FOUNDATIONS AND CRITIQUE OF OSTWALD’S THEORY OF COLORS[^1]

Clemens Schaefer
1927 SovietRxiv: ru-192701.54591

In this article, drawing on the works of E. Schrödinger, Kohlrausch, and my own, I shall attempt to show in the most concise form that the so-called Ostwald theory of colors is incorrect in its very foundations and that its apparent simplicity is purchased at the cost of truth.

ELECTRICAL THEORY OF STRONG ELECTROLYTE SOLUTIONS[^1]

B. N. Finkel'shtein
1927 SovietRxiv: ru-192701.53033

The present article aims to examine the principal aspects of the modern electrical theory of solutions. The necessity of the division adopted below into two chapters, of which the first considers thermodynamic phenomena and the second electrical conductivity, is dictated by the consideration that th…

QUANTUM THEORY AND PHOTOGRAPHY¹

J. Eggert, W. Noddack
1927 SovietRxiv: ru-192701.35245

A special branch of photochemistry, of great technical and scientific interest, is photography. Interpretation on the basis of quantum theory is still at an early stage here. However, the results obtained, set out below, give hope for further progress. In any case, the possibility has arisen of a sc…
