The development of a study of the guard at the time ... such as watches and science to ensure the accuracy of our time, to the point where every day is measured for each ... allows us to determine all day, every second.
The first lessons were developed 3500 BC when the Egyptians decided it needed its own way to organize for better days to follow all social interactions. To do this .. We have developed a clock shadow. Builds a largeObelisk ... square tower marks the day in the shade when the sun moves across the sky.
Atomic Clock Instructions
you could say it reflects the earliest sundials to the longest day of the year, a shadow. Finally, they realized they mark the number of days during each of the marks on the floor of the obelisk.
Not only about 1500 BC the Egyptians began with a sundial. Must design evolved over the years, but remainedbasically the same, and they are the most important shows for years. In fact .. done, but until 325 BC.
Then the water meter all I had to do was clear there was a bowl, fill a small hole and fill it with water. A drop of water leaking ... Symbols of the hull and the time intervals for each day that water has run the controls.
The second type of water clock was a man who fell into the water ... ReverseThe first type.
Another man was just a big bowl of water in a container. The ship had a small hole in the water, and the bowl of water in the tank, marking part of the day.
Can you imagine how many hours they were not very accurate ... but on condition that these companies ... find a way to establish a regular time that day to provide a set of effective social responsibility.
The next stepwas the first mechanical clocks ... with the weight of the rope, and before March 1 and back to move the weight of the beam. They were more effective than water ... but not much ... because he was on the force and the friction of the rope with weights and a bar, who never met a very comfortable.
Spring classes was the next step of the clock. Since the travel of less thanClocks back ... The people you love. They managed to hide their own tables and ... and bags. They did an excellent addition to the establishment by the beginning of the 1510th
Was the first truly accurate clock, the pendulum clock. Lessons precision lost at least 15 minutes a day to get lost in the final jump of 0.01 minutes less than great, it was a.
More details ... watches are very popular andToday ... quartz. died in 1920, and the market is still difficult because of their accuracy and price ... low, because they are not expensive to produce.
This atomic clock ", the hands are still on the market ... by far the most accurate clocks in the day.
In the past ... The second is always determined by the movements of the earth. The atomic clock has been foundsecond frequency oscillations of the cesium atom exactly 9192631770 ... Tone, standard based on atomic time.
So ... show a time when there was no reason in due time ... at a time when every second is marked exactly on every day ... Operations in life depends on this identification, the second ... The clock has developed a world of technology in the infinite bit "suspended each other ...the second.
Browse vintage watches is a reminder of the days when life was less intense, and perhaps we'll all Rose had more time to smell ... and hear those seconds tick.
