I’m always hearing snatches on the radio that intrigue me; sometimes I even follow up on them. One of my favorite sources for these snatches is “The TED Radio Hour” on NPR. As you may know, and as I’ve written before, TED Talks are a great source of short talks on a wide range of subjects. “TED” stands for “Technology, Entertainment, Design,” but you can shoehorn almost any topic into those three areas.
