Disc One-Pt. One: "Einstein's Dream"; Pt. Two: "String's the Thing". Disc Two-Pt. Three: "Welcome to the 11th Dimension". This series explores the long-sought "theory of everything," which eluded even Einstein -- gets a computer-animated explanation from bestselling author-physicist Brian Greene, of Columbia University, when NOVA presents the nuts, bolts, and sometimes outright nuttiness of string theory. Also known as superstring theory, the startling idea proposes that the fundamental ingredients of nature are inconceivably tiny strings of energy, whose different modes of vibration underlie everything that happens in the universe. The theory successfully unites the laws of the large -- general relativity -- and the laws of the small -- quantum mechanics -- breaking a conceptual logjam that has frustrated the world's smartest scientists for nearly a century.
