We recall the theorem in its original form, and we highlight its generalizations to the relativistic Dirac particle and to a particle with spin and izospin. We argue that apparent classicality of the macroscopic world can probably be explained within the framework of standard quantum mechanics.</p>}, number={66}, journal={Philosophical Problems in Science (Zagadnienia Filozoficzne w Nauce)}, author={Arodź, Henryk Stanisław}, year={2019}, month={Jul.}, pages={73–94} }
