Time is precious for all of us. We manage our lives knowing what time it is. Choose Johnny from school at 4 o'clock, prepare tea 5 times for Phillip's arrival at 7.30. Finally sit down at eight for the next episode of the Eastenders. The world is ruled by a time when we do not like it, and wherever without it. It prevents us from being lazy and organizes our days.
Thus, the invention of time storage devices was very important for our history. But this is what slowly evolved. The shepherds used to tell the time by the position of the sun, and how we can now laugh when all we need to do today is to drop our sleeves and look at our wristwatches to find out the time for a second.
But how did a wrist watch change? This short excerpt will quickly review major innovations in watchmaking. Quartz watches and Atomic watches. Quartz watches used crystals to aid electronic movement of watches. The first people to introduce this to the world were the Sinclair group. Unfortunately, the initial attempt was disastrous. Digital watches looked slippery when they were slippery, but the battery lasted all ten days, making this invention useless for anything other than a fashion accessory.
But the attempt was made, and, obviously, it was not in vain, because only a few years later quartz watches appeared in Texas instruments, which saved time and power for a long time. In addition, they were ready to put it on the market at an affordable price.
Another innovation in the manufacture of watches is the atomic clock. Atomic clocks use the element cesium to keep it ticking. Cesium is a silvery metal found in granite and is known to scientists as the most electropositive element in the periodic table.
What is more surprising about cesium, and obviously another reason why it was used was that only a small amount was needed, and the clock would work for many years. Atomic clocks are used as the national standard for saving time in the United States of America.
In our time, we spend a lot of time. Our watches work fine, and if there is a problem, we usually require to know why. It ruins our life. Imagine if you had to try to stop your loved one so that he would leave the country at noon, only to find out when you are looking at your watch to stop. Like mobile phones, they are quickly becoming watches, moving from luxury to important.
