A new first: Scientists mimic nature's self-affinity using computer simulations

For the first time, researchers have simulated the process of surface roughness creation. This is a step forward in understanding the emergence of fractal characteristic of rough surfaces on many scales ranging from atomic to geological scales. The perspectives of their findings are far reaching. Controlling surface roughness is essential to the performance and durability of virtually all engineering applications. It may even be a step forward in earthquake prediction.
