imate Theory" (W. W. Norton & Company, 1999), written by Prof. Brian Greene, a well-established string theorist. * The Official String Theory Website: An excellent introductory site for the nonspecialist, including RealAudio interviews with leading string theorists, and a tour of the Big Bang. * The Elegant Universe: The companion site for the 3 hour PBS series based on Brian Greene's book. You can even watch the series online. (Unfortunately, it is nowhere near as good as the book! It is visually stunning, but the physics content is extremely low and the approach is excessively propagandistic. You can read a critical NY Times review of the series here.) * Particle Adventure: A very nice tour through the main ideas of the Standard Model of particle physics.(Also available in Spanish and other languages). * The Science of Matter, Space and Time: Another nice presentation of the concepts of particle physics. * Einstein's Unfinished Symphony: An article on string theory that appeared recently in TIME magazine, on occasion of TIME's designation of Einstein as the person of the 20th century. * Strings '00 Pictures: Photos of some of the world's leading string theorists, at the most important yearly conference on the subject (see also the ITP M Theory Program and Strings 96 pictures). * Black Holes, Strings and Quantum Gravity: A public lecture by Prof. Juan Maldacena, undoubtedly the most influential string theorist in the last few years (also available in Spanish). * Superstrings! Home Page: A nice site where many aspects of string theory are explained. * Duality, Spacetime and Quantum Mechanics: A public lecture by Prof. Edward Witten (IAS Princeton), arguably the world's most influential theoretical physicist, and a leading contributor to string theory * The Theory of Strings--- A Detailed Introduction: An extensive description of the basic ideas of the theory, by Prof. Sunil Mukhi, a leading string theorist. * String Reviews: List of downloadable review articles on various topics in string theory. Most of them are highly technical, but some of the articles in the "Colloquia/Semipopular" category are intended for a wider audience. * String Theory and the Unification of Forces: An explanation of the ambitious goal of string theory, by Prof. S. Mukhi. * The Second Superstring Revolution: A (somewhat technical) report on the latest developments in string theory, due to Prof. John Schwarz, one of the fathers of the theory. * Black Holes, Quantum Mechanics and String Theory: A series of 10 lectures on string theory, intended for the general public, by Prof. Finn Larsen. * ITP Teachers' Educational Forum on String Theory: Is it the Theory of Everything?: A set of lectures on string theory, intended for highschool teachers. * M-theory, the theory formerly known as Strings: A brief introduction to some ideas of the theory, presented by the Relativity & Gravitation group at Cambridge University. * String Theory in a Nutshell: A brief account of string theory, including some words on the latest developments, by Prof. J. M. Figueroa-O'Farrill. * What is String Theory?: A longer introductory description of the basic ideas of the theory, due to K. LLoyd. * Superstring Theory: An explanation of some of the ingredients of the theory, written some time ago by Prof. Brian Greene, for the graduate program at Cornell University. * String Theory: A short introduction to string theory by Prof. Robert Dijkgraaf, written for physicists. * M-Theory: strings, duality and branes: a non-technical article by Prof. J.P. Gauntlett, which appeared in Contemporary Physics
