Sea voyages plagued from "summary" of Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time by Dava Sobel
Sea voyages plagued by the mysterious and deadly problem of determining longitude, the east-west position at sea, faced immense challenges and risks. Without an accurate method to calculate longitude, sailors were often left to rely on dead reckoning, a crude technique based on estimating distance traveled from a known point. This method was highly unreliable, leading to countless ships running aground or becoming lost at sea. The consequences of these navigational errors were dire, resulting in the loss of countless lives and valuable cargo. The lack of a reliable solution to the problem of longitude plagued maritime nations for centuries, hindering exploration, trade, and naval warfare. The quest for a practical and accurate method to determine longitude became a pressing concern for governments, scientists, and navigators alike. Despite numerous attempts to solve this problem, including rewards offered by governments and scientific societies, progress was slow and elusive. In the face of this seemingly insurmountable challenge, a lone genius emerged: John Harrison, a self-taught clockmaker with a keen interest in solving the problem of longitude. Harrison dedicated his life to designing and building precision timepieces known as chronometers, which could accurately keep time at sea. By using these chronometers to measure the time difference between a ship's location and the reference point of Greenwich, sailors could calculate their longitude with unprecedented accuracy. Through his innovative and groundbreaking work, Harrison revolutionized navigation and transformed the world of seafaring. His chronometers not only saved countless lives and ships but also opened up new possibilities for exploration and trade. Harrison's story is a testament to the power of human ingenuity and perseverance in the face of seemingly impossible challenges. His legacy continues to inspire and fascinate generations of scientists, historians, and adventurers alike.
