The Earth’s rotation on Aug. 5 may be about 1.25 milliseconds quicker than the full 86,400 seconds of a 24-hour day.

Magnetic field can speed up ultrafast laser-driven demagnetization in a novel 2D magnet Fe3GeTe2, revealing a universal ...

Abstract: Based on the topological charge matching principle and mode coupling theory, the higher-order orbital angular momentum (OAM) generating mechanism in a helically-twisted anti-resonant fiber ...

In fact, only three factors can be used to define a black hole: its mass, its angular momentum and its electric charge. In ...
