Clock information and links

  • A Clock is a device used to measure, verify, keep, and indicate time.
  • The Clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units: the day, the lunar month, and the year.
  • Devices operating on several physical processes have been used over the millennia.
  • Some predecessors to the modern Clock may be considered as"clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface.
  • There is a range of duration timers, a well-known example being the hourglass.
  • Water clocks, along with the sundials, are possibly the oldest time-measuring instruments.
  • Traditionally, in horology, the term clock was used for a striking clock, while a Clock that did not strike the hours audibly was called a timepiece ; this distinction is no longer made.
  • Watches and other timepieces that can be carried on one's person are usually not referred to as clocks.
  • During the 15th and 16th centuries, clockmaking flourished.
  • The next development in accuracy occurred after 1656 with the invention of the pendulum clock by Christiaan Huygens.
  • The mechanism of a timepiece with a series of gears driven by a spring or weights is referred to as clockwork; the term is used by extension for a similar mechanism not used in a timepiece.
  • The electric clock was patented in 1840, and electronic Clocks were introduced in the 20th century, becoming widespread with the development of small battery-powered semiconductor devices.
  • Analog Clocks indicate time with a traditional clock face, with moving hands.
  • Two numbering systems are in use: 24-hour time notation and 12-hour notation.
  • Most digital Clocks use electronic mechanisms and LCD, LED, or VFD displays.
  • For the blind and for use over telephones, speaking clocks state the time audibly in words.
  • The study of timekeeping is known as horology.
