Oh! That's nice to know about mining, making it safer for workers!
But there's still the environmental impact... A few years ago, I was talking with a mine engineer who seemed proud to say that they had to move a lake to mine. He claimed that simply shop-vaccuming fishes from one place to the other was good enough....
The only thing to keep in mind is that although particles are dimensionless (as far as we know), the do not exist without context. Spin relates to how a particle is linked to the rest of the world.
One way of seeing it is that spin can be represented by a "rotational polarisation" of the surrounding cloud of virtual particles.
I've helped build nuclear waste caskets, nothing is perfect but the amount of attention put into making it safe is incredible! The layers (and quality) of stainless steel welds would put your average steel bridge to shame....
But fission will always be limited (as in non-renewable). If everything was powered by nuclear, I'm sure we'd see even more awefull mining operations. Also, fusion should in theory be much better, if the thermodynamics of it end up working.
All macroscopic examples of spinor involve an object attached to the exterior world. Electrons having spin 1/2 therefore imply that they don't exist "by themselves" and are embedded in a larger field.
I'm not sure whether that would be the electron field of the electromagnetic field, or maybe all of the fields?
There's an argument to have about conservation of culture, which is a thing in itself. (Why do people want to preserve antiquities?) There must have been some awesome poems in Sanskrit that we'll never know.
Mostly apeaking, for me the simple fact of wanting other languages to die is a huge red flag of attempt at cultural erasure, like when the english tried to eradicate Scottish culture. Language erasure is a tool to marginalise those speaking it, and history shows that it never really end well...
When a language dies, a piece of hunan culture dies with it.
Letting a language die is allowing erosion of human culture. Forcing or encouraging a language to die (so everyone can use the best language that I understand) is colonialism.
Cutting it in half will expose the full content plus some stuff that's not meant to be exposed. Follow the instructions from the R link on that other comment.
You can't leave us hanging! Where can I watch it? 🐡🐧
