First appearance of Helmholtz’s dissertation in which the German physicist derived the Ostwald–Freundlich equation and showed that Kelvin's equation could be transformed into the Ostwald–Freundlich equation. The German physical chemist Wilhelm Ostwald derived the equation apparently independently in 1900" however, his derivation contained a minor error which the German chemist Herbert Freundlich corrected in 1909. The Ostwald–Freundlich equation governs boundaries between two phases specifically, it relates the surface tension of the boundary to its curvature, the ambient temperature, and the vapor pressure or chemical potential in the two phases.

Il a notamment apporté d'importantes contributions à l'étude de la perception des sons et des couleurs ainsi qu'à la thermodynamique. - Helmholtz a vécu à une époque propice à développer lexpérimentation grâce à un arsenal dinstruments de plus en plus performants, qui prolongent, démultiplient, amplifient, accélèrent le regard des scientifiques sur la nature des phénomènes (et dans ce cas précis, des phénomènes sonores) pour mettre en évidence les explications de certaines observations : la technique a permis de transcrire sous une forme objective des phénomènes inexpliqués ; ainsi, lacoustique progresse considérablement et Helmholtz fonde l'optique physiologique et la psychophysique.
