Gravity: Sokal's Academic Hoax

In 1996, physics professor Alan Sokal published an article in the academic journal Social Text. In it, he claimed that gravity is a fiction that people are made to believe. Almost none of the reviewers noticed that the articles had already been published, and nearly all of the reviewers said the articles had "serious methodological flaws." Later, he revealed it all to be a hoax to prove that 1) editors give more importance to academic authority and 2) damage of postmodern philosophy in science.
