Did you ever want to attend a famous lecture at MIT?

But you never did, because you never went to MIT, the plane tickets was too expansive to fly in for the weekend and simply you don't have the time. Well, you can attend a public lecture from MIT right from your couch. Technology school MIT has created MIT World, a free and open site that provides that provides on-demand video of significant public events at MIT. Lectures from some of the world's brightest people are at your fingertips.

I sat in on the Invention and Innovation: Emerging Technologies that Will Change the World: The Inventor View. It was interesting to hear Steve Wozniak (one of the founders of Apple Computers) talk about the characteristics of a good invention in the 21st century.
