This NOVA website "introduces string theory and Albert Einstein's dream of unifying the forces that underlie all phenomena in the physical universe." Visitors can learn about the concept's possible role in unifying the four forces of nature. Students and educators can watch fascinating slide shows of physicists working with particle accelerators; interesting animations of resonance affects on cotton string; the three-hour mini-series, The Elegant Universe; and much more. The Teacher's Guide can help users take full advantage of the educational value of the materials. Anyone curious about the idea that the world can be made of numerous dimensions and made out of strings will enjoy this site. This site is also reviewed in the September 17, 2004 _NSDL Physical Sciences Report_.
