The Marine Chronometer: Its History and Development Marine Chronometers provides a comprehensive history of this intriguing piece of navigational equipment, tracing its evolution from the early navigational aids into the precision instrument that 5/5(2). A really superior book. It explains the problems which mariners had in establishing their longitude at sea, and how the problem was solved by John Harrison, a carpenter turned clockmaker, whom developed the first marine chronometer accurate enough at sea to allow navigators to /5(64).
"The Mariner's Chronometer" is a book about the marine chronometer like no other book, in or out of print. With many colour photographs and diagrams, it describes the structure and function of the machine, together with some of the science behind it. It then goes on to . John Harrison (– 24 March ) was a self-educated English carpenter and clockmaker who invented the marine chronometer, a long-sought-after device for solving the problem of calculating longitude while at sea.. Harrison's solution revolutionized navigation and greatly increased the safety of long-distance sea travel. The problem he solved was considered so important following the Scilly.
Rupert Thomas Gould () was not a professional horologist, yet he researched and wrote The Marine Chronometer in just four years, between the ages of 29 and A true English eccentric and a veritable polymath, Gould made important contributions in an extraordinary range of subject areas, from early typewriters to the Loch Ness Monster, from antiquarian horology to the history and. For purchasers who want an easy to read book on the practical operation and maintenance of a marine chronometer, I have found the recently published "The Mariner's Chronometer" by Bill Morris to be excellent The Mariner's Chronometer: Structure, function, maintenance and history.. It complements Rupert Gould's masterpiece/5(30).

Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time is a best-selling book by Dava Sobel about John Harrison, an 18th-century clockmaker who created the first clock (chronometer) sufficiently accurate to be used to determine longitude at sea—an important development in book was made into a television series entitled : Dava Sobel.
The workings of the device are explained in detail, along with highlights of some of the most significant makers and hints for maintenance. Topics covered include the problem of longitude, the early sea clocks, developments in France and England, the mechanism of the chronometer, and caring for chronometers/5(26).
Longitude from Dava Sobel is a fascinating account of how a virtually unknown watchmaker named John Harrison conquered one of the oldest and thorniest problems surrounding the ocean voyages - the problem of accurately measuring longitude- which stumped even the best of scientific minds for centuries.
A fascinating problem It was Ptolemy in Geographia, written in the 2nd 4/5. The book is basically the story of John Harrison and his son William who in the 18th century advanced the craft of watch and clock making, eventually producing a marine chronometer that was judged by Parliament as worthy of a major financial reward for the development of a means of measuring longitude at sea.

John Harrison arrived in London, looking for both support and the rewards promised by the Longitude Act. What was the Longitude Act. The Longitude Act was an act of parliament that offered money in return for the solution to the problem of finding a ship's precise longitude at sea.
A marine chronometer is a timepiece that is precise and accurate enough to be used as a portable time standard; it can therefore be used to determine longitude by means of accurately measuring the time of a known fixed location, for example Greenwich Mean Time (GMT) and the time at the current location.
When first developed in the 18th century, it was a major technical achievement, as accurate Classification: Clock. Problem of Longitude Finally Solved. In the device, a marine chronometer, was tested on a voyage to Lisbon.
Harrison’s clock correctly indicated the ship’s position, but he wasn’t satisfied. He went on to make more marine chronometers, each with increased accuracy.
An exact copy of his invention was even taken on Captain James. Marine chronometers are precise, specialized clocks for finding longitude at sea. They serve as portable time standards. Title: Evolution of the Marine Chronometer The development of th 1 Evolution of the Marine Chronometer.

William Whiston and Humphrey were mathematicians and friends who made a petition signed by “Captains of Her Majesty’s Ships, Merchant-Men” This piece of parchment demanded that the government pay attention to the longitude problem.
A Parliamentary committee assembled to respond. The Marine Chronometer is not only the entirely absorbing story of John Harrison's marine timekeepers, which won him the reward of GBP20, offered by the British Government for any method of finding a ship's longitude within thirty geographical miles at the end of a six weeks' voyage, but also covers the inventions of such famous scientists /5(31).
In exactly the same way as any other clock/watch does, but better. The difference is measured in better materials used, higher level of skill in putting them together and then applied skill in timing them afterwards to be within a very narrow band. Gould is the author of the book The Marine Chronometer, covering the history of chronometers from the Middle Ages through to the s.
It includes detailed descriptions of Harrison's work and the subsequent evolution of the chronometer. It remains the authoritative work on the marine chronometer. John Harrison, English horologist who invented the first practical marine chronometer, which enabled navigators to compute accurately their longitude at sea.
Harrison, the son of a carpenter and a mechanic himself, became interested in constructing an accurate chronometer in Several.The longitude problem. The measurement of longitude was a problem until well into the 18th. century. Determining latitude was relatively easy because it could be calculated from the altitude of the sun at noon but for longitude, early navigators had to rely on dead reckoning.
This was inaccurate on long voyages out of sight of land and a solution to the problem of accurately calculating.
