Throw an object that is out of its inertia, is directing it from beginning to end. By giving it a momentary existence, the object is left at the mercy of a behavior based on physical laws that dominate. His release by an initial force can be translated into energy and movement. The object stops moving when it is dominated by the force of gravity, which absorbs and leaves it in a state of quietness similar to its beginning, but different as is located in a different time. But what about its passing? For any object, this road is subject to the memory layout. However, in the present case quoted here does not. The pendulum, as tool, made a drawing and intervened a space and place. What accounts for a beginning and an end is the path, not the beginning and after the end of the pendulum motion.
