If local causality is a property of the interaction, separability is a property of the ontology of matter: as we have seen before, in classical mechanics, the properties of the whole are given by a suitable combination of the properties of its parts. In quantum theory instead, given entanglem...
Chemistry is the study of matter and how it changes. Matter is everything that has mass and takes up space, like the air we breathe, the water we drink, and the objects we use every day. Chemistry helps us understand what things are made of and how they interact with each other. ...
