Abstract
We present microscopic observations of the diffusion in water of micrometer-sized spheres confined between two walls. Deviations from the Stokes-Einstein law are observed, which for different bead diameters and different separations between the walls depend on a single dimensionless parameter. We compare numerical predictions with the experimental values.
