Following on from his award-nominated debut collection, On Light & Carbon further develops and deepens Duffy?s exploration of the relationship between poetry and science with work that strives to make unexpected connections between the intimate human dramas of everyday life and the grand backdrop and insights that science provides. Yet the title of this collection holds a double-resonance, examining not just the physics of light and life, but also the metaphysical meanings that such ideas hold in poems that engage, excite as well as move.
