A new measure of roughness could advance earthquake geophysics

When two rocks interact with each other in a fault zone, the roughness of their surfaces could influence the outcome, including when they cause earthquakes. Still, the underlying mechanics of this relationship remain unclear.

Study links nano and macro aspects of everyday force

Without the force called friction, cars would skid off the roadway, humans couldn't stride down the sidewalk, and objects would tumble off your kitchen counter and onto the floor. Even so, how friction works at a molecular ...
