" In the world of physical matter, whether one is looking at the largest star that floats through the heavens or the smallest grain of sand to be found on earth, the object under observation is but an organized collection of molecules, atoms and electrons revolving around one another at inconceivable speed. Every particle of physical matter is in a continuous state of highly agitated motion. Nothing is ever still, although nearly all physical matter may appear, to the physical eye, to be motionless. There is no "solid" physical matter. "

― Napoleon Hill , Law of Success
