A book review of longitude the true story of a lone genius who solved the greatest scientific proble

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. 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.

Some of the tests are designed to be more difficult than others. 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.

It was charged with, among a range of scientific activities, the improvement of maps and sailing charts and advancement of the science of navigation.

BKMT READING GUIDES

This lush, colorfully illustrated edition adds lots of pictures to the story, giving readers a more satisfying sense of the times, the players, and the puzzle. Hand the abstracts out in class as a study guide, or use them as a "key" for a class discussion.

Pass the forms out before you assign reading, so students will know what to expect. On the deck of a rolling ship such clocks would slow down, or speed up, or stop running altogether.

Once you download the file, it is yours to keep and print for your classroom. It is difficult to realize that a problem that can now be solved with a couple of cheap watches and a few simple calculations at one time appeared insurmountable.

The major theme of the book is the extraordinary and surprising sources of excellence. They ask students to demonstrate a deeper understanding of Longitude: This was no obscure, curious difficulty--without longitude, ships often found themselves so far off course that sailors would starve or die of scurvy before they could reach port.

Because her work provides awareness of science and technology to the general public, she has received the Individual Public Service Award from the National Science Board inthe Bradford Washburn Award in ,the Klumpke-Roberts Award inand the Eduard Rhein Foundation in Germany in Use the entire Longitude: Whatever could be discovered from solving the problem at sea would only improve the determination of longitude on land.

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.

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 inaccuracy.

Gale Group is a Thomson Corporation Company. Longitude is the story of English clockmaker John Harrison and how he figured out how to track longitude, or the east-west position of ships. But when the Longitude at sea is once lost, it cannot be found again by any watch.

Typically, there are questions per chapter, act or section. Retrieved Sep 27 from https: The scientific establishment of Europefrom Galileo to Sir Isaac Newtonhad mapped the heavens in both hemispheres in its certain pursuit of a celestial answer.

Longitude is well-timed too, as the new Umberto Eco novel The Island of the Day Before features a protagonist marooned on an 18th-century vessel stocked with bizarre longitude instruments. Finally, Parliament bestowed a cash prize and deed of thanks on Harrison directly, so at least the inventor died with the knowledge of his vindication.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 navigation.

Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time won the Harold D. Vursell Memorial Award from the American Academy of Arts and Letters.

Galileo's Daughter: A Historical Memoir of Science, Faith, and Love won the Los Angeles Times Book Prize for science and technology and a /5(73). 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/5().
