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 ...

The rotation is slowing down due to tidal friction from the Moon, lengthening the day by approximately 1.7 milliseconds per ...

An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

In The Age of Miracles, Karen Thompson Walker’s newly released debut novel, the Earth apparently hasn’t received the same memo as most of its citizens: Instead of moving at a pace faster than ever, ...
