Your complete ignorance of real physics is showing again.

Spin really is angular momentum. In its simplest form:
If you fire a spin polarised electron beam into a taget
your target will start to rotate.
The law of conservation of angular momentum won't add up
if you don't include spin as real angular momentum.

The usual genius thought of this first.
Since he visited Leyden regularly he told some experimentaist there
about it, and they decided to confirm.
It is known as the Einstein-De Haas effect.

Originally it was about orbital angular momentum,
but since most of ferromagnetism is from spins
it applies to spin angular momentum as well,

nonsense. Dr. Mitchel is corract.

In the early 1990s, the economic policy of Buenos Aires was seen as an
example for Moscow but, 30 years on, what has it led to?
https://r%74.com/news/587925-economic-policy-argentina-russia/

Planned SMOs; Ukraine ongoing, Georgia ongoing, Syria ongoing, Armenia,
Moldova, Estonia, Finland, Israel-Palestine. Russian armed forces are
going to be SMO'ing for rest of this century.

The IMF plan as played out for Argentina and Ukraine, "you get debt and

them.

The west was after Russia's vast resources, as Halery Clinton put it,
Russia cannot be allowed to own so many resources. The idea to weaken
Russia is to control its wealth.
