monster, Gould studied and published on them all. With the title The Stargazer, Gould was an early broadcaster on the BBC's Children's Hour when, with his encyclopaedic knowledge, he became known as The Man Who Knew Everything. Not surprisingly, he was also part of that elite group on BBC radio who formed The Brains Trust, giving on-the-spot answers to all manner of wide ranging and difficult questions. With his wide learning and photographic memory, Gould awed a national audience, becoming one of the era's radio celebrities. During the 1920s Gould restored the complex and highly significant marine timekeepers constructed by John Harrison (1693-1776), and wrote the unsurpassed classic, The Marine Chronometer, its History and Development. Today he is virtually unknown, his horological contributions scarcely mentioned in Dava Sobel's bestseller Longitude. The TV version of Longitude, in which Jeremy Irons played Rupert Gould, did at least introduce Gould's name to a wider public. Gould suffered terrible bouts of depression, resulting in a number of nervous breakdowns. These, coupled with his obsessive and pedantic nature, led to a scandalously-reported separation from his wife and cost him his family, his home, his job, and his closest friends. In this first-ever biography of Rupert Gould, Jonathan Betts, the Royal Observatory Greenwich's Senior Horologist, has given us a compelling account of a talented but flawed individual. Using hitherto unknown personal journals, the family's extensive collection of photographs, and the polymath's surviving records and notes, Betts tells the story of how Gould's early life, his naval career, and his celebrity status came together as this talented Englishman restored part of Britain's - and the world's - most important technical heritage: John Harrison's marine timekeepers.

Available in PDF, EPUB and Kindle. Book excerpt: A tale of eighteenth-century invention and competition, commerce and conflict, this is a lively, illustrated, and accurate chronicle of the search to solve “the longitude problem,” the question of how to determine a ship’s position at sea—and one that changed the history of mankind. Ships, Clocks, and Stars brings into focus one of our greatest scientific stories: the search to accurately measure a ship’s position at sea. The incredible, illustrated volume reveals why longitude mattered to seafaring nations, illuminates the various solutions that were proposed and tested, and explores the invention that revolutionized human history and the man behind it, John Harrison. Here, too, are the voyages of Captain Cook that put these revolutionary navigational methods to the test. Filled with astronomers, inventors, politicians, seamen, and satirists, Ships, Clocks, and Stars explores the scientific, political, and commercial battles of the age, as well as the sailors, ships, and voyages that made it legend—from Matthew Flinders and George Vancouver to the voyages of the Bounty and the Beagle. Featuring more than 150 photographs specially commissioned from Britain’s National Maritime Museum, this evocative, detailed, and thoroughly fascinating history brings this age of exploration and enlightenment vividly to life.

This book was released on 2007-10-17 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A brilliant and readable book…a rich study of humankind's restless spirit." —Candice Millard, New York Times Book Review Greeted with coast-to-coast acclaim on publication, Fernández-Armesto's ambitious history of world exploration sets a new standard. Presenting the subject for the first time on a truly global scale, Fernández-Armesto tracks the pathfinders who, over the past five millennia, lay down the routes of contact that have drawn together the farthest reaches of the world. The Wall Street Journal calls it "impressive...a huge story [told] with gusto and panache." To the Washington Post, "Pathfinders is propelled by an Argonaut of an author, indefatigable and daring. It's a wild ride." And in a front-page review, the Seattle Times hails its "tart and elegant presentation...full of surprises. Fernández-Armesto's lively mind, pithy phrasing, and stunningly thorough and diverse knowledge are a constant pleasure." A plenitude of illustrations and maps in color and black and white augment this rich history. In Pathfinders, winner of the 2007 World History Association Book Prize, we have a definitive treatment of a grand subject.

Available in PDF, EPUB and Kindle. Book excerpt: In the past three centuries the ship has developed from the relatively unsophisticated sail-driven vessel which would have been familiar to the sailors of the Tudor navy, to the huge motor-driven container ships, nuclear submarines and vast cruise liners that ply our seas today. Who were the innovators and builders who, during that span of time, prompted and instigated the most significant advances? In the past three centuries the ship has developed from the relatively unsophisticated sail-driven vessel which would have been familiar to the sailors of the Tudor navy, to the huge motor-driven container ships, nuclear submarines and vast cruise liners that ply our seas today. Who were the innovators and builders who, during that span of time, prompted and instigated the most significant advances? In this new book the author describes the lives and deeds of more the 120 great engineers, scientists, philosophers, businessmen, shipwrights, naval architects and inventors who shaped ship design and shipbuilding world wide. Covering the story chronologically, and going back briefly even to Archimedes, such well-known names as Anthony Deane, Peter the Great, James Watt, Robert Fulton and Isambard Kingdom Brunel share space with lesser known characters like the luckless Frederic Sauvage, a pioneer of screw propulsion who, unable to interest the French navy in his tests in the early 1830s, was bankrupted and landed in debtors prison. With the inclusion of such names as Ben Lexcen, the Australian yacht designer who developed the controversial winged keel for the 1983 Americas Cup, the story is brought right up to date. Concise linking chapters place all these innovators in context so that a clear and fascinating history of the development of ships and shipbuilding emerges from the pages. An original and important new reference book.

Available in PDF, EPUB and Kindle. Book excerpt: Hapgood utilizes ancient maps as concrete evidence of an advanced worldwide civilization existing many thousands of years before ancient Egypt. Hapgood concluded that these ancient mapmakers were in some ways much more advanced in mapmaking than any people prior to the 18th century. Hapgood believes that they mapped all the continents. This would mean that the Americas were mapped thousands of years before Columbus. Antarctica would have been mapped when its coasts were free of ice. Hapgood supposes that there is evidence that these people must have lived when the Ice Age had not yet ended in the Northern Hemisphere and when Alaska was still connected with Siberia by the Pleistocene, Ice Age 'land bridge'.
Download or read book Finding Longitude written by Richard Dunn and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Official publication of the National Maritime Museum's exhibition "Ships, Clocks and Stars: The Quest for Longitude". 300 years ago, amidst growing frustration from the naval community and pressure from the increasing importance of international trade, the British government passed the 1714 Longitude Act. It was an attempt to solve one of the most pressing problems of the age: how to determine a ship's longitude (east-west position) at sea. With life-changing rewards on offer, the challenge captured the imaginations and talents of astronomers, skilled craftsmen, politicians, seamen and satirists. This beautifully illustrated book is a detailed account of these stories, and how the longitude problem was solved. Highlights of the book include: * Foreword by the fifteenth Astronomer Royal, Martin Rees. * Specially commissioned photographs of the National Maritime Museum's collection. * A new description of the collaborations and conflicts in a tale of technical creativity, scientific innovation and hard commercialism. From the same publisher as Dava Sobel's Longitude, Finding Longitude tells a new story of one of the great achievements of the Georgian age, and how it changed our understanding of the world.
Download or read book Chronometer Makers of the World written by Tony Mercer and published by Robert Hale. This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, Tony Mercer, grandson of the most enduring English maker, has studied and collected a huge amount of information about marine chronometers, instruments which enabled explorers and the Royal Navy to map the world, the Navy to police it, and merchant venturers to sail in relative safety. The purpose of the chronometer is reviewed largely as a navigational aid for ocean-going vessels, but also for survey, medical, and other activities calling for precise time measurement. Representative examples of chronometers and deck watches by international makers--from the earliest known to contemporary instruments--are illustrated in both color and black and white. A comprehensive list of makers and craftsmen brings together details of men who worked in the industry, their places of work, and dates and serial numbers for their instruments.
