I heard a lot about questioning the "existence" of real numbers and if they are a realistic description of reality, but I kinda feel like a portion of that uncertanty should also be applied to integers as well. How does the notion of a discrete element relate to our current world-view of fields and waves? Can you truly have a "single thing", isolated from its externals, constituting a discrete element? What would that be? What can you put in a box and not have it influence the would outside (or the box itself as well), thus extending its reach and making it a part of a greater whole?
