They looked at images taken of 263 galaxies in the early universe, which were clear enough to gauge the direction of rotation ...

Scientists at Southampton University have made a significant advancement. They have successfully simulated the 'Black Hole ...

Scientists have raised concerns that the Earth's inner core may completely halt its rotation by 2040, according to a recent paper published in Nature. The study suggests changes are occurring deep ...

A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.

It was the first satisfactory demonstration of the earth's rotation using laboratory apparatus rather than astronomical observations. If you start a Foucault Pendulum swinging in one direction, after ...

it is known as the “instant center” of rotation for BD. You can observe this in the video shown below. Watch the velocity of point G on link BD. The direction of this velocity is perpendicular to the ...

As the rotation continues and that side of the coil moves down, the induced potential difference reverses direction. This means that the alternator produces a current that is constantly changing.
