At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...

Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and when ...

The friction between a silicon ball and silicon wafer was measured in the experimental set-up shown on the left. The new research demonstrates that there is a direct relation between two effects: the ...

Friction, though familiar in everyday life, remains a complex phenomenon—especially at the microscopic level. Scientists long believed it arose from rough surfaces rubbing together, where tiny bumps ...

Despite the fundamental and practical relevance of dissipative interface phenomena and its long history in science, the complexity of the highly out-of-equilibrium processes across confined sliding ...

Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense rules we experience every day, where water pours, syrup sticks and coffee ...

Picture yourself at a busy pedestrian crossing. When the light is red, everyone waits -- until one person starts to cross. Soon, others follow, and eventually everyone follows the crowd and crosses.

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...
