Computer simulation of the atomistic model of the particle. It can be seen that the material moved by the diamond needle accumulates at the edge of the particle and creates unique steps, which are later used as "guide rails" that return to the footprint, by diffusion, the material moved to the side. After a time the particle returns to its original shape. Source: Courtesy of the Technion.
