Spin squeezing

Spin squeezing is a quantum process that decreases the variance of one of the angular momentum components in an ensemble of particles with a spin. The quantum states obtained are called spin squeezed states. Such states can be used for quantum metrology, as they can provide a better precision for estimating a rotation angle than classical interferometers. (Wikipedia).

Spin Art... centripetal force..."centrifugal" force // Homemade Science with Bruce Yeany

Spin art has been a popular device in the arts and science over the years. It is rather simple, spin a piece of paper at high speeds, splash some paints on it and then stop it and admire the results. It can be a nice piece to start a discussion on the application of centripetal forces,

How Does The Earth Spin?

One of the most common physics misconceptions is that an unbalanced force causes constant motion. In truth, an unbalanced force leads to changes in motion - accelerations.

Spinlaunch Throw Rockets into Space (with something which looks like Nikola Tesla turbine)!!!

The concept behind that system is simple. Essentially, SpinLaunch wants to get to orbit by using a large, vacuum-sealed chamber and a hypersonic tether to spin a spacecraft at a high enough velocity up to 5000 miles per hour to escape the atmosphere. That means no rocket, no rocket engines
