Principles of Chemistry Links (videos): OCW (RealPlayer), iTunes, YouTube Links (additional): Course Home Page Review: While this isn't exactly a physics course, the first third of this course covers some of the more important aspects of physics discovered towards the end of the 19th century and the first half of the 20th century. Above and beyond the information provided, the instructor (Sylvia Ceyer) has to be one of the most energetic and enjoyable people I've seen. Even if you already know this material, just getting to watch her presentation of it is worth the time. I haven't watch the full set of lectures as my interest dropped off as it started becoming more of a chemistry course and the second instructor (Christopher Cummins) started taking over the lectures. But again, I highly recommend watching about the first third of this course. Donations/Home Pages: MIT OpenCourseWare
