Clocks are everywhere. Whether it's used for waking up one morning, getting to a meeting on time, or knowing how much time you have left up to a certain point; clocks are used daily by everyone in a modern society. We rarely stop to think about the real meaning of a clock. For the most part, many simply view a clock as a tool to tell time and don't give it a second thought. However, the development of the clock has had repercussions throughout recent history and led to many technological advancements. Before the start of the 18th century, sea travel was extremely dangerous. While one could determine their latitudinal position (North/South Position) by measuring the angle of the sun at its highest point or, if in the Northern Hemisphere, by measuring the angle of the stars in the North (Calculation). However, there was no precise way to determine its longitudinal position (East/West) and it had to be done by dead reckoning. This sometimes led to disasters where navigators misplotted their positions and led the ship to its doom. This was the case with the Scilly naval disaster of 1707, where a British fleet of twenty-one ships led by Admiral Sir Cloudesley Shovell ran aground. The fleet, returning to England, believed it was sailing in complete safety off Ushant; a small island in the northwest of France. However, due to storms, the fleet was approaching the coast of Scilly, an archipelago located on the southwest tip of Britain. The fleet struck rocks, resulting in the sinking of four ships and the loss of 1,400 to 2,000 men, including Admiral Shovell (History). Partly as a result of this disaster, in 1714 the British parliament passed the Longitude Act of 1714 which created the Council of Lo...... middle of article ...... get this, scientists hope to one day understand this unified theory. Such a theory would constitute a major breakthrough and answer many unknown questions. Overall, although often overlooked clocks have played a central role, they have not only contributed to technological advancements but also shaped the culture of modern society. In the early 18th century, the invention of the precise marine chronometer greatly increased the safety of foreign travel and helped England create one of the greatest empires ever known. With the creation of the atomic clock, the GPS system was created, which increased military effectiveness and helped shape the MAD's nuclear policy. In the civil sector, GPS is constantly used to improve the safety and efficiency of certain works. In the future, atomic clocks could play a role in deep space travel and help develop a general theory of everything..
