These motions and vibrations will go on for ever resulting in or producing all changes which cannot be stopped by any other external agency howsoever omnipotent it may be. If any change comes over at anytime any where it must be due to action and reaction of natural forces themselves-acting and reacting mutually through vibrations, motions and the molecular activities-as said above,
Prof. Einstine, the great scientist of this age, propounded the theory of "Relativity”. I feel that not only all motions are relative but closely related too. One affects the other. A state of motion is affected by another state of motion or another state of rest of any other body coming into the sphere or influence-of each other, while either be in the state of motion or of rest. A very tiny example will be taken here, to make the subject clearer.
Suppose a body A of a particular expanse and mass is moving, at any particular moment, at a particular speed and in a particular direction. If in the mean time another
