year. In 1991 he published Ad Infinitum ... the Ghost in Turing’s Machine – a polemic against the ‘naturalness’ of the natural numbers. In the following years he received fellowships from Stanford Humanities Center, the National Endowment for the Humanities, and the American Council of Learned Societies. From 1996 to 1998 he was a professor of interdisciplinary studies in the English department at Louisiana State University in Baton Rouge, Louisiana and in 1998 moved to Columbus, Ohio to join the faculty of the Ohio State University, first as a professor in the Advanced Computing Center for the Arts and Design (ACCAD) and then as a member of the department of Comparative Studies. His students have called him both stunning and eccentric, and keen to bend disciplines. In 2000 he published Mathematics as Sign: Writing, Imagining, Counting, a collection of essays which gathered his writings on the semiotics of mathematics. More recently his work has focused on the gestural dimension of thought, inner speech, and the psychic effects produced by technological media, some of which, that concerned with the medium of writing, is elaborated in the book Becoming Beside Ourselves referred to above. In November 2012 he was invited by Goldsmiths College in London to choreograph a mathematical dance piece entitled Ordinal 5, which was performed at the Tate Modern.
