I spent my Sunday afternoon vegging out and watching TED talks videos.  For those of you not familiar with it, TED (Technology, Entertainment, Design) is an annual conference of ideas, and has featured the likes of Stephen Pinker, Brian Greene, Al Gore, Stephen Hawking and many other fascinating thinkers and doers.  Participants are invited to give an 18 minute talk on an idea that they feel needs to be shared, and videos of these talks are available to freely view and distribute from the TED website.

Here’s one of my favourites, from the 2008 conference:  Joshua Klein on the impressive intelligence of the common crow, and the inventive way in which he put that intelligence to good use for the benefit of both human and bird.
