Alan Sokal is Professor of Physics at New York University and Professor of Mathematics at University College, London. His main research interests are in statistical mechanics and quantum field theory. Among non-physicists, Sokal is probably best known for his famous parody of postmodern science criticism, known as the 'Sokal Hoax', which aroused fierce debate in cultural circles, and received widespread coverage in the media, including front-page stories in the <i>New York Times</i>, the <i>International Herald and Tribune</i>, the <i>Observer</i>, and <i>Le Monde</i>. Alongside many publications in physics, Sokal's previous books include <i>Intellectual Impostures</i> (with Jean Bricmont, Profile Books, 1998; published as <i>Fashionable Nonsense</i> by Picador in the US).
