Free Online University Courses
Recently, New York Times published a story about Prof. Lewin, “At 71, Physics Professor Is a Web Star“. Prof. Lewin is a physics professor in MIT. His courses have been No. 1 on the most downloaded list at iTunes U for a while.
If you don’t have iTunes like me, you can go to MIT’s OpenCourseWare project directly. You not only can watch some video clips of lectures but also download lecture notes, assignments and exams to test yourself. Some of lecture notes have been translated into other languages.
