Clock History Part two

The invention and innovation of the escapement was the next big piece in timekeeping history. In simple terms, the escapement allowed energy to be transferred from the energy element, to the time keeping element while allowing its movements or oscillations to be measured. This was important because if escapements did not exist, it would be nearly impossible to keep time mechanically.
      The earliest escapements were used in Greece in water clocks. a spoon supported by a counterweight would fill until it emptied into a basin. after so many cycles of this, a small round stone would be released. time could be measured based on how long it took the spoon to fill and empty, and a passerby could see the number of stones that were released (as they were kept neatly on a track for display, so it was known what time it was.) a method similar to this was used in the Tang dynasty in 725. This movement was based on a armillary sphere, which is a model of objects in the sky (plants, stars, etc). This was the first true clockwork escapement, but used for astrological purposes. it is suggested that this model of clockwork became the basics for the mechanical escapement, as well as the start of the European horology. Due to the fact that both of these sources utilize water instead of a mechanical source of energy, they are not true mechanical escapements, but the predecessor that made it possible.

Clock History Part one

              The ability to keep time is one of humanities most early inventions. Before what we know as a modern clock was made, the sun was used in order to keep track of time. By placing a  rod on a flat surface, it was possible to know the time of day by the use of the shadow hitting the surface. As the sun moved along the sky, the shadow would change at a consistent rate. This is known as a Sundial. The flaw of the sundial is obvious; it has to be day time, and sunny for it to work. The technical term for the stick that stands up is a Gnomon.
               Another early timepiece is the hourglass. Hour glasses are simple devices that use falling sand  in two glass domes. The amount of time it takes for all the sand to fall from one side to the other is known, so it was possible to keep track of time with this device. The size of the glass, the amount of sand as well as the size of the opening that connects the glass domes.
               A third example is the water clock. Similar to the hourglass, a simple water clock called a clepsydra  (water thief) could be used to keep track of time. In ancient Greece, its uses included time keeping for trials, time keeping for appointments and an athletic stopwatch as well as a tool to get a reading on a persons pulse
