ABSTRACT
According to Erwin Schrödinger, the manifold of lights has a higher power than the power of the continuum, namely that of a space of functions; and hence an indefinitely large number of dimensions. With Hermann von Helmholtz, the measurement of colors takes a fundamental turn prompted by necessities of physiology of vision. Helmholtz was the first to construct a significant metric for the manifold of colors, based on Fechner’s law of relation stimulus sensation. The color measurements should satisfy the principles referring to the blackbody radiation, and thus, there is physics to address such measurements. As a matter of fact, this physics existed as such even at the time Schrödinger developed his theory. Helmholtz’s way of acceptance of the Fechner’s law, expressed in the special form of the Killing vector of the metric, is actually the mathematical basis of demonstration of Wien’s displacement law, and therefore, the general mathematical premise of Planck’s law of radiation.
