The book presents an English translation of Johannes von Kries's 1886 work on the range theory of probability, offering a fresh perspective on its foundations. It challenges the principle of indifference and introduces arbitrary functions, while clarifying historical confusions. The narrative approach minimizes formulas, making the concepts accessible. Von Kries applies his theory to Boltzmann's statistical gas behavior and medical statistics, revealing limitations in traditional probability applications. It appeals to philosophers, historians, and practitioners in fields like econometrics and psychology.

This book presents the most complete translation to date of Erwin Schrödinger’s work on colorimetry. In his work Schrödinger proposed a projective geometry of color space, rather than a Euclidean line-element. He also proposed new (at the time) colorimetric methods – in detail and at length - which represented a dramatic conceptual shift in colorimetry. Schrödinger shows how the trichromatic (or Young-Helmholtz) theory of color and the opponent-process (or Hering) theory of color are formally the same theory, or at least only trivially different. These translations of Schrödinger’s bold concepts for color space have a fresh resonance and importance for contemporary color theory.
