The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

Light sometimes appears to be "dragged" by the motion of the medium through which it is traveling. This phenomenon, referred ...

When a shape doesn't spin in a circular motion as expected in Microsoft PowerPoint, consider where the shape's axis of rotation is. You might need to force a new one.

Earth doesn't take a full 24 hours to spin on its axis — but humans use the sun to measure days. That's why our year is 365 days and not 366.

Its tilted axis of rotation gyrates in a circular motion, sweeping out a cone-shaped area in the process. You can cause a top or gyroscope to precess by gently tapping it while it’s spinning.
