‎First appearance of Fick's importent paper in molecular physics in which he annouced his two laws of diffusion.Fick's first law relates the diffusive flux to the concentration field, by postulating that the flux goes from regions of high oncentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative). - Fick's second law predicts how diffusion causes the concentration field to change with time. (Wikipedia).First appearance of HELMHOLTZ'S fundamental paper in physiological optics in which he examined the sensitivity of the eye for the individual elements of the violet end of the spectrum" he was able to detect a whole series of distinct tones of purple: he alters the name 'invisible rays' to that of 'ultra-violet rays'" discussion of the relations of the wavelenghts of complementary colours and the intensity required if the mixture of simple complementarity colours is to produce white. He answered these questions quantatively. ""THE TREATISE (the paper offered), WHICH HAS BEEN FUNDAMENTAL FOR ALL LATER WORK OF THE SAME KIND, concludes with an inquiry into the validity of Newton's Colour Circle, which Helmholtz designates as one of the most brilliant inspirations of that great thinker.""(Leo Koenigsberge ""Hermann von Helmholtz"" pp. 131-133).‎

‎First edition of one of Fick's important works on the generation of heat in the muscle. He investigated this generation “with sensitive thermometers and related its magnitude to the effort of contraction produced. In order to increase accuracy in such investigations, he introduced the concept of methodology of isotonic and isometric determination of the process of muscular contraction (1867, 1882, 1889). ... Fick possessed a crystal-clear manner of thinking and writing. He was modest, without intellectual arrogance, and stood by his convictions fearlessly. ...” (DSB).Adolf Fick was professor of physiology in Zürich (1852-1868) and Würzburg (1868-1899).
