Clock is the best invention in the world! The history of clocks is very long. There are many different types of clocks over the years. The word ‘clock was first used in the 14th century. It comes from the word for bell in Latin (“clocca”). The very first timekeepers were natural clocks such as the sun, moon and stars. Ancient people used sticks and stones to find out the time around 3500 B. C. When it was between 3500 BCE and 1949, the inventors improved clocks, and became the clock that we use now. Clock is the most helpful invention in the world.
Firstly, clock is magical that have different names and faces. Next, clock makes our life easier and the special quartz clock. Lastly, clock helps us to organize and manage our time. Clock helps us a lot. Therefore, it is the most helpful invention in the world! 4000 years ago, the ancient Egyptians used stone pillars and sticks called gnomon to find out the time. As the sun shines on an upright or tilted stick, people therefore measure the time of the day by the length of the shadows. It is the shadow clock. In 3500 BC, Egyptians built the sundial.

A sun clock is a clock that needs sunlight and sticks and stones to tell the time. First you need to put the stones in a circle. Second, put the stick in the middle of the circle and when the sun comes, you will know the time. Sun clock can Just comprehend the time when the sun comes up from the hill. Ancient people wanted to measure time at night as well as in daytime. They could not use sunlight to measure at night, so they created a water clock. Egyptians invented the water clock in 1400 BC. It was a stone bowl with a hole at the bottom.
They were made from two containers of water, one higher than the other. The bowl was filled with water. The water then travelled from the higher container to the lower container through a tube. As the water come out, its falling level indicated the passing of time. The Chinese inventor called Su Song developed an even better water clock in 1088. It took Su Song 12 years to build a water clock. The clock has 133 different clock Jacks to indicate the hours by having water dripping through the holes of the water clock. The water clock is powered by an eleven foot water wheel with 36 buckets of water.
The power comes from a water wheel occupying the lower part of the tower. Su Song designed a tool to stop the water wheel once every quarter of an hour, when the weight of the water is sufficient to trip a mechanism. The wheel rives the machinery of the tower to the next point in another cycle. The clocks water wheel turns 100 times a day. However, the next really big change in clock invention did not come until the breakthrough that happened 300 years later. As towns expanded and trade became more busy, people needed more accurate ways of telling the time.
The first mechanical clocks were in built in Europe in the late 13th century. It did not have hands or clock faces. Instead, they kept the time by striking a bell every hour. They were designed for use in churches. In 1510, Peter Helein invented a spring-powered clock, but it was not very precise. The first practical clock was driven by a pendulum, which was invented by an Italian scientist, Galileo Galilei, the pull of Earth’s gravity. Galileo realized that this could be used to measure time but the first pendulum clock was made in Holland by Christian Huygens in 1656.
It was a clock that has a swinging weight below the clock and used to keep the time accurately. The swinging weight will swing once in every second in order to keep the time accurately. However, the pendulum clocks had their problems. It would stop running after a while and has to restart. This problem was solved around 1840 when n eternal battery was fitted and by around 1906 the batteries could be fixed inside the clocks. Many inventors had more different ideas to improve clocks throughout the century. Pocket watch is one of the examples.
Peter Henlein, a German metalworker, in the early 16th century invented the first pocket watch but it had only an hour hand, and was expensive. The Industrial Revolution in the 18th and 19th centuries led to the mass production of pocket watches and a Swiss watchmaker firm could therefore make a cheaper pocket watch that many people could afford. The next major development in pocket watch echnology came in 1657, when the famous Dutch scientist and inventor Christian Huygens designed the balance spring assembly, which made the watch run more accurately and enabled the addition of the minute hand.
In 1927, a Canadian engineer, Warren Marrison developed a very large, highly accurate clock based on the regular vibrations of a quartz crystal in an electrical circuit. He found that the quartz oscillator used in this way was more accurate than the best existing mechanical clocks. Quartz clocks contain crystals of quartz which vibrate and act like pendulums. The vibration controls the speed of an electric motor which turns the lock hands. An America inventor, Isidor Rabi first proposed the concept of atomic beam magnetic resonance in clocks.
Based on Rabi’s concept, the first atomic clock was manufactured in 1955 by an English physicist Louis Essen and Jack Parry. Atomic clock is one type of clock used to measure the exact time by the vibrations created by atoms. As the demand for clocks increased, many specialist clockmakers grew up. Throughout the centuries, clockmakers and inventors tried hard to make the clock smaller and lighter. People do not need to carry a sun clock and a pendulum clock nowadays since we can carry mini clocks- wristwatches with s.
Also because of the advancement in technology, clockmakers used different energy sources to make clocks, such as solar energy, batteries, quartz and atoms. The first quartz watches were made in 1967 and the first digital watches in 1971. Today we can buy quartz watches which not does not only tell time and date but also have stopwatches and calculators. We can also buy solar powered watches today. We can also buy the most accurate watch now. Clock makes our life easier because we can go to work or go to school on time. People can keep their time with a watch or clock.
It makes our lives easier, for we can plan our time to do things like planning when to do homework, go to school, meet our friends or even go for a bath. Therefore, clock is the best invention in the world. From the ancient clock to the latest development of clock, it has been many thousands of years. Many scientists and inventors helped to change our modern lives. Invention of clock helps people to plan and organize their time. Since we have clock, we can have timetables such as school timetable, train and bus time table. It have a clock, everything will be messy and it may make the whole world become haotic.
If we do not have a clock, we would be late for everything, such as school and activities. It is hard to imagine a world without clocks. Today, time can be measured accurately. Clocks and watches are now very cheap to buy and are available in all shapes and sizes. Without it our lives will be messy and we could not plan our time effectively. Clock is therefore definitely one of the greatest inventions in the world. We have the most advanced technology in making clocks or watches nowadays. However, if we do not manage our time well, it is useless to have the most ccurate clock or watch with us.
What we actually need to do should be planning our time to the best so that we can be a good time manager. Therefore we need to learn the skills on time management. By doing so, we would always be a master but not a slave to time. References: Books 1. Navin Sullivan. (2007) Time. New York. Marshall Covendish Corporation 2. Mary and John Gribbin.
