    sundial clock

    first clock was a sun dile invented in the early 300's invented by Babylonians. They used it by using the shawdow to cast a time. this was useful for only a little bit because they could not tell time at night.

    waterdial

    the first water dial clock invented in the early 500's invented by Archimedes and used by the Eygptions but they could not invent it because there was no water in the desert.

    hourglass

    The hourglass was made inbetween the 500's and the 700's. It was invented by a man that said we can not make a waterdial because there is no water were we live ( Egypt ). So he invented a glass bottle that came to an narrow passage in the middle which would make it hard for the sand to fall to the bottom and when it ran out u flipped it over.

    Minute Hand

    Jost Burgi invented the minute hand. Burgi's invention was part of a clock made for Tycho Brahe, an astronomer who needed an accurate clock for his stargazing.

  • Atomic clock

    Atomic clock

    An atomic clock is a clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS
