Tribology keeps the world rolling
The study of friction and lubricants, called tribology, is an often-neglected field at the confluence of physics, materials science, engineering, nanotechnology and other fields. (How friction works at the microscopic level is not completely understood.) Tribology’s economic impact is immense — for example, a large part of a car’s energy consumption comes from friction between its mechanical components. And a hot question is how to reduce friction in wind turbines to enable them to withstand stronger winds.
