Dynamics of a Tracer Particle

  • Herbert Spohn
Part of the Texts and Monographs in Physics book series (TMP)


A Brownian particle suspended in a fluid follows a rather irregular path because of the incessant bombardment by fluid molecules. The thermal motion of the fluid molecules is transformed into the erratic motion of the Brownian particle. The physical understanding of the cause for Brownian motion emerged slowly during the second half of the nineteenth century. A. Einstein developed a molecular theory which was confirmed through the beautiful experiments of J. Perrin. This achievement constituted an important step in the struggle for an atomistic understanding of matter.
