The Concept of Time in Children
As is known, there are 3 dimensions on Earth. These are listed as length, height, and width. After Albert Einstein discovered the theory of relativity, physicists accepted time as the 4th dimension. While movement can occur in all directions in the first three dimensions, in time, movement can only occur forward. Time, unlike other dimensions, is conceptually abstract. It cannot be seen or touched. There is no before or after. Time is only experienced.
