The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory

During the last thirty years of his life, Albert Einstein sought relentlessly for a so-called unified field theory—a theory capable of describing nature's forces within a single, all-encompassing, coherent framework. Einstein was not motivated by the things we often associate with scientific undertakings, such as trying to explain this or that piece of experimental data. Instead, he was driven by a passionate belief that the deepest understanding of the universe would reveal its truest wonder: the simplicity and power of the principles on which it is based. Einstein wanted to illuminate the workings of the universe with a clarity never before achieved, allowing us all. | 1 The Elegant Universe Superstrings Hidden Dimensions and the Quest for the Ultimate Theory Brian Greene -- 2 -- Contents Preface Part I The Edge of Knowledge 1.

Einstein was not motivated by the things we often associate with scientific undertakings such as trying to explain this or that piece of experimental data. Instead he was driven by a passionate belief that the deepest understanding of the universe would reveal its truest wonder the simplicity and power of the principles on which it is based. Einstein wanted to illuminate the workings of the universe with a clarity never before achieved allowing us all to stand in awe of its sheer beauty and elegance. Einstein never realized this dream in large part because the deck was stacked against him In his day a number of essential features of matter and the forces of nature were either unknown or at best poorly understood. But during the past half-century physicists of each new generation through fits and .
