"...can be highly recommended as a textbook for interested students but as well for researchers in the strongly developing field of colloid dynamics." --Colloids & Polymer Science

One of the few textbooks in the field, this volume deals with several aspects of the dynamics of colloids. A self-contained treatise, it fills the gap between research literature and existing books for graduate students and researchers. For readers with a background in chemistry, the first chapter contains a section on frequently used mathematical techniques, as well as statistical mechanics.

Some of the topics covered include:

Brownian Motion of Non-Interacting Particles. Introduction. The Langevin equation. Time scales. Chandrasekhar's theorem. The pdf on the diffusive time scale.
