Composition refers to the organization, arrangement, and combination of objects within the borders of a drawing space. For a great drawing, you want to bring the eyes of the viewer toward your center of interest within an aesthetically pleasing composition.
The idea that clockwise motion represents the forward motion of time so powerful that it's hard to look at such a watch or clock without having the slightly unsettling feeling that time is running backwards.
The Earth rotates at a high speed counter-clockwise as viewed from the North Pole. If an object starts at the North Pole and moves toward the equator in a straight-line path, for example, the object will appear to deflect to the right of its intended path because the earth is rotating under it as it moves. This is called the Coriolis Effect.
