When starting this ice challenge, most people just step on the side of the bowl and slide down to the bottom. Then you’re ...

One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are ...

I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...

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 ...

How can a horde of active robots be automatically brought to a standstill? By arresting their dynamics in a self-sustained way. This phenomenon was discovered by physicists at Heinrich Heine ...

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 ...

A simple snap of the fingers boasts some complex physics. The arm loads up energy and then releases it explosively, so that the middle finger hits the palm with a sharp smack. A team has now shown how ...
