Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense ...
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 ...
With mild temperatures and ample snow, much of Alaska is now primed for cross-country skiing. It’s a sport for all ages, made possible by friction. According to Samuel Colbeck, a retired geophysicist ...
For the first time, ETH Zurich Materials Scientists have measured the rolling friction of microscopic, micrometer-sized particles. These measures allow them to better understand common items like ...
Have you ever noticed when moving furniture that heavy objects are easier to move if you rotate them at the same time as you push? Many people intuitively do this right. An international research team ...
