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: John Harrison and the Quest for Longitude, in a revised and updated edition, is a fascinating account of the life and achievements of John Harrison, the man who designed and built the first accurate marine chronometers. Inspired by the prize offered in 1714 to provide a solution to the problem of determining longitudinal position at sea, John Harrison - a carpenter by trade - set out to develop portable clocks that would rival even the most precise watches of the time. His famous 'H' timepieces went on to revolutionise sea travel and save many thousands of lives. Now housed in the collection of Royal Observatory Greenwich, they are milestones in clock- making history. Beautifully illustrated with images that showcase the intricate detail and mechanisms of the timepieces,John Harrison and the Quest for Longitudetells the story of one man driven by the need to solve one of the greatest practical problems of his time.

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: The Marine Chronometers at Greenwich is the fifth, and largest, of the distinguished series of catalogues of instruments in the collections of the National Maritime Museum. Housed at the Royal Observatory Greenwich — the 'home of time' and the Prime Meridian of the world — this extraordinary collection, which includes the celebrated marine timekeepers by John Harrison (1693-1776), is generally considered to be the finest of its kind in existence. The book is however much more than just a catalogue, and includes an accessible and engaging history of the chronometer, revealing why these instruments were important in our scientific and cultural history, and explaining, in simple terms, how they worked and were used. A comprehensive Glossary and Bibliography are included to ensure any technicalities are explained and that the reader has suggestions for useful 'further reading'. Over 480 photographs and illustrations, including many fine macro-photographs and line drawings, illustrate the 'jewel-like' beauty of the chronometer's construction and explain the function and subtleties of its mechanism. A chapter on 'How the Chronometer was Made', describes the fine sub-division of labour used to create these special machines, from bare metal, right up to delivery on board ship, and brief biographies of the makers tell the human story behind this important nineteenth-century industry. Another chapter, 'The Evolution of the Chronometer', aimed at collectors, historians and curators, provides clearly structured information on assessing and dating the chronometer, something many find difficult. And, for the dedicated specialist, there is extensive tabulated data on the technical structure of this important collection, a unique resource for future research.

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.

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.

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.
