An Efficient Knowledge Clustering Algorithm,ot as rapid, as the distance decreases (it is roughly proportional to its sixth power). This has important consequences: whereas repulsive forces practically cease to be effective at distances greater than the length of chemical bonds, attractive forces are not negligible even at distances of about

A Brief Comment on the Development of the Theory of the Chemical Bond,able agreement with modern knowledge of the quantum theory of the chemical bond and with direct structural determinations using electron or neutron diffraction and .-ray analysis. Only in the theory published in 1916 by Kossel and Lewis did electrons assume a decisive role in concepts of the origin

,The Time-Independent Schrödinger Equation,of physics. It is true that we can proceed from the classical law of conservation of energy and, through a number of modifications (some of them inconceivable from the point of view of classical mechanics), arrive at the Schrödinger equation (“derive it”). However, this procedure does not possess th
