It seems obvious, then, that, cosmically speaking, everything spins—but this basic fact becomes downright bizarre in the head ...

In fact, only three factors can be used to define a black hole: its mass, its angular momentum and its electric charge. In reality, that charge will be neutral or very close to it, so in practical ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics.

Scientists have discovered a mysterious phenomenon that is accelerating the Earth’s rotation, leading to shorter days.In the ...

The angular momentum can be in a different direction than the angular velocity - but in this case, I is not a scalar quantity. Here is the short scoop on the angular momentum principle.

Angular momentum does not necessarily need to involve "real" bodily rotation in this context: Magnetic materials even have angular momentum when, seen from outside, they are at rest.

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

To compensate and keep angular momentum constant, the washer's angular velocity has to increase. The reverse happens when you loosen the string and allow the washer to move out farther.
