Exact insight into the relativity theory, from both philosophical perspective and general scientific perspective, for all those who are not conversant in theoretical physics and the mathematical apparatus, can be handy enough to understand the nuances associated with the subject. Einstein ideas were inspired basically by the brilliant theoretical physicist by then, Boltzmann. The physical meanings of Geometrical proportions can be understood better with the clarifications given in the Einstein theory. Plane, point and the straight lines are understood to wholesomeness with the basic conceptions of geometry. More or less solid ideas evolve and emerge from these basic definitions and clarifications explained well through Einstein theories.
