Ships Clocks And Stars

Richard Dunn Harper Collins

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.

Navigational Instruments

Richard Dunn Bloomsbury Publishing

With over two-thirds of the globe covered by water, the ability to navigate safely and quickly across the oceans has been crucial throughout human history. As seafarers attempted longer and longer voyages from the sixteenth century onwards in search of profit and new lands, the tools of navigation became ever more sophisticated. The development of instruments over the last five hundred years has seen some revolutionary changes, spurred on by the threat of disaster at sea and the possibility of huge rewards from successful voyages. As this book shows, the solution of the infamous longitude problem, the extraordinary impact of satellite positioning and other advances in navigation have successfully brought together seafarers, artisans and scientists in search of better ways of getting from A to B and back again.

Time And Navigation

Andrew Kenneth Johnston

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.

Finding Longitude

Richard Dunn

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.
