DESC: Perhaps the most remarkable aspect of Albert Einstein's genius was his ability to coherently communicate his seemingly complicated theories and ideas to the general public. This skill was never more apparent than in his 1916 publication RELATIVITY, in which he provides a simplified version of his most stunning and significant discovery. Einstein brilliantly outlines the series of insights and discoveries which led to his realization that the dimensions of the universe which we perceive, including time and space, are entirely variable, with the speed of light serving as a constant which makes certain calculations possible. Using lucid language and straightforward examples, Einstein allows the reader to share the joyful triumph he felt in becoming the first person to discern the beautiful simplicity hidden in the complex intricacies of our universe.
