The 2009 TED conference, which featured a long list of well-known speakers, wrapped up on Friday. And now you can watch two of the key presentations online. First, and featured above, you'll get Bill Gates, Microsoft founder and now major philanthropist, talking about how to change the world through education and disease prevention. It's a good 20 minutes, and it will particularly interest any educators who read this blog. Next, Bill Gross, founder of Idealab, gives you 20 minutes on the groundbreaking work being done in solar energy.
We've added the Gates talk to our list of YouTube Favorites. Also, you'll find videos from TED on our list: YouTube Education: 80 Intelligent Video Collections.
