As part of the OpenCourseWare (OCW) initiative, the University of Michigan is offering this course as part of their generous contributions to the OCW archive. The course uses an open textbook, and all of the materials here were written by senior chemical engineering students, and subsequently reviewed by graduate students and faculty associated with the course. Visitors can click on one of four sections here: "Overview", "Highlights", "Materials", and "Sessions". The "Overview" provides a bit of introduction to how the course is structured, and "Highlights" talks a bit about the open textbook used in the course. The site has some great bells-and-whistles, including a "Live Study Group" area. In the "Sessions" area visitors can listen and watch all of the lectures from the course, and they can also download them for future reference.
