Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

How much do you know about friction? Jennifer R. Vail's charming, if sometimes technical, "biography" of the force showcases its amazing and largely overlooked role in everything from climate change ...
