'a demonstrative scholarly hoax performed by Alan Sokal...to test the journal's intellectual rigor, specifically to investigate whether "a leading North American journal of cultural studies...[would] publish an article liberally salted with nonsense if (a) it sounded good and (b) it flattered the editors' ideological preconceptions."
'The article, "Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity",[3] was published in the journal's spring/summer 1996 "Science Wars" issue. It proposed that quantum gravity is a social and linguistic construct. The journal did not practice academic peer review and it did not submit the article for outside expert review by a physicist.'

IMHO it is the most amazing academic comeuppance in history.
