Poetical Matter examines the two-way exchange of language and methods between nineteenth-century poetry and the physical sciences. The book argues that poets such as William Wordsworth, Mathilde Blind, and Thomas Hardy identified poetry as an experimental investigation of natures materiality. It also explores how science writers such as Humphry Davy, Mary Somerville, and John Tyndall used poetry to formulate their theories, to bestow cultural legitimacy on the emerging disciplines of chemistry and physics, and to communicate technical knowledge to non-specialist audiences. The books chapters show how poets and science writers relied on a set of shared terms (form, experiment, rhythm, sound, measure) and how the meaning of those terms was debated and reimagined in a range of different texts. A stimulating analysis of nineteenth-century poetry and physics. In this groundbreaking study, Tate turns to sound to tease out fascinating continuities across scientific inquiry and verse. Reflecting that the processes of the universe were themselves rhythmic, he shows that a wide range of poets and scientists were thinking through undulatory motion as a space where the material and the immaterial met. The motion of waves, Tate demonstrates, was the exemplary form in the physical sciences. Sound waves, light, energy, and poetic meter were each characterized by a process of undulation, that could be understood as both a physical and a formal property. Drawing on work in new materialism and new formalism, Tate illuminates a nineteenth-century preoccupation with dynamic patterning that characterizes the undulatory as (in John Herschels words) not things, but forms. Anna Henchman, Associate Professor of English at Boston University, USA This impressive study consolidates and considerably advances the field of physics and poetry studies. Moving easily and authoritatively between canonical and scientist poets, Nineteenth-Century Poetry and the Physical Sciences draws scientific thought and poetic form into telling relation, disclosing how they were understood variously across the nineteenth century as both comparable and competing ways of knowing the physical world. Clearly written and beautifully structured, Nineteenth-Century Poetry and the Physical Sciences is both scholarly and accessible, a fascinating and indispensable contribution to its field. Daniel Brown, Professor of English at the University of Southampton, UK Essential reading for Victorianists. Tates study of nineteenth-century poetry and science reconfi gures debate by insisting on the equivalence of accounts of empirical fact and speculative theory rather than their antagonism. The undulatory rhythms of the universe and of poetry, the language of science and of verse, come into newrelations. Tate brilliantly re-reads Coleridge, Tennyson, Mathilde Blind and Hardy through their explorations of matter and ontological reality. He also addresses contemporary theory from Latour to Jane Bennett. Isobel Armstrong, Emeritus Professor of English at Birkbeck, University of London, UK.
