The importance of Interfacial and Colloid Science across the spectrum from industrial manufacturing to energy development to biomedical research to everyday activities from cooking to cleaning is beyond dispute. Still， it is to be found in relatively few courses， particularly required courses， in science and engineering curricula in our colleges and universities. More often， it is that chapter in one's physics or chemistry text that is never assigned. The early stirrings of a shift in curricula to include this material is underway， however， particularly as new tools and insights are rapidly emerging and it is recognized as the bridge to the new era of nanoscience and nanotechnology. This text is addressed to both undergraduate and graduate students in science and engineering programs as well as to practitioners， although even high school students should enjoy parts of it. Its evolving versions have been used， I believe successfully， in both undergraduate and graduate elective courses in Chemical Engineering at the? University of Washington， as well as in a variety of industrial short courses since the mid 1980's. It is now used as the text for a course in Interfacial and Colloid Science， with a significant laboratory component， that has just become required for undergraduate Chemical Engineering students at Washington as the Department embraces a shift toward molecular engineering and nanoscience.
