http://www.openculture.com/freeonlinecoursesThanks to my friend Claudia for sharing this information with me and a few others!Here are her descriptive words about the site:”While this list is cross-discipline, the Science courses are listed toward the bottom as the list is in alphabetical order. Many of the courses are available through iTunes, university websites, or as YouTube links and are from universities such as MIT, Notre Dame, Johns Hopkins, UC Berkley, Yale, and more.”This is an exciting offering for those of us who are always trying to expand our knowledge base but just don’t have the time or the wherewithal to take a course of study right now.Enjoy!
