Radio Lab, a production of New York’s flagship NPR station, WNYC, isn’t just the best science and technology show on public radio. I think it’s a contender for the best contemporary radio show, period. I discovered it in 2006, when it was already in its second season. But thankfully, MP3s are available at iTunes and at the show’s website, and because there are only five new episodes per year, I had plenty time in the car to get through the show’s entire third and fourth seasons.

If you asked me to say what Radio Lab is about in one word, I would say “perception.” Jad Abumrad, the show’s lively host and producer, is the son of an endocrine surgeon and a research biologist, a graduate of the music and creative writing programs at Oberlin College, and a longtime radio journalist. Clearly, the only fate open to a person with a background this eclectic is to invent new interviewing, storytelling, and sound-editing techniques to explore big questions at the boundary of neuroscience, evolution, and philosophy—questions like, Where’s the part of my brain that’s me? Why do some songs get stuck in my head? Where does guilt come from? What makes placebos work so well? Can we erase memories? Why do we find zoos so fascinating? Why are people who deceive themselves more successful than those who don’t? Why do we sleep/dream/laugh/lie/age/die?
