> Our food classifications should be based on method of eating, not by shape! I agree Euclidean geometry isn’t the key to proper classification of sandwich systems. Rather we need to look towards physics and emergence. Sandwich emergence is the law or phenomenon that which occurs at sandwich scales (in space or time) but not at ingredients scales, despite the fact that a sandwich system can be viewed as a very large ensemble of ingredient systems.
