# gst: the intriguing dynamics of a crack

<< Cracks develop intricate patterns on the surfaces that they create >>

<< Although fracture mechanics predict that slow crack fronts should be straight and form mirror-like surfaces, facet-forming fronts propagate simultaneously within different planes separated by steps >>
