Finnish researchers find explanation for sliding friction

Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, but the fundamental origin ...

Ultra-cold atoms may wade through quantum friction

Theoretical physicists studying the behavior of ultra-cold atoms have discovered a new source of friction, dispensing with a century-old paradox in the process. Their prediction, which experimenters may soon try to verify, ...

In helium-three, superfluid particles pair 'like a dance in space'

Picture a nanoscale dance floor full of independently moving particles. When things really start to heat up—or, in this case, cool down—particles partner off, but on opposite sides of the space, "dancing" in synch as ...

'Tangled' physics

Disney's new movie, "Tangled," features the familiar fairy tale character of Rapunzel. The new film promises many twists on the beloved tale, but her long locks will remain prominently featured.
