Time waits for no man. Keeping this mind, we set about inventing clocks to synchronize ourselves with lunar cycles. It was an impressive jump, beginning some 10,000 years ago when the Egyptians came up with sundials in 2100 BC. Sundials, or shadow clocks, first used by Sumerians, worked on the assumption of measuring the length of shadows to deduce time daily. Weather played spoilsport as on cloudy days, and as soon as the weeks changed, shadows wouldn’t correspond with the markings. The Romans attempted to do better by pilfering Cleopatra’s Needles, the tools used by Egyptians, but had to be satisfied with town criers announcing the shifting time. About 325 BC, the water clock followed sundials; a water clock was essentially a bucket of water with a hole in bottom to record slipping time but maybe hours. Numerous contraptions and versions followed, ultimately leading to clocks.
The term clock has its genesis in French word cloche, meaning bell. The first clock used weights to move gears, which in turn transferred the hands. The one problem was that somebody needed to reset the weights before weight was propped by an oscillating horizontal bar attached to vertical spindle with protrusions to serve as diversions. Soon, springs substituted weights, reducing the size of the clocks which could be carried, kept on a mantelpiece, or hung as wall clocks. Mechanical clocks and watches gave way to digital timepieces with quartz crystal, later to be surpassed with atomic clock.
Accuracy is the hallmark of atomic clocks, which are turning out to be more reliable and uniform in comparison with time deduced from the rotation of earth. Atomic clocks Operate by measuring the resonant frequency of a specific atom i.e., Cesium, Hydrogen, or Mercury, raising exactness over a billionth of a second per day. It’s this accurateness that’s made atomic clocks more dependable as Alarm clocks for national, scientific, or public purposes. At the International Telecommunications Union meeting, the Lets stop a problem before it occurs; debate was led by the USA, with France and Germany in tow. However, they didn’t prevail over the If it ai not broke, do not fix it, case as directed by the uk, together with China and Canada among the nations who were of similar mind. Each argument has its merits, but there wasn’t any straightforward instance which would bring the huge majority of undecided nations in favor of one or another. In the long run, it was determined to keep things as they are and wait to determine if a persuasive argument for change emerged at any time in the future.
