After the international success of Mnemonic, Complicite have once again brought science and drama together in a new theatre piece, A Disappearing Number. Both plays place scientists in the limelight, though their " scientific " content is very different: Mnemonic was based on the discovery of a Neolithic man in the Alps, and used neurology and archeology to explore notions of memory and history; A Disappearing Number focuses on our fascination with infinity, and dramatises the " mysterious and romantic mathematical collaboration " between G. H. Hardy and Srinivasa Ramanujan. The two pieces are, however, remarkably similar in plot and structure, and in their common exploration of the metaphorical and theatrical potential of scientific discourse. Moreover, they both use science as a narrative tool to explore our relation to time and mortality. This review presents them in parallel and examines the particular integration of ideas and aesthetics which characterises Complicite " s work: a tireless search for connections, and a constant translation of ideas between different theatrical languages, be they verbal, visual or musical.
