Janna Levin is a theoretical physicist studying the shape of the universe, and whether it is finite or infinite. And she's written a novel that poetically evokes the boundaries where mathematics presses on grand questions of meaning and purpose in human life. Such questions, she says, helped create the technologies that are now changing our sense of what it means to be human: How do we know what is true? And how free are we, really?
