Billed as "Thousands of video lectures from the world's top scholars." The subjects cover astronomy, biology, chemistry, computer science, economics, engineering, English, entrepreneurship, history, law, mathematics, medicine, philosophy, physics, political science, psychology, and religion--a little something for all. I have watched a few and can say that they are quite good. Understand that these are not slick productions but classroom lectures and rather primitive.
