&gt; You put a counter out there and you find &quot;clunk,&quot; and nothing happens for a while, &quot;clunk,&quot; and nothing happens for a while. It&#x27;s riot discretized at all, you never can measure such a tiny field, you don&#x27;t find a tiny field, you don&#x27;t have to imitate such a tiny field, because the world that you&#x27;re trying to imitate, the physical world, is not the classical world, and it behaves differently. So the particular example of discretizing the electric field, is a problem which I would not see, as a physicist, as fundamentally difficult, because it will just mean that your field has gotten so small that I had better be using quantum mechanics anyway, and so you&#x27;ve got the wrong equations, and so you did the wrong problem!<p>Things that far away are tiny, in a way. :)
