In English
Man’s daily life begins with the sunrise and comes to an end with the sunset. Sun always rises in the east and sets in the west. Depending on this phenomenon, man determines the direction of east and west. When the sun rises above the horizon, we call it morning; and when it sets below the horizon, we call it evening. Every man’s life depends on sunrise and sunset. But if we look at the same phenomenon from another angle and realise that the earth is spherical, then all concepts of east and west disappear. If we stand on a table and if that table shakes, we shake a little. If the bus in which we are travelling shakes, we shake. If the car in which we travel shakes, we shake; but we do not feel anything when we stand on the earth which itself is moving at several thousands miles per hour. While this earth of ours moves at a very fast pace, along with other planets in the solar system, we do not even feel the motion of the earth.
