ABSTRACT In this paper, we revisit Fick’s original diffusion experiments and reconstruct the geometry of his inverted funnel. Part I demonstrates that Fick’s experimental approach was sound and measurements were accurate despite his own claims to the contrary. Using the standard modern approach, we predict Fick’s cylindrical tube measurements with a high degree of accuracy. We calculate that the salt reservoir at the bottom of the inverted funnel must have been about 5 cm in height and the unreported depth o...
