How does Brownian motion relate to modern scientific questions?
The motion I observed, though initially a curiosity, is now understood as direct evidence of the constant, random bombardment of particles by the molecules of the surrounding fluid. This phenomenon remains central to understanding diffusion, chemical reaction rates, and the behavior of colloids. It provides a tangible, observable link to the submicroscopic world, informing fields from materials science to the modeling of biological processes at the molecular level. The very randomness I documented speaks to fundamental kinetic principles.
