Line Between Two Sphere Centers:
“Part of the problem is that people think of the 180-degree-straight-line diameter rather than of the two radii that constitute the diameter-- the two radii of the two separate but tangent spheres, end-joined at the intertangency point between the two spheres. Both aspects are equally deceptive.”
