When we see stuff like these rotating ... It's called the angular momentum. The angular momentum of a single particle depends on both the momentum of that particle and its vector location from ...

We represent the angular momentum as a vector (I already said that ... I am going to approximate the Earth as a solid and uniform density sphere (which it isn't - see this example).

Figure 1: HOP sphere representation of vector vortex beams. In contrast to the complexity and challenges of producing OAM beams and vector vortex beams from lasers, the control of polarization or ...

Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum ... vector vortex beams, known as higher-order Poincaré sphere beams.

So, what would happen if Earth were to abruptly stop rotating? If the spinning were to stop, the angular momentum of every object on Earth would rip the surface apart, resulting in a really ...
