The history of time evolution of the clock

Messenger We live in a world where time is all important. In his bestseller, A brief history of timephysicist Stephen Hawking reminded us that:

The history of time evolution of the clock

The Evolution of the Clock Timeline created by zsterling13 The Sun Dial The sun dial was the very first device mankind used to tell time. The Egyptians were the first to create and use this device.

They uinvented it at about BC. The sun dial worked by creating a shadow from the sun that was used to line up with a line written with a certain time of day.

Sun dials were always made out of some type of hard material. Most oftenly stone and rock. Retrieved October 4,from http: The time the water constantly travels is then measured to be put into time.

The most common type of water clock was having the water of in one bowl empty out into something that would catch the water. The most common example of this is another bowl catching the water until it overflowed;however, the are some examples that show other ways.

One way was of having a wooden bowl float in a well with the water draining out. The water clock was used much more than the sun dile because of how everyone had to have water.

So since everyone had water they could easily measure the time by using the water. This tells how long it has been since it has been lit by measuring its height. These there are examples of how people used a frame, like in the picture, to measure the height of the candle, or they would have the height written in the wax.

The candle clock method was not very efficient though. There are many different types of waxes and incenses, and they do not all melt at the same rate. Because of this candle clocks were not very popular for tracking time. It invovled having weights to use the force of gravity to help turn gears in the clock.

They only had an hour hand that was used, and it would strike bells to help tell the time. The first public one appeared around A.

These first mechanical clocks were not very accurate, but they were still thought to be accurate at the time of their invention.

Jan 1, The Weight Clock Cont. Clock a History - Timekeepers. Retrieved October 9,from http: The sand was contained in a glass jar like object in the shape of an eight.

This was one of the most popular methods of telling time that did not invovle any mechanical parts. It is easy to transport due to its size and how it contains the fine sand, unlike previous candles with dripping wax, spilling water, and heavy sun dials made of stone.

Jan 1, Young, T. It was originally constructed by Peter Henlein, a German engineer. There were ealier versions of a mechanical clock; however, none were as successful as Henlein's.

This also the first portable clock, and it later turned into the first watch by having a piece of string tied around the wrist. Jan 1, The History of Timekeeping. Retrieved October 5,from http: Cuckooclock World, the world of cuckoo clocks. Cuckooclock World, the World of Cuckoo Clocks. It works by having a battery to send electric currents through a coil to cause a vibration.

This vibration causes a magnet to change the frequencies so a small pin moves along a small quartz crystal to harness the extreme vibrations of the crystal into moving gears and other mechanical parts. The quartz clock is also the most common type of clock used for time keeping.

Jan 1, The Quartz Clock Cont. The quartz clock is still the most commonly used clock of the public. It is still used in watches, timers, computers, and almsot every device of the modern age.

The History of Timekeeping.Time, a central theme in modern life, has for most of human history been thought of in very imprecise terms. The day and the week are easily recognized and recorded - though an accurate calendar for the year is hard to achieve.

Publication History ~ This brief essay on the history of timekeeping was conceived and written by Kent Higgins and illustrated by Darwin Miner, of the Program Information Office of the National Bureau of Standards (now NIST) in about , and printed in booklet form for distribution to .

The cuckoo clock is different from the mechanical clock, because it was made entirely of wood. This shows that the clocks are now not only used for time keeping, but .

Throughout history, clocks have had a variety of power sources, including gravity, springs, and electricity.

Mechanical clocks became widespread in the 14th century, when they were used in medieval monasteries to keep the regulated schedule of prayers. By: Bri Frys and Rachael Swenson Evolution of the Clock 2. The First Clock The first recorded clock was invented in BC by the Egyptians, they used a sundial, which works by the sun casting a shadow on a triangular pointer (much like the hour hand on our modern clocks).

The History of Timekeeping: Wrist Watches. In today’s episode, we’ll take a step back in order to understand how the final stage in the evolution of timekeeping devices came about: for the first time in history, a clock so small it could actually be held in one’s hand.

However, there was still no solution in sight to the problem.
