Dear Nikola,

I hope your weekend in Portsmouth made you and your parents happy.  I have been indulging in foolish and feckless thoughts about the search for the indivisible (a.k.a. atom) as the physicists' quest for the Holy Grail on which Leucippos and Democritus famously set out 2500 years ago. Is it obvious or is it crazy to point out that the only conceivable hypothesis of the indivisible is the geometric point, which has no dimension, no no length, no breadth, no depth, no substance, no reality, no being. The Rutherford model of the atom, as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the sun, is obviously not an indivisible structure, and has long since taken its place in the museum of superseded scientific theories. Instead we are now keeping ourselves busy with the quantum, costumed to look and act like the ancient indivisible point, which lets us while away our days playing hide and seek with something which cannot be present unless it is absent.
