Abstract
The dynamics of relativistic strings is studied with emphasis on the close analogy with the transverse motion of the conventional stretched string of freshman physics. A constraint-free parametrization of the world sheet in terms of arbitrary wave packets moving along the string is given. In particular, it is found that for the initial condition of right and left moving wave packets in a collision arrangement, there is no scattering−each packet only experiences a delay upon passing through the other. Also discussed is the geometry of the spontaneous singularities generically arising for strings in two spatial dimensions.
