Weinberg gives a useful scorecard on the specific scientific howlers incorporated into the hoax article by Sokal. See the Weinberg article for the specifics, which are of only marginal interest to THE PROGRAMME as such.
Courtesy of the Deleuze/Guattari discussion list and Sokal himself, we obtained the full text of Alan Sokal's article, Transgressing the Boundaries--Toward a Transformative Hermeneutics of Quantum Gravity. The D&G discussion list had a flurry of commentary, signifiying little in the long run, except that Sokal's article, whatever its merits, hit an exposed nerve in the worlds of ideas about culture and science.
Sokal's page carries numerous comments on the hoax, or parody, as he calls it.
