Modernist Physics contributes to the growing field of literature and science as well as to the popular field of modernist studies and to research on Virginia Woolf and D. H. Lawrence in particular. It combines history of science with literary history and literary analysis, considering both literary texts and scientific ideas in their historical context, as well as exploring a range of other disciplines which were drawing on similar ideas in the late nineteenth and early twentieth centuries. Famous scientific ideas like relativity are explored, although specifically through Lawrence’s distinctive take on Einstein’s theories. Less familiar scientific ideas are also explained and examined, specifically wave-particle duality, complementarity, and Brownian motion.
