Then from his mind into theirs there flowed smoothly a mighty stream of comprehension of cosmic phenomena. They hazily saw infinitely small units grouped into planetary formations to form practically dimensionless particles. These particles in turn grouped to form slightly larger ones, and after a long succession of such grouping they knew that the comparatively gigantic aggregates which then held their attention were in reality electrons and protons, the smallest units recognized by Earthly science. They clearly understood the combination of these electrons and protons into atoms. They perceived plainly the way in which atoms build up molecules, and comprehended the molecular structure of matter. In mathematical thoughts, only dimly grasped even by Seaton and Crane, were laid before them
