 Can \(S(C)\) at some time be taken to represent an intrinsic property of a region of space corresponding to the curve C? There are two difficulties with this suggestion. The first is that the presence of the quantity e in the definition of \(S(C)\) appears to indicate that \(S(C)\) rather codes the effect of electromagnetism on objects with that specific charge. If in fact all charges are multiples of some minimal value e, then this would no longer be a problem: the value of \(S(C)\) for this minimal charge could then be viewed as representing an intrinsic property of a region of space corresponding to the curve C. If not, one could rather take
