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.

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: 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.

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.

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.

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.

Book excerpt: The pendulum is a constant source of interest to scientists. Great and well-known inventors such as Galileo, Huygens, and Kelvin all devised mechanisms to maintain its even oscillations. Others such as John Harrison, Lord Grimthorpe, and William Shortt are known only in horological circles but contributed as much or more over three centuries. By writing a personal account of his own inventions and achievements in horology the author involves the reader in the history of precision time-keeping before the advent of atomic clocks and the quartz chip. Escapements, the mechanisms that drive pendulums, are a delight to the geometrical mind as well as a delicate and subtle challenge to the mechanical engineer. In their most refined form pendulum clocks not only keep astonishingly accurate time they are also sensitive enough to detect the ebb and flow of tides and even the ceaseless quivering of the Earth itself. Philip Woodward's deep knowledge of and passion for time-keeping mechanisms is evident throughout this highly readable and fascinating account of precision horology.

Book excerpt: One of Smithsonian Magazine's Ten Best History Books of 2021 A captivating, surprising history of timekeeping and how it has shaped our world. For thousands of years, people of all cultures have made and used clocks, from the city sundials of ancient Rome to the medieval water clocks of imperial China, hourglasses fomenting revolution in the Middle Ages, the Stock Exchange clock of Amsterdam in 1611, Enlightenment observatories in India, and the high-precision clocks circling the Earth on a fleet of GPS satellites that have been launched since 1978. Clocks have helped us navigate the world and build empires, and have even taken us to the brink of destruction. Elites have used them to wield power, make money, govern citizens, and control lives—and sometimes the people have used them to fight back. Through the stories of twelve clocks, About Time brings pivotal moments from the past vividly to life. Historian and lifelong clock enthusiast David Rooney takes us from the unveiling of al-Jazari’s castle clock in 1206, in present-day Turkey; to the Cape of Good Hope observatory at the southern tip of Africa, where nineteenth-century British government astronomers moved the gears of empire with a time ball and a gun; to the burial of a plutonium clock now sealed beneath a public park in Osaka, where it will keep time for 5,000 years. Rooney shows, through these artifacts, how time has been imagined, politicized, and weaponized over the centuries—and how it might bring peace. Ultimately, he writes, the technical history of horology is only the start of the story. A history of clocks is a history of civilization.

Available in PDF, EPUB and Kindle. Book excerpt: LOST AT SEA: EVERY MARINER'S FEAR. Maritime navigational tools could find latitude, but finding longitude remained elusive until Harrison developed the reliable sea clock, H4. Building on H4's success, Kendall made a series of nautical timekeepers, K1, K2 and K3. This is the story of the K2 timekeeper; its adventurous voyages, the people it touched, and its place in history. K2's first voyage, accompanied by the young Nelson, was nearly its last in the crushing Arctic ice. The next two expeditions saw it survive kidnappings, nautical intrigue, and gunpowder plots of the American revolutionary wars. The slave coasts of Africa followed. Bligh took K2 on the Bounty, but lost it in a fight with the mutineers in 1789. It was recovered by an American Quaker from Nantucket, only to be stolen by the Spanish. It rode on mules along the Andes before sailing into the Opium Wars. K2 finally returned to Greenwich in 1963. DRAMATIC, THREE NATION 'STORY OF TIME'
