### The History of Telling Time

In today's fast-paced world, time is the most important necessity of our lives. The importance can be measured with the fact that in the matter of nanoseconds, success can be converted into failure. However, looking back on the history of time, there were various methods to tell time. These observations were all about reading the stars high up in the heavens, the changes in the seasons, and also by the presence of day and night. Afterwards, one of the earliest of all devices to tell time was the sundial. The sundial is looked on as being a form of a sun-powered clock. Ancient civilizations such as the Sumerians, did have this knowledge, but when the culture died, knowledge was lost along with many other aspects of the civilization unfortunately. Another piece of brilliance was the hourglass, which is another form of early timekeeping device that was used in ancient times. The hourglass was constructed from two separate glass bulbs that were rounded. These two glass bulbs were connected by a neck of narrow glass that was situated between the bulbs. This hourglass contained particles of sand within it, and when it was turned upside down, a measured amount of sand particles would drop down from the top part of the glass to the bottom part of the glass. This is how the story unfolds when we talk about the history of telling time.
