I marvel at Radiolab when I hear it. I feel jealous. Its co-creators Jad Abumrad and Robert Krulwich have digested all the storytelling and production tricks of everyone in public radio before them, invented some slick moves of their own, and ended up creating the rarest thing you can create in any medium: a new aesthetic. Take the opening of their show on the mathematics of random chance, stochasticity. The first aesthetic choice Jad and Robert make is that they don’t say you’re about to listen to a show about math or science. They don’t use the word stochasticity. They know those things would be a serious turn off for lots of people. In doing this, Jad and Robert sidestep most of the conventions of a normal science show – hell, of most normal broadcast journalism.
