The same QM principles apply. It's just plain quantum mechanics going on whether it's a particle of molecule, or which experiment is being done: *Quantum Cheshire Cat effect may be explained by standard quantum mechanics.* https://phys.org/news/2015-06-quantum-cheshire-cat-effect-standard.html @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
