Concept of TIME (Part-3)

In Part-2 of the article we realised that our consciousness gets aware of time because of the events that keep occurring around us. We saw, that events occur in succession, one after the other. Their sequence of occurrence creates the impression of time in our consciousness. Gap between the occurrence of two events is called 'DURATION of time'. We measure time(rather, duration of time!) with the help of events.
Some events are periodic- they repeat again and again. For example, a pendulum swings from one end to the other again and again. We measure a duration of time with the help of such periodic events. The bob of a pendulum does not remain at one point all the times. So its being observed at any particular, say left extreme position, is followed by its disappearence from there. Then again after complition of one full cycle of swing, the bob reappears there.
