While I was recovering from the worst flu of my life last week, my husband decided to take over my blogging research duties. He found a real gem: Academic Earth, a collection of university lectures posted online.
Take a one-off lecture or an entire semester's worth of classes; it's up to you. How about "The American Novel Since 1945"? Not your style? Try "Private Equity and the Financial Crisis" or "The World is Flat 3.0" with Thomas Friedman. A lecture on elliptical orbits from MIT? You can see why I'm excited about this resource!
