Chemical Galaxy is a new representation by Philip Stewart of the periodic system of the elements, better known in tabular form as the periodic table, based on the cyclical nature of characteristics of the chemical elements (which depend principally on the valence electrons).
The pseudopotential is an attempt to replace the complicated effects of the motion of the core (i.e. non-valence) electrons of an atom and its nucleus with an effective potential, or pseudopotential, so that the Schrödinger equation contains a modified effective potential term instead of the Coulombic potential term for core electrons normally found in the Schrödinger equation.
