The topology and geometry of spacetime is expected to undergo violent quantum fluctuations at a scale known as the Planck scale (10 -33 cm).

It is shown how this notion arises in the context of simple examples of string theory. Moreover the fluctuations turn out to map to a statistical mechanical problem of a melting crystal.
