Longitude from Dava Sobel is a fascinating account of how a virtually unknown watchmaker named John Harrison conuered 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 problemIt was Ptolemy in Geographia written in the 2nd century who contributed the concept of a co ordinate system based on the imaginary lines of latitude and longitude for accurately plotting any spot on the surface of earth With these imaginary lines he bought a new light in to the maritime explorations and map making methods of his time The sailors while at the ocean found it pretty straightforward to find their current latitude which is drawn parallel to each other while girdling the globe by measuring the height of the sun or any known celestial bodies But accurately measuring their current longitude was an entirely different case as the longitudinal lines loop from the North Pole to the South Pole and back again in great circles which converge at the ends of the earth Since it is an angular measurement which is based on time the sailors had to have access to two different times the current time on board the vessel and the time at a known and pre selected longitudinal location at the same instance for calculating the hour differences to work out the geographical separation and the longitude From a modern viewpoint with our easy to carry accurate time telling devices and instant communication this problem which a sailor faced in finding the exact time at two different locations may feel far fetched But a sailor in the middle of an ocean pre dating 18th century only had limited resources in the form of either a pendulum driven clock which was not at all reliable as the factors like gravity motion of the vessel temperature and atmospheric pressure affected the pendulum and there by the time or by comparing positions of moon or planets like Mars with their anticipatory positions in working out the longitudinal values both these methods were crude with a high level of inaccuracySince the days of Ptolemy legendary scientific and exploratory minds like Amarigo Vespucci Sir Issac Newton and Galileo Galilei did a lot of research into this matter but it took sixteen centuries for mankind to finally invent a reliable solution for this problemA tragedy the declaration of a prize moneyIn 1707 a British fleet of vessels under Admiral Sir Clowdesley Shovell met with a tragic disaster as the result of miscalculations in their whereabouts leading to the sinking of four warships with a death toll of than 1600 mariners This disaster and huge protest from the merchants and seamen resulted in the formation of a parliamentary committee for finding a practical solution for the longitude problem This was followed by the 1714 Longitude Act by the parliament which promised a prize money of 20000 for a suitable solution Dava Sobel covers this formation of the committee and the announcement of the reward in detail Sir Issac Newton who was consulted by the committee at first suggested the idea of a watch for tackling the longitude problem One method is by a Watch to keep time exactly But by reason of the motion of the Ship the Variation of Heat and Cold Wet and Dry and the Difference of Gravity in different Latitudes such a watch hath not yet been made But he believed that such a watch with too many technical challenges was not going to be a reality and was aligned towards finding a solution for the longitude problem in the realms of astronomy A good watch may serve to keep a reckoning at Sea for some days and to know the time of a celestial Observation and for this end a good Jewel watch may suffice till a better sort of Watch can be found out But when the Longitude at sea is once lost it cannot be found again by any watch Newton died in 1727 and therefore did not live to see the predecessor of the modern day chronometers become a reality At the same time another less known figure a skilled watchmaker from Lincolnshire named John Harrison who was stimulated by the scientific and the monetary factors surrounding this riddle decided to find a solution of his own Possessed with a brilliant mind he succeeded initially in creating a prototype and then further versions of perfect working models of the world s first marine chronometers thereby revolutionizing the ocean travels His handmade sea clocks which are elaborate pieces of engineering marvels and still in display in working condition at the Royal Observatory Greenwich England gave the world the first reliable method for measuring the longitude Dava Sobel records the background and each step of this pioneering invention in an easy to read form by guiding the reader through a tumultuous story of the sheer determination and relentless pursuit for perfection from a self made man and the obstructions unkempt promises and villainy he had to face from some of his jealous contemporaries This concise and engaging chronicle of an innovative engineering deed covers a lot of details on the history science and politics which led to this invention and is a recommended read for anyone who is interested in maritime history and science Since I read an updated fully illustrated edition of Longitude which was published later the book was a treasure trove with a large selection of rare photographs including Harrison s sea clocks documents of declarations letters scientific articles maps and diagrams which added greatly to the value of the volume The illustrated edition is highly recommended American Lion Andrew Jackson in the White House in the eighteenth century would have known that the longitude problem was the thorniest

This book was intended for the general reader Conseuently it did not deal much with the details either of the astronomical or mechanical approaches to solving the problem of finding longitude on the high seas Instead it focused on description of John Harrison s uest to build an ocean chronometer The author treats the difficulties Harrison encountered convincing the Board of Longitude of the efficacy of his devices as a matter of petty politics and egotism without offering the reader sufficient detail about the technical disputes to make any judgments about the scientific debate at the center of the controversyThis book was a bit of a disappointment considering the glowing reviews it received

Longitude is a remarkable achievement The recipe for sales success in international book sales rarely contains such unpromising ingredients as these an obsessive carpenter s son from Yorkshire an intractable navigational problem and a lot of clocks Yet Longitude succeeds in weaving a narrative full of clashing of ideas intriguing personalities bizarre anecdotes and at its heart a tale of the little guy challenging the EstablishmentThe story is one that has long been familiar to both naval historians and lovers of clocks two introspective groups who had failed to bring it to a wider public Enter Dava Sorbel with a journalist s nose for a good story and the flare to tell it well This is a page turner that makes what could be a mire of mechanical and mathematical detail simple easy to follow and enjoy by anyone whether they are confirmed landlubbers or have a previous interest in the seaFrom a purest point of view the book does have its faults Sorbel s understandable desire to tease a cracking yarn from the history leads her to be partial in choosing her facts She is unfairly hard on the HalleyMaskylene method of calculating longitude for example which worked too and had the big advantage of only reuiring euipment that already exist onboard ships a good compass a sextant and a trained navigator It is small wonder that an unproven machine full of cogs and springs was viewed with suspicion It is also only with hindsight that it is clear the marine chronometers was the right solution The copy of H4 that Cook used on his second voyage cost 450 and took a skilled watch maker several years to make To give an indication of cost building a frigate at the time cost about 14K Given each ship would need several chronometers to check against each other at the time of Harrison s death it was still not a practical solution for most vessels It was those that came after Harrison especially Thomas Earnshaw who perfected and then mass produced reliable chronometersBut that is the grumpy naval historian part of me speaking The author of popular naval fiction part can only applaud a wonderful book
