This article continues NTQ's explorations, commenced in NTQ18 (1989) and NTQ23 (1990), of the interactions between theatrical performance and emerging views of nature coming out of the ‘new sciences’. Here, Michael Vanden Heuvel argues that analogies between quantum science and performance are productive mainly in reference to work which investigates the nature of perception, and which foregrounds the spectator's awareness of the ‘event-ness’ of theatrical performance. Models drawn from the new science of ‘chaotics’, on the other hand, appear more applicable to performances which seek to move beyond phenomenology into the sphere of cultural discourse. He offers as an example of this ‘post-quantum’ theatre the work of the renowned New York collective the Wooster Group, whose performances create a dialogics between order and disorder which acts to map dynamic interactions between hegemony and difference in American culture. Michael Vanden Heuvel is Assistant Professor of English and Interdisciplinary Humanities at Arizona State University. His Performing Drama/Dramatizing Performance: Alternative Theatre and the Dramatic Text was published by the University of Michigan Press in 1991, and he has written articles and reviews for Theatre Journal and Contemporary Literature.
