Dava Sobel, like Simon Winchester or Canada's Pierre Berton, has clearly mastered the art of writing history in a form that is not only informative but, perhaps more important, is also compelling and entertaining. of the world for the better part of human history.'' In fact, so frustrating was this problem that it came to be thought of as synonymous with impossibility.

But the real difference, as the she notes, is that the zero-degree parallel of latitude is fixed by nature and is the equator, while the zero-degree meridian of longitude is simply wherever science decides to place it (for more thanBefore Britannia could rule the waves, its captains needed to figure out where their ships were going and, just as importantly, how to return home.

Despite it's brevity, Longitude is an incredibly engaging and educational book. Sobel writes in a way that makes the science and math accessible to the general reader. The inability to solve the longitude problem for so long also had dire consequences. If a ship didn't know how far to the east or west it had traveled, then it didn't know where land was likely to be, and the unexpected contiguity of land had A play based on Galileo's Daughter, written by Timberlake Wertenbaker and directed by Sir Peter Hall, premiered in Bath, England, in July 2004.

You might think that Harrison's incredible devices would be unanimously welcomed. Alas, no. He was forever battling vested interests until eventually, and after decades, King George III intervened.

Her book Galileo's Daughter: A Historical Memoir of Science, Faith, and Love was a finalist for the 2000 Pulitzer Prize for Biography or Autobiography. [2] Dava Sobel in November 2007 Navigating purely by latitude was of course vulnerable if the sun was clouded over at noon, and caused problems as it prevented ships from taking the most direct route, a great circle, or a route with the most favourable winds and currents, extending voyages by days or even weeks. This increased the likelihood of short rations, [3] scurvy or starvation leading to poor health or even death for members of the crew and resultant risk to the ship. The Discovery of the Longitude is of such Consequence to Great Britain for the safety of the Navy and Merchant Ships as well as for the improvement of Trade that for want thereof many Ships have been retarded in their voyages, and many lost..." and announced the Longitude Prize "for such person or persons as shall discover the Longitude." It 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.

Success!

The prizes were to be awarded to the first person to demonstrate a practical method for determining the longitude of a ship at sea. Each prize, in increasing amounts, was for solutions of increasing accuracy. These prizes, worth millions of dollars in today's currency, motivated many to search for a solution.
