In the Guardian now there is a longread on the background to this story, how Nick Brown found out that there was something wrong with an often quoted paper:
He went back over Losada’s equations and he noticed that if he put in the numbers Fredrickson and Losada had then you could arrive at the appropriate figures. But he realised that it only worked on its own terms. “When you look at the equation, it doesn’t contain any data. It’s completely self-referential.”
In a quote by Sokal, Brown, a student in his fifties (!) gets a lot of praise, the original research not really:
“The Lorenz equation Losada used was from fluid dynamics,” says Sokal, “which is not the field that I’m specialised in, but it’s elementary enough that any mathematician or physicist knows enough. In 10 seconds I could see it was total bullshit. Nick had written a very long critique and basically it was absolutely right. There were some points where he didn’t quite get the math right but essentially Nick had seen everything that was wrong with the Losada and Fredrickson paper.”
