Chapter 5 Longitude Meaning & Theme

1. Meaning for Longitude 

"Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time" is a book written by Dava Sobel. It tells the real-life story of John Harrison, an English clockmaker who dedicated his life to solving the problem of determining longitude at sea during the 18th century.

During that time, sailors faced immense challenges in navigating the open seas because they couldn't accurately determine their east-west position. Latitude, which measures distance north or south of the Equator, could be determined relatively easily using celestial observations. However, longitude, which measures distance east or west of a reference point, proved to be much more elusive.

Harrison's incredible journey is chronicled in this book, which highlights his determination and ingenuity in developing a highly accurate marine chronometer. This instrument, known as H4, revolutionized navigation by enabling sailors to measure the time accurately while at sea. By comparing the local time with the time at a reference point, usually Greenwich, London, sailors could calculate their longitude.

The book explores how the solution to this scientific problem was not only a technological achievement but also a triumph over societal and political barriers. It delves into the various struggles faced by Harrison, such as the resistance from established experts and institutions who favored astronomical methods for determining longitude.

Through "Longitude," the author sheds light on the significance of Harrison's work and its impact on maritime history. It showcases the perseverance of a lone genius who solved one of the greatest scientific challenges of his time, forever changing the way navigation was conducted at sea.
