The number of concepts and "wow" moments per minute in any hour-long episode of "Radio Lab" makes it one of my favorite radio programs (I either listen on WAMU-FM in D.C. or online). The momentum of the editing creates a fast-moving collage of sounds and ideas. Listening feels like you have a brain implant with a direct connection to hosts Jad Abumrad and Robert Krulwich -- whose narration and banter sounds as if they are in fact hard-wired to one another. The continuous use of music, voice and sound fragments -- down to the voicemail-like sponsor messages ("message one.... end of message") -- is ingenious. Listeners might feel like they are watching Carl Sagan's "Cosmos" in fast-forward -- but you can still follow the progression of information. And the Web site does such a good job of annotating each episode that an hour of listening can turn into hours of exploration. In fact, my sole complaint/suggestion is that the introductions of speakers and sources come so fast that I sometimes need to follow on the Web site to keep up with who's speaking. But that's a minor complaint. There's not a college- or university-town audience that would not gobble this program up.
