Coursera

Daphne Koller is bringing courses from top colleges online, free for anyone who wants to take them.

"Coursera is committed to making the best education in the world freely available to any person who seeks it. We envision people throughout the world, in both developed and developing countries, using our platform to get access to world-leading education that has so far been available only to a tiny few. We see them using this education to improve their lives, the lives of their families, and the communities they live in."
