"Fashionable Nonsense" is a book by physicists Alan Sokal and Jean Bricmont that criticizes postmodern intellectuals for their misuse of scientific concepts. The authors argue that these intellectuals often use scientific terms in ways that are nonsensical or misleading, and that this can lead to confusion and misunderstanding.
The book includes examples of postmodern writings that misuse scientific concepts, such as quantum mechanics and chaos theory. Sokal and Bricmont argue that these writings often use scientific terms in ways that are not supported by the scientific literature. They also argue that these writings often make claims about science that are not supported by evidence.
