My dad, a mathematician, raised me to believe that mathematics is beautiful, so math is a part of my imaginative terrain. In my late 20s I wrote several 11-line poems because I wanted to create poems that couldn't be uniformly divided into couplets, tercets, or quatrains, 11 being a prime number.

For me, intuitive thinking means associative thinking; intuition causes us to introduce narrative or figurative elements into a poem before we're able to explain why those elements belong.

I wrote the poems in Charms Against Lightning one by one, over almost a decade, and I did not write them toward any theme or narrative. But once I really got serious about putting together a book, I began to see that in fact there were themes across the poems, if only because my own obsessions had brought me back time and again to the same ground. I realized that any ordering of the poems would determine how those themes developed over the manuscript, and how the collection's dramatic conflicts were resolved.

Our analytical faculties allow us to look critically at our writing and interpret it. Sometimes we make bold, impulsive edits to our poems, but most forms of precision and economy in poetry, it seems to me, are signatures of the analytical mind.

Maybe because I can't even put together an IKEA desk, I've never been tempted to think of my own poems as built objects - but I do sometimes imagine them as mathematical constructs.

When you recite you're giving a performance, in the way that an actor or a singer performs, and some poets are not interested in doing that, maybe because they're writing for a readership as opposed to an audience, or because they see poetry as a very private art.

As a species, we create tools to control our environment. What excites my imagination is wilderness: our materials' ability to escape our control.
