In Observing the Invisible, Kelly Cherry crafts poems that explore the ever-evolving realm of modern physics, confronting the invisibilities and mysteries of the material world. She leverages challenging ideas into a space of contemplative wonder as the book moves from external observation into an increasingly inward space of personal reflection and expression. Throughout, Observing the Invisible remains deliberate in its concentration on what cannot be, almost as if the poems are being erased even as they are being written. Acknowledging that such contradictions cannot sustain themselves for long, Cherry seeks out these difficulties and ultimately finds resolutions.--Lisel Mueller, author of Alive Together: New and Selected Poems, winner of the Pulitzer Prize for Poetr
