"The Theory Formerly Known as Strings," by Michael J. Duff. ScientificAmerican, February 1998, pages 64-69.

This article discusses string theory, one of the most important notions inmodern physics, and a candidate for its replacement, M-theory. These theoriesattempt to unite gravity with quantum mechanics to give a complete descriptionof physical reality. Edward Witten is one of the main proponents of M-theory,out of which can grow not just one but a variety of different string theories.
