in terms of mechanical concepts.
It is
by virtue of their physical properties that
electrons and other particles combine

This curtain seemed to be raised
by a few inches
in the nineteen twenties,
in those heroic days when de Broglie and Schroedinger de-materialized matter like the stage magician who makes the lady vanish from the box, while Heisenberg (1969) eased her out of the straitjacket of determinism and proclaimed that the principle of complementarity agreed «very nicely» with the mind - body dualism — the implication being that the particle aspect of the
electron was analogous to the body, its wave aspect to the mind.
We (and science
in general) start
by accepting the real existence of certain scientific objects — atoms,

There are basically two types of lines, those produced
by collisions between the atoms or ions and the
electrons in the surrounding gas, which are called collision lines, and which are very bright for elements such as oxygen, nitrogen and neon, and lines which are produced when ions capture free

in the interstellar medium: hydrogen and helium.
