If you’re looking for something that’s out of the ordinary, try WNYC Radiolab. Here’s how they describe themselves:
“Radiolab believes your ears are a portal to another world. Where sound illuminates ideas, and the boundaries blur between science, philosophy, and human experience. Big questions are investigated, tinkered with, and encouraged to grow. Bring your curiosity, and we’ll feed it with possibility.”
And this is a pretty accurate description of the show. I download the podcasts and like listening at night. Gives me stuff to think about as I’m drifting off.
