Looking to delve into the world of solid-state chemistry? Why not check out this excellent introduction to the subject, provided courtesy of MIT and their OpenCourseWare (OCW) initiative. This is not just an introduction to chemistry class; it's a "chemistry-centered class that integrates examples from the world around us, in the arts and humanities, the human stories behind the science, and applications to engineering and emerging technologies." The materials provided here are from Professor Donald Sadoway's college course and visitors can view a complete set of lecture videos, read detailed course notes for most of the sessions, check out the homework problems, and also view a collection of external links for further study. This course is a MIT OCW Scholar course, designed specifically for independent learners, and as such is "substantially more complete than typical OCW courses, and include new custom-created content as well as materials repurposed from previously published courses." One of the custom features of this particular course is the online study group that allows users to interact directly with other persons using the course site. Visitors can also read brief session overviews and download all of the course materials at one time.
