Yesterday the New York Times ran a story about MIT physics Professor Walter Lewin who has become a video star at age 71 thanks to his popular online physics courses.
Another professor who deserves five-star status is UC Berkeley history professor Margaret Anderson, who just finished an outstanding series of podcast lectures on German history. As an extra bonus for do-it-yourself Web scholars, Dr. Anderson has posted the lecture notes and PowerPoint slides for her lectures. To get to the lecture notes, click on this link, and then search for History 167B.
Be sure to check out her lectures on romanticism and turn-of-the-century Vienna.
