Oscillation of course is the translational (orbital, back and forth or to and fro) motions of an atom. It goes without saying vacuity or vacuum (less pressure) is the seeming opposite state of pressure and figures into this law but is not mentioned. Common sense. This is not unlike standard thermodynamics. Thermodynamics permeates Keely’s work with his etheric vapor, sound and vibration, etc. Expansion and contraction are fundamental dynamic states at the core of All That Is. Learned the principles and laws of thermodynamics with Bjerknes Effect (Laws of Attraction and Law of Repulsion) and you are well on your way to understanding Keely, Russell and Le Bon.
