We may now investigate the mathematical expression for the disturbance propagated in any direction from a small particle upon which a beam of light strikes.
The mathematical expression for this potential can in some cases be calculated or predetermined.
not quite keep up with the mathematical expression but tend to become more equal.
Proceeding on this suggestion, and misled by the mathematical expression which he had given to Weber's law, Fechner held that a conscious sensation, like its stimulus, consists of units, or elements, by summation and increments of which conscious sensations and their differences are produced; so that consciousness, according to this unnecessary assumption, emerges from an integration of unconscious shocks or tremors.
if a point of the body be restricted to lie on a given surface, the mathematical expression of this fact leads to a homogeneous linear equation between the infinitesimais f, 77, i, X,, s, v, say A~+Bi7+Ci~+FX+GfL+Hv=O.
