ABSTRACT
The origins of geometry are lost in the mists of time. However, it is clear that by the era of the great Greek Philosophers, a fairly wide range of geometric knowledge had accumulated and was finally formalized in Euclid's monumental work entitled Elements. Euclid and his Elements are often regarded as synonymous although, in fact, Euclid authored many other texts on widely varying topics in mathematics, physics, astronomy, and even music. 'Special theory' of relativity with all its implications, has been thoroughly tested in countless contexts throughout the twentieth century and is accepted by almost all concerned with the subject. In fact, to most physicists today it is counted as one of the two cornerstones of modern physics—the other being quantum mechanics. The fundamental connection between gravity and special relativity came via the principle of 'equivalence'.
