“In his great treatise, Electricity and Magnetism, Clerk Maxwell had remarked that we are often told that in science we must, first of all, investigate the properties of very small local places one after another, and only when this has been done can we permit ourselves to consider how more complicated situations result from what we have found in those elements. This procedure, he added, ignores the fact that many phenomena in nature can only be understood when we inspect not so-called elements but fairly large regions.”
