Clock A large variety of devices have been invented to measure time.
The study of these devices is called horology . An Egyptian device that dates to c. The T was oriented eastward in the mornings.
At noon, the device was turned around so that it could cast its shadow in the evening direction. The position of the shadow marks the hour in local time. The idea to separate the day into smaller parts is credited to Egyptians because of their sundials, which operated on a duodecimal system.
The importance of the number 12 is due the number of lunar cycles in a year and the number of stars used to count the passage of night.
They could be used to measure the hours even at night, but required manual upkeep to replenish the flow of water. The Ancient Greeks and the people from Chaldea southeastern Mesopotamia regularly maintained timekeeping records as an essential part of their astronomical observations.
Arab inventors and engineers in particular made improvements on the use of water clocks up to the Middle Ages. A contemporary quartz watchThe hourglass uses the flow of sand to measure the flow of time.
They were used in navigation. Ferdinand Magellan used 18 glasses on each ship for his circumnavigation of the globe Waterclocks, and later, mechanical clocks, were used to mark the events of the abbeys and monasteries of the Middle Ages.
Richard of Wallingford —abbot of St. Alban's abbey, famously built a mechanical clock as an astronomical orrery about The passage of the hours at sea were marked by bells, and denoted the time see ship's bell.
The hours were marked by bells in abbeys as well as at sea. Chip-scale atomic clockssuch as this one unveiled inare expected to greatly improve GPS location.
They can be driven by a variety of means, including gravity, springs, and various forms of electrical power, and regulated by a variety of means such as a pendulum. Alarm clocks first appeared in ancient Greece around BC with a water clock that would set off a whistle.
This idea was later mechanized by Levi Hutchins and Seth E. Initially, the term was used to refer to the marine chronometera timepiece used to determine longitude by means of celestial navigationa precision firstly achieved by John Harrison. More recently, the term has also been applied to the chronometer watcha watch that meets precision standards set by the Swiss agency COSC.
The most accurate timekeeping devices are atomic clockswhich are accurate to seconds in many millions of years,  and are used to calibrate other clocks and timekeeping instruments. Atomic clocks use the frequency of electronic transitions in certain atoms to measure the second.
One of the most common atoms used is caesiummost modern atomic clocks probe caesium with microwaves to determine the frequency of these electron vibrations.Download PDF file (application/pdf) (MB) Websites and online courses.
