Curious about something? Google it. Look at it. But is curiosity simply information seeking? According to this exhilarating, genre-bending book, what's left out of the conventional understanding of curiosity are the wandering tracks, the weaving concepts, the knitting of ideas, and the thatching of knowledge systems—the networks, the relations between ideas and between people. Curiosity, say Perry Zurn and Dani Bassett, is a practice of connection: it connects ideas into networks of knowledge, and it connects knowers themselves, both to the knowledge they seek and to each other.

Zurn and Bassett—identical twins who write that their book "represents the thought of one mind and two bodies"—harness their respective expertise in the humanities and the sciences to get irrepressibly curious about curiosity. They identify three styles of curiosity—the busybody, who collects stories, creating loose knowledge networks; the hunter, who hunts down secrets or discoveries, creating tight networks; and the dancer, who takes leaps of creative imagination, creating loopy ones. Investigating what happens in a curious brain, they offer an accessible account of the network neuroscience of curiosity. The book performs the very curiosity that it describes, inviting listeners to participate—to be curious with the book and not simply about it.
