In fall 2011, Sebastian Thrun, a research professor at Stanford, and Peter Norvig, the top scientist at Google, teamed up to develop and teach a free, online course on artificial intelligence. Their aim, as Norvig said in an impassioned and compelling TED talk, was to develop a course at least as good as, if not better than, the course they teach together at Stanford.

IRA FLATOW, HOST:

This is SCIENCE FRIDAY. I'm Ira Flatow. Imagine stepping onto the Earth two billion years ago, taking a stroll along the shores of an ancient beach near the northern edge of what today is Lake Superior. You wouldn't see any trees. They didn't hit the scene until, oh, another billion-and-a-half years.
